幼小児にみられた上咽頭横紋筋肉腫について

抄録

Present authors reported two cases. of rhabdomyosarcoma in children, which is of rare occurrence also in the field of otorhinolaryngology.
One of the cases encountered in a 6-year-old male in whom the tumor responded strikingly to radiation therapy so impressing the authors an eventual success in treatment. Regretably however, the tumor showed an inveterate recurrence ten months after the conclusion of the treatment.
The authors added another case of 8-year-old female seen at the Japan Cancer Institute. Literatures were reviewed and some discussions were made on this disease.
