[Cutaneopulmonary blastomycosis]. / Blastomycose cutaneo-pulmonaire.

We observed a new case of blastomycosis in a patient with haemoptysis. The chest X-ray revealed a lesion confined to the upper right lobe of the lung and there was an ulcerating vegetation at the medial angle of the right eye. Skin biopsy and bronchial aspiration led to the identification of typical Blastomyces dermatitidis. Outcome was favourable after oral therapy with ketoconazole. Cutaneo-pulmonary blastomycosis is weakly endemic in Tunisia. Pulmonary lesions are more frequent because of airborne transmission. Cutaneous lesions may be clinically misleading. This disease is sensitive to antifungal imidazole derivatives.
