Abstract:
Hibernoma is very rarely encountered and is expressed in the various names including "lipoma of brown fat", "fetal lipoma", and "lipoma of embryonic fat". In our knowledge, only about 50 cases have been reported in the literature of the Western world, and no case reports have been published in Korea. In May 1986, we experienced a case of hibernoma occuring in a 16 old years boy. On physical examination, a relatively well defined nodule was noted on the right scapular region. A total removal of the lesion was done under the clinical diagnosis of epidermal inclusion cyst. On gross examination, the specimen consists of three irregularly shaped portions of yellowish brown soft tissue, measuring up to 0.8 cm in greatest dimension. Microscopically, the tumor showed distinct lobular pattern separated by fibrovascular bands. The lobules were composed of multivacuolated or eosinophilic granular cells showing centrally located small unclei. A brief review of the literature was done.
