Embryonal rhabdomyosarcoma of the head and neck in children and adolescents

Abstract

ARCOMA botryoides in female infants and its analogue, the sarcoma developing in the vicinity of the bladder base and prostate in male infants, are well known to pathologists and clinicians alike. T h e pronounced tendency toward the appearance of embryonal striated muscle in these tumors has led to their designation as embryonal rhabdomyosarcoma, although the occurrence of other mesenchymal elements may justify the terms "mixed mesenchymal tumor" or "niesenchymoma." T h e former of these is probably not to be preferred because of its more recent employment to designate the complex endometrial tumors of the uterus in the adult, tumors different histologically, histogenetically, and behavioristicall y.
