Background. Solitary fibrous tumor of the pleura (SFTP) is an uncommon neoplasm arising from the submesothelial tissue. We report a case of malignant SFTP with initial massive hemothorax. Case. A 57-year-old man who was receiving warfarin for a cerebral embolism visited our hospital with a complaint of cough and dyspnea. He was given a diagnosis of left spontaneous massive hemothorax, and we performed chest drainage. However, he did not improve with conservative treatment, and therefore we performed thoracotomy. A large necrotic tumor which had ruptured was noted in the left lower lobe intraoperatively, and therefore a lobectomy was performed in addition to the removal of the clot. No residual lesion was found macroscopically within the thoracic cavity. A pathological examination revealed the tumor to be a malignant SFTP, which had invaded the lung and caused extensive hemorrhagic necrosis. The tumor recurred locoregionally and grew rapidly over 3 months postoperatively, and the patient died of respiratory and circulatory failure due to tumor compression shortly afterwards. Conclusion. This case was an unusual clinical presentation of a rare pleural tumor. It is very rare that SFTP features initial hemothorax. The prognosis of this type of tumor after removal is usually not poor, but the present case had a fatal outcome due to early postoperative recurrence.
