Solitary Fibrous Tumor of the Pleura With Abdominal Aortic Blood Supply.

A solitary fibrous tumor of the pleura (SFTP) presenting with an aberrant arterial supply from the abdominal aorta is extremely rare, and it may be difficult to distinguish from intralobar sequestration (ILS). We report the case of a 38-year-old woman who presented with acute chest pain and was subsequently found to have a 17.5-cm intrathoracic mass. After preoperative arterial embolization of its feeding vessel, this presumed ILS was resected. However, the intraoperative findings revealed a benign SFTP. Here we discuss a unique presentation of a large SFTP radiographically mimicking an ILS, and we propose a safe management strategy for this entity.

Solitary fibrous tumor of the pleura: morphogenesis and progression. A report of 36 cases.

PURPOSE: We attempted to identify the exact point of tumor eruption of a solitary fibrous tumor of the pleura (SFTP). METHODS: We morphologically classified 36 SFTPs into 5 categories. Type A showed a connection that included a bloodstream with the pleura on both sides. Type B only showed a connection that included a bloodstream with the visceral pleura, and had a non-bloodstream connection with the parietal pleura. Type C only showed a connection that included a bloodstream with the visceral pleura, and had no connection with the parietal pleura. Type D showed a non-bloodstream connection with the visceral pleura, and only showed a connection that included a bloodstream with the parietal pleura. Finally, type E had no connection with the visceral pleura, and only showed a connection that included a bloodstream with the parietal pleura. The clinicopathological profiles of the tumors were investigated according to their type. RESULTS: The distribution of the 36 SFTPs was as follows: A (19 %), B (6 %), C (67 %), D (0 %) and E (8 %). The tumors categorized as type A tended to be large in size. CONCLUSIONS: SFTPs commonly arise from the visceral pleura and in accordance with tumor progression they will form a non-bloodstream connection with the parietal pleura. Finally, a vascular pedicle will arise with the parietal pleura.

Computed tomography manifestations of a malignant solitary fibrous tumour of the pleura with distinct blood supply from celiac trunk.

Solitary fibrous tumours of the pleura (SFTPs) are rare and roughly 80% of them have a benign course. Malignant SFTPs are seldom reported, as are their computed tomography (CT) manifestations. We report the case of a 45-year old male patient who presented with coughing for over 2 months. A large lesion in his right hemithorax was found by chest X-ray. CT scan showed patchy areas and a sharp time-attenuation curve. CT angiography reconstruction revealed a distinct feeding vessel from celiac trunk. After surgery, the tumour was confirmed to be a malignant SFTP by immunochemistry.

Solitary fibrous tumor of the pleura with a minute malignant component and diaphragmatic vascular supply: report of a case.

We resected a fist-sized, solitary fibrous tumor of the pleura (SFTP) with a minute malignant component, following percutaneous embolization of its feeding artery. The tumor had macroscopic characteristics of a benign SFTP, and most parts of it were microscopically benign. However, further careful pathological examination revealed a minute malignant component in its periphery. We report this case to show that large and mostly benign SFTPs may contain malignant components, which can be overlooked. Thus, large SFTPs should be resected in consideration of this possibility.
