Multicentric Myxoid Liposarcoma; a Case Report and Literature Review

Abstract

<br/><span style="font-size: xx-small;">Liposarcoma is a common malignant soft tissue tumor, accounting for 10% to 16% of all sarcomas. Multicentric myxoid liposarcoma is an uncommon condition. Differentiation between several primary tumors and metastasis of a single </span><span style="font-size: xx-small; font-family: Arial,Arial;"><span style="font-size: xx-small; font-family: Arial,Arial;">liposarcoma represents the main difficulty in diagnosis. A 47-years old woman presented with right thigh myxoid liposarcoma and underwent wide margin tumor resection. Other investigations like CXR, abdominal and pelvic CT-scans were negative. After 18 months another myxoid liposarma was found in her ipsi-lateral breast without any evidence of </span></span><span style="font-size: xx-small;">other organs metastasis.</span> <br/>Second lesion location, time between two presentation and cytogenetic differences are accepted criteria to site a sarcoma in multicentric category, but in myxoid liposarcoma these can be explained by the special features inherent to this tumor. <br/>
