Subcutaneous (deep) benign fibrous histiocytomas are also well documented and may have a more aggressive clinical course, as can tumors displaying cellular, aneurysmal (hemosiderotic), and atypical.. . Although most cases of fibrous histiocytoma pursue an indolent course, rare cases have been reported that show aggressive courses with metastases and fatality despite a benign pathology. Here, we present a 30-year-old man with metastatic cellular fibrous histiocytoma The diagnosis of dermatofibroma (DF), also referred to as fibrous histiocytoma, is made clinically and confirmed histologically if warranted. A patient history of a solitary, slow-growing cutaneous nodule on the extremities of young to middle-aged adults, often female, is consistent with DF. Usually these lesions are asymptomatic

Introduction. Although benign fibrous (fibroblastic, myofibroblastic) soft-tissue tumors vary widely in their biologic behavior, pathologic features, and most common anatomic locations, they can be grouped in the following four broad categories: benign fibrous proliferations, fibromatoses, fibrosarcomas, and fibrous proliferations of infancy and childhood (, 1) Benign fibrous histiocytoma (BFH) is a superficial (relative to the investing fascia of the compartmental musculature) soft tissue neoplasm comprised of bland fibroblasts arranged in a storiform pattern with variable giant cells and foamy histiocytes [ 1, 2 ]. Cutaneous BFH (aka dermatofibroma or dermal histiocytoma) arises in the dermis with.

Benign fibrous histiocytoma (BFH) of the skin, also named as dermatofibroma, is the most common soft tissue tumor. In contrast, deep BFH that occurred in subcutaneous and deep soft tissue is very rare. It is extremely rare for deep BFH reportedly occurred in the retroperitoneum, mediastinum, oral cavity, and pelvis Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma (MFH), is considered the most common type of soft tissue sarcoma.It has an aggressive biological behavior and a poor prognosis. As in the majority of the cases, UPS affects the extremities, this article focuses on musculoskeletal involvement Some authors have suggested that fibrous histiocytoma refers specifically to fibroblastic spindle cell tumors of the orbit with aggressive behavior and have advocated re-classifying more superficial, benign lesions as dermatofibromas (Tieger, Ophthal Plast Reconstr Surg. 2019)
Sir : Benign fibrous histiocytoma (dermatofibroma) is a very common skin tumour. Several distinctive variants have been described. In 1994, Calonje et al . described a variant which they called `cellular benign fibrous histiocytoma'. The main histological features in this group of tumours are high cellularity, fascicular/storiform growth pattern, limited polymorphism and myofibroblast‐like. Benign fibrous histiocytoma is an interesting and challenging entity even in its most usual, cutaneous presentation. Noncutaneous presentation is extremely limited, even more so for the mucosa of the head and neck area. We herein report such a case, describing the clinical characteristics of the lesion, complete diagnostic evaluation, management, and follow-up
Atypical fibrous histiocytoma is a distinctive variant of cutaneous fibrous histiocytoma, which is often mistaken histologically for sarcoma and which have a tendency to recur locally and a capacity to metastasize, although very rarely. We report a new case of atypical cutaneous fibrous histiocytoma in a 31-year-old man who presented with a recurrent polypoid nodule on the abdominal wall Fibrous histiocytoma is a benign tumour composed of a mixture of fibroblastic and histiocytic cells. Based on the location of this tumour, fibrous histiocytoma are usually divided into cutaneous types and those involving deep tissues. These lesions most often arise on the skin, but may rarely occur in soft deep tissues Benign fibrous histiocytoma [BFH] is the most common benign neoplasm in practically all localizations affecting the epidermis. The proliferative, atypical or borderline type is a cell-dense variant mostly growing faster and greater in size, with characteristically frequent local recurrences, reported incidence lying at 3-5%
fibrous histiocytoma; squamous metaplasis; Cutaneous fibrous histiocytoma is a benign dermal tumour composed of fibrohistiocytic cells. The principal variants are fibroblastic and histiocytic, although numerous morphological variants occur, including clear cell, atrophic, epithelioid, cellular, and finally aneurysmal fibrous histiocytoma (AFH) histiocytoma.

Lipidized FH is a subtype of FH that is relatively rarely ob-served, accounting for 2.1% of the variants of FH3. It most commonly develops in the lower limbs, so it has been previously called ankle-type FH Fibrous histiocytoma is a type of tumor that does not spread to other parts of the body. However it is a locally aggressive tumor and recurs locally even after adequate surgery. So, recurrence at the same site after inadequate surgery is almost sure shot. Thus, a wide excision of the area is.. benign fibrous histiocytoma is another superficial lesion occurring in young adults. This is centered predominantly within the dermis and generally has a more polymorphous cellular pattern including giant cells and siderophages. Moreover, it should still retain typical features of dermatofibroma, such as epiderma

Benign conditions include: periosteal desmoids, non-ossifying fibroma (fibrous cortical defect, benign fibrous histiocytoma), fibrous dysplasia, osteofibrous dysplasia, myofibromatosis, and intraosseous desmoplastic fibroma
Comment. Fibrous histiocytomas are soft tissue tumours and may be benign or malignant, the benign variety being the most common. 1 They are usually found on the extremities, but can occur in any part of the body, including orbital tissues. Fibrous histiocytomas account for 1% of all orbital tumours, and are the most common primary mesenchymal tumour of the orbit. 2 Benign fibrous histiocytomas. Benign Fibrous Histiocytoma: A benign tumor composed, wholly or in part, of cells with the morphologic characteristics of HISTIOCYTES and with various fibroblastic components.

Benign fibrous histiocytoma (BFH) is a benign fibrohistiocytic neoplasm. It is documented to occur in all anatomic sites with a strong predilection for sun exposed skin surfaces. Intra oral occurrence of BFH comprises a lesser percentage of cases with tongue being the least reported site Benign Fibrous Histiocytoma (BFH) represents a diverse group of neoplasms which exhibit both fibroblastic and histiocytic differentiation. The term Benign Fibrous Histiocytoma was first described by Stout and Lates in 1967 .BFH is a relatively common and well characterized soft tissue lesion with the majority of them affecting the skin of extremities in the early to middle adult life. Malignant Fibrous Histiocytoma (MFH; Undifferentiated Pleomorphic Sarcoma UPS) GENERAL INFORMATION Malignant Fibrous Histiocytoma was first described in the 1960s presumably derived from a mixed histiocytic and fibroblastic cellular origin but is it now believed that it is a lesion derived from fibroblast differentiation
