Abstract:
A case is reported about a patient who was originally treated for bilateral retinoblastoma and subsequently developed an embryonal rhabdomyosarcoma in the masseter. Such patients have a genetic predisposition to a second malignancy that statistically far exceeds the rate for the general population. In addition, current treatment methods also increase the patient's susceptibility to another malignancy. This case emphasizes the necessity of maintaining a high degree of clinical suspicion in the evaluation of any lesion that may appear subsequent to the treatment of cancer in children, particularly bilateral retinoblastoma.
