Abstract:
Fibrous histiocytoma composed of fibroblasts and histiocytes is quite variable in histologic pattern. The biologic behavior is unpredictable by histologic ground. This tumor is well-known in subcutaneous tissue and deep soft tissue, but quite rare in central nervous system. We experienced a case of the fibrous histiocytoma involving the dura mater of spinal cord in a 26 year old female patient. In gross findings, the mass was a well demarcated, ovoid mass attached to the dura matter, and measured 2.5x1.5 cm in diameter. The cut surface was rubbery, solid, gray-white or yellow. Microscopically, the lesion consisted of polyhedral cells with round or oval nuclei and faintly eosinophilic or vaculoated cytoplasm, and multinucleated giant cells. Some giant cells were Touton-type. Composing cells were bland-looking. Mitotic figures were average 3 per 10 high power fields.
