[Three cases with a mediastinal neurinoma developed in a same family]

A 47-years-old woman (case 1) was admitted to our hospital because of a mediastinal mass. We performed an operation by VATS under the diagnosis of a mediastinal neurinoma. The histology of it was a neurinoma. Her father (case 2) had undergone a resection of a mediastinal neurinoma at the age of 42. Her brother (case 3) also had undergone a resection of mediastinal and intrathoracic neurinomas at the age of 37. A few years later, he underwent operations for neurinomas in limbs 2 times. We suppose patients with a mediastinal neurinoma have little complaints in many cases, so there are a number of patients who have a mediastinal neurinoma without being discovered and treated. Although the neurinoma is not considered as a hereditary disease inherently, the cases, we experienced, might have some genetic disorders. In this concern, our cases are very rare and have a great interest.
