Parapharyngeal Alveolar Soft Part Sarcoma in a 5-Year-Old Child

Alveolar soft part sarcoma (ASPS) is a rare malignancy of head and neck region; orbit and tongue being most common subsites affected by this rare tumor. A 5-year-old female presented with computed tomography scan evidence of right-sided prestyloid parapharyngeal mass. Complete excision was performed through trans-cervical approach. Histopathology, special stain, and immunohistochemistry of the resected specimen confirmed the diagnosis of ASPS. Three-year follow-up did not reveal any local recurrence or distant metastases. Review of the English-language scientific literature did not reveal any documented case of parapharyngeal space ASPS in pediatric age. Only 1 clinical report of ASPS in a 42-year-old female has been documented.
