Multifocal Liposarcomas of the Chest Wall-A Case Report

Abstract

We present a rare case of multifocal liposarcomas that originated in the chest wall. A 61-year-old woman palpated a mass lesion in her left chest wall, at the subclavicular area. Intermittent local tenderness and radiation pain to the left arm were noted. On physical examination, an elastic and mobile tumor measuring 5×3 cm was palpated in the left chest wall. Ultrasonic examination revealed that the tumor was well defined and heterogenous in density. Under the impression of a chest wall lipoma, she underwent excision of the tumor. After removing the superficial larger tumor, another deep, dumbbell-shaped tumor was found by finger palpation. Excision of the deeper tumor was performed, as well. Histopathological findings revealed that the tumors were well-differentiated, sclerosing liposarcomas containing cells with atypia, hyperchromatic nuclei and occasional lipoblasts. During 12 months of follow-up, no local recurrence was noted. There has been no report in the literature of chest wall liposarcomas presenting as multifocal tumors.
