Popis: A case of malignant shwannoma is reported with unusual elements in an 89-year-old female. A large mass was located in the subcutaneous tissue of the right lateral chest wall and measured 5 cm in the greatest diameter. Histologically the tumor was composed of neurofibroma and malignant schwannoma with glandular differentiation. Neurofibroma characterized by numerous hyaline neural nodules was located in the peripheral portion of the tumor, whereas malignant schwannoma occupied a large part of the central portion of the tumor. The glandular elements observed in some areas of malignant schwannoma consisted of cuboidal and columnar shaped cells and were arranged in tubular or tubulo-medullary fashion in which rosettes or pseudorosettes were found. Mucicarminophilic material was observed, both in the cytoplasm and in the lumen. Seven reported cases of peripheral nerve tumor with glandular differentiation are reviewed briefly.
