We report two cases of malignant schwannoma of skin in association with non-familial neurofibromatosis. Case 1, a 47 year old man, had a large subcutaneous tumor on the sacral area and case 2, a 62 year old woman, a painful, ulcerating tumor on the posterior aspect of the left arm. Both cases were histopathologically confirmed as malignant schwannomas and immunohistochemical studies showed S-100 protein in the tumor cells. After surgical excision of the tumors, case 1 was lost to follow up, while case 2 remained without evidence of disease for more than one and half years.
