Adult cellular rhabdomyoma (ACR), is a noncancerous primary tumor of the heart, similar to other adult skeletal muscle tumors outside the heart and distinct from cardiac rhabdomyoma.[1] It typically occurs in peopl older than 2-years of age.[2]
Unlike cardiac rhabdomyoma, adult cellular rhabdomyoma is not associated with any syndrome, and does not have the "spider cells" with vacuoles, which are characteristic of cardiac rhadomyoma.[2] ACRs appear well defined, of uniform tan color, and protrude into the chambers of the heart.[2]
It is rare and accounts or less than 2% of soft tissue tumors.[1]
