BACKGROUND: The Gut and Obesity in Asia (GOASIA) Workgroup was formed to study obesity and gastrointestinal diseases in the Asia Pacific region. We aimed to 1) compare the characteristics of elderly (i.e. age ≥ 60) vs. non-elderly patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD); 2) identify predictors of advanced fibrosis in elderly patients with NAFLD; and 3) assess the performance of non-invasive fibrosis scores in the prediction of advance fibrosis in the elderly population.

METHODS: We abstracted the data of 1008 patients with NAFLD from nine centers across eight countries. Characteristics of elderly and non-elderly patients with NAFLD were compared using 1:3 sex-matched analysis.

RESULTS: Of the 1008 patients, 175 were elderly [age 64 (62-67) years], who were matched with 525 non-elderly patients [46 (36-54) years]. Elderly patients were more likely to have advanced fibrosis (35.4% vs. 13.3%; p

Marjolin's Ulcer in Laron Syndrome - an Unexpected Combination: A Case Report

de la Paz EM

Malays Orthop J, 2020 Mar;14(1):78-80.

PMID: 32296486 DOI: 10.5704/MOJ.2003.012

Marjolin's ulcer is an atypical malignancy that develops from deep scars of chronically traumatised skin. Laron syndrome (LS) is a rare autosomal recessive growth retardation from a mutation in the growth hormone receptor (GHR) gene leading to defective GHR, growth hormone insensitivity and eventual low levels of insulin-like growth factor type 1 (IGF-1). Affected individuals present with proportionate dwarfism and other characteristic physical defects, but at the same time are conferred protection against cancer due to low serum levels of IGF-1. We report an exceptional case of Marjolin's ulcer in the foot of a female LS patient 30 years after she sustained flame burns as a 6-month-old baby. Three months before coming to us, she had a 2x3cm ulcer that turned into a rapidly enlarging fungating mass involving the leg, ankle, and foot. Histopathologic analysis of an incision biopsy showed well-differentiated squamous cell carcinoma. The extent of her lesion precluded wide excision. Below knee amputation was done. A second biopsy confirmed the histopathologic diagnosis. This is the first reported case in the literature of Marjolin's ulcer in LS which raises the possibility that IGF-1 deficiency does not completely protect against squamous cell cancer.

Fulltext Ulcerative colitis in Malaysians

Jayalakshmi P, Wong NW, Malik AK, Goh KL

JUMMEC, 1996;1(2):39-42.

A review of all colonic biopsies received by the Department of Pathology during a 8-year period revealed 41 cases of ulcerative colitis (UC). The diagnosis was based on histological and clinical features. The age range of patients was between 14 - 76 years with a median age of 35.4 years. The disease was more prevalent among Indians. The common presenting sysmptoms were diarrhoea (100%) and haematochezia (83%). The extent of colonic involvement varied. Twelve patients (29.2%) had pancolitis and 8 (19.5%) had proctitis.Extraintestinal manifestations were rare and only one patient had pyoderma gangrenosum. One patient developed multifocal colorectal cancer 10 years after the inial diagnosis of UC and died 2 years later due to metastases. Histology plays an important role in the diagnosis and management of patients with UC. We noted a good correlation between clinical and pathological features. The most recent colonic biopsy showed features of chronic UC with activity in 34 cases and features of remission in 4 cases.

Cytohistology of morule in cribriform-morular variant of papillary thyroid carcinoma

Sakurai K, Onouchi T, Yamada S, Baba Y, Murata T, Tsukamoto T, et al.

Malays J Pathol, 2019 Dec;41(3):339-343.

PMID: 31901919

INTRODUCTION: Cribriform-morular variant (CMV) is a rare variant of papillary thyroid carcinoma. It frequently occurs in association with familial adenomatous polyposis (FAP), although some cases are sporadic. Herein, we report a case of CMV and analyse morule cytohistology.

CASE REPORT: The patient was a 47-year-old woman with no familial history of FAP. A 3.0-cm unifocal mass was identified in the left thyroidal lobe. Fine-needle aspiration cytology revealed papillary clusters of atypical cells with nuclear grooves, which was suspected to be conventional papillary thyroid carcinoma. Histologically, the tumour comprised a papillary and cribriform growth of atypical cells with cytoplasmic accumulation and nuclear translocation of b-catenin. In addition, frequent morule formation was identified.

DISCUSSION: In this case, we performed morule analysis through correlative light and electron microscopy (CLEM), and revealed its ultrastructure. Although CMV is a rare form of thyroid carcinoma, it should be considered along with its distinct clinicopathological characteristics.

Chronic granulomatous mastitis with axillary lymphadenopathy in a nulliparous woman

Rajendran D, Chew BS, Wong MW, Cheong YT

Med J Malaysia, 2019 12;74(6):564-565.

PMID: 31929493

Chronic Granulomatous Mastitis (CGM) is a rare disorder and this generally occurs in young women with a recent history of lactation. Development of this disease in nulliparous women are rare with an incidence of 10%. Axillary lymphadenopathy is seen in 15% of cases diagnosed with CGM. We present a case of CGM in a 23- year-old nulliparous woman presenting with a breast mass and multiple axillary lymphadenopathy. To the best of our knowledge there are no documented cases of both these rare clinical features occurring simultaneously. The use of oral steroids prevented surgery and effectively induced remission.

Allele HLA-DQB1*06 reduces fibrosis score in patients with non-alcoholic fatty liver disease

Tan HL, Zain SM, Eng HS, Mohamed Z, Mahadeva S, Chan WK, et al.

Hepatology research : the official journal of the Japan Society of Hepatology, 2020 May 14.

PMID: 32410320 DOI: 10.1111/hepr.13525

AIM: Human leukocyte antigen (HLA) regions were highlighted as important genetic markers for various liver diseases by hepatology-related genome-wide association studies. Replication studies in non-alcoholic fatty liver disease (NAFLD) are limited and none has investigated the association of HLA alleles with non-alcoholic steatohepatitis (NASH) and other histological characteristics. In the current study, we examined the association of HLA-DQA1 and HLA-DQB1 alleles with NAFLD spectrum and its histological characteristics.

METHODS: Consecutive biopsy-proven NAFLD patients (n = 191) and healthy controls (n = 188) were enrolled and genotyped for HLA-DQA1 and HLA-DQB1 alleles using the sequence-specific oligonucleotide-polymerase chain reaction method.

RESULTS: No association was found between the HLA alleles and NAFLD or NASH in a case-control setting. Nevertheless, among NAFLD patients, the frequency of HLA-DQB1*06 allele was significantly the lowest in NASH with significant fibrosis (10.4%) and approximately similar for NASH without significant fibrosis (22.9%) and NAFL (22.5%) (P = 0.004). It is noteworthy that the association remains significant after correction for multiple comparisons (Pc = 0.04). Multivariate analysis revealed that HLA-DQB1*06 allele is also associated with fibrosis score (P = 0.001); the result remains significant after correction for multiple comparisons.

CONCLUSION: These findings suggest that HLA-DQB1*06 is associated with lower fibrosis score in NAFLD patients.

Fulltext Usefulness of a scoring system in the interpretation of histology in neonatal cholestasis

Lee WS, Looi LM

World J Gastroenterol, 2009 Nov 14;15(42):5326-33.

PMID: 19908342 DOI: 10.3748/wjg.15.5326

AIM: To ascertain the usefulness of a histological scoring system devised to assist in the interpretation of liver histology in neonatal cholestasis (NC).

METHODS: Liver biopsy specimens obtained from infants with NC referred to a tertiary pediatric unit in Malaysia were prospectively studied. The first author, blinded to the final diagnosis, devised the histological diagnosis based on a 7-feature (portal ductal proliferation, bile plugs in portal ductules, porto-portal bridging, lymphocytic infiltration in portal region, multinucleated hepatocytes, neutrophilic infiltration, hepatocellular swelling), 15-point (0 to 15) scoring system. The author classified the histological diagnosis as either biliary atresia (BA) or neonatal hepatitis (NH, all other diagnoses), and subsequently compared the author's diagnosis with the final diagnosis.

RESULTS: Eighty-four biopsy specimens obtained from 78 patients were reviewed. Without the scoring system, BA was correctly diagnosed by the author histologically in 30 cases, labelled as NH in 3. For other diagnoses, BA was excluded correctly in 33 cases and mislabeled as BA in 2 cases. The overall sensitivity for BA was 91%, specificity 86% and accuracy 88%. With the scoring system, a score of >or=7 had the best diagnostic utility to differentiate BA from other intrahepatic cholestasis histologically (sensitivity 88%, specificity 94%, accuracy 92%). Four patients with a score<7 had BA, and 3 patients with a score>or=7 had NH.

CONCLUSION: A 7-feature, 15-point histological scoring system had good diagnostic accuracy in the interpretation of liver histology in neonatal cholestasis.

Fine-needle aspiration cytology of metastatic nasopharyngeal carcinoma

Jayaram G, Swain M, Khanijow V, Jalaludin MA

Diagn Cytopathol, 1998 Sep;19(3):168-72.

PMID: 9740988 DOI: 10.1002/(sici)1097-0339(199809)19:3<168::aid-dc2>3

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.

Orbital multiple myeloma: a diagnostic challenge

Tai E, Sim SK, Haron J, Wan Hitam WH

BMJ Case Rep, 2017 Aug 07;2017.

PMID: 28790098 DOI: 10.1136/bcr-2017-220895

Orbital involvement in multiple myeloma is unusual. We describe the case of an 85-year-old woman who presented with right eye proptosis, reduced visual acuity and diplopia. Computed tomography showed a lobulated, enhancing soft tissue mass arising from the right greater wing of the sphenoid with intraconal, lacrimal gland and ocular muscle involvement. Histopathology revealed predominantly atypical plasma cells in a background of reactive lymphocytes, with monoclonality towards kappa light chain protein, suggestive of multiple myeloma. This case illustrates the diagnostic imaging challenge of orbital multiple myeloma.

Malays Orthop J, 2017 Nov;11(3):50-52.

PMID: 29326768 MyJurnal DOI: 10.5704/MOJ.1711.004

Streptococcus constellatus is an extremely rare cause of pyogenic spondylodiscitis. Literature search yielded only one case report in an elderly 72 years old man with spontaneous T10-T11 S. constellatus spondylodiscitis. It is virtually unheard of in young teenage. We report the case of a 14 years old male teenager who presented with worsening low back pain for one year with no neurological deficit. Imaging studies were consistent with features of L4-L5 spondylodiscitis. CT guided biopsy grew a pure culture of streptococcus constellatus sensitive to penicillin and erythromycin. He showed full recovery with six weeks of intravenous antibiotics. Due to the insidious onset, this case highlight the importance of high clinical suspicion and early diagnosis, with image guided biopsy followed by treatment with appropriate intravenous antibiotics to enable full recovery without further neurological deterioration.

GMS Ophthalmol Cases, 2017;7:Doc04.

PMID: 28194321 DOI: 10.3205/oc000055

Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis.

BMJ Case Rep, 2020 Nov 30;13(11).

PMID: 33257363 DOI: 10.1136/bcr-2020-236204

Head and neck synovial sarcoma is rare. We report the case of a 71-year-old man who presented with progressive dysphagia, odynophagia, shortness of breath on exertion and hoarseness of voice. Nasendoscopy revealed a smooth, non-fungating, non-ulcerative mass arising from the left lateral pharyngeal wall. CT showed a well-defined, heterogenous enhancing lesion arising from the left pyriform fossa. Initial biopsy taken was inconclusive and patient underwent a transcervical complete excision of the tumour, where histopathological analysis confirmed the diagnosis of monophasic synovial sarcoma of the left pyriform fossa. This patient also received adjuvant radiotherapy postoperatively and remained disease free 1 year after completion of treatment.
