A case of blastomycosis from Zaria, Nigeria

Abstract
A case of blastomycosis from Zaria, Nigeria is reported. The clinical features were indistinguishable from those of tuberculosis which is very common in this environment. Lack of response to anti-tuberculosis therapy within eight weeks prompted the search for other organisms which resulted in the isolation of Blastomyces dermatitidis. Compatible histological evidence was obtained. Subsequent favourable response to amphotericin B was evident. Infection with this organism should be included in the differential diagnosis of pulmonary and pleural lesions simulating tuberculosis in West Africa.
