[An exceptional but serious complication of benign intercostal schwannoma: hemothorax].

Spontaneous serious hemothorax has not been described previously as an inaugural signor secondary complication of benign intercostal schwannoma. We report a case in a 45-year-old woman who was hospitalized in an emergency setting after development of massive left hemothorax. After evacuation of the effusion, imaging demonstrated a voluminous apparently neurogenic tumor in an intercostal position. Thoracotomy was required for hemostasis due to persistent bleeding. Tumor resection was performed. At histology, the surgical specimen was found to be a benign schwannoma presenting hemorrhagic remodeling. Resection provided complete cure with no sequelae. This secondary complication favors resection of benign intercostal schwannoma.
