[well-differentiated liposarcoma]

Liposarcoma is the most common soft tissue malignant tumor . It mostly arises in the subcutaneous tissue of shoulders , limbs and neck , and retroperitoneal space , but head occurrence is very rare . Atypical lipomatous tumor (ALT ) is a well-differentiated liposarcoma (WDLPS ) and constitutes 40 -45 % of all liposarcoma cases . A case of 57 -year -old woman with a tumor of the left cheek , causing a discreet face asymmetry is presented . The tumor was soft and caused no tenderness . The patient reported no previous injury of the region . Fine-needle aspiration biopsy (FNAB ) revealed atypical cells suspected of liposarcoma . MR examination showed fascicles of adipose tissue , which made the left cheek prominent . The patient was operated under general anaesthesia . Adipose tissue of the left cheek was removed . Postoperative course was uneventful . The final histopathological diagnosis - was atypical lipomatous tumor /well-differentiated liposarcoma (ALT /WDLPS ). The patient remains under laryngological care . No recurrence of the disease has been observed during the 5 years follow-up .
