ABSTRACT
Endometriosis is defined as the presence of endometrial glands and stroma outside the uterine cavity. Endometriosis may involve a wide spectrum of anatomic locations, but it typically involves pelvic locations. We report the case of a 45-year-old woman who presented with a history of abdominal pain and swelling. She first noticed the swelling eight months prior to presentation, and it had gradually progressed in size. The patient reported that the swelling increased in size during menses. Physical examination revealed a well-defined firm mass to the right of the midline. The mass had a smooth surface but limited mobility after abdominal wall muscle contraction, suggesting an infiltration of the underlying muscular structures. The findings demonstrated by computed tomography of the abdomen confirmed the diagnosis of abdominal wall endometrioma. The patient underwent successful resection of the lesion with complete resolution of her symptoms.
