    Differential diagnosis of orofacial pain is crucial, as the course of each process and its clinical management varies markedly. A case is illustrated here of trigeminal neuralgia in a 49-year-old Indian female whose complaint was initially diagnosed as dental pain leading to sequential extractions of her right mandibular and maxillary molars but with no pain abatement. Subsequent neurological assessment diagnosed her complaint as trigeminal neuralgia but pain remained poorly controlled even with high doses of carbamazepine and gabapentin. A dental referral and orthopantomographic examination revealed multifocal sclerotic masses in her jaws, suggestive of florid cemento-osseous dysplasia (FCOD). Right mandibular incisional biopsy confirmed the diagnosis. A decision was made to curette the right mandibular masses and lateralised the right inferior dental nerve. Follow-up disclosed considerable pain reduction. This case raises the issue as to whether the sclerotic bone masses in FCOD may have caused nerve compression which
    aggravated her neuralgic pain.

    Ocular inflammation from various causes may have similar clinical presentation thus careful clinical evaluations are mandatory particularly when the disease appear to be resistant to treatment. This paper reports a case of ocular lymphoma which was initially treated as Vogt Koyanagi Harada disease at a different centre. A 65-year-old Sudanese man complained of gradual worsening left eye vision. Careful ocular and slit lamp examination revealed a conjunctival lesion with choroidal infiltration as well as exudative retinal detachment. Computed tomography scan (CT scan) showed left eye axial proptosis, and a homogenous enhancing mass at the posterior coat of the globe. Tissue biopsy of the conjunctival lesion revealed marginal Zone B cell (MALT type), low grade, non-Hodgkin’s lymphoma. AS the ocular signs and symptoms progressed, chemotherapy was initiated. The proptosis, exudative retinal detachment, disc hyperemia and swelling improved after chemotherapy. The post treatment CT scan showed reduction of the posterior ocular coat mass. The possibility of malignant lymphoma should be considered in patients with resistant uveitis despite administration of corticosteroid. Ocular lymphoma is an indolent tumour with good prognosis. Careful ocular examination, adequate imaging studies followed by early surgical biopsy will contribute to early diagnosis.

    Kveim tests using a validated material have been undertaken in Malaysia on 39 patients (32 Chinese; 4 Malay and 3 Aboriginal) with lepromatous or tuberculoid leprosy. All the patients had been treated for leprosy, most for two or more years. The tests were read microscopically. Of the 21 lepromatous patients one gave a weak positive and two an equivocal Kveim test whereas four of the nine tuberculoid patients gave equivocal or weak Kveim positivity. Only the tuberculoid form elicits a higher proportion of granulomas than might be expected in a comparable normal population. Of nine patients (8 lepromatous; 1 tuberculoid ) who failed to sensitize well to tuberculin
    following two BCG vaccinations, two gave equivocal Kveim tests similar in appearance to those in the other groups.

    A review of incident oral and maxillofacial biopsies in Kelantan from January 1994 to December 1998 was carried out to evaluate the scope of pathological lesions managed by the two main oral and maxillofacial units in this state. A total of 357 biopsy reports from incident cases of pathological lesions were reviewed. The biopsies were mainly from intra-oral sites (n=326, 91.3%). Females had more frequent oro-facial lesions compared with males (male:female ratio is 0.8:1). The Bumiputera ethnic group had the most number of biopsies (n=321; 90%). The three most commonly observed histopathological groups were the connective tissue hyperplasia (n=90; 25.2%), epithelial dysplasia and neoplasia (n=68; 19%) and salivary gland cysts/mucocele (n=56; 15.7%). The top five most frequent diagnoses were mucocele (n=56; 15.7%), squamous cell carcinoma (n=45; 12.6%), epulides (n=31; 8.7%), pyogenic granuloma (n=25; 7.0%) and fibroepithelial polyp (n=19; 5.3%). Oro-facial malignancies made up almost one-fifth of all diagnoses and squamous cell carcinoma was the most common sub-type. Lymphomas in the oro-facial region (n=8; 11.4%) were more common than basal cell carcinoma (n=7; 10%) and salivary gland malignancies (n=6; 8.5%). Epithelial jaw cysts consisted of 8.7% (n=31) of all diagnoses, where inflammatory types were more common than the developmental types. Odontogenic tumours consisted of 5.6% (n=20) of all diagnoses and ameloblastoma was the predominant type.

    Three cases of schistosomiasis in 2 Filipinos and one Chinese in Sabah are reported. Diagnosis was based on incidental histological findings of Schistosoma japonicum-like ova in the liver and rectal biopsies. As these 3 patients are immigrants to Sabah, it is assumed that they are imported cases, and that Sabah has been free of the disease from 1970 to 1977.

    Anaplastic large cell lymphoma (ALCL) is a rare tumour, accounting for approximately 3% of adult non-Hodgkin lymphomas.1 Primary systemic ALCL frequently involves both lymph nodes and extranodal sites. A 44-year-old woman presented with a firm, mobile mass in the left iliac fossa region. Ultrasound findings showed a well defined inhomogenous soft tissue mass, measuring 4x4x2.6cm in the deep subcutaneous region. Histopathological examination revealed that the mass was infiltrated by large lymphoid cells with marked nuclear atypia including kidney-shaped nuclei. These neoplastic cells expressed anaplastic lymphoma kinase (ALK) (both nuclear & cytoplasmic staining), CD30 and EMA but not for T-cell (CD45RO and CD3), and B-cell (CD20 & CD79α) markers. Fluorescence in situ hybridization (FISH) analysis showed a t(2;5)(p23;q35) chromosomal translocation. Subsequently the patient developed shortness of the breath and a thoracic computed tomography (CT) scan showed a mass encasing the right upper lobe bronchus. She also had bilateral axillary lymph nodes, measuring 1 cm in diameter (biopsy was not done). The mediastinum and endobronchial region did not show any abnormalities. She received 6 cycles of CHOP chemotherapy and remained disease free 2 years after diagnosis. ALCL, rarely present as a soft tissue tumour and this disease should be included as a differential diagnosis of any soft tissue mass.

    Melanosis coli denotes brownish discoloration of the colonic mucosa found on endoscopy
    or histopathologic examination. The condition has no specific symptom on its own. It is a fairly frequent incidental finding of colonic biopsies and resection specimens. The pigmentation is caused by apoptotic cells which are ingested by macrophages and subsequently transported into the lamina propria, where lysosomes use them to produce lipofuscin pigment, not melanin as the name suggests. Melanosis coli develops in over 70% of persons who use anthraquinone laxatives (eg cascara sagrada, aloe, senna, rhubarb, and frangula), often within 4 months of use. Long-term use is generally believed to be necessary to cause melanosis coli.The condition is widely regarded as benign and reversible, and disappearance of the pigment generally occurs within a year of stopping laxatives. Although
    often due to prolonged use of anthraquinone, melanosis can probably result from other factors or exposure to other laxatives. It has been reported as a consequence of longstanding inflammatory bowel disease. Some investigators suggested that increase in apoptosis of
    colonic mucosa by anthraquinone laxatives increased the risk of colonic cancer. Recent data, including those from large-scale retrospective, prospective and experimental studies, did not show any increased cancer risk.

    We report a 26-year old lady who presented with chronic cough and breathlessness associated with subtle
    TB symptoms for 1 year. Her CT thorax showed multiple cavitating pulmonary nodules with mediastinal and
    cervical lymphadenopathy. Cervical lymph node biopsy and CT-guided pulmonary biopsy at our centre
    confirmed the diagnosis of Hodgkin’s lymphoma with pulmonary infiltrations. She was successfully treated
    with ABVD regime but later developed life-threatening bleomycin-induced pulmonary fibrosis. Sadly, she
    succumbed to respiratory failure due to severe pneumonia with possibility of bleomycin-induced pulmonary
    fibrosis. Multiple cavitating pulmonary nodules secondary to lymphoma is rare and in TB endemic area, it
    may result in delayed diagnosis and treatment.

    A 43-year-old Malaysian man with well-controlled HIV infection on combination antiretroviral therapy presented with a six-week history of a widespread rash. The patient was otherwise well but was developing new lesions on a daily basis. Referral to Dermatology instigated punch biopsies, which revealed a diagnosis of lymphomatoid papulosis type A. This case highlights the importance of swift referral, especially in cases of spontaneous regression of symptoms, in order to obtain the correct diagnosis. In most patients, this condition tends to be chronic, with its chronicity and benign clinical course setting it apart from cutaneous anaplastic T-cell lymphoma and Hodgkin's disease, which are major entities in the histological differential diagnosis.

    A previously healthy 20-year-old man presented with prolonged intermittent low grade fever and cough for 6months. He had bilateral calf pain and lower limb weakness 2days prior to admission. Physical examination revealed multiple enlarged lymph nodes with hepatomegaly. There was bilateral calf tenderness with evidence of proximal myopathy. Full blood picture showed lymphocytosis with reactive lymphocytes and eosinophilia. Creatine kinase and lactate dehydrogenase were markedly elevated. Over 2 weeks of admission, patient was treated symptomatically until the muscle biopsy of right calf revealed eosinophilic myositis with muscular sarcocystosis. He was treated with albendazole and high-dose corticosteroids. Symptoms subsided on reviewed at 2weeks and the dose of corticosteroid was tapered down slowly over a month. Due to poor compliance, he was readmitted 1month later because of relapsed. High-dose corticosteroid was restarted and duration for albendazole was prolonged for 1month. His symptom finally resolved over 2weeks.

    Oral retinoids are among the drugs of choice for pustular psoriasis. Therapy with retinoids, including acitretin, is potent teratogens with other common side effects such as mucocutaneous involvement. Mucocutaneous side effects including dry lips (cheilitis), skin peeling, hair loss (alopecia), dry skin, or rhinitis are dose-related, with cheilitis occurring in more than 75% of patients receiving the highest doses of acitretin (75 mg/day). We report on a 37-year-old woman who developed folliculitis with acitretin which is a rare cutaneous side effect. She presented with eruptions pruritic papules with follicular pattern on anterior thigh and forearms after almost 1 year of treatment with acitretin (50mg OD) for pustular psoriasis. The skin lesion was treated successfully with skin dressing and antibiotic treatment and skin biopsy is suggestive of folliculitis. Several treatments for pustular psoriasis including topical steroids, methotrexate and oral prednisolone were ineffective or not tolerated. Treatment with acitretin which are 50mg OD provided partial resolution of skin lesions. The case is hereby reported because of its rarity and folliculitis must be considered in the differential diagnosis of a popular eruption, especially in patients with high dose acitretin.

    A 7-year-old, intact female Domestic Shorthair cat was referred to University Veterinary Hospital (UVH), UPM for diagnostic workup of a hepatomegaly observed on abdominal radiographs. Physical examination revealed no significant findings except for a distended abdomen. Hematology and serum biochemistry findings included a regenerative anaemia, left shift neutrophilia and a 10-fold elevation in gamma-glutamyltranspeptidase (GGT). Abdominal ultrasound revealed heterechoic liver lobes with irregular margins and presence of nodular and cyst-like structures predominantly affecting the left lobes. A mild ascites was also noted. A fine needle aspiration of the liver was performed and cytology results confirmed a cholangiocarcinoma. Generally, the outcome for cholagiocarcinoma is poor and there is limited information regarding the prognosis for patients with cholangiocarcinoma following chemotherapy or surgery.

    Introduction: Suspicious adnexal masses need to be investigated thoroughly as it may represent ovarian cancer, which is the fourth most common gynaecological cancer in Malaysia. Conventional cross sectional imaging may reveal non-specific findings, thus lead to unnecessary biopsies. 18F-Fluorodeoxyglucose positron emission tomography/ computed tomography (18F-FDG PET/CT) has emerged as a useful tool, for characterization of indeterminate adnexal masses. Most studies have been conducted in Western population, and little information is available in Asian population in general and Malaysian population in particular. Methods: Prospective study of women with suspicious adnexal masses, referred to the Centre for Nuclear Diagnostic Imaging, Universiti Putra Malaysia to undergo pre-operative whole-body contrast-enhanced 18F-FDG PET/CT scans from January 2014 to January 2016. Subjects underwent Contrast-Enhanced Computed Tomography (CECT) scans followed by positron emission tomography (PET) scans using a hybrid scanner. Two radiologists analyzed the CECT and PET/CT images by consensus; blinded to the HPE results. Then the PET/CT findings were correlated with HPE results as the gold standard. Results: 11 whole-body PET/CT scans and 18 adnexal masses (12 HPE-proven malignant lesions and 6 benign lesions) were analyzed. The sensitivity, specificity, PPV, and NPV of CECT alone compared to PET/CT was 91.7%, 50.0%, 78.6%, and 75.0% vs. 91.7%, 100%, 100% and 85.7% respectively. Conclusions: Improved diagnostic accuracy for characterizing benign and malignant adnexal masses can be achieved using contrast-enhanced 18F-FDG PET/CT, making it a potential investigation of choice which can help in treatment planning.

    We reported a case of primary renal lymphoma (PRL) presented with non-oliguric acute kidney injury and bilateral kidney infiltrates in an individual with human immunodeficiency virus (HIV) disease. Acute kidney injury secondary to lymphoma infiltrates is very rare (less than 1% of hematological malignancy). A 37-year-old gentleman with underlying human immunodeficiency virus (HIV) disease was on combined antiretroviral therapy since diagnosis. He presented to our center with uremic symptoms and gross hematuria. Clinically, bilateral kidneys massively enlarged and were ballotable. Blood investigations showed hemoglobin of 3.7 g/L, urea of 65.6 mmol/L, and serum creatinine of 1630 µmol/L with hyperkalemia and metabolic acidosis. An urgent hemodialysis was initiated, and he was dependent on regular hemodialysis subsequently. Computed tomography renal scan showed diffuse nonenhancing hypodense lesion in both renal parenchyma. Diagnosis of diffuse large B cell lymphoma with germinal center type, CD20 positive, and proliferative index 95% was confirmed via renal biopsy, and there was no bone marrow infiltrates. Unfortunately, the patient succumbs prior to initiation of chemotherapy.

    Introduction: Massive localised lymphedema (MLL) is considered a rare large, pendulous localised benign overgrowth of lymphoproliferative tissue commonly seen in patients with morbid obesity. Histologically, it may be mistaken for well-differentiated liposarcoma; hence, it is also known as pseudosarcoma.

    Presentation of case: We describe the successful management of MLL of the left medial thigh in a 35-year-old man weighing 220 kgs (BMI 80.8 kgs/m2). He underwent a concurrent laparoscopic sleeve gastrectomy with surgical resection of the MLL. He recovered well and during our last follow up six months after the operation, he is ambulating well and weighs 148 kgs (BMI 54.4 kgs/m2).

    Discussion: MLL is a form of secondary lymphedema resulting in disruption or compression of normal lymphatic drainage due to fat accumulation in obese patients. Patients usually delay treatment for even up to a decade, when it becomes sufficiently large enough to restrict mobility and daily activities, or when it becomes infected. MLL is primarily a clinical diagnosis. A detailed history regarding its slow growth spanning over the years makes malignancy less likely. However, if left untreated, MLL may progress to angiosarcoma. Imaging studies such as computed tomography (CT) and a Magnetic Resonance Imaging (MRI) are usually performed to rule out malignancy or vascular malformations. A tissue biopsy is not recommended unless there are suspicious pigmented lesions.

    Conclusion: MLL remains to be underdiagnosed. Due to the obesity epidemic, clinicians must be aware of this once rare disease. The role of concurrent bariatric surgery with surgical resection of MLL warrants further studies.

    Aims and objectives: Helicobacter pylori has been classified as high priority pathogen by the WHO in 2017. The emergence of antibiotic-resistant strains is one of the main causes of treatment failure in H. pylori infection. This study determined and characterized primary and secondary resistances in H. pylori in Malaysia.

    Materials and methods: Gastric biopsies from antrum (n=288) and corpus (n=283) were obtained from 288 patients who underwent endoscopy at Universiti Kebangsaan Malaysia Medical Center (UKMMC), Kuala Lumpur, Malaysia. Antibiotic susceptibility to six classes of antibiotics was determined by the E-test. Mutations conferring in resistance in functional genes were identified by PCR and sequencing.

    Results: Overall resistance rates to metronidazole, clarithromycin and levofloxacin were 59.3% (35/59), 35.6% (21/59) and 25.4% (15/59), respectively. Secondary isolates showed significantly higher resistance rates to clarithromycin compared to the primary isolates. Mixed infection with susceptible and resistant isolates was observed in 16.2% (6/37) of cases, of which 83.3% (n=5) had infection with the same strain. 41% (18/44) of isolates were resistant to more than one class of antibiotics of which 50% (9/18) were multidrug-resistant, two being primary and seven being secondary isolates. Mutations in rdxA, 23S rRNA and gyrA genes were associated with resistance to metronidazole, clarithromycin and levofloxacin, respectively.

    Conclusion: The high level of resistance to metronidazole, clarithromycin and levofloxacin seen in H. pylori isolates in our setting warrants the need for continuous surveillance and highlights caution in use of antibiotics generally used as first-line therapy in H. pylori eradication regimen.

    Melanonychia striata is characterized by a tan, brown, or black longitudinal streak within the nail plate that runs from the proximal nail fold to the distal part of the nail plate. Melanonychia striata is due to increased activity of melanocytes or melanocytic hyperplasia in the nail matrix with subsequently increased melanin deposition in the nail plate. The most common cause of melanonychia striata associated with melanocytic activation is ethnic melanonychia which occurs in dark-skinned individuals. Other causes of melanonychia striata related to melanocytic activation include pregnancy, chronic local trauma, infections, medications, dermatological disorders, endocrine disorders, alkaptonuria, hemochromatosis, porphyria, graft-vs-host disease, Peutz-Jeghers syndrome, and Laugier-Hunziker syndrome. Causes of melanonychia striata associated with melanocytic hyperplasia include nail matrix melanocytic nevus, nail lentigo, and nail apparatus/subungual in situ and invasive melanoma. In most cases, melanonychia striata is a benign condition, especially in children. Consequently, most investigators advocate a wait-and-see approach. Nail apparatus/subungual melanoma should be suspected if there is an abrupt onset after middle age, personal or family history of melanoma, rapid growth, darkening of a melanonychia band, pigment variegation, blurry lateral borders, irregular elevation of the surface, a bandwidth >3 mm, proximal widening, associated nail plate dystrophy, single rather than multiple digit involvement, and periungual spread of pigmentation onto the adjacent cuticle and/or proximal and/or lateral nail folds (Hutchinson sign). Prolonged follow-up is mandatory for early detection of possible malignant changes.

    Brodie's abscess is a variety of subacute osteomyelitis with a long duration of presentation and intermittent pain. It usually involves the metaphyseal region of long bones of the lower limbs. Brodie's abscess of pelvic bone is very rare. Involvement of posterior ilium with gluteal syndrome is extremely unusual and can be easily missed or misdiagnosed. We present a 9-year old boy who reported to us with intermittent low back pain of three months duration without any other constitutional symptoms. Clinically, there was mild tenderness over the posterior ilium. Computed tomography showed a lytic lesion in the posterior ilium with a breach in the outer cortex. MRI and bone scan were suggestive of inflammatory pathology. Keeping infective, tubercular and benign bone tumors as differential diagnoses, open biopsy and curettage were done. Staphylococcus aureus was cultured and histopathology was suggestive of osteomyelitis. The patient received appropriate antibiotics for six weeks. He was asymptomatic till 18 months of follow up without any recurrence. We present this case because of its rarity and unusual presentation as gluteal syndrome and low back pain, and its resemblance to other pelvic and sacroiliac joint pathologies which are often missed or misdiagnosed in paediatric patients.
