Multi-institutional study of mesonephric-like adenocarcinoma: its clinicopathological characteristics and histogenetic association with ectopic endometrium
Virchows Archiv : an international journal of pathology ·doi:10.1007/s00428-025-04286-0

To explore the clinicopathological features and origin of mesonephric-like adenocarcinomas (MLAs), 83 cases diagnosed or suspected to be MLAs were collected from various institutions in Japan. We clearly classified 78 as MLAs (uterus: 47, o…

Premature Classification of Early-stage Endometrioid Ovarian Carcinoma With Mesonephric-like Differentiation as Mesonephric-like Adenocarcinoma
International journal of gynecological pathology : official journal of the International Society of Gynecological Pathologists ·doi:10.1097/pgp.0000000000001002

Ovarian mesonephric-like adenocarcinoma (MLA) is a rare tumor with potential origins in endometriosis and Müllerian-type epithelial tumors. The morphologic patterns of MLA overlap with those of endometrioid ovarian carcinoma (EnOC). We spec…
