Primary cutaneous cryptococcosis in an HIV-negative patient.

We report a case of primary cutaneous cryptococcosis in an HIV-negative patient, who presented with painless, ulcerated lesions involving the right forearm (fingers and elbow), which developed over 45 days. On the basis of the clinical appearance, serological and cultural examinations were performed to confirm the diagnosis; the histological evaluation of a skin biopsy showed an acute inflammatory infiltrate containing several PAS + Cryptococci. Subsequently, the patient was treated with fluconazole (400 mg/day for 10 days, then a maintenance therapy of 200 mg/day); after one month, the cutaneous lesions were remarkably improved, but, although a series of further laboratory and clinical examinations was scheduled, the patient repeatedly refused any other re-evaluation, and he was lost from follow-up.
