Embryonal rhabdomyosarcoma of the hand. A case of mediastinal relapse 103 months after treatment.
A 9-year-old boy was seen to have embryonal rhabdomyosarcoma of his right hand. He was treated with surgery, radiotherapy and adjuvant combination chemotherapy and remained free of disease for 103 months. He then developed signs of upper respiratory tract obstruction and a mass in the superior mediastinum was found. Histopathological and immunohistochemical studies confirmed metastatic embryonal rhabdomyosarcoma. This very unusual, long, relapse-free interval is discussed.
