Abstract
Liposarcomas are soft tissue tumors derived from fat cells and are often seen in the lower extremities and the retroperitoneum. Pleomorphic liposarcomas are seen at the age of 50 and above and make up 5-15% of all liposarcomas. Although liposarcomas involving superficial tissues are very rare, they are histopathologically high-stage tumors. We aimed to present our experience of superficial pleomorphic liposarcoma in an adult case.A single case is reported in our study. A 72-year-old female presented to the Kafkas University general surgery department with a painful mass that had suddenly started to grow on the left leg. Physical examination revealed an immobile painful mass 8 cm in size on palpation at the proximal mediolateral left femoral region. Superficial tissue USG revealed a hypoechogenic solid mass 52x81x42 mm in size and located 2.5 mm below the skin with irregular borders, significant edema of the muscular tissue and significant bleeding with a heterogeneous pseudonodular structure. Total mass excision was performed and the pathology result was pleomorphic liposarcoma. No complication occurred after the surgery. The patient was discharged on the post-operative 4th day. PET CT was conducted a year later and no recurrence was found. Pleomorphic liposarcomas are soft tissue tumors that are seen rarely in advanced ages.It is important to remove these rare tumors of soft tissue with wide excision in elderly patients and to monitor them regularly at frequent intervals.
