    Oral leiomyomas are rare benign tumour of smooth muscle. The first case of oral leiomyoma was reported by Blanc in 1884 and since then more cases has been published following advancement in immunohistochemical study. This tumour has an excellent prognosis and recurrences are extremely rare. We report a case of a recurrent glossal leiomyoma in a patient with HIV infection and the lesion recurred one year after the first excision.

    BACKGROUND: Protective effects of calcium supplementation against colorectal adenomas have been documented in systematic reviews; however, the results have not been conclusive. Our objective was to update and systematically evaluate the evidence for calcium supplementation taking into consideration the risks of systematic and random error and to GRADE the evidence.

    METHODS: The study comprised a systematic review with meta-analysis and trial sequential analysis (TSA) of randomized controlled trials (RCTs). We searched for RCTs published up until September 2016. Retrieved trials were evaluated using risk of bias. Primary outcome measures were the incidences of any recurrent adenomas and of advanced adenomas. Meta-analytic estimates were calculated with the random-effects model and random errors were evaluated with trial sequential analyses (TSAs).

    RESULTS: Five randomized trials (2234 patients with a history of adenomas) were included. Two of the 5 trials showed either unclear or high risks of bias in most criteria. Meta-analysis of good quality RCTs suggest a moderate protective effect of calcium supplementation on recurrence of adenomas (relative risk [RR], 0.88 [95% CI 0.79-0.99]); however, its effects on advanced adenomas did not show statistical significance (RR, 1.02 [95% CI 0.67-1.55]). Subgroup analyses demonstrated a greater protective effect on recurrence of adenomas with elemental calcium dose ≥1600 mg/day (RR, 0.74 [95% CI 0.56-0.97]) compared to ≤1200 mg/day (RR, 0.84 [95% CI 0.73-0.97]). No major serious adverse events were associated with the use of calcium, but there was an increase in the incidence of hypercalcemia (P = .0095). TSA indicated a lack of firm evidence for a beneficial effect. Concerns with directness and imprecision rated down the quality of the evidence to "low."

    CONCLUSION: The available good quality RCTs suggests a possible beneficial effect of calcium supplementation on the recurrence of adenomas; however, TSA indicated that the accumulated evidence is still inconclusive. Using GRADE-methodology, we conclude that the quality of evidence is low. Large well-designed randomized trials with low risk of bias are needed.

    Mucosal malignant melanoma (MMM) is an aggressive tumour occurring in the upper respiratory tract. It is rare compared to malignant melanoma of the skin. We report a case of a 53-year-old man with left paranasal swelling. A biopsy showed high-grade spindle cell tumour. Subsequently a subtotal maxillectomy was performed. Histopathological examination revealed a hypercellular tumour composed of mixed spindle and epitheloid cells with very occasional intracytoplasmic melanin pigment. The malignant cells were immunopositive for vimentin, S-100 protein and HMB-45. It was diagnosed as mucosal malignant melanoma (MMM). This article illustrates a rare case of MMM where the diagnosis may be missed or delayed without proper histopathological examination that include meticulous search for melanin pigment and appropriate immunohistochemical stains to confirm the diagnosis. Malignant melanoma can mimic many other types of high-grade malignancy and should be considered as a differential diagnosis in many of these instances.

    We describe a patient with multiple myeloma, who initially responded to chemotherapy and went into remission. She presented 10 months later with a right breast lump which was confirmed by core biopsy to be a plasmacytoma. Further treatment with radiotherapy, thalidomide and later second line chemotherapy appeared unsuccessful and she showed rapid disease progression with rising paraproteins and new extramedullary plasmacytoma lesions in the forehead, supraclavicular region, nasopharynx, liver, spleen, pancreas and paraaortic lymph nodes.

    Inverted papilloma is a rare, benign tumour representing only 0.5 to 4 per cent of all sinonasal neoplasms; its involvement of the middle ear is extremely rare. We present a case of multicentric inverted papilloma in the sinonasal region and middle ear in a 54-year-old man. The patient later developed neck metastasis secondary to malignant transformation of the inverted papilloma in the middle ear.

    Osteosarcomas are highly malignant neoplasms of bone that are challenging to diagnose. These neoplasms often show atypical behavior. In the initial phase they may present as nondescript bony swellings with an indolent growth rate, only to become overtly aggressive and malignant towards the later phase of the disease. Similarly, the histological growth pattern of this neoplasm can be quite diverse, presenting with areas that mimic benign myofibroblastic tumors, giant cell granulomatous conditions and partial encapsulation. The final diagnosis of an osteosarcoma is often reached after thorough sampling and examination of multiple biopsy specimens. All these clinical features and histological diagnostic difficulties were encountered in a case of osteosarcoma affecting the right mandible of a 62-year-old Chinese woman described here. The diagnostic lessons accrued from this case are discussed.

    780 breast cytology samples obtained over a one year period at the Breast Clinic of the University Hospital, Kuala Lumpur were reviewed. These included 745 fine needle aspirates (FNA's) and 35 nipple smears. The broad categories of cytodiagnoses were as follows: malignant: 95, suspicious or equivocal: 26, benign: 543, no proliferative lesion: 58 and inadequate: 58. The benign and malignant lesions were also subcategorized on cytological basis. The suspicious or equivocal lesions were subjected to biopsy and 17 of these proved to be malignant. 194 cases that were subjected to histological confirmation and 34 cases that were considered to be undisputably malignant (on the basis of clinical features, recurrences, metastases, etc.) were subjected to statistical analysis (total 228 cases). If the cytologically suspicious/equivocal category was considered as "test positive" the sensitivity of cytodiagnosis was 97.4% and the specificity 92%. The high degree of cytodiagnostic sensitivity and specificity make breast cytology a valuable adjunct in the evaluation of breast lesions.

    Over a 32-month period at the University Hospital, Kuala Lumpur, we were able to study the cytological appearance of metastatic nasopharyngeal carcinoma (NPC) in 17 cases. This comprised 14 males and three females of which 13 were Chinese, three were Malay, and one was Indian. Their ages ranged from 27 to 64 years. Histological correlation was available in all the patients in the form of nasopharyngeal biopsies, and they were classified as per the World Health Organization classification into types I, II, and III NPC. Smears from type II NPC showed good cellularity with mainly clustered and occasionally dissociated cells, with focal columnar appearance, vesicular nuclei, prominent nucleoli, and variable amounts of cytoplasm. Clusters of malignant cell closely associated with lymphoid cells and dissociation of malignant cells were more characteristic of type III NPC. FNA cytology is now applied extensively to the diagnosis of head and neck tumours and knowledge of the cytomorphology of NPC would greatly aid in pinpointing the primary of this tumour which is notorious for presenting with early nodal metastasis.

    A case is described of ameloblastoma of the mandible presenting with multiple recurrences and subsequent extension to the maxilla with resultant transformation into an aggressive (malignant?) epithelial odontogenic ghost cell tumour. The latter is a rare, biologically virulent entity that affects mainly males, exhibits a preference for the maxilla and is histologically characterized by atypical malignant odontogenic epithelium associated with areas of ghost cell formation and varying amounts of dentinoid.

    The diagnosis of villoglandular adenocarcinoma of cervix on cytological smears is often missed due to the relatively bland cytological features of this tumour. A 45-year-old female with an exophytic cervical growth had three cervical smears reported as unsatisfactory. A cervical biopsy followed by Wertheim's hysterectomy showed a villoglandular adenocarcinoma (VGA) of cervix. Vaginal recurrence of VGA was again missed on the first post-operative vault smear. The second and third vault smears showed characteristic features of VGA that enabled correct identification. Review of some of the smears previously reported as unsatisfactory showed architectural features of VGA in the three dimensional (3-D) fragments that were previously considered to be benign.

    Objective: To gauge surgical outcome in breast cancer patients with particular reference to overall survival and
    recurrence free survival among breast cancer patients in Hospital Sultanah Nora Ismail Batu Pahat, Johor, Malaysia.
    Methods: Patients undergoing ablative breast cancer surgery were identified and clinical records were assessed.
    Inclusion criteria for enrolment were stage I-IV breast malignancy necessitating resection with or without radiotherapy/
    chemotherapy from 2007 to 2013. All individuals had a pre-operative assessment. The post operative assessment period
    ranged from 1 year to 5 years. Survival distributions were analyzed using Kaplan-Meier curves. Results: A total of
    121 patients were included in this study, with an age range of 28-78 years. Some 98% had undergone local excision/
    lumpectomy/ mastectomy with axillary clearance. While 81% of patients underwent chemotherapy, only 69% had
    radiotherapy. Tumours were oestrogen receptor positive in 58% of cases and progesterone receptor positive in 62%.
    Local recurrence was detected in 10%. The mean age at diagnosis was 51.3 + 10.4 years. The overall survival analysis
    was based on 22 deaths among the 121 patients (18.2%). Three-year and five-year survival rates were 87.6% and 78.4%,
    respectively. Analysis of recurrence-free-survival (RFS) was based on 12 events among 121 patients. The Kaplan-Meier
    RFS analysis revealed that in 90% of the patients with recurrence, it occurred within 45 months. The five year RFS
    rate was 84.5%. The median time taken from diagnosis to ablative surgery was 51 days (upper limit of 791 days).
    Only distant metastasis was a significant factor that impacted on both overall survival and recurrence-free survival
    (p<0.001). Conclusion: Overall survival among our breast cancer patients in our facility is comparable to other in
    other tertiary centres in the country. A trend for earlier detection was noted.

    BACKGROUND: To evaluate the treatment outcome and major late complications of all patients with recurrent nasopharyngeal carcinoma (NPC) treated with intracavitary brachytherapy (ICBT) in Hospital Kuala Lumpur.

    MATERIALS AND METHODS: This retrospective study was conducted at the Department of Radiotherapy and Oncology, Hospital Kuala Lumpur, Malaysia. All patients with histologically confirmed recurrent NPC in the absence of distant metastasis treated in the period 1997-2010 were included in this study. These patients were treated with ICBT alone or in combination with external beam radiotherapy (EBRT). Treatment outcomes measured were local recurrence free survival (LRFS), disease free survival (DFS) and overall survival (OS).

    RESULTS: Thirty three patients were eligible for this study. The median age at recurrence was 56 years with a median time to initial local recurrence of 27 months. Majority of patients were staged as rT1-2 (94%) or rN0 (82%). The proportion of patients categorised as stage III-IV at first local recurrence was only 9%. Twenty one patients received a combination of ICBT and external beam radiotherapy while 12 patients were treated with ICBT alone. Median interval of recurrence post re-irradiation was 32 months (range: 4-110 months). The median LRFS, DFS and OS were 30 months, 29 months and 36 months respectively. The 5 year LRFS, DFS and OS were 44.7%, 38.8% and 28.1% respectively. The N stage at recurrence was found to be a significant prognostic factor for LRFS and DFS after multivariate analysis. Major late complications occurred in 34.9% of our patients.

    CONCLUSIONS: Our study shows ICBT was associated with a reasonable long term outcome in salvaging recurrent NPC although major complications remained a significant problem. The N stage at recurrence was a significant prognostic factor for both LRFS and DFS.
