ReferencesDermatofibroma on yleinen ihosairaus, jota esiintyy enimmäkseen käsissä tai jaloissa. Se näyttää kiinteiltä kyhmyiltä ihon alla, usein alle 1 senttimetrin kokoisina. Vaikka se on yleensä kivuton, se voi liittyä menneisiin pieniin vammoihin, kuten hyönteisten puremiin tai piikkipistoihin. Dermatofibromat (Dermatofibromas) voivat esiintyä kenellä tahansa, mutta ne ovat yleisempiä 20–40‑vuotiailla naisilla. Ne ovat tyypillisesti hyvänlaatuisia, mutta joskus ne voivat palata poiston jälkeen. On tärkeää erottaa dermatofibromat (Dermatofibromas) aggressiivisemmasta ihokasvaimesta nimeltä dermatofibrosarcoma protuberans.
Dermatofibroma is a commonly occurring cutaneous entity usually centered within the skin's dermis. Dermatofibromas are referred to as benign fibrous histiocytomas of the skin, superficial/cutaneous benign fibrous histiocytomas, or common fibrous histiocytoma. These mesenchymal cell lesions of the dermis clinically are firm subcutaneous nodules that occur on the extremities in the vast majority of cases and may or may not be associated with overlying skin changes. They are most commonly asymptomatic and usually relatively small, less than or equal to 1 centimeter in diameter. Often, patients who present with a dermatofibroma relate a history of possibly inciting local trauma at the site, such as from an insect bite or superficial puncture wound from thorns or wood splinters. Dermatofibromas occur in people of all ages, although more commonly during the ages of the 20s to 40s, and develop more frequently in females than males, with as high as a 2:1 female to male predominance according to some reports. They are a benign tumor, although there have been cases of local recurrence, and even more rarely, distant metastases have been reported. When considering the differential diagnosis of these lesions, it is vitally important to distinguish dermatofibromas from dermatofibrosarcoma protuberans, a similar-appearing but more aggressive cutaneous neoplasm.

Suositeltu hoito lipoomat (lipomas), dermatofibroomat (dermatofibromas), keratoakanthaamot (keratoacanthomas), pyogeeniset granuloomat (pyogenic granulomas) ja epidermoidikystat (epidermoid cysts) on kirurginen poisto. Kirsikkaangiomat (Cherry angiomas) ja sebaceous hyperplasia hoidetaan yleensä laserhoidolla tai sähkökuivauksella. Kryoterapia ja parranajoleikkaus ovat suosittuja valintoja acrochordonit (acrochordons) ja seborrheic keratosit (seborrheic keratoses). Jos perhelääkäri on epävarma lesioiden diagnosoinnista tai hoidosta tai jos biopsia vahvistaa melanooman, suositellaan lähetettä erikoislääkärille.
The preferred treatment for lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts is surgical removal. Cherry angiomas, sebaceous hyperplasia are commonly treated with laser therapy or electrodesiccation. Cryotherapy and shave excision are popular choices for acrochordons, seborrheic keratoses. If a family physician feels uncertain about diagnosing or treating a lesion, or if a biopsy confirms melanoma, referral to a specialist is recommended.

Dermatofibroomat (dermatofibroma) voivat muodostua reaktiona aikaisempiin vammoihin, kuten hyönteisten puremiin tai piikkipistoihin. Dermatofibroomat (dermatofibroma) luokitellaan hyvänlaatuisiksi ihovaurioiksi, mikä tarkoittaa, että ne ovat täysin vaarattomia, vaikka dermatofibroomat (dermatofibroma) voidaan sekoittaa useisiin ihonalaisiin kasvaimiin. Syvälle tunkeutuvia dermatofibroomeja (dermatofibroma) voi olla vaikea erottaa jopa histologisesti harvinaisista pahanlaatuisista fibrohistosyyttisistä kasvaimista, kuten "dermatofibrosarcoma protuberans".
○ Diagnostiikka ja hoito
Useimmat ovat hyvänlaatuisia, mutta suuret lesioona (lesion) (> 5 mm) voivat vaatia biopsian.
