A rare Encounter with Pediatric Malignant Peripheral Nerve Sheath Tumor in Nasal Sinuses and Orbit

AbstractThis case report explores a rare and aggressive Malignant Peripheral Nerve Sheath Tumor (MPNST) in a 7-year-old child affecting nasal sinuses, maxilla, and orbit, an exceptionally uncommon pediatric manifestation unrelated to Neurofibromatosis 1. The child presented with alarming symptoms —nasal obstruction, snoring, epistaxis, and difficulty swallowing—underscoring the case’s urgency. Non-contrast computed tomography revealed an extensive mass infiltrating nasopharynx, nasal cavity, maxillary sinus, ethmoid sinuses, and orbit, causing destructive consequences. Histopathology c onfirmed a high-grade MPNST, marked by rapid growth and early metastasis, highlighting management challenges. The rarity of pediatric MPNST in the nasal cavity is discussed, emphasizing the need for a broad differential diagnosis. Treatment involves surgical resection and adjuvant chemoradiation wit h a grim prognosis due to diagnostic complexities and morphological mimicry in young patients.
