Abstract Malignant triton tumor (MTT) is a rare subtype of malignant peripheral nerve sheath tumors with rhabdomyoblastic differentiation. Although the condition may manifest sporadically, it typically affects adult patients with neurofibromatosis type 1. In this article, an extremely rare case of MTT with chest wall origin, which expanded into the left thoracic cavity, is reported. A 64-year-old male was admitted to the institution with sudden shortness of breath. Radiological examination revealed a large mass with massive pleural effusion occupying the patient’s left hemithorax. A percutaneous needle biopsy was performed and the patient underwent subtotal tumor resection with left pleuropneumonectomy. Immunohistochemical study of postsurgical pathologic specimens confirmed the diagnosis of MTT. Despite extensive surgical removal, tumor recurrence was reported soon after resection, leading to patient’s death 20 days after surgery due to acute respiratory failure. Investigation of rare MTT cases is necessary for understanding this condition.

Abstract Malignant peripheral nerve sheath tumors arise from Schwann cells or within existing neurofibromas and have a strong association with type 1 neurofibromatosis. These tumors are histologically diverse and may contain malignant areas of divergent mesenchymal differentiation, the most common of which is skeletal muscle (rhabdomyosarcoma). Malignant peripheral nerve sheath tumor with rhabdomyosarcomatous differentiation is also known as malignant triton tumor. Malignant triton tumor has a worse prognosis than classic malignant peripheral nerve sheath tumor does, and the correct diagnosis requires attention to the clinical history and knowledge of the complexities regarding its differential diagnosis. In this review we discuss the clinical, histopathological, immunohistochemical, and prognostic features of this rare neoplasm.
