At two-year-and-a-half interval post-treatment completion, the patient developed right flank pain and frank haematuria.

Cutaneous manifestations of patients with Human Immunodeficiency Virus (HIV) Infection: A retrospective review of a tertiary referral centre with clinicopathological correlation.

Introduction: The majority of patients with Human Immunodeficiency Virus (HIV) will have cutaneous manifestation during their disease course. We report the spectrum of cutaneous manifestations and clinicopathological concordance in the diagnosis of skin diseases in patients with HIV.

Methods: A retrospective review of all cutaneous manifestations of HIV-infected patients with skin biopsy-proven histopathological confirmation, treated in the University of Malaya Medical Centre, from 2016 till 2018, was performed.

Characteristics of skin cancers among adult patients in an urban Malaysian population.

There has been a rising incidence of skin cancers among Asians in recent years. We present a retrospective analysis of 106 skin cancers and analysed the demography, clinical subtypes of skin cancers and surgical techniques used for skin cancer treatment. In our population, skin cancers were most frequently basal cell carcinomas and diagnosed among ethnic Chinese patients.

Esophageal squamous cell carcinomas in a Malaysian cohort show a lack of association with human papillomavirus.

Objective: With an age-standardized incidence rate of 2 per 100 000, esophageal cancer is not common among Malaysians, but they are nevertheless important due to its poor prognosis. The study is to clarify whether the human papillomavirus (HPV) is associated with esophageal cancer in Malaysians as there has been no report to date on this in Malaysians and other South East Asians.

Methods: Altogether 67 esophageal squamous cell carcinomas histologically diagnosed between 1 January 2004 and 31 December 2014 at the Department of Pathology, University of Malaya Medical Center, Malaysia were considered for HPV analysis using two commercially available methods, polymerase chain reaction with flow-through hybridization (21 HPV GenoArray Diagnostic Kit) and multiplex real-time polymerase chain reaction (Anyplex II HPV28 Detection).
