[Multiple synchronous intrathoracic neurilemmomas who had a past history of neurilemmoma on the abdominal wall; report of a case].

A 66-year-old female, who had received a surgery of the neurilemmoma on the abdominal wall 6 years ago, was referred to our hospital because of a chest X-ray abnormality. Chest computed tomography (CT) revealed 3 tumors in the left chest wall. One tumor arised from the 7th intercostal nerve and 2 tumors from 8th nerve. These tumors were surgically removed by video-assisted thoracic surgery. These tumors are histopathologically diagnosed as neurilemmoma and have the same characteristics with previously resected abdominal wall tumor.
