Isolated crater-like tumour in a renal transplant recipient

Compared with asymptomatic pulmonary cryptococcosis, secondary cutaneous cryptococcosis may be the first clinical manifestation of disseminated infection but it can be difficult to diagnose clinically. The clinical manifestation of cutaneous cryptococcosis is not pathognomonic, varying from nodules to ulcers and plaques, and frequently mimics other pathologies. This case highlights that an isolated tumour can be an initial manifestation of systemic cryptococcosis in a kidney transplant patient.
