[Hibernoma. Presentation of a case]

Hibernoma. Case report. Although well defined in its morphological features, hibernoma still remains an interesting type of tumor, due to its rareness. The case here presented shows the morphological characteristics of a lesion which could be classified as intermediate between simple lipoma and typical hibernoma, with lipoblastic-like cells similar to those we find in lipoblastomas and lipoblastomatosis. The pictures suggest the idea that this lesion may be the result of a maturing process toward well differentiated tumors, as pure lipomas and typical hibernomas.
