Multiple mucinous and lipomatous variant of eccrine angiomatous hamartoma associated with spindle cell hemangioma: a novel collision tumor?
Eccrine angiomatous hamartoma (EAH) is a rare, benign condition characterized histologically by increased numbers of eccrine elements, as well as numerous capillary channels. In most cases, EAH arises as a single lesion; however, multiple variants have been reported. We report a 35-year-old female patient with multiple, sudoriparous, subcutaneous nodules on the right foot, which showed typical histopathological findings of EAH, and vascular components of the tumor consisted of thin-walled dilated vascular spaces intermixed with spindle cells and some histiocytoid endothelial cells representing spindle cell hemangioma (SCH). To our knowledge, the co-existence of EAH with SCH is a novel finding and not yet described.
