Primary cutaneous cryptococcal cellulitis secondary to insect bite in an immunosupressed patient after liver...

Cutaneous cryptococcosis is usually a manifestation of disseminated disease, especially in immunosuppressed patients. Primary cutaneous cryptococcosis has also been described in some patients without evidence of systemic disease. Distinguishing between primary and secondary cutaneous cryptococcosis may be difficult as patients can be asymptomatic or cutaneous lesions may precede systemic involvement by some months. Features supporting primary disease are a history of cutaneous inoculation, and solitary superficial lesions on uncovered parts of the body. We present a liver transplant patient with cutaneous cryptococcal cellulitis subsequent to an insect bite, without systemic involvement and with excellent response to treatment with amphotericin B for 15 days and surgical debridement plus oral fluconazole for 3 months. In immunosupressed patients with cellulitis a cryptococcal infection must be excluded. If cutaneous cryptococcosis is diagnosed, systemic evaluation and prompt lengthy treatment are required.
