[A Case of Anaplastic Carcinoma with Osteoclastlike Giant Cells of the Pancreas Concomitant with Lung Recurrence of Solitary Fibrous Tumor].

ABSTRACT

A 32-year-old woman presented with epigastric pain and an abdominal mass. Abdominal CT showed a 130mm pancreatic tail mass with an enhanced rim, central necrosis, and small calcification. A 6mm lung tumor was also found via chest CT. Her medical history included surgical resection of cerebral solitary fibrous tumor when she was 24 years old. When she was 31 years old, it had recurred but was cured by gamma knife radiosurgery. We performed distal pancreatectomy and splenectomy with lymph node dissection. According to pathological and immunohistochemical findings, it was diagnosed as an anaplastic carcinoma with osteoclast-like giant cells. She underwent surgical resection of the lung tumor 2 months after pancreatic resection and was diagnosed with metastasis from the solitary fibrous tumor. Fourteen months since undergoing pancreatectomy, the patient experienced no recurrence from both diseases. We report a rare resected case of anaplastic carcinoma of pancreas concomitant with recurrent solitary fibrous tumor.
