Abstract:
Objective To report a case of disseminated cryptococcosis with cutaneous manifestations and osteomyelitis. Methods and Results A 33 year old female was admitted due to multiple nodules and ulcers on the upper arms, shoulders, buttocks and thighs for one year. The patient was pregnant when admitted, and gave birth to a premature baby during her illness. The nodules increased half a month after delivery, which was suspected to be hematogenously disseminated pulmonary tuberculosis and was given anti tuberculous therapy for three months but failed. Physical examination showed there were 39 nodules or ulcers on the face, gum, trunk, buttocks and extre mities. The bone structure of the left tibia and fibula destroyed and a sinus developed on the left fibula. Microbiologic examination showed that lots of spores were seen in the smear of pus and necrotic tissues, which produced yeast like colonies in culture with positive urease and caffeic acid test. Cryptococcus neoformans, serotype A was identified by API yeast reaction band and serology. Inoculation with mice and rats showed that their brains, lungs and livers were involved easily. Further identification as C.neoformans var.neoformans was obtained based on sequence analysis of ribosomal internal transcribed spacer region 2. The anti tuberculous therapy was stopped and anti fungal therapy was initiated at once. Intravenous and topical amphotericin B in combination with fluconazole were chosen in the initial therapy and itraconazole for maintenance. The nodules disappeared after 30 days and the last ulcer in the left tibia healed completely after 200 days. The anti fungal therapy was discontinued after 277 days and the patient was completely cured.
