title: Malignant fibrous histiocytoma of the larynx.
abstract: Malignant fibrous histiocytoma of the upper respiratory tract is rare. We report a case of a glottic malignant fibrous histiocytoma in a 46-year-old man. Ultrastructural findings demonstrated that tumor cells were composed of fibroblast-like cells with abundant rough endoplasmic reticulum, histiocyte-like cells with numerous lysosomes and transitional cells with characteristics of both the fibroblast-like and histiocyte-like cells. Laryngeal microsurgery was performed as surgery and the patient has done well without recurrence to date (8 months after surgery).
