Analysis of two cases with bronchopulmonary neurofibromatosis.

Neurogenic tumor of lung is very rare. Only few cases have been reported in the literature. We present here two cases of bronchopulmonary neurofibromatosis in two adults. In both cases, attempts at imaging failed to diagnose the case, and it was the histological study that ensured the diagnosis of neurofibromatosis. Biopsy specimens showed bundles of spindle-shaped cells mixed with collagen, and on immunohistochemistry some cells were positive for S-100 protein.
