Mucosal angioleiomyoma: mucoscopic findings adding value to diagnosis.

This article presents a female patient in her 40s who presented with a tender violaceous bump on her upper right lip. Our primary differential diagnosis was an arteriovenous malformation. Punch biopsy revealed the lesion to be an angioleiomyoma (ALM). The punch biopsy was sufficient for the complete removal of the lesion, and the lesion did not recur to date. There were no complications. We discuss the dermatoscopic description of an ALM and its clinical picture.
