Endometriosis is characterized by the presence of histological normal endometrial tissue outside the uterine cavity. It occurs in up to 15% of menstruating women and often goes undetected. Some cases of soft tissue involvement have been reported, particularly in the skin and subjacent tissues of surgical scars. We came cross a 42-years old patient with a 3x3cm mass under nearly 3 cm inferior of umbilicus. Incisional or “scar” endometriosis often occurs in the absence of the more typical pelvic involvement. Although definitive diagnosis still requires biopsy, the patient’s cyclic symptoms and history of previous uterine surgery, should suggest the correct diagnosis. But, in cases like ours cyclic symptoms will not be available.
