Cutaneous Angioneurofibroma: A Vascularized Histopathologic Variant of Neurofibroma

Angioneurofibroma is a rare histopathological variant of cutaneous neurofibroma, characterized by a more densely vascularized stroma when compared to classic neurofibroma. Here we describe a case of this entity, which presented as a tender penile plaque in a young man, and discuss the clinicopathologic differential. The unique histologic findings in this case supports the recognition of angioneurofibroma as a distinct subtype of neurofibroma, and dermatologists should be aware of this rare variant.
