Although most frequently diagnosed in the head and neck [11] or the genitourinary system, RMS may occur anywhere in the body. Embryonal histology is usually found in the head and neck, genitourinary tract, or orbit. Alveolar RMS (see Pathophysiology) is usually encountered in the extremities, trunk, or perineum. The botryoid variant arises in cavitary structures such as the vagina and bladder, and spindle cell RMS is found most commonly in the paratesticular area.
