SUMMARY
Attention is drawn to the not uncommon condition of pulmonary mycetoma (asper‐gilloma). From a personal series of seven cases, two histories are quoted, one being a patient with bilateral lesions.
Some aspects of the aetiology of the primary lesion and of the mycological features are discussed, and reasons advanced in explanation of an apparent increase in incidence.
The radiographic features are described, with reference to differential diagnosis, and tomography is recommended as the most valuable procedure in case of doubt.
Once recognized, it is suggested that active intervention is rarely necessary and often unwise.
