The pathological appearances of uterine leiomyomas at macroscopic, histological and ultrastructural levels are described and illustrated. This is just what it sounds like. counts a leiomyoma may turn out to be a benign tumor. proposed criteria to classify STUMP tumors divided into 4 categories based upon the degree of cellular atypia, presence of coagulative necrosis, and mitotic index [1-4,9].1) Atypical leiomyoma: Diffuse moderate to severe cellular atypia without coagulative cell necrosis and a mitotic index <10 mitotic figures/10 hpf. Affected individuals develop cutaneous and uterine leiomyomas and aggressive RCC.
