    Although the diagnosis of thymolipoma has improved with the introduction of computerized tomography (CT), variations in CT appearance are still being described; this paper describes a case which resembled a lipoma. The CT features of thymolipoma are discussed with special reference to the differential diagnosis. Surgical excision should be considered for patients who are found to exhibit a fatty intrathoracic mass on CT.

    Two cases of late second trimester extrauterine pregnancy are presented--intraabdominal pregnancy in one and an ampullary pregnancy in another. In the former the diagnosis was made only after attempts at induction of labour for fetal death with prostaglandins failed and in the latter only at laparotomy. The diagnostic and surgical problems encountered are discussed.

    Having an organized, structured thinking process is critical in medicine. It is through this thinking process that enables one to go through the method of history-taking, which will eventually lead to making a definitive diagnosis and all other processes that follow. The use of mnemonic has been found to be useful for this purpose. The mnemonic VITAMINSABCDEK, is a convenient and practical way to assist in expanding the differential diagnoses and covers all possible causes of an illness. It is also easy to remember, as the vitamins whose letters are represented in this mnemonic cover the entire range of vitamins known.

    The clinicopathological conference, popularly known as CPC primarily relies on case method of teaching medicine. It is a teaching tool that illustrates the logical, measured consideration of a differential diagnosis used to evaluate patients. The process involves case presentation, diagnostic data, discussion of differential diagnosis, logically narrowing the list to few selected probable diagnoses and eventually reaching a final diagnosis and its brief discussion. The idea was first practiced in Boston, back in 1900 by a Harvard internist, Dr. Richard C. Cabot who practiced this as an informal discussion session in his private office. Dr. Cabot incepted this from a resident, who in turn had received the idea from a roommate, primarily a law student.

    Although all types of tumour and tumour-like conditions have been described to occur in the clavicle, they only contribute to less then 0.5% of all skeletal tumours. The incidence of primary chondrosarcoma of the clavicle is extremely rare. To our knowledge it has not been reported in Malaysia. We would like to highlight the possibility of chondrosarcoma as a differential diagnosis for a clavicular lesion.

    Nausea and vomiting are common in early pregnancy affecting 70-80 percent of pregnant mothers. In a majority of women vomiting begins between 4-7 weeks of pregnancy. Nausea and vomiting are usually mild and self-limiting, however some of the mothers have a more profound course which lead to hyperemesis gravidarum. Careful clinical evaluation is necessary to exclude underlying medical illnesses or non pregnancy related causes of severe vomiting. Hyperemesis gravidarum poses health risk to both mother and baby, therefore prompt treatment should be initiated without delay. Non pharmacotherapy such as dietary modification and emotional support are useful. Pharmacotherapy with antiemetics, pyridoxine, methylprednisolone are effective and relatively safe. Severe hyperemesis with dehydration and electrolyte imbalance may need hospitalisation for electrolyte and fluid replacement.

    OBJECTIVE: A case of oral metastatic follicular thyroid carcinoma is presented.

    BACKGROUND: Metastatic tumours are more frequent in older individuals and can be the only sign/symptom of an undiagnosed primary malignancy.

    CASE REPORT: A 69-year-old lady presented with an enlarging mandibular swelling. Incisional biopsy and imaging studies were suggestive of metastatic follicular thyroid carcinoma.

    CONCLUSION: Metastatic tumours should be considered in the differential diagnosis of mandibular swellings especially in older individuals.

    A 15-year-old Indian male patient presented with a history of pain and swelling in left mandible. Imaging studies revealed a well-defined unilocular radiolucency in the body of the mandible. Patient also gave the past history of the surgery of the jaws, which was histopathologically diagnosed as dentigerous cyst. Following this patient underwent incisional biopsy and later excisional biopsy. The histopathologic diagnosis for incisional biopsy was unicystic ameloblastoma but final diagnosis was dentinogenic ghost cell tumor for the excised tissue. To the best of our knowledge, this appears o be the first case of dentigerous cyst transforming into dentinogenic ghost cell tumor. The clinical presentation of the case, differential diagnosis and treatment modalities are being discussed.

    BACKGROUND: Lymphoepithelial cysts, which are benign and slow-growing tumours, usually involve the head and neck regions. Benign lymphoepithelial cysts (BLECs) are the most common cause of parotid swelling in human immunodeficiency virus (HIV)-positive patients and are less common in immunocompetent patients.

    CASE PRESENTATION: Here, we present two cases of immunocompetent patients with long-standing, progressively enlarging parotid swelling. Postoperative histopathological examination of these patients revealed features of BLEC.

    CONCLUSION: Wide surgical excision is the gold standard for treatment and recurrences is rare. These cases are of particular interest because of the rarity of BLEC in HIV-negative patients and highlight an important differential diagnosis of parotid swelling.

    Introduction: Leptospirosis is an acute febrile illness, known for its protean clinical manifestations and the challenge in differentiating from other infectious diseases. Standardized confirmatory test is antibody dependent and not accessible by the suburban community. This study measures efficiency of an immune-chromatographic assay, Leptocheck WB, in detecting acute leptospirosis.

    Methods: A total of 142 sera were used for kit evaluation. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated by comparing rapid kit results with gold standard laboratory, microscopic agglutination test (MAT).

    Results: We found this rapid kit to have a sensitivity and specificity of 66.6% and 78.9%, respectively, whereas the PPV and NPV of the kit appeared to be 73.3% and 73.2%, respectively.

    Discussion: Test efficiency of this rapid kit is reasonable. It is specific in detecting leptospiral antibody and assures clinician of accurate diagnosis by having higher PPV and NPV. It is prompt and efficient in comparison with conventional methods in assisting differential diagnosis. High sensitivity and specificity leptospirosis rapid test is indeed a crucial measure to assist the diagnosis of acute undifferentiated febrile illnesses.

    Neurological disorders (NDs) are often fatal to horses. Thus, symptoms of equine NDs commonly indicate euthanasia. Current diagnostic approaches for equine NDs is based on clinical signs, differential diagnoses, analysis of cerebrospinal fluid (CSF), assessment of histopathological lesions, and imaging. However, advances in biofluid biomarkers in the diagnosis of human neurological diseases can potentially be applied to equine NDs. In this review, we described the established human blood and CSF neurobiomarkers that could potentially be used to diagnose equine NDs.

    BACKGROUND: Diagnosis of malignant peripheral nerve sheath tumor (MPNST) is rather challenging due to its divergent morphologic heterogeneity and lack of specific ancillary test. The emergence of H3K27 trimethylation (H3K27me3) as a new immunohistochemistry (IHC) marker for MPNST have recently available to assist pathologists in differentiating MPNST from other histologic mimics. We aim to study the expression pattern of H3K27me3 in MPNST and its histologic mimickers and their association with the clinicopathological data.

    METHODOLOGY: A total of 59 benign and malignant spindle cell tumours (18 MPNST and 41 of its histologic mimickers which included 10 schwannoma, 13 neurofibroma, 4 synovial sarcoma, 3 fibrosarcoma, 2 gastrointestinal stromal tumour (GIST), 4 leiomyosarcoma, 1 spindle cell liposarcoma, 1 solitary fibrous tumour, 2 low grade fibromyxoid sarcoma and 1 unclassified spindle cell sarcoma), diagnosed from January 1998 to April 2018 in Hospital Universiti Sains Malaysia (HUSM) were tested for H3K27me3 by IHC. The MPNST histological grade was assessed based on the French Fe'de' ration Nationale des Centres de LutteContre le Cancer (FNCLCC) for 3 tiers system (low grade, intermediate grade and high grade). The clinicopathological data were retrieved from the patients' record.

    RESULTS: A total of 61.1% (11/18 MPNST) showed loss of H3K27me3 expression which is statistically significant as compared to its histologic mimics (p<0.001). Similar findings (p=0.026) were also observed in high grade MPNST (81.8%), intermediate grade MPNST (100%) and 0% in low grade MPNST.

    CONCLUSION: H3K27me3, combined with other panel of markers, is useful in MPNST diagnosis to differentiate it from the histological mimickers.

    Kimura's disease is rare chronic inflammatory disease with a distinct clinicopathological entity. It has three major components; inflammatory, vascular and fibrosis. It has to be considered as a differential diagnosis in young patient presenting with head and neck swelling. Although of unknown aetiology many hypothesis has been postulated. Inflammation is the most prominent and predominating characteristic in this disease. Although reported to be predominant in Asian literature regarding this disease is scanty. We report a complete clinical-radiological and pathological picture of this disease.

    Synchronous primary non-small cell lung cancers (NSCLC) are rare and may be discovered unexpectedly following lung resection. Discrimination from intrapulmonary metastases is important to guide treatment and prognosis but is difficult solely on clinical or radiological findings. Histopathological evaluation with immunohistochemistry (IHC) markers can prove decisive and should feature in the diagnostic algorithm of such patients. We report a rare case of two synchronous primary NSCLCs diagnosed post operatively following pathological examination of the resected lobe, highlighting the value of IHC and discuss the management of such patients.
