An ultrastructural study of angiomatoid fibrous histiocytoma. Cancer.
Of these, 176 (59.3%) patients were diagnosed with malignant fibrous histiocytoma. Dermatofibrosarcoma was the second most prevalent soft-tissue sarcoma (56 patients; 18.9%), followed by leiomyosarcoma (27 patients; 9.1%).
(5) In primary malignant GCTs, there are 2 patterns described: fibrosarcoma or malignant fibrous histiocytoma, or, in some cases, a combination of the 2 patterns.
[1] Mesenchymal retroperitoneal sarcomas constitute mainly liposarcoma (40-41%), leiomyosarcoma (28-30%), malignant fibrous histiocytoma (7-16%), and rest are others.
Other differential diagnoses include primary splenic sarcomas, including follicular dendritic cell sarcoma (12) and malignant fibrous histiocytoma. (11) While the mitotic rate in both follicular dendritic cell sarcoma and malignant fibrous histiocytoma is usually elevated, similar to the splenic tumor in this case, the spindle cells in the sarcomas are usually more diffusely pleomorphic than the focal high-grade nuclear features present in our case.
(17) The first case of laryngeal malignant fibrous histiocytoma of the giant cell type was reported by Anghelina et al in 2009.
Malignant fibrous histiocytoma (MFH) is the most common soft tissue sarcoma in adults, comprising 20% to 40% of soft tissue sarcomas.
Malignant Fibrous Histiocytoma and Liposarcoma were the commonest tumours consisting 7 each out of 35 cases.
In our study majority of cases were of Squamous cell carcinoma constituting 67.9% cases, Haemangioma 5.8% cases, chronic tonsillitis 4.8% cases, chronic inflammation 1.9% cases, squamous papilloma 2.9% cases, verrucous carcinoma, fibrolipoma, ameloblastic carcinoma, epulis and lichen planus constituting 1.9% cases each respectively and pleomorphic adenoma, adenoid cystic carcinoma, lymphangioma, basal cell carcinoma, angiofibroma, fibrous histiocytoma and NHL constituting 0.9% cases each respectively.
AFX is considered a superficial variant of malignant fibrous histiocytoma (MFH), the most common soft-tissue sarcoma of adults.
Group VI includes other connective-tissue tumours such as desmoplastic fibroma, lipoma, and benign fibrous histiocytoma. Group VII includes other tumours such as neunilemmoma and neurofibroma.
Other patterns include tumors with meningothelial-like whorls, metaplastic bone formation, and myxoid stroma; tumors resembling solitary fibrous tumor and inflammatory malignant fibrous histiocytoma; and tumors with prominent epithelioid features.
