Pleomorphic Lipoma – A Cytologic Diagnostic Dilemma

Abstract

Pleomorphic lipoma is a rare benign tumor that most commonly present as subcutaneous mass lesion in neck, shoulder and back of middle aged men. Fine needle aspiration (FNA) of these lesions can present a diagnostic challenge. Its large, hyperchromatic cells and multinucleated forms (floret) can be easily mistaken for malignancy. Due to rarity of this tumor, few cases diagnosed by cytology have been reported in English literature. Here, we report a case of pleomorphic lipoma, the diagnosis of which was suggested on FNA and subsequently confirmed by surgical excision.
