A Case of Sclerosing Hemangioma Forming a Pedunculated Mass

We report our experience with an unusual case of sclerosing hemangioma (SH) that formed a pedunculated mass protruding into the thoracic cavity. A pulmonary tumor was found in a 60-year-old female during the medical examination. Computed tomography showed a 19 × 17-mm nodule with a clear border and smooth margin contiguous with the diaphragm in the right S8 segment. Uneven enhancement following contrast medium administration was observed. We performed a 3-port thoracoscopic wedge resection of the right lower lobe. We observed a yellow pedunculated tumor protruding from the diaphragmatic surface of the right lower lobe. The surface of the tumor was smooth and encapsulated. Microscopically, we diagnosed it as a SH. SHs usually exist adjacent to the visceral pleura, but rarely form pedunculated tumors protruding into the cavity as seen in this case. By thoracoscopic surgery, we successfully diagnosed and treated the patient in a minimally invasive manner. Since there have been reported cases of recurrence, we anticipate that periodic follow-up observations will be required.
