Synchronous and metachronous malignant melanomas arising in a human immunodeficiency virus-positive patient after the commencement of highly active antiretroviral therapy treatment: a case report

Abstract

BackgroundWe present an unusual case of a patient who developed four melanomas within a few months of diagnosis with human immunodeficiency virus and commencement of highly active antiretroviral therapy therapy. The patient had no previous history of melanoma, and previous skin checks were normal.Case presentationA 50-year-old Caucasian male drainlayer with Fitzpatrick type 2 skin presented for a routine skin examination. He had been diagnosed with human immunodeficiency virus 4 months earlier and commenced on highly active antiretroviral therapy therapy. He was found to have three melanomas (melanoma in situ stage) on excision biopsies, and when he presented for wider excisions of these sites a few weeks later, another new melanoma in situ was found. He had no other medical history of note, and no symptoms to report. He is being followed up 3-monthly.ConclusionsThis case of a human immunodeficiency virus-positive person presenting with four cutaneous melanomas—occurring in both synchronous and metachronous fashion within a 4-month period—is being presented both for its uniqueness and also to highlight the increased need for close skin surveillance in human immunodeficiency virus-positive patients.
