Peritoneal recurrence of thymoma treated by surgery and hyperthermic intraperitoneal chemotherapy.

Thymomas are rare (1,5 cases/million) and typically occur in adults with a median age of 50 years old. Thymomas are indolent with a 10-year overall survival for resected stage II thymomas of 70%. Late relapses occur in 20% of the cases, and distant metastasis from thymoma is rare. Peritoneal recurrence of thymoma treated with surgery associated with hyperthermic intraperitoneal chemotherapy (HIPEC) has not been described in the literature. This report manages peritoneal recurrence of thymoma with HIPEC, suggesting that aggressive therapies may decrease the risk of recurrence.
