A dermatofibroma is associated with the dimple sign; by applying lateral pressure, there is a central depression of the dermatofibroma. Although typical dermatofibromas cause little or no discomfort, itching and tenderness can occur. Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms. [5]
They can grow in all organs, arising from mesenchyme tissue. The term " fibroblastic " or "fibromatous" is used to describe tumors of the fibrous connective tissue . When the term fibroma is used without modifier, it is usually considered benign , with the term fibrosarcoma reserved for malignant tumors.
Dermatofibroma (benign fibrous histiocytoma, dermal dendrocytoma, fibrous dermatofibroma, fibrous histiocytoma, fibroma simplex, histiocytoma, nodular subepidermal fibrosis, sclerosing hemangioma) Dermatofibrosarcoma protuberans; Desmoid tumor; Diffuse cutaneous mastocytosis; Diffuse infantile fibromatosis
Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury. Numerous tissues and organs have been induced to regenerate. Bladders have been 3D-printed in the lab since 1999.
Dermatofibrosarcoma protuberans begins as a minor firm area of skin most commonly about to 1 to 5 cm in diameter. It can resemble a bruise, birthmark, or pimple. It is a slow-growing tumor and is usually found on the torso but can occur anywhere on the body. [7] About 90% of DFSPs are low-grade sarcomas.
Removal, if desired or warranted, can be done by a dermatologist, a general practitioner, or a similarly trained professional who may use cauterization, cryosurgery, excision, laser, or surgical ligation to remove the acrochorda. [2] [10] Varied home remedies are unsupported by medical evidence. [10]
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Women during pregnancy can also present with an epulis, which will resolve after birth. Fibroepithelial polyps, pedunculated lesions of the palate beneath an upper denture, are associated with this condition. A cobble-stone appearance similar to an epulis fissuratum in a patient without dentures can be diagnostic of Crohn's disease. [8]
