Myxoid liposarcoma

Summary Liposarcoma is an important soft tissue sarcoma. It requires careful classification into types, since prognosis varies considerably with histological appearance. In this case a myxoid sarcoma is shown to contain cells resembling fetal fat with active pinocytosis, and some scanty signet-ring cells. Their ultrastructural appearances are described.The author is indebted to Priv.- Doz. Dr. K. Donath, Department of Pathology University Hamburg, for electron microscopic photographs
