Scar Endometriosis: A Case Series and Review of Literature

Endometriosis is a common and distressing gynecological problem in women of reproductive age group. Endometriosis is the presence of functioning endometrial tissue outside the uterine cavity, and may be found either inside the pelvis or outside the pelvis. It presents as red, petechial lesions, usually multiple, on the peritoneal surface of the uterus, ovaries, and fallopian tubes. The most common organ that gets involved is the ovary (almost 50% cases) followed by the pouch of Douglas and broad ligament. It can also be present on the bowel, may erode the bowel, and cause passage of blood in stools. In very rare cases, it is found in the thorax, central nervous system and urogenital tract, as also in the skin where previous surgery was undertaken (abdominal surgical scar). Scar endometriosis is rare and diffi cult to diagnose. Here, we are discussing the pathogenesis, diagnosis, and treatment of this condition along with a review of the literature, so that this paper will increase the awareness of this, often misdiagnosed, rare condition called scar endometriosis.
