Fibrous lung tumor: a peculiar case.

Solitary fibrous tumor (SFT) of the pleura and the lung is an uncommon spindle cell neoplasm arising from the visceral pleura in the majority of the cases. However there are some extrapleural sites including the lung. Current considerations were raised by a peculiar recent case: an 81-year-old female, no smoker, presented with undefined left thoracic pain. Radiographic findings of a large solid lung mass (10 cm × 9 cm). Computed tomography (CT) confirmed the thoracic mass showing characteristics of a well defined mass with capsule, the position of the mass in proximity of the postero-basal and lateral-basal wall. No secondary lesions were found. Through a left inferior lobectomy and ilo-mediastinal lymph node sampling, the entire mass was resected. Histopathological examination revealed a SFT. In conclusion STF is a rare lesion and this case showed a peculiar extremely large lesion never described before in literature.
