Primary cryptococcal cellulitis caused by Cryptococcus neoformans var. gattii in an immunocompetent host.
Primary cutaneous cryptococcal infection is uncommon. The cutaneous manifestations are most often the result of dissemination from the central nervous system or lung, usually in an immunocompromised host; cellulitis is regarded as the rarest cutaneous form. Primary cutaneous cryptococcosis has occasionally been reported in the immunocompetent, the causative organism being Cryptococcus neoformans var. neoformans. We present a case of cellulitis of the right arm in a 75-year-old man caused by Cryptococcus neoformans var. gattii, a fungus which is endemic in Australia and an important cause of infection in the immunocompetent. This is the first case described of a primary cutaneous infection due to Cryptococcus neoformans var. gattii. The interesting ecology of this organism is discussed.
