Solitary fibrous tumor of the pleura. Analysis about 41 cases Solitary fibrous tumor of the pleura (TFSP) is an uncommon and mostly benign neoplasm. It grows slowly and presents with scant symptoms. Recurrence after surgical excision has been described. The aim of this report is to show our experience in managing this disease. Clinical as well as radiological, surgical, histopathological and follow-up data were analyzed in a clinical series. Forty one cases of TFSP that underwent surgery at our institution between 1991 and 2004 were retrospectively analyzed; 27 were females and 14 males with a median age of 60.4 years old; 24.4% of the cases were asymptomatic. All tumors were surgically excised, in average they weighed 945 g and 36.5% of the lesions showed a pedicle. Most of the lesions were originated in the visceral pleura. Surgical morbidity was 12.1% and no mortality was recorded. Three tumor recurred. TFSP is usually a benign neoplasm but it can recur. Complete surgical excision is the treatment of choice of primary and recurrent tumors.
