Malignant fibrous histiocytoma of the hypopharynx: a case report in a young adult.
This is the first case report of malignant fibrous histiocytoma of the hypopharynx in a young adult with preservation of the larynx. Although the initial histopathological diagnosis of the biopsy was benign fibrous histiocytoma, subsequent histopathological evaluation of the surgical specimen was malignant fibrous histiocytoma. Thereafter, re-excision of the histiocytoma with a wide margin was performed coupled with reconstruction of the hypopharynx while preserving the larynx. We also report the good long-term survival of this case of low-grade type of malignant fibrous histiocytoma.
