Cervical hibernoma. Review of the literature and a new case.
Hibernoma is the designation for a rare, benign, soft-tissue tumour composed of cells similar to those of brown adipose tissue. Review of the world literature reveals about 80 cases, but only six hibernomas in the cervical region have previously been reported. A case of cervical hibernoma showing descending behaviour is presented, and the histological, histogenetical, and clinical features of hibernomas are discussed. It is stated that the tumours are adequately treated by local excision, as the neoplasms are histologically and clinically benign, but the extensive vascularity may cause troublesome bleeding in some instances.
