Case Report: Nummular dermatitis mimicking extensive Tinea corporis or Sulzberger-Garbe dermatosis in an HIV patient

Abstract

Annular lesions in dermatology vary and include tinea corporis, discoid lupus, granuloma annulare,
psoriasis, nummular dermatitis and Sulzberger-Garbe dermatosis. These lesions are mostly multiple, scaly
and “coin-shaped” differing from each other based on other clinical features and laboratory investigations.
We present a case of large annular patches in a 40 year old male whose lesions demonstrated changing
features with clinic attendance. He was initially assessed to have tinea corporis but subsequent clinic
attendance and laboratory investigations led to a diagnosis of nummular dermatitis and a consideration of
Sulzberger-Garbe dermatosis.
