Is Fibrohistiocytic cancer a tumor?
Plexiform fibrohistiocytic tumor (PFT) is a low-grade, superficial, soft tissue neoplasm with a limited but significant ability to metastasize. This type of tumor only rarely presents in the skin of the head and neck.
What is Fibrohistiocytic proliferation?
The defining histological feature of a common fibrous histiocytoma is a proliferation, in varying proportions, of spindle cells forming short intersecting fascicles and histiocyte-like cells, admixed with multinucleated giant cells, inflammatory cells, foam cells and siderophages in the dermis (Figure 1A).
Is dermatofibroma benign or malignant?
Dermatofibroma (cutaneous fibrous histiocytoma) represents a common benign mesenchymal tumor, and numerous morphological variants have been described. Some variants of dermatofibroma are characterized by an increased risk of local recurrences, and there are a few reported metastasizing cases.
How common is cellular dermatofibroma?
Dermatofibroma, also known as fibrous histiocytoma, is one of the most common cutaneous soft-tissue lesions, accounting for approximately 3% of skin lesion specimens received by dermatopathology laboratories.
What is a benign fibrous histiocytoma?
Fibrous histiocytoma is a benign soft tissue tumour that may present as a fibrous mass anywhere in the human body. The involvement of the oral cavity is extremely rare and very few cases have been reported in literature till date.
What is Dermatofibrosarcoma?
Dermatofibrosarcoma protuberans (DFSP) is a very rare type of skin cancer that begins in connective tissue cells in the middle layer of your skin (dermis). Dermatofibrosarcoma protuberans may at first appear as a bruise or scar. As it grows, lumps of tissue (protuberans) may form near the surface of the skin.
What is a dermal fibroma?
What are dermatofibromas? Dermatofibromas are small, rounded noncancerous growths on the skin. The skin has different layers, including the subcutaneous fat cells, dermis, and epidermis. When certain cells inside the second layer of skin (the dermis) overgrow, dermatofibromas can develop.
Can dermatofibroma become cancerous?
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.
Is cellular dermatofibroma benign?
Background: Cellular dermatofibromas (CDF) are an uncommon variant of benign fibrous histiocytomas with propensity to recur and rarely metastasize as well as demonstrate histologic similarities to more dangerous lesions.
Is cellular dermatofibroma malignant?
We present six cases of cellular dermatofibroma (Table 1) and argue, based on the biologic behavior of these tumors, that they are best classified as malignant in nature.
What is treatment for benign fibrous histiocytoma?
The treatment of choice for BFH is wide resection of the tumor, which results in an excellent prognosis and low recurrence rate. In agreement with cases reported in the literature, our case confirms that wide excision is adequate to prevent the recurrence of the tumor.
