Mucoepidermoid carcinoma as a secondary malignancy in pediatric sarcoma
Neoplasms, Second Primary
Primary mucoepidermoid carcinoma of the parotid gland accounts for less than 10% of all head and neck tumors in childhood. Previous series of secondary mucoepidermoid carcinoma have demonstrated an increased risk in patients with leukemia/lymphoma. This is the first reported series of parotid mucoepidermoid carcinomas occurring after sarcoma treatment without radiotherapy. A common link between the 2 patients may be the use of alkylating therapy.
