“…10 Cytologically, FNA of pleomorphic lipoma reveals mature fat, spindle cells, and bizarre pleomorphic giant cells, including floret cells. [11][12][13] Histologically, there are five key features: (1) circumscription with encapsulation (in contrast to liposarcoma), (2) characteristic floret cells, (3) lack of prominent vascularity, (4) rarity of lipoblasts, and (5) extremely rare mitotic figures. Pleomorphic lipoma may also have coarse, birefringent interstitial collagen, and inflammatory cells.…”

Pleomorphic lipoma is a rare lipocytic neoplasm that most commonly occurs in the head and neck region in middle-aged to elderly men. Clinically, it presents as a slow-growing, well-circumscribed subcutaneous mass. Histopathologically and cytogenetically, it has some features overlapping with other benign and malignant tumors, such as benign spindle cell lipoma, atypical lipomatous tumor, liposarcoma, and malignant fibrous histiocytoma. However, cure rates are high when pleomorphic lipoma is treated with complete surgical excision with clear margins. Therefore, an accurate preoperative diagnosis is very important for proper treatment. Due to the rarity of this tumor, few cases diagnosed by cytology have been reported in the English literature. Here, we report two cases of pleomorphic lipoma, the diagnoses of which were suggested on fine needle aspiration biopsies and subsequently confirmed by surgical excisions.

“…However, FNA is not definitive, and tissue diagnosis is recommended for confirmation. [12][13][14] Pleomorphic lipoma is treated with complete surgical excision with clear margins. Although these lesions are benign, they may recur if incompletely excised.…”

“…Well-differentiated liposarcoma applies to deep-seated lesions in the retroperitoneum, spermatic cord, and mediastinum, where recurrence and local aggressiveness are possible; atypical lipomatous tumor applies to lesions of the limbs and trunk that do not recur if adequately excised. 11,24,43,48,51 The first impression might be that of a lipoma, but the clinical presentations of lipomas and liposarcomas are generally so different that this rarely presents a significant dilemma. 16.5) are admixed with blood and extruded lipid.…”
