Intraosseous neurilemoma of the sternum.

Sternal benign bone tumor is uncommon. We report a very rare case of intraosseous neurilemoma in the sternum. A girl, 10 years of age, was diagnosed as having a sternal tumor. Computed tomographic scan disclosed a mushroom-shape tumor in the region from inside of the sternum to the ventral soft tissues. Surgical resection was performed. Histopathologic findings showed a typical neurilemoma with Antoni type A and B patterns. No recurrence has been found.
