Solitary primary nerve cell tumors of the lung are a rarity among benign neoplasms.
These tumors arise from the cells of the Schwann sheath enwrapping the nerve bundles
of the autonomic nervous system. Their content of collagenous fibers varies. X-ray
examination of a 32-year-old woman revealed a round focus in the ventral paracardial
lower area of the right lung. Bronchoscopy and computerized tomography gave no indication
of malignancy. The tumor, which originated in the middle lobe, was removed from healthy
pulmonary parenchyma and histologically proven to be a pulmonary neurilemoma. Since
its first description in 1940, only some 53 cases of pulmonary neurilemoma have been
reported in the literature.
