\n\tPrimary and Secondary Umbilical Cutaneous Endometriosis: Two Case Reports

\n\tCutaneous endometriosis (CEM) is a rare cutaneous manifestation of a very common gynecologic disease among middle-aged women. Cutaneous lesions are commonly seen at sites of previous surgical scars, but can also arise de-novo in normal epithelium. The clinical presentation alone can vary widely and mimic other common dermatologic conditions. Histopathologic examination is often needed to confirm the diagnosis. Here we will present both a primary and secondary case of CEM in attempts to portray the wide variation in physical exam findings so CEM may be considered in the differential for cutaneous masses in the umbilicus.
