Triton Tumor

Gross section of a Middle-aged male patient's leg presented with slowly growing mass. Below the knee amputation shows a soft tissue mass. Microscopy reveals a high grade neoplasm with divergent differentiation, suggestive of “triton tumor”; a relatively rare, aggressive tumor made up of both malignant schwannoma cells and malignant rhabdomyoblasts. It's classified as a malignant peripheral nerve sheath tumor with rhabdomyosarcomatous differentiation. The unusual name "triton" was first used in reference to observation of supernumerary limbs containing bone and muscle growing on the backs of triton salamanders after the implantation of sciatic nerve tissue.
