Peritoneal metastasis in Stage IB1 adenocarcinoma cervix: A rare entity

The presence of ovarian or peritoneal metastasis in early-stage cervical malignancy is a rare entity. It often poses a diagnostic challenge whether it is a synchronous primary tumor or a metastatic lesion. A 63-year-old postmenopausal woman presented with Stage 1B1 carcinoma cervix with ascites, and a 5.8 cm x 4.2 cm x 3.5 cm left solid adnexal mass. She underwent Type III radical hysterectomy, excision of peritoneal mass, with bilateral pelvic and paraaortic lymphadenectomy and infracolic omentectomy. On histopathology, cervix showed features of adenocarcinoma, and the peritoneal mass revealed similar histomorphology as cervical growth with metastatic tumor deposits in omentum. Immunohistochemistry (IHC) was utilized to determine the origin of mass. The early stage disease and histology may not always predict the distant metastasis. Therefore, a thorough pretreatment evaluation, meticulous intraoperative assessment, and IHC are mandatory for optimum management and prognostication.
