A Case of Myxoid Liposarcoma / 대한피부과학회지

ABSTRACT

Liposarcomas are one of the most common soft-tissue sarcomas in adults. They usually arise in the deep soft tissues, and patients present with large painless masses. Four major types of liposarcomas are generally recognized and have epidemiologic and prognostic differences atypical lipomatous neoplasm/well-differentiated; myxoid/round- cell; dedifferentiated; pleomorphic variants. Myxoid liposarcoma is the second most common type of liposarcoma, representing 30~40% of all liposarcomas in the extremities. We report a case of myxoid liposarcoma in a 78-year-old man who presented with an asymptomatic, firm, deep-seated mass in the lateral aspect of his left upper arm.
