Recurrent targetoid hemosiderotic hemangioma in a 26-year-old man

A 26-year-old previously healthy man presented with a 6-mm violaceous papule that had a surrounding 1.5-cm annular, nonblanching, erythematous halo on the right-sided flank. The man reported the lesion had been recurring for 4 to 5 years, flaring every 4 to 5 months and then slowly disappearing until the cycle recurred. Targetoid hemosiderotic hemangioma was clinically diagnosed. The lesion was removed by means of elliptical excision and the condition resolved. The authors discuss the clinical appearance, histology, and etiology of targetoid hemosiderotic hemangiomas.
