Pleomorphic Lipoma of the Neck: A Benign Lesion Mimicking Liposarcoma

Pleomorphic lipomas are a rare variant of lipomatous tumors. They typically occur in older males and show a tendency to develop over the posterior neck, shoulder, and back. Clinical presentation, rate of growth, and histologic features of these benign lesions are key factors in making an accurate diagnosis and in distinguishing them from liposarcomas. Complete surgical excision with clear margins is curative. This paper presents a case report and a discussion intended to aid the clinician in using the histological findings to help differentiate a pleomorphic lipoma from its malignant counterparts.
