Benign fibrous histiocytoma vs dermatofibroma

Dermatofibroma (DF) also referred to as Benign Fibrous Histiocytoma, is a very common skin lesion, described as usually a single round or ovoid papule or nodule, about 0.5 to 1.0 cm in diameter, often reddish brown but sometimes has a yellowish hue Definition / general Dermatofibromas (also known as fibrous histiocytomas) are a spectrum of benign dermal based lesions with fibroblastic and histiocytic differentiation There is debate as to whether dermatofibroma is a reactive or neoplastic proces What is a dermatofibroma? A dermatofibroma is a common overgrowth of the fibrous tissue situated in the dermis (the deeper of the two main layers of the skin). It is benign (harmless) and will not turn into a cancer. Whilst dermatofibromas are harmless, they can be similar in appearance to other concerning skin tumours. It is therefore im

A dermatofibroma is a common benign fibrous nodule usually found on the skin of the lower legs. A dermatofibroma is also called a cutaneous fibrous histiocytoma. Who gets a dermatofibroma? Dermatofibromas are mostly seen in adults Dermatofibroma is a common benign tumour also known as fibrous histiocytoma. There is debate as to whether dermatofibroma has a reactive or neoplastic origin. The clinical lesion is a firm tan-brown nodule most commonly found on the legs. A number of histological variants exist

Obviously, accurate diagnosis is important, since the natural history and treatment of DFSP differs greatly from that of DF-FH Dermatofibromas may also be called benign fibrous histiocytomas.

Dermatofibroma (superficial benign fibrous histiocytoma) is a common cutaneous nodule of unknown etiology that occurs more often in women. Dermatofibroma frequently develops on the extremities.. Thirty-four cases of fibrous histiocytoma (dermatofibroma) arising on the face are reported. These neoplasms occurred frequently in females (24 female, 10 male) and showed a broad age range (12 to 85 years; mean: 43.6 years, median: 41 years) Dermatofibroma (DF) and dermatofibrosarcoma protuberans (DFSP) are dermal tumors whose histogenesis has not been well defined to date. The differential diagnosis in most cases is established in routine H/E sections and may be confirmed by immunohistochemistry, but there are atypical variants of DF with less clear histological differences and non-conclusive immunohistochemical results An atrophic dermatofibroma—a variant of a dermatofibroma—is an uncommon benign fibrohistiocytic tumor that usually presents in adults as an asymptomatic depressed plaque [1,2,3,4].A comprehensive review of the literature was performed using the PubMed database to search the words: atrophic dermatofibroma; the relevant papers and their references generated by the search were reviewed

Dermatofibroma (cutaneous fibrous histiocytoma

BACKGROUND: Dermatofibroma (DF) is a superficial form of benign fibrous histiocytoma, composed of a mixture of fibroblastic cells and histiocytic cells. The histogenesis of this lesion is a matter of controversy. METHODS: Forty-five cases of DF were investigated by single and multiple immunostaining techniques, using panel of 12 antibodies. Benign Fibrous Histiocytoma is a rare tumor of mesenchymal origin. First described in 1958 by Dahlin. They are composed of two cell types, namely atypical fibroblasts and histiocytes, arranged in a storiform pattern. Lipid-filled cells may be conspicuous and occasionally are the major component Aneursymal variant of benign fibrous histiocytoma: no thick pseudocapsule, no inflammatory cells, no significant pleomorphism Angiosarcoma: endothelial tufting present, CD31+, CD34+, desmin- Additional references.

Benign Fibrous Histiocytoma: A benign tumor composed, wholly or in part, of cells with the morphologic characteristics of HISTIOCYTES and with various fibroblastic components. Fibrous histiocytomas can occur anywhere in the body. When they occur in the skin, they are called dermatofibromas or sclerosing hemangiomas. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 5th ed, p1747 INTRODUCTION. Fibrous histiocytomas are divided into two subgroups: malignant and benign fibrous histiocytomas (BFHs). BFH is one of the most common tumors of the superficial and deep soft tissues; it is commonly found on the skin and presents as a slow-growing solitary nodule made up of a mixture of fibroblastic and histiocytic cells Microscopically, aneurysmal fibrous histiocytoma can be difficult to identify, as the lesion will display some similarities to a classic dermatofibroma along with distinguishing characteristics, like large blood-filled cavernous spaces. Aneurysmal fibrous histiocytoma is a benign lesion with a low risk for recurrence if adequately excised Dermatofibroma is a condition wherein benign growths develop on the skin tissue. These growths are tender to the touch and appear singularly or in groups and linger for long periods of time. The fibrous skin growths sometimes occur right where an insect bite is found. They commonly appear on the arms and legs

Epithelioid fibrous histiocytoma (EFH) is a rare lesion believed to arise from dermal microvascular unit fibroblasts and dendritic histiocytes. EFH has long been considered a morphologic variant of benign fibrous histiocytoma (dermatofibroma), with prominent epithelioid cytomorphology that can mimic both vascular and melanocytic neoplasms Aneurysmal dermatofibroma is a rare variant of cutaneous fibrous histiocytoma (dermatofibroma) thought to be secondary to slow extravasation of blood into the lesion. The resulting entities have different clinical and pathological presentations that can lead to diagnostic confusion with other types of skin lesions. We discuss the defining features of aneurysmal dermatofibroma to outline.

A benign tumor composed, wholly or in part, of cells with the morphologic characteristics of HISTIOCYTES and with various fibroblastic components. Fibrous histiocytomas can occur anywhere in the body. When they occur in the skin, they are called dermatofibromas or sclerosing hemangiomas AFH is also known as dermatofibroma with monster cells (2) or atypical benign fibrous histiocytoma (3). This neoplasm is characterized by a relatively benign clinical course despite having pseudosarcomatous histological features (1-3); however, in comparison with FH, recurrence of AFH is common, although metastases are rare (4)
