A fluffy white traveller: imported Coccidiodes immitis infection in an Australian tourist.

Pulmonary coccidioidomycosis is a rare cause of pulmonary nodules and respiratory infection in travellers to endemic areas. An Australian tourist suffered an acute respiratory illness while on holiday in Mexico. She subsequently developed erythema nodosum and was noted to have a left pulmonary nodule on chest X-ray after return to Australia. The diagnosis of Coccidioides immitis infection was established by histology and culture of the resected lung lesion. The patient made an uneventful recovery and received one month of therapy with ketoconazole. Culture of the fungus took place under controlled Class 3 conditions. An unusual fungal infection in Australia, coccidioidomycosis poses special risks to staff of microbiology laboratories.
