Pleomorphic Lipoma on the Scalp of a Middle-aged Woman / 대한피부과학회지

ABSTRACT

Pleomorphic lipoma is an asymptomatic, slowly growing, solitary, well-circumscribed dermal or subcutaneous benign tumor. It is commonly found on the back or the neck of elderly male patients. Clinically, the lesion looks like a lipoma. Histopathologically, mature and immature fat cells are situated singly or in groups in a mucinous stroma. There can also be floret giant cells with overlapping nuclei. Histologically, pleomorphic lipoma may resemble liposarcoma but behaves in a perfectly benign manner. Our case is unique in terms of the sex and location of the tumor. In our case, complete excision was performed, and the patient shows no sign of recurrence 1 year after surgery. We herein report a case of pleomorphic lipoma which developed on the scalp of a 49-year-old female.
