Radical resection and improvised surgical reconstruction for a rare malignant triton tumour of intercostal nerve in a patient with neurofibromatosis type 1

A man aged 28 years, with neurofibromatosis type 1, presented with abdominal pain and visible right lower chest swelling. He had cutaneous neurofibromas and several café-au-lait spots. CT scan of the chest and abdomen revealed a giant mass most likely originating from the right 7th intercostal nerve, extending downwards into the abdomen causing massive hepatic compression. A Trucut biopsy showed malignant peripheral nerve sheath tumour. Radical surgical resection with wide margins was performed. The chest wall and diaphragm were reconstructed with improvised surgical technique with excellent results. Final histopathology report revealed a triton tumour of the intercostal nerve.
