Two cases of cutaneous endometriosis

Cutaneous endometriosis (CEM) is a rare cutaneous manifestation of a common gynecological disease. More than 70% of CEM lesions are seen at sites of previous surgical scars, however primary lesions can arise de-novo in previously normal epithelium. The clinical presentation can vary and mimic other common dermatologic conditions. We present 1 primary and 1 secondary case of young healthy African American women with umbilical CEM. A 30-year-old woman presented with 2 umbilical lesions present for 1 year, associated with intermittent pain, swelling, and bleeding with menstrual cycles.
