Multiple intercostal neurilemmomas in a Chinese woman.

Neurilemmomas are rare tumors of neural crest cell origin that occur most commonly in the head and neck region. Intercostal neurilemmomas are extremely rare and are mostly seen as solitary tumors in the posterior mediastinum. Only one case report of multiple intercostal neurilemmomas has been documented previously. In this article, we report a case of multiple intercostal neurilemmomas in a 54-year-old woman who had initially presented with progressive dull left chest pain over a 1-year period. A computed tomography scan revealed three tumors in the left thoracic cavity which were distributed as a string of beads along the third intercostal nerve. Histological and immunohistochemical testing confirmed a diagnosis of neurilemmomas. The patient underwent successful radical excision of the tumors through a thoracotomy approach, and her postoperative course was uneventful. Following the operation, she had no evidence of recurrences.
