A case of nasopharyngeal mucoepidermoid carcinoma in a 5 year-old female patient

Malignant salivary gland tumors only represent 0.08% of all childhood tumors. Especially, nasopharyngeal mucoepidermoid carcinoma(MEC) in pediatric age is an extremely rare malignancy. We hereby report a case of nasopharyngeal MEC in 5 year-old female patient. The patient underwent the complete removal of the tumor by endonasal endoscopic approach. Adjuvant postoperative radiotherapy was not considered. After 3.5 years of follow-up, there are no sign of recurrence and metastasis. Minor salivary gland tumor must be considered as a differential diagnosis of angiofibroma in nasopharynx in pediatric age. To our knowledge, the case we describe is the third case of nasopharyngeal MEC in pediatric age reported in literature.
