The authors present a case - history of massive localized lymphedema in a 54 year old female patient (height 167 cm, weight 113 kg). The history of the lymphedema lasted about 1 year. Its growth was not accompained with subjective complaints. It was diagnosed as a pendulous tumor of soft tissues in the thigh, 70 x 65 cm large. In preoperative diagnosis it was classified as a liposarcoma. The tumor lesion was removed and sent for bioptic examinations. Both histological and immunohistochemical biopsies denied benign or malignant nature of the soft tissue tumors and confirmed the diagnosis of a massive localized lymphedema.

        Key words: lymphedema - liposarcoma - obesity - reactive lesions
