"Macroscopically leiomyomas of the deep soft tissues are circumscribed tumours with a tan-grey to white sometimes reddish-tan colour and and a rubbery consistency. They might have myxoid changes and can get quite large up to 15 cm and retroperitoneal lesions even larger 1."

"Immunohistochemistry stains are reactive for smooth muscle actin, desmin and h-caldesmon and negative for S100 and CD34 1,2. Retroperitoneal soft tissue leiomyomas are positive ER, PR and WT1 1,2,4, whereas somatic soft tissue leiomyomas do not express ER or PR 1."
