Malignant schwannoma of the liver in a patient without neurofibromatosis: a case report and review of the literature.

Primary schwannomas of the liver are extremely rare. We report a case of malignant schwannoma of the liver occurring in a 49-year-old man, who did not have neurofibromatosis, and review the literature. The clinical and histologic findings of benign and malignant schwannomas of the liver are compared.
