Sporothrix infection of the lung without cutaneous disease. Primary pulmonary sporotrichosis.

The clinical spectrum of sporotrichosis is expanding and now includes pulmonary infection in absence of skin lesions. Lung involvement, albeit unusual, is a granulomatous pneumonitis which may progress to bilateral, apical, fibrotic, and contracted infiltrates or cavities, thereby mimicking tuberculosis or histoplasmosis. The patients are most often middle-aged men with alcoholism and chronic obstructive pulmonary disease. Our case report is yet another variant of primary pulmonary sporotrichosis that presented as diffuse, bilateral granulomatous pneumonitis without cavitation or predilection for upper lobes.
