Definition of Rhabdomyoma

Rhabdomyoma is a benign (noncancerous) tumor that originates in muscle tissue, usually skeletal muscle.

Rhabdomyoma is somewhat more common in children than adults.

The doctor may choose to surgically remove the rhabdomyoma to obtain a definitive diagnosis and rule out cancer. However, rhabdomyoma does not become cancerous.

Rather, it may have the appearance of a cancerous tumor so the doctor removes it for biopsy and laboratory analysis. Rhabdomyoma may occur in the heart, presenting a potentially life-threatening situation that usually requires surgery to remove the tumor.
