The body of the uterus is enlarged and distorted by a tumour some 6 cm. in diameter, which also
distorts the endometrial canal. The right-hand side of the tumour shows the usual structure of a
leiomyoma, but the left half has a totally different appearance and is sarcomatous (the word means
fleshy). It is likely that the tumour is invading the wall of the uterus. A smaller, benign leiomyoma
is present beneath the serosa. The cervix shows a large Nabothian follicle.
