Abstract
Tracheal or bronchial leiomyoma is an extremery rare disease, the numbers of reported cases are gradually increasing as a result of increasing numbers of bronchofiberscopic examination. In all of the reported cases in the Japanese literature, the tumors occurred in bronchi proximal to segmental bronchus. We found a leiomyoma originating from a subsegmental bronchus by endoscopic examination in a patient with obstructive pneumonia. The patient was a 29-year-old woman, who suffered from acute pneumonia in the region of right S^3 twice in a period of nine months being cured by treatment with ofloxacin each time. We suspected the prescence of a bronchial lesion which might be the cause of pneumonia and performed endoscopic examination The patient was diagnosed as having a leiomyoma in right B^3_b which was successfully treated by endoscopic snaring and Nd-YAG laser therapy, resulting in complete cure.
