Hibernoma – two patients with a rare lipoid soft-tissue tumour

BACKGROUND Hibernomas are rare benign soft-tissue tumours arising from brown fat tissue. Although imaging characteristics are not specific certain imaging features, common locations and patient demographics may suggest hibernoma as a differential diagnosis. CASE PRESENTATION We report on two 48-year-old male patients with hibernoma. The tumour presented with local swelling of the inguinal reg...

Hibernoma--a rare brown fat tumour.

Hibernoma is a rare benign tumour of brown fat. It is also known as lipoma of brown adipose tissue, lipoma glandular and atypical lipoma. The hibernoma was first described by Merkelin 1906, who called it Pseudolipoma. The name hibernoma is derived from its histological similarity to the brown fat of hibernating animals. They have been found in the neck, back, popliteal space, thighs, axilla, ab...

Soft tissue giant cell tumour of low malignant potential: a rare tumour at a rare site.

"Soft tissue giant cell tumour of low malignant potential" is considered as the soft tissue counterpart of osteoclastoma of the bone. It is a primary soft tissue tumour which is classified under the category of fibrohistiocytic tumours of intermediate malignancy.Seventy percent of the tumours involve the extremities and only about seven percent of them arise in head and neck region. They are co...

Soft Tissue Giant Cell Tumour of Low Malignant Potential: A Rare Tumour at a Rare Site

Deep-seated huge hibernoma of soft tissue: a rare differential diagnosis of atypical lipomatous tumor/well differentiated liposarcoma.

BACKGROUND Hibernoma is a rare benign fat-forming soft tissue tumor that differentiates similar to brown fat, hence an origin from remnants of fetal brown adipose tissue has been proposed. Mainly young adults are affected, usually without significant clinical symptoms. MATERIAL AND METHODS We report on four patients with hibernomas, who were treated at our hospital during the last 10 years. T...
