Abstract
Primary signetring cell adenocarcinoma of the cervix is very rare and less common than metastatic signet-ring cell adenocarcinoma. To the best of the authors' knowldge only one genuine case has been reported to date. Tvvo cases of primary signeting cell adenocarcinoma of the uterine cervix in patients aged 68 and 74 years are presented. The tumors were in stage IB. The light microscopic findings were conirmed by histochemical and immunohistochemical study. DNA nuclear analysis by flow cytometry of the neoplasms revealed an aneuploid (tetraploid) pattern. The paients had no evidence of recurrent or metastatic disease 35 and 25 months after a radical hysterectomy with bilateral salpingo-oophorectomy and lymph node dissecion respectively. Primary signet-ring cell adenocarcinoma of the cervix should be diferentiated from metastatic adenocarcinoma, endocervical involvement by signeting cell carcinoma of the endometrium, benign mucinfilled signet-ring cell aggregates that may accumulate in mucosal folds, microglandular hyperplasia, muciarminophilic histiocytosis, and other malignant neoplasms that may have signet ringlike cells and deserve consideration such as squamous cell carcinoma, maligant lymphoma, myeloma, and malignant melanoma. Although very rare, signeting cell adenocarcinoma of the cervix can exist as a primary tumor. Distinction beween a primary neoplasm and a metastasis to the cervix is decisive for treatment and prognosis.
