title: [Hyaline vascula type Castleman's disease in the pelvic cavity : a case report].
abstract: A 48-year-old man was admitted to our hospital in order to treat a right lower abdominal tumor which was detected by ultrasonography in a general health check. The tumor was considered to be a pelvic sarcoma from computed tomography and magnetic resonance imaging findings, then, resection of the tumor was performed. Pathological diagnosis was a hyaline vascular type of Castleman's disease. The patient remained well without any evidence of local recurrence 12 months after surgery. The hyaline vascular type of Castleman' s disease is characterized by a solitary hypervascular tumor which is prone to adhere to neighboring great vessels. This tendency makes dissection from great vessels difficult and should be kept in mind when surgery is planned.
