Cutaneous hamartoma of adnexa and mesenchyme. A variant of folliculosebaceous cystic hamartoma with vascular-mesenchymal overgrowth.

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.
