MESONEPHRIC REMNANT HYPERPLASIA OF THE CERVIX - A CLINICOPATHOLOGICAL ANALYSIS OF 14 CASES

Lesions derived from mesonephric remnants in the uterine cervix are rare. We describe 14 patients with benign, hyperplastic mesonephric remnant lesions. The patients ranged in age from 31 to 81 years (mean, 47). Four were postmenopausal. The lesions were incidental findings in all but 2 of the patients and frequently had been submitted for consultative pathologic opinion. Two patients did, however, present with symptoms (vaginal bleeding) likely attributable to their lesions and 1 of them had a cervical abnormality on clinical examination. Microscopically, the lesions were composed of lobular or diffuse proliferations of small, round mesonephric tubules which were frequently deep within the cervical wall and often extended to the surface of the cervix. Five of the patients had a referring diagnosis of probable or definite cervical adenocarcinoma due to the infiltrative appearance of the lesions. No mesonephric carcinomas were encountered. Hyperplastic lesions of mesonephric remnants are usually benign, incidental findings but may on occasion be associated with clinical symptomatology and are a potential source of diagnostic confusion for the pathologist. © 1993 Academic Press, Inc.
