She has had a subcutaneous mass in the left buttock for about 10 years and received operations twice for the lipoma at a previous hospital, but she had repeated recurrence of the tumor. Clinical findings showed a subcutaneous mass about 21cm in the left buttock. CT examination showed a lipoma-like shadow with septums. Pathological findings showed the tumor was composed of mature adipose tissue and contained atypical cells within dense fibrous bands. We diagnosed this tumor as lipoma-like liposarcoma. The recurrence of the tumor was found by MRI examination 2 years and 8 months after the operation. We performed wide local excision with a margin of surrounding normal muscle for the recurrent tumor. There have been no recurrences and distance metastases of the tumor for 8 months.The characteristic of the lipoma-like liposarcoma, shown by CT and MRI scans, a giant lipoma-like tumor with dense fibrous structures, present among the muscles of the limbs. Because of the marked tendency of local recurrence of the tumor, we carefully discussed the condition and decided that the tumor margin should be excised. After the operation, no recurrence has been seen for 8 months. [Skin Cancer (Japan)2002; 17: 65-69]Read More
