Cryptococcosis presenting as upper limb cellulitis and ulceration: a case series.

We report four cases of cryptococcosis presenting as upper limb cellulitis or ulceration, or both. Three of the four patients were on long-term prednisolone therapy at the time of presentation. In each case, the diagnosis of cryptococcosis was established by a biopsy of the skin. Only one of the four patients had conclusive evidence of disseminated disease. Our cases highlight the importance of skin biopsy in immunosuppressed individuals presenting with cellulitis, particularly when the cellulitis occurs in an atypical location and when the clinical condition fails to respond to standard antibacterial therapy.
