Purpose: To suggest an accurate diagnosis and treatment of infiltrating intramuscular lipoma by analysis of the clinical, biological, radiological and pathological features.
Materials & Methods: 20 patients who treated at our hospital for infiltrating intramuscular lipoma from 1998. to 2001 were selected for this study. Mean age was 45.8 years old. Four were All cases were checked preoperative radiographs, MRI and diagnosed by biopsy. The methods of surgical treatment included excision of tumor and peripheral tissue. We assessed the recurrence by follow up.
Results: Tumors located in upper limbs 5 cases, lower limbs 3 cases, abdomen 3 cases, gluteal region 1 case. In preoperative radiographs, infiltrating intramuscular type were 7 cases. In 11 cases, tumors were completely excied with peripheral tissue. 1 cases was incompletely excised because it was very huge mass and infiltrated lung . Encapsulated tumors were 3cases and uncapsulated tumors 9 cases. There were no recurrence excepts 1 case that was infiltrated lung.
Conculsion: Infiltrating intramuscular lipoma was wrongly diagnosed as well differentiated liposarcoma. To increase the rate of correct diagnosis, preoperative radiographs, MRI and pathologic diagnosis were performed. Careful wide excision is necessary to prevent the recurrence.
