Primitive Neuroectodermal Tumor of the Vulva in an Adolescent Girl

Extraskeletal primitive neuroectodermal tumor (PNET) is rare and that affecting the female genital tract is extremely rare. We report the case of a 17-year-old girl who presented with swelling of the clitorus. She underwent excision and histopathology was PNET. She received chemotherapy and radiation and achieved complete remission. However, she relapsed locally and systemically soon, progressed and died.

[Primitive neuroectodermal tumor of the vagus nerve]

Primitive neuroectodermal tumors are a rare type of malignant neuroectodermal tumor that is very aggressive. Cervicofacial location is rare, even exceptional. We report a case of a 4-month-old male infant, referred from the pediatric clinic for severe supralaryngeal dyspnea, a firm mass under the left mandibular angle, mobile and extended to the parotid area, painful, with a curve of the left side wall of the oropharynx. Cervical computed tomodensitometry showed a well-limited mass in the carotid area, enhanced by the contrast product. A vascularized mass, which had developed at the expense of the vagus nerve, was removed surgically. Histology found a primitive neuroectodermal tumor.
