Primary Leiomyoma of the Pleura

Case Reports

Primary Leiomyoma of the Pleura

Xiaoming Qiu et al. World J Surg Oncol.


Primary leiomyoma of the pleura is extremely rare. A 45-year-old man presented with a complaint of right chest pain. Chest computed tomography demonstrated a solid, round pleural mass in the right anterior chest wall. The mass was completely resected, and histopathological examination revealed a localized primary pleural leiomyoma. The patient was followed and has been disease-free for over 15 months. This is the first report of primary leiomyoma of the pleura in China. A review of the literature on primary leiomyoma of the pleura is presented.

Chest images (A) Chest radiograph. A mass is seen in the right middle lung field on chest roentgenogram; (B) Chest contrast enhanced computed tomography scans. A solid, round pleural mass is seen in the right anterior chest wall, with heterogeneous density and calcification. It is well capsulated and compresses the lung parenchyma without any sign of infiltration of lung or chest wall.

Hematoxylin-and-eosin staining reveals a proliferation of interlaced fascicles of spindle cells showing moderate atypia and less than 1/50 mitotic figures per high power field. Immunohistochemical staining reveals diffuse and strongly positive reactions with both anti-SMA and -desmin antibodies.
