09/01/2009 - "Most ordinary malignant schwannoma are located in the deep soft tissue of the proximal portions of the upper and lower extremities and trunk; to the best of our knowledge only 26 cases of malignant epithelioid schwannoma in the skin and subcutis have been described in the literature. "
10/01/2000 - "Malignant schwannomas of the head and neck are rare tumours that offer various diagnostic and therapeutic challenges encompassing the breadth of modern histupatholagy, radiology and surgery, We describe the only reported case oj a de novo malignant schwannoma affecting the lingual nerve.
