Hibernoma cervical e lipoblastomatose

Cervical hibernoma and lipoblastomatosis

Lipoblastoma and lipoblastomatosis are rare benign soft-tissue tumoral lesions resembling fetal adipose tissue. A total of 16 cases of lipoblastoma of the neck were reported in the literature, and only 3 were described in the posterior side of the neck. Hibernoma is a rare benign adipose tumor composed of brown fat cells and only about ten cases occurring in the cervical area have been reported...

Hibernoma of cervical region

A 42 year old male presented with swelling in the right posterior cervical region for a period of 2 months. Palpation revealed a soft, non tender, mobile swelling measuring 2 x 1 cms. An elective excision biopsy was performed. Gross examination showed a yellow to pale brown soft mass.

Cervical hibernoma in a two year old boy

Hibernomas are uncommon benign soft tissue tumours mimicking brown fat. They are mostly seen in the fourth and fifth decades of life. Only few cases in the cervical area have been reported. Because of its rarity in pediatrics and difficult diagnosis, we report a tow year-old patient with a cervical tumor. Ultrasound and computed tomography exams showed an infiltrative, with hypervascular and li...

Intrathoracic hibernoma.

loculated fat cells morphologically similar to the hibernating gland tissues found in animals was first recognized 95 years ago. It was subsequently termed “hibernoma.” In 1966, 38 cases had been recorded, 4 of which were intrathoracic. Thirty years later, approximately 100 cases had been reported, of which only 7 were intrathoracic. A recent review of the English literature reveals 13 intratho...
