Adenomatoid Tumor of Fallopian Tube with Intratumoral Endometriosis: What Mind Doesn't Know, Eyes Don't See

Abstract Adenomatoid tumor, a benign tumor of mesothelial origin, is seen most commonly in paratesticular tissue in males and uterus in females. Its incidence is extremely rare in the fallopian tube, with only few such case reports. In the present case, an incidental association of adenomatoid tumor of the fallopian tube with turbo-ovarian endometriosis and ipsilateral nonfunctioning kidney was seen. Intraoperatively, a small nodular lesion was seen over the tubal wall. On a detailed review of literature, we found very few cases of adenomatoid tumor of the fallopian tube. The other unique finding was the occurrence of intratumoral endometriosis within the adenomatoid tumor.
