Monosporium apiosperum (M. ap.) causes most commonly the lesion of skin and subcutaneous tissues of the foot and become clinically one of the causes of madura foot. Primary infection of this fungus in lung is extremely rare. Two cases of pulmonary Monosporiosis were found in the resected lungs postoperatively. The first case was reported in Japan J. Med. Mycol. in 1966 by the authors and Uetsuka and the second was found in 1972.
The first case was a 31-year-old farmer's housewife with complaints of frequent cough, spu tum and rapid onset of pulmonary symptoms. Progressive inflammation and marked saccular bronchiectasis with disseminated granules of M. ap. were observed from the distal end to the proximal portion of B5 in the resected left lung.
The second case was a 49-year-old single female with complaints of occasional bloody expectoration for the past 2 decades. The chest radiogram had revealed almost unchanged fungus ball 2.0cm in diameter in a cavity. Bronchiectatic cavity containing fungus ball of M. ap. was found in distal branch of B2a of the resected right upper lobe.
Histological findings of the cases were similar to those of aspergillosis. For the detection of M. ap. from the foci, egg-media was more excellent than Sabouraud's agar media.
