Aspiration biopsy cytology of malignant schwannoma metastatic to the lung.
The aspiration biopsy cytologic features of a malignant schwannoma metastatic to the lung in a 39-year-old black female with von Recklinghausen's disease are reported. Cytologic features of malignant sarcomas having a spindle-cell pattern are described along with a discussion of the cytologic differential diagnosis. This is believed to be the first reported case of a malignant schwannoma involving the lung diagnosed by aspiration cytology and demonstrates the usefulness of the technique in evaluating patients with metastatic sarcomas.
