title: Ovarian serous borderline epithelial tumors with multiple retroperitoneal nodal involvement: metastasis or malignant transformation of epithelial glandular inclusions?
abstract: One of four patients who underwent lymph node excision at exploration for ovarian serous borderline epithelial tumor (OSBT) at Baystate Medical Center was found to have FIGO Stage III C lesion associated with extensive ovarian external (surface) papillary growth, peritoneal implants in the omentum and cul-de-sac, and involvement of multiple pelvic and periaortic lymph nodes by the tumor. Histologically, the lymph nodes showed an admixture of endosalpingeal glandular inclusions with neoplastic tissue identical to the ovarian tumor. The exact histogenesis and the prognostic significance of the nodal involvement by OSBT are still not fully understood. Although there is a small number of reported cases of lymph node involvement associated with OSBT, they are described as examples of nodal metastases or independent primary foci of malignant transformation. This paper presents an interesting association of OSBT with extensive pelvic and periaortic nodal involvement and reviews the relevant literature.
