Two patients are presented who had malignant fibrous histiocytomas of the skin and soft tissue. These tumors characteristically consist of a solitary mass, 0.5 cm to 12.0 cm, which has skin fixation, is circumscribed and firm. Microscopically, there is a pattern of histiocytes and bizarre histiocytic giant cells intermingled in a fibrous stroma with fibroblasts arranged in a whirling pattern. T...
BACKGROUND We report a case of a spray painter who developed malignant fibrous histiocytoma (MFH) of the maxillary sinus following long-term exposure to chromium, nickel, and formaldehyde, implying that these agents are probable causal agents of MFH. CASE REPORT The patient developed right-sided prosopalgia that began twenty months ago. The symptom persisted despite medical treatment. After t...
Malignant fibrous histiocytoma of the kidney is an extremely rare tumor that is thought to arise from the renal capsule. Radical nephrectomy is the standard treatment for localized disease but 25% of patients die of metastatic disease despite radical surgical resection. In the absence of clear pathogenetic information, adjuvant treatment remains empiric. Herein, we describe the case of a previo...
UNLABELLED A cell line was established from a patient with malignant fibrous histiocytoma, which had originated in the maxillary sinus. Using this cell line, sensitivity to chemotherapeutic agents and cytotoxicity against various immunoeffecter cells were tested. RESULTS This MFH cell line was sensitive in some degree to adriamycin, 5-fluorouracil, cisplatin, peplomycin, and methotrexate at h...
Sarcomatoid variant of anaplastic large cell lymphoma (ALCL) is one of the rarest histologic variants of ALCL that consists of large, bizarre, often spindle-shaped, neoplastic cells resembling a soft tissue sarcoma. We report here such a case of ALCL with both pulmonary and multiple nodal involvement in a 47-year-old woman who initially presented with fever, cough, sputum, itching skin, and wei...
The present report describes a giant cell type of malignant fibrous histiocytoma (MFH), diagnosed in soft parts of the right abdominal mammary region, in an 11-year old, 8 kg, nulliparous female Ankara (Angora) cat diagnosed in soft parts of the right abdominal mammary region. The tumor, surgically excised from the abdominal region, had a flexible consistency with ulcerated overlying skin. The ...
Primary renal malignant fibrous histiocytoma is extremely rare. The prognosis is generally poor because of the high rate of local recurrence even if radical surgery is performed. We report a case of primary renal malignant fibrous histiocytoma in a 43-year-old woman. A well-defined renal mass (10x9x7cm) with lobulated contour was revealed by abdominal ultrasonography and computerized tomography...
BACKGROUND Malignant fibrous histiocytoma is a sarcoma of uncertain origin that can be found both in soft tissues and in bones. It is currently called undifferentiated pleomorphic sarcoma not otherwise specified and it represents a final common pathway in several tumors that are subject to the progress of dedifferentiation. Local recurrence of the tumor in the same location where it was origina...
Symptomatic mitral stenosis caused by a left atrial mass as the first sign of metastasis of a malignant tumor is extremely rare and frequently associated with poor prognosis. We report a case of a 59-year-old man with a history of grade 3 malignant fibrous histiocytoma on his left tigh treated by limb-sparing surgery 17 months earlier, who was admitted with 10-days of worsening dyspnea. Imaging...
