Giant adrenal lipoma: a report of two cases and review of literature.

Lipoma of the adrenal gland is extremely rare. We report two cases of adrenal lipomas, one in a 64-year-old female and the other a 78-year-old male. The sizes of these tumours (4.5 cm and 8 cm) were larger than those reported in the literature. Both cases were found incidentally, one at autopsy and the other during ultrasonographic examination for unrelated condition. The histogenesis, clinicopathological features, differential diagnosis and management of these cases are discussed.
