title: [A case of metachronous, multifocal development of liposarcoma in the back of left thigh, the left subclavicular region and the right perirenal tissue].
abstract: A 46-year-old woman had received surgery to remove a mass arising from the back of the left thigh 13 years before and on the left subclavicular region 3 years before. Histological diagnosis of both masses was myxoid type liposarcoma. She was admitted to our hospital because of right abdominal pain. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) revealed the presence of a large retroperitoneal tumor. The removed specimen weighed 1,450 g and measured 24 x 13 x 9 cm in size. Histological diagnosis was myxoid type liposarcoma. She has been free of any recurrence for 4 months postoperatively without adjuvant therapy.
