Two cases of alveolar rhabdomyosarcoma presented as lid lesions thought initially to be of vascular origin. Both were positively diagnosed only by electron microscopy. They represent the first cases of alveolar rhabdomyosarcoma of the orbit or adnexal structures so diagnosed. Length of survival in case 1 is also unusual.
