A rare malignant transformation of endometriosis

A 48-year-old female was admitted to our hospital with worsening anal heaviness, distension and dull pain in the lower abdomen for 4 months, and abnormal defaecation for 10 days. Bilateral ovarian endometriosis cyst excision had been performed 9 years previously. Physical examination revealed: (i) an obviously thickened and contracted right sacro-iliac ligament in nodular shape with a size of ∼4*4 cm2, protruding to the right pelvic wall; and (ii) a touchable mass of ∼8*7 cm2 within the rectovaginal septum, compressing the vagina forwards and the rectum backwards.
