A case of left brachial plexus‐related malignant peripheral nerve sheath tumor showing neoplastic, glandular, and rhabdomyoblastic elements in a 39‐year‐old Chinese man is reported. The authors suggested that this tumor be termed a malignant glandular triton tumor in view of the presence of the adenocarcinomatous component. The patient had extensive local recurrence comprising mainly the Schwann spindle cells within a year after complete piecemeal removal and died 15 months later after the initial presentation. The natural behavior of this tumor, as in other reported cases of malignant triton tumor, is extremely aggressive, unlike malignant schwannoma or glandular malignant schwannoma. The histogenesis of this tumor is likely to be from primitive neural crest cells, Schwann's cell precursors, or metaplastic malignant Schwann's cells.
