Abstract

Introduction:

Mesonephric carcinoma is a rare type of epithelial tumor of the uterine cervix which derive from the remnants of the paired mesonephric (Wolff's) ducts. The incidence of such neoplasms is difficult to determine due to rarity, previous misclassification of clear cell carcinomas and yolk sac tumours as mesonephric carcinomas and potential underreporting due to misclassification of mesonephric carcinoma as Mullerian tumours or mesonephric hyperplasia. The evidence regarding the clinical course, prognosis and optimal treatment is limited.

Materials and Methods:

Searches were performed on MEDLINE, EMBASE and Google Scholarly articles. All the relevant articles were included in the study. Only approximate 40 cases have been reported till now.

Discussion:

Mesonephric adenocarcinoma cervix has different morphologies like ductal, tubular, solid, retiform, sex-cord like pattern, clear cell and serous papillary structures. IHC assessment is helpful in differentiating it from Mullerian counterpart, as it is negative for CEA, CK20, p16, PAX2, ER/PR and vimentin and positive for CD10, calretinin, CK7, CAM5.2 and EMA. It has no relation with HPV infection. Unlike squamous epithelial carcinoma, it is rarely presenting with the abnormal cervical smear result, has more advanced age at presentation and its incidence does not appear to decline with age. The diagnosis has been supported by endometrial curettings, directed/cone cervical biopsies and hysterectomy specimens. The majority of patients are diagnosed at stage IB with mean DFS of 48.6 months. Recurrence rate is 23%, with a mean interval of 40 months. Hysterectomy is the primary treatment. Advanced stage disease of adenocarcinoma seemed to respond to radiotherapy, but for the MMMTs the combination of chemotherapy with radiotherapy appears to be preferable.

Conclusion:

Rarity of the neoplasm, varied morphology, mix presentation and very low number of cases leads to difficulty in correct diagnosis in a small biopsy specimen. IHC helpful in differentiating it from other lesions.
