[Primary multiple neurilemmoma of the diaphragm].

Primary tumor of the diaphragm is very rare. Furthermore, to our knowledge, no cases of multiple neurilemmoma of the diaphragm have appeared in the literature. A 61-year-old female was admitted to our hospital because of epigastric discomfort. Roentgenologic examination of the chest showed a tumor in the left leaf of the diaphragm. Laparotomy revealed two tumors, one measuring about 5 cm in diameter, and the other about 1 cm in diameter arising from the diaphragm. There was no adhesion to adjacent organs. The two tumors were resected with a part of the left diaphragm. Histological examination revealed benign neurilemmoma of the diaphragm. There has been follow-up on the patient for two and a half years without evidence of recurrence.
