rhab·do·my·o·ma (rab″do-mi-oґmə) [rhabdo- + myoma] a benign tumor derived from striated muscle. The cardiac form is considered to be a hamartoma and is often associated with tuberous sclerosis; the extracardiac form is a true neoplasm and is often divided into fetal and adult forms on the basis of the degree of cellular differentiation, distribution, patient age, and other factors.
