BACKGROUND: Pleomorphic lipoma is a rare, benign, pseudosarcomatous, soft tissue neoplasm typically involving the subcutis of the neck and shoulder in middle-aged to elderly men. It is characterized histologically by atypical, multinucleated giant cells and grossly as a well-circumscribed mass. Since this neoplasm can resemble a sarcoma, histopathologic diagnosis is critical in preventing unnecessary surgery. OBJECTIVE: To describe a case of pleomorphic lipoma in the neck and to review the clinical and histopathologic characteristics of this neoplasm. METHODS: We present a case report and review of the literature. RESULTS: Local excision to completely extirpate this neoplasm has proven curative at 10 months of follow-up. CONCLUSION: Pleomorphic lipoma is superficially located and may be encountered in a dermatologic setting. Thus the dermatologist should become familiar with its clinical presentation and microscopic appearance.
