✓ A case of malignant fibrous histiocytoma arising from the meninges in a 12-year-old boy is reported. This tumor presented as an extracerebral hemorrhagic mass in the left frontal lobe without obvious invasion of the underlying brain. Histologically, a malignant tumor with the characteristic storiform pattern of malignant fibrous histiocytoma with focal areas of hemorrhage was observed. Ultrastructurally, fibroblastic cells, undifferentiated cells, histiocytic-type cells, multinucleated tumor giant cells, and xanthomatous cells were distinctly seen. The possible cell of origin of these meningeal tumors and their prognosis are discussed. The significance of considering this entity in the differential diagnosis of those tumors of the central nervous system with a spindle-cell or xanthomatous component is discussed, and the value of ultrastructural and immunocytochemical study with glial fibrillary acidic protein in the diagnosis is stressed.

✓ A case of a malignant fibrous histiocytoma (MFH) in the right temporal lobe of a 75-year-old man is reported. The tumor involved the brain and the overlying dura as one continuous mass and had undergone extensive liquefaction necrosis of its center that had a gross appearance similar to that of an abscess. The preoperative computerized tomography scan with injection of contrast material showed the lesion to have central and peripheral enhancement suggestive of metastatic tumor, glioblastoma multiforme, or abscess. Microscopically, the tumor showed the typical features of a MFH with marked acute inflammation in the areas of necrosis. No extracranial sources for this tumor were found clinically. This is the 15th reported case of MFH involving the central nervous system as a primary neoplasm and the first case with gross pathological and radiological features resembling in many respects those of an abscess.

Abstract Benign fibrous histiocytoma is a rare and usually painless oral neoplasm found in adults that may affect either soft tissue or bone typically noted in their fifth decade. This case was found in a 32 year-old Caucasian male who presented with a fairly well circumscribed unilocular radiolucent lesion extending from the mandibular right first incisor to the left first premolar and reaching the inferior mandible on a panoramic radiograph. A bony window was created and the intrabony lesion was curetted. Multiple sections revealed a cellular tumor composed of uniform spindle-shaped cells arranged in a prominent whorled or storiform pattern. Scattered xanthoma cells, multinucleated giant cells, lymphocytes, and deposits of hemosiderin were noted throughout the lesional stroma. Although malignant fibrous histiocytoma of the bone is relatively well known, benign fibrous histiocytoma of the bone is very rare. Citation Ertas U, Büyükkurt MC.

The University

Malignant fibrous histiocytoma (MFH) malignant histiocytosis (MH) are neoplasms with different histologic appearances and consequently a different putative cell of origin. Recently, the biopsy and necropsy services at the University of Pennsylvania have seen many canine soft tissue sarcomas that have the gross and histologic appearances of both MH and MFH within the same animal. A retrospective histologic evaluation of 263 cases diagnosed originally as either MH or MFH reclassified these neoplasms into 77 cases that were exclusively MH, 110 cases exclusively MFH, and 76 cases with features of both MH and MFH. Age, sex, breed predispositions, and distribution of lesions in organs were remarkably similar between the two categories. The hybrid neoplasms containing MH-like and MFH-like regions may be the result of divergent or convergent phenotypic differentiation.

A 25-year-old female presented with symptoms resembling those of critical mitral stenosis. Echocardiography revealed a left atrial mass without a stalk, which was suspected to be a left atrial myxoma. An irregular soft friable mass was found at surgery. It measured 10 × 8 cm, with finger-like extensions and occupied almost the entire left atrial cavity, extending into the three tributaries of the right pulmonary vein. Histopathology of the excised tumor including electron microscopy showed a pleomorphic cytology interlaced with bundles, areas of necrosis, and occasional bizarre tumor giant cells. Characteristic histiocytes containing lysosomes identified the tumor as malignant fibrous histiocytoma. A postoperative course of radiotherapy with a dose of 4,000 cGy/20 fractions was applied to the mediastinum. At follow-up 4 months later the patient was asymptomatic. This case is reported because of the extreme rarity of left atrial malignant fibrous histiocytoma.

In this report, a case of malignant fibrous histiocytoma in a budgerigar (Melopsittacus undulatus) is described. At necropsy, a tumorous subcutaneous mass was noted to be located under the right wing at the level of humerus in a budgerigar. On microscopic examination, the tumor was composed of pleomorphic cells having mostly round to oval large nucleus. Presence of occasional bands composed of fibroblastoid cells were noted. Occasional giant cells and mitotic figures were also observed. Based on the microscopic findings, a diagnosis of malignant fibrous histiocytoma was made. The present case in an exotic bird was found to be interesting, since malignant fibrous histiocytomas are rare tumors of domestic animals and mostly seen in dogs.

Cellular Types

A soft tissue malignant fibrous histiocytoma was studied by light and electron microscopy. The presence of fibroblast-like cells, histiocyte-like cells, undifferentiated stem cells, and xanthomatous cells was confirmed. Fibroblast- and histiocyte-like multinucleated giant cells were also observed. The observation of lysosomes in some fibroblast-like cells, the features of undifferentiated stem cells, and the presence of cells with intermediate characteristics common to xanthomatous, histiocytic, and stem cells suggest a strict relationship among these cellular types.

A subcutaneous extraskeletal giant cell tumor (malignant fibrous histiocytoma) was excised repeatedly from a 9-year-old Domestic Shorthair cat. Ultrastructurally, the mass was composed of fibroblast-like, histiocyte-like, and multinucleated giant cells, and some undifferentiated cells and mononuclear cells intermediate between the fibroblast-like and histiocyte-like cells. Fibroblast-like cells were characterized by abundant well-developed rough endoplasmic reticulum, relatively smooth cytoplasmic membranes, few lysosomal structures, and finely granular chromatin. Histiocyte-like cells resembled immature macrophages. The cell membranes had many villous projections. Rough endoplasmic reticulum varied in quantity. Lysosomes were numerous. Multinucleated giant cells had characteristics of both the fibroblast-like and histiocyte-like cells. No viral particles were seen.
