Abstract
The use of fine needle aspiration biopsy (FNAB) to diagnose lung tumors has been very successful in regard to epithelial neoplasms. However, there is much less experience in diagnosing primary and metastatic sarcomas of the lung with this technique. We describe an unusual case of malignant schwannoma metastatic to the lung diagnosed by FNAB in a young female with von Recklinghausen's disease. The usefulness of this technique and the additional aid of S-100 staining and electron microscopic studies are discussed.
