Pediatric Soft Tissue Perineurioma in the Head and Neck.

Soft tissue type perineuriomas (STP), or Extraneural perineuriomas, are typically found in the superficial extremities or trunk of adult patients. Their incidence in the head and neck is exceptionally rare, particularly amongst the pediatric population. Since 1978, only 19 cases of pediatric STP have been reported, with only one in the neck. This case report describes the second case of STP in the neck of a child as well as reviews the current literature on pediatric STP. The pattern of patient genetic anomalies associated with the few pediatric STP cases encountered suggests an association between genetic aberrations and STP. Clinicians should be aware of STP when formulating a differential diagnosis of pediatric soft tissue masses in the head and neck despite the rarity of this tumor.
