Introduction:
Malignant fibrohistiocytoma is one of the rare neoplasms of the larynx. It has nonepithelial origin. The most common sites of the neoplasm are: limbs, trunk and retroperitoneal space. Other localizations within head and neck are very rare. There are 5 histologic types. The most common is pleomorphic type. It is built of histiocytes, fibroblasts and multinuclear giant cells. An examination of the neoplasms consists of microscopic and immunohistologic examination with identification specific tissue markers and intermediate filaments of proteins. Treatment methods of the neoplasms are radical surgery, radiotherapy, chemiotherapy and associate methods of therapy. Prognosis is very bad.
Material And Methods:
[corrected] We present 71 years old man with croak for four mounths. The tumor of the larynx was examined in laryngoscopy. Biopsy of the tumor confirmed malignant fibrohistiocytoma. Laser surgery (chordectomy) was used to treatment this tumor without radiotherapy.
Results:
One year observation of the patient didn't show recurrence of neoplasm, but he had only croak.
Conclusions:
Malignant fibrohistiocytoma of the larynx doesn't differ from other malignant neoplasms of the larynx. Malignant fibrohistiocytoma of the larynx is very rare malignant neoplasms of the larynx.
