Abstract
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.
Highlights
Leiomyomas are benign smooth muscle tumors that are commonly encountered in the urogenital tract, occasionally in the gastrointestinal tract, and rarely in the respiratory tract [1]
Computed tomography showed a solid, round pleural mass measuring 5.9 cm × 8 cm × 6.2 cm located in the right anterior chest wall, with “ heterogeneous density and calcification
Leiomyomas commonly originating from urogenital tract and gastrointestinal tract are most benign smooth muscle tumors, and rarely originates from respiratory tract and pleura
Summary
Leiomyomas are benign smooth muscle tumors that are commonly encountered in the urogenital tract, occasionally in the gastrointestinal tract, and rarely in the respiratory tract [1]. A mass was seen in the right middle lung field on chest roentgenogram (Figure 1A). Computed tomography showed a solid, round pleural mass measuring 5.9 cm × 8 cm × 6.2 cm located in the right anterior chest wall, with “ heterogeneous density and calcification. It was well capsulated and compressed the lung parenchyma without any sign of infiltration of the lung or chest wall (Figure 1B). A giant, well-capsulated smooth-surfaced tumor was observed in the anterior chest wall. It was resected en-bloc with surrounding tissue. Since the malignant potential of the tumor could not be determined, close follow-up of the patient was advised
