NCI Definition: A benign smooth muscle neoplasm arising from the body of the uterus. It is characterized by the presence of spindle cells with cigar-shaped nuclei, interlacing fascicles, and a whorled pattern. [1]

Uterine corpus leiomyomas most frequently harbor alterations in USP28, TSC2, TSC1, TP53, and RUNX1 [2].

Most Commonly Altered Genes in Uterine Corpus Leiomyoma

USP28 R732H, TSC2 R691L, TSC2 Mutation, TSC1 Mutation, and TSC1 M351V are the most common alterations in uterine corpus leiomyoma [2].
