A dermatofibroma, or benign fibrous histiocytomas, is a benign nodule in the skin, typically on the legs, elbows or chest of an adult. [3] It is usually painless. [3] It usually ranges from 0.2cm to 2cm in size but larger examples have been reported. [3] It typically results from mild trauma such as an insect bite. [3]
The World Health Organization in 2020 classified the fibro sarcomatous DFSP (DFSP-FS) variant (also termed dermatofibrosarcoma protuberans, fibro sarcomatous) of the dermatofibrosarcoma protuberans as a specific form of the intermediate (rarely metastasizing) fibroblastic and myofibroblastic tumors and other variants of this disorder as a specific form of the intermediate (locally aggressive ...
The term fibromatosis refers to a group of soft tissue tumors [1] which have certain characteristics in common, including absence of cytologic and clinical malignant features, a histology consistent with proliferation of well-differentiated fibroblasts, an infiltrative growth pattern, and aggressive clinical behavior with frequent local recurrence.
Nodules in skin include dermatofibroma [5] and pyogenic granuloma. [6] Nodules may form on tendons and muscles in response to injury, [ 7 ] and are frequently found on vocal cords . [ 8 ] They may occur in organs such as the lung , [ 9 ] or thyroid , [ 10 ] or be a sign in other medical conditions such as rheumatoid arthritis .
The hard fibroma (fibroma durum) consists of many fibres and few cells, e.g. in skin it is called dermatofibroma (fibroma simplex or nodulus cutaneous). [2] A special form is the keloid , which derives from hyperplastic growth of scars .
Dermatofibrosarcoma protuberans, fibrosarcomatous (DFSP-FS), also termed fibrosarcomatous dermatofibrosarcoma protuberans, is a rare type of tumor located in the dermis (i.e. layer of the skin below the epidermis). [1]
