This paper is a case report of a 54-year-old woman who developed a large suprapubic mass at a Cesarean section scar, where imaging and pathology supported endometriosis in the scar that progressed to carcinoma. The authors describe an endometrioid carcinoma developing within scar endometriosis, noting that malignant transformation of scar endometriosis can occur and that endometrioid carcinoma is the most common histologic pattern; however, they highlight that clear cell carcinoma arising in this setting is very unusual and present their case as a first documented example in Korea. A key limitation is that, as a single case report, it does not establish incidence or causal mechanisms beyond the described clinical course. This paper is centrally about endometriosis — specifically malignant transformation of Cesarean section scar endometriosis into clear cell carcinoma.

Abstract

Endometriosis of a surgical scar is rare and occurs mainly when a hysterectomy or Cesarean section was performed. We describe a 54-year-old woman with a large suprapubic mass as a definite case of a endomerioid carcinoma developing within the scar endometriosis following Cesarean section. Scar endometriosis, as well as endometriosis at other sites, can turn malignant. Endometrioid carcinoma is the most common histological pattern of malignant tumor arising in endometriosis. But clear cell carcinoma is very unusual. A case of primary clear cell carcinoma in endometriosis of a Cesarean section scar is described. To the best of our knowledge, this is the first documented case of endomerioid carcinoma developing within the scar endometriosis in Korea.
