Cutaneous apocrine cystic adenolipoma.

Adenolipoma is a rare microscopic variant of cutaneous lipoma composed of large lobules of mature adipocytic tissue admixed with eccrine ducts and glands. We report a new case of cutaneous adenolipoma, and the first showing an apocrine cystic glandular component. This lesion may not be a specific entity, and could represent entrapment of epithelial structures within a lipoma.
