Clinicopathological correlation of three cases of metastatic carcinoma to uterine cervix: An institutional experience

Abstract

Abstract Introduction/Objective Metastasis to the female genital tract presents a rare occurrence and poses significant diagnostic hurdles. The uterine cervix, although less frequently implicated, presents additional challenges for metastatic spread owing to its diminutive dimensions, limited vascular perfusion, and abundance of fibrous tissue. Clinical manifestations often include abnormal vaginal bleeding in 62–75% of cases, frequently accompanied by involvement in other anatomical sites. Accurate identification of cervical tumor activity and its primary origin holds paramount importance for precise diagnosis, therapeutic stratagem, and prognostic assessment. Methods/Case Report Here we are reporting three cases that were encountered in our institution over a 5-year period. The first patient, a 63-year-old female with a history of breast cancer, six years later exhibited metastatic breast cancer in a cervical polyp, confirmed by positivity for AE1/AE3, GATA3, ER, and negativity for TTF-1, chromogranin, synaptophysin, PAX8, inhibin, calretinin, CDX-2, CD10, desmin, smooth muscle actin, S100, and HMB-45. The second patient, diagnosed with pancreatic adenocarcinoma, two years later manifested cervical metastasis confirmed via positive staining for CK7, CDX2, and focal p63, and did not express PAX8, vimentin, ER, p16, synaptophysin, and chromogranin. The third patient, diagnosed with lung adenocarcinoma, one year later presented with a cervical mass, histologically confirmed as metastatic lung adenocarcinoma via positivity for CK7, Napsin A, and TTF1, and negativity for PAX8, p16, p40, p53, GATA3, and ER. Results (if a Case Study enter NA) N/A Conclusion Given the challenges of identifying metastasis to the cervix, thorough diagnostic evaluation should be undertaken to differentiate primary versus metastatic disease in women with a history of non-cervical malignancy.
