Low-Grade Serous Carcinoma Arising In Inguinal Nodal Endosalpingiosis: Report Of 2 Cases And Literature Review

We report 2 cases of low-grade serous carcinoma probably arising from endosalpingiosis within inguinal lymph nodes. The neoplasms occurred in 51- and 58-yr old women in the absence of tumor within the adnexa, peritoneum or elsewhere. These represent the first reported examples of low-grade serous carcinoma arising within and confined to inguinal nodes. We review the pertinent literature regarding primary nodal low-grade serous carcinoma.
