AB Leiomyo-adenomatoid tumour (LMAT) is a rare benign neoplasm and very few cases of LMAT of the uterus are documented in the literature. Uterine LMATs are usually detected incidentally during the histopathologic evaluation of routine myomectomy or hysterectomy specimens for leiomyomata. Thorough evaluation of the morphological features and a concise immunohistochemical panel allows for accurate classification of this benign neoplasm.

This transformation is postulated to occur as the result of acquired genetic alterations, some of which may be eligible for targeted therapy.
