BENIGN GLANDULAR INCLUSIONS IN INGUINAL A ND ABDOMINOPELVIC LYMPH-NODES

From 4 cases recently seen at the Institut Gustave-Roussy, this report describes the pathological and evolutive features of benign glandular inclusions in inguinal, pelvic or abdominal lymph nodes. These lesion s are defined by the presence of tubular formations in lymph nodes, li ned by a single layer of epithelium which is cuboidal or columnar and resembled that of tubal epithelium with ciliated, secretory and interc alary cells. In most cases, benign glandular inclusions in lymph nodes still quiescent. In rare instances, they may proliferate and become p apillary. The association of proliferating glandular inclusions in lym ph nodes with borderline tumor of the ovary raises the problem of thei r primary or metastatic origin. However, their pathological features a rgues for a primary origin in lymph nodes. Thus, we think that a metas tatic potential of borderline tumors of the ovary is not supported by any convincing argument.
