Fibrous histiocytoma is the soft tissue tumor of histiocytic origin that have a variety of histological patterns. Although cases of malignant fibrous histiocytoma in the head and neck have been reported increasing frequency in recent years, they are rare conditions. We reporeted a case of malignant fibrous histiocytoma of the trachea in which the Patient had been given laryngomicrosurgical biopsy for subglottic mass. Prognosis of malignant fibrous histiocytoma, the use of radiation as primary treatment, and its role in the development of secondary primary tumors in the head and neck region are reviewed.

Malignant fibrous histiocytoma (MFH) of the spermatic cord represents an uncommon location for the most common soft tissue tumor in adults. MFH of the spermatic cord is extremely rare. No case report has been described in the Korean literature. We report a case of malignant fibrous histiocytoma, myxoid type, arising from left spermatic cord. A 77-year-old male presented with a painless left upper scrotal mass for 5 months. Simple mass excision was performed for a diagnosis. Grossly, the mass closely contacted with the left spermatic cord. Since a myxoid type of malignant fibrous histiocytoma was diagnosed from histopathological findings, left radical orchiectomy with high ligation of the spermatic cord was performed additionally. There were no evidence of local recurrence or metastasis at 6 months after surgery.

Malignant fibrous histiocytoma, a type of sarcoma, is a malignant neoplasm with uncertain origin that arises in both the soft tissues and the bone. The occurrence of primary malignant fibrous histiocytoma of the pleura is extremely rare. We report a case of a 65-year-old Korean man who is being diagnosed with primary malignant fibrous histiocytoma of the pleura.

A 1-year-old neutered male Maltese dog was presented with a mass on the upper eyelid of the left eye (OS). A pinkish and alopecic mass was located in the nasal portion of the upper eyelid of OS. The mass was firmly attached to the eyelid and round-shaped with a diameter of 11 mm. Any spread to conjunctiva was not identified. On a cytological examination, cutaneous histiocytoma was confirmed, with the presence of small lymphocytes indicating later regression stage. The patient received no treatment and complete regression of the mass was verified 2 months later. The cytological examination was helpful for the diagnosis and staging of cutaneous histiocytoma. Canine eyelid histiocytoma can regress spontaneously, and thus medical or surgical treatment for removal should be considered carefully.

Primary malignant fibrous histocytoma(MFH) of pleura is very rare. Upon microscopic examination, the tumor was characterized by storiform pattern of growth and intense, diffuse immunostaining for $\alpha$ l-antichymotripsin. We report a case of primary malignant pleural fibers histiocytoma with extension to lung, which was managed by complete excision of pleural mass and lobectomy with thoracoplasty.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life. The tumor occurs principally in one of the extremities or in the abdominal cavity or retroperitoneum, but very rarely in the heart. We report a case of M.F.H. that arose from the posterior wall of the left atrium. A 50 years old woman was presented with signs and symptoms of severe congestive heart failure. On 2-D echocardiographic exam, a huge mass was found in the left atrium. The mass was excised under open heart surgery. Histologic examination revealed that the tumor was actually a malignant fibrous histiocytoma.

We describe herein an extremely rare case of a recurrent primary pulmonary malignant fibrous histiocytoma 3 months after operation that occurred in a 55-year-old man who was treated with chemotherapy and radiotherapy successfully. Until now, 36 months later, the patient has shown no evidence of tumor recurrence. The clinical, radiographic, and pathologic features are reported here together with a brief review of the literature.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life, but it is rare in the pleura. We recently experienced a case of cytology of malignant fibrous histiocytoma in plural fluid. The smear revealed histiocytic malignant cells, spindle malignant cells and inflammatory cells. The histiocytic cells showed abundant, pale cytoplasm and ovoid, irregular eccentrically-placed nuclei. The spindle cells showed elongated nuclei. Intercellular collagen was also present.

This benign canine histiocytoma was the most common single tumor type, followed lipoma, adenoma, soft tissue sarcoma, mast cell tumor and lymphosarcoma [2]. Canine cutaneous histiocytoma (CCH) most commonly occur as solitary lesions, head and pinnae are prefermential sites, that undergo spontaneous regression. The histologic appearance varies greatly, depending on the age of the lesion and the degree of necrosis and secondary inflammation. The age-specific incidence rate for CCH drops precipitously after 3 years, although histiocytomas occur in dogs of all ages [5]. Their etiology and pathogenesis are unknown. This case reports the gross and histopathological findings of canine cutaneous histiocytoma of observed in a young dog with localized calcification of lingual muscle. (omitted)

Malignant fibrous histiocytoma(MFH) is relatively rare in the oro-maxillofacial region, particularly in the oral cavity. MFH usually arise in the extremities, the thigh being the most common site. The incidence of malignant fibrous histiocytoma in bones is rather low compared with that in soft tissues. MFH is predominant in the 40s and 50s. Histologically, the lesion are said to show high cellularity with fibrous stroma, cellular and nuclear pleomorphism, an admixture of fibroblast-like spindle cells which tend to be arranged in whorls or cartwheel or storiform patterns, rounded mononuclear cells and multinucleated giant cells. The cells frequently have abundant eosinophilic cytoplasm which has a foamy or vesicular appearance. Treatment consists of varying combinations of radiation therapy, chemotherapy, and surgery. We have observed a case of malignant fibrous histiocytoma occured in the right maxilla of 32-year-old woman.
