A Variant of Folliculosebaceous Cystic Hamartoma with Vascular-Mesenchymal Overgrowth

Abstract

We describe a hamartoma with folliculosebaceous and mesenchymal components. Striking vascular-mesenchymal elements distinguish this entity from previously described hamartomas and other adnexal proliferations. It is also distinct from the recently described folliculosebaceous cystic hamartoma but likely represents a variant with mesenchymal overgrowth.
