Hibernoma. A case report.

Hibernoma is a rare soft-tissue tumor clinically presenting as a firm, freely movable, nontender mass, most commonly in the interscapular region. It is slow growing and usually asymptomatic. Examination of the overlying skin may demonstrate evidence of hypervascularity. On gross examination, the tumor is encapsulated and highly vascular, with its color varying from tan to reddish brown. Microscopic examination is usually diagnostic, demonstrating the characteristic multivacuolated oval or polygonal cells. Because of its benign character, treatment consists of simple excision. This article describes a case of a patient with hibernoma.
