    'Pai syndrome' (PS) is a rare congenital syndrome. Presented here, a new-born baby-girl who exhibited the characteristic features of having a midline nasal (septal) polyp, an anterior alveolar process polyp, and a pericallosal lipoma associated with corpus callosum dysgenesis of the brain. Both polyps were lined with stratified-squamous epithelium. The overall features were largely consistent with those described by Pai et al., in 1987. A midline cleft-lip (with or without cleft-alveolus) is one of the most common features of the syndrome which was however absent in this case. Instead, an anterior alveolar polyp is present, which is relatively rare.

    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.

    We report a unique case of differentiated thyroid carcinoma (DTC) with squamous metaplasia complicated with chronic discharging ulcer. A 76-year-old gentleman was referred to us after defaulted treatment 1 year post-total thyroidectomy. He presented to us with long-standing chronic, non-healing, ulcerative and discharging wound at the anterior neck at previous total thyroidectomy scar. The primary tumour was histologically diagnosed as papillary malignant cells with extensive squamous metaplasia. Squamous metaplasia is a rare finding in thyroid carcinoma that carried a poorer prognostic factor.

    Cervix cancer is about twice as common in Asia as in the Western world and its incidence varies among different Asian ethnic groups. A study based in Singapore, the population of which comprises Chinese, Indians and Malaysians, offers the opportunity to evaluate whether the same risk factors are important in this part of the world as in the West. A total of 135 cases and an equal number of controls were interviewed and details concerning reproductive and sexual history, smoking, hygiene, socio-economic status and education were collected. Seventy-three cases had invasive cancer while 62 had micro-invasive disease or CIN III. The most important risk factors were parity and number of sexual partners. Smoking was rare in cases and controls and did not appear to be an important determinant of risk. Of the socio-economic factors, education appeared most predictive and lowered the risk. Age at first intercourse was strongly correlated with education (positively) and parity (negatively), but not with number of sexual partners. Biopsies were available for HPV DNA analysis in 38 cases and 37% were positive, mostly for HPV type 16. All these factors gave similar risks in invasive and preinvasive disease.

    Introduction:A unilateral enlarged tonsil always is a suspicion of carcinoma. Especially if it is with fungating ulcer-ative surface. Neoplasms in unilaterally enlarged tonsil include squamous cell carcinomas and lymphomas. Lym-phomas in oropharynx are not common specially with fungating surface. Usually lymphomas in these areas are Non-Hodgkin’s type. Case description: A 62-year-old woman was admitted in the tertiary level hospital of Kota Kinabalu, Sabah, with the complaint of sore throat, odynophagia and right neck swelling. She was treated as a case of acute tonsillitis by general practitioner without any noticeable improvement. Oral cavity examination revealed a hugely enlarged right tonsil with fungating ulcerative surface and almost obstructing the oropharynx. Trismus was seen which make the examination difficult. A non-tender right upper neck swelling was palpable. All baseline lab-oratory investigations were normal. A contrast-enhanced computed tomography (CECT) showed a heterogeneously enhancing mass at oropharynx compromising the airway, right supraclavicular lymphadenopathy. Histology of biop-sy from right tonsillar mass showed High grade B-cell lymphoma. Chemotherapy was planned. First cycle of chemo-therapy was administered, Patient was discharged home with the complete plan of chemotherapy. Conclusion: This patient was clinically suspicious of carcinoma of palatine tonsil. But later proven as high grade B-cell lymphoma. All unilateral enlarged tonsils are not always carcinoma.

    Lymphoma is generally a nodal disease and arises from lymphoid tissues or organs. Extranodal lymphoma accounts for almost a third of malignant lymphomas. Squamous cell carcinoma accounts for 90 % of laryngeal carcinoma, while extranodal Non Hodgkin Lymphoma (NHL) attributes only less than 1% of laryngeal neoplasms. Less than 100 of such cases been reported in literature since 1952. As to our best knowledge, no such case was ever reported in our country. We report a case of a 58-year-old gentleman who presented the typical history of laryngeal malignancy however the pathology turned out to be as NHLof Diffuse Large B-cell subtype.

    Basal cell carcinoma (BCC) of the scrotum is uncommon and its pathogenesis is not well understood. The clinical behaviour of scrotal BCC is thought to be more aggressive and has a higher metastatic potential than BCC of other regions. The mainstay of treatment for localized scrotal BCC is wide local excision, while metastatic disease may need systemic chemotherapy for palliative control. A rare clinical scenario of scrotal BCC presenting concurrently with another metastatic cancer has never been reported. The present case illustrates the diagnostic challenge and management dilemma due to simultaneous presentation of scrotal BCC and metastatic squamous cell carcinoma (SCC). A 70-year-old man complained of a non-healing scrotal ulcer while he was being investigated for metastatic squamous cell carcinoma (SCC) of the external auditory meatus. The scrotal lesion was initially thought to be metastatic SCC. It was later confirmed to be BCC with biopsy and histopathological examination. He underwent surgical resection of the scrotal BCC for local control followed by palliative chemotherapy with cisplatin and radiotherapy for lymph node metastases. He remained well and did not have any local recurrence following 6 months after palliative treatment. Surgery coupled with palliative chemoradiation can offer good quality of life for patients with scrotal BCC and concurrent metastatic SCC.

    One of the main aims of cancer chemopreventive studies is to identify ideal apoptotic inducers, especially examples which can induce early apoptotic activity. The present investigation focused on chemopreventive effects of a hydrazone derivative using an in vitro model with tongue cancer cells. Alteration in cell morphology was ascertained, along with stage in the cell cycle and proliferation, while living-dead status of the cells was confirmed under a confocal microscope. In addition, cytotoxicity test was performed using normal mouse skin fibroblast cells. The results showed that the compound inhibited the growth of tongue cancer cells with an inhibitory concentration (IC₅₀) of 0.01 mg/ml in a dose and time-dependent manner, with a two-fold increase in early apoptotic activity and G0G1 phase cell cycle arrest compared to untreated cells. Exposure to the compound also resulted in alterations of cell morphology including vacuolization and cellular shrinkage. Confocal microscope analysis using calcein and ethidium staining confirmed that the compound caused cell death, whereas no cytotoxic effects on normal mouse skin fibroblast cells were observed. In conclusion, the findings in this study suggested that the hydrazone derivative acts as an apoptotic inducer with anti-proliferative chemopreventive activity in tongue cancer cells.

    Background: Cervical cancer is a preventable disease caused by human papillomaviruses. It is the third most
    common cancer to occur in women of reproductive age. The ADAM9 protein plays a role in basement membrane
    degradation and tumour metastasis in certain types of tumour. Thus, it has the potential to become a new targeted
    therapy. The objective of this study was to investigate ADAM9 expression in cervical cancer and to determine the
    factors associated with ADAM9-positive expression. Methods: This cross-sectional study was conducted in Hospital
    Universiti Sains Malaysia (HUSM) Kelantan, Malaysia from December 2010 to December 2012. Histological slides
    obtained from 95 cervical cancer cases diagnosed and/or treated in HUSM from 2000 to 2010 were analysed. The
    ADAM9 immunostain was then performed on the paraffin blocks. The statistical data entry and analysis were done
    using SPSS version 18.0. Multiple logistic regression analysis was performed to determine the factors associated with
    ADAM9-positive expression. Result: Of the 95 cervical cancer patients included in the study, 72 (75.8%) patients showed
    positive ADAM9 expression. The mean age of the patients was 53.89 (10.83) years old. Squamous cell carcinoma was
    the most common type of cervical cancer (n = 67, 70.5%). Factors that showed a statistically significant association
    with ADAM9-positive expression were tumour size (adjusted odds ratio [adj. OR]: 1.08; 95% confidence interval
    [CI]: 1.02, 1.13; p = 0.004), distant metastasis (adj. OR: 12.82; 95% CI: 1.91, 86.13; p = 0.009) and the histological
    type of cervical cancer (i.e. squamous cell carcinoma) (adj. OR: 7.39; 95% CI: 1.42, 38.51; p = 0.017). Conclusion:
    The ADAM9 immunostain was consistently positive in malignant cells. Thus, ADAM9 expression can be used as a
    prognostic/therapeutic indicator in aiding clinician decision-making regarding patient treatment (targeted therapy).

    Oral squamous cell carcinoma (OSCC) is a lethal disease with a 5-year mortality rate of around 50%. Molecular targeted therapies are not in routine use and novel therapeutic targets are required. Our previous microarray data indicated sphingosine 1-phosphate (S1P) metabolism and signalling was deregulated in OSCC. In this study, we have investigated the contribution of S1P signalling to the pathogenesis of OSCC. We show that the expression of the two major enzymes that regulate S1P levels were altered in OSCC: SPHK1 was significantly upregulated in OSCC tissues compared to normal oral mucosa and low levels of SGPL1 mRNA correlated with a worse overall survival. In in vitro studies, S1P enhanced the migration/invasion of OSCC cells and attenuated cisplatin-induced death. We also demonstrate that S1P receptor expression is deregulated in primary OSCCs and that S1PR2 is over-expressed in a subset of tumours, which in part mediates S1P-induced migration of OSCC cells. Lastly, we demonstrate that FTY720 induced significantly more apoptosis in OSCC cells compared to non-malignant cells and that FTY720 acted synergistically with cisplatin to induce cell death. Taken together, our data show that S1P signalling promotes tumour aggressiveness in OSCC and identify S1P signalling as a potential therapeutic target.

    Confirmation of oral squamous cell cancer (OSCC) currently relies on histological analysis, which does not provide clear indication of cancer development from precancerous lesions. In the present study, whole saliva proteins of patients with OSCC (n = 12) and healthy subjects (n = 12) were separated by 2DE to identify potential candidate biomarkers that are much needed to improve detection of the cancer. The OSCC patients' 2DE saliva protein profiles appeared unique and different from those obtained from the healthy subjects. The patients' saliva α1-antitrypsin (AAT) and haptoglobin (HAP) β chains were resolved into polypeptide spots with increased microheterogeneity, although these were not apparent in their sera. Their 2DE protein profiles also showed presence of hemopexin and α-1B glycoprotein, which were not detected in the profiles of the control saliva. When subjected to densitometry analysis, significant altered levels of AAT, complement C3, transferrin, transthyretin, and β chains of fibrinogen and HAP were detected. The increased levels of saliva AAT, HAP, complement C3, hemopexin, and transthyretin in the OSCC patients were validated by ELISA. The strong association of AAT and HAP with OSCC was further supported by immunohistochemical staining of cancer tissues. The differently expressed saliva proteins may be useful complementary biomarkers for the early detection and/or monitoring of OSCC, although this requires validation in clinically representative populations.

    Adenoid cystic carcinoma (ACC) is a rare malignant tumor that arises within secretary glands, most commonly the major and minor salivary glands. It has a tendency for a prolonged clinical course, perineural invasion, with local recurrences and distant metastases. The three recognized histopathologic pattern of ACC are cribriform, tubular, and solid with the cribriform being most common. Standard treatment for salivary gland ACC is surgery and postoperative radiotherapy. We report a case of ACC of palate in a 30-year-old female and review the literature.

    Introduction: Ductal Eccrine carcinoma (DEC) is a rare primary cutaneous tumor that exhibits both squamous and adnexal ductal differentiation. Due to its rarity in clinical practice we present as case of DEC and a literature review on the latest management of this rare disease.

    Case presentation: We report a case 41 years old female presented with lesion on the scalp and sternal mass, increasing in size with itchiness and erythematous for 6 months duration. Further CECT scan of brain and neck shows features of malignant left frontal scalp lesion with poor plane with overlying skin and underlying skull bone and CECT of thorax shows a large, irregular heterogeneously enhancing mass with necrotic center noted at right hilar within superior segment of right lower lobe, encasing right middle and lower lobe bronchi. Wedge biopsy of scalp lesion showed an intradermal lesion extensively infiltrating by malignant gland accompanied by desmoplasia and the tumor cells are seen extending into the surgical margins suggestive of ductal eccrine carcinoma.Clinical Discussion:This case highlights the importance and challenges in achieving early diagnosis coupled with the scarcity of information on these leads to difficulty in managing this patient.

    Conclusion: In managing Ductal Eccrine Carcinoma tumor, standard method of treatment for has not been established. However, wide surgical excision is the treatment of choice for localized lesions. Regarding prognosis, there is conflicting data published which we describe in this article.

    Some oral verrucal lesions may constitute parts of the clinicopathological spectrum of proliferative verrucous leukoplakia (PVL). Because of its idiopathic yet sinister nature, it is possible that PVL may exist in other populations. The aim of this study was to review the clinicopathological features of persistent, multifocal, oral verrucal lesions in Malaysian population.
