Dermatofibroma - Dermatofibroom
☆ Saksamaa 2022. aasta Stiftung Warentesti tulemustes oli tarbijate rahulolu ModelDermiga vaid veidi madalam kui tasuliste telemeditsiini konsultatsioonidega.
Tüüpiline Dermatofibroom (Dermatofibroma) juhtum — kõva sõlm jäsemes. Dermatofibroom (Dermatofibroma) on suhteliselt levinud healoomuline kasvaja.

ReferencesDermatofibroma on tavaline nahahaigus, mis esineb enamasti kätel või jalgadel. See ilmub naha all kindlate tükkidena, mille suurus on sageli alla 1 cm. Kuigi see on tavaliselt valutu, võib see olla seotud varasemate väiksemate vigastustega, näiteks putukahammustuste või okkadega. Dermatofibroomid võivad esineda kõigil, kuid neid täheldatakse sagedamini 20–40‑aastastel naistel. Tavaliselt on need healoomulised, kuid mõnikord võivad need pärast eemaldamist taastuda. Oluline on eristada dermatofibroomi agressiivsemast nahakasvajast nimega 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.

Lipoomide (lipomas), dermatofibroomide (dermatofibromas), keratoakantomide (keratoacanthomas), pyogeensete granuloomide (pyogenic granulomas) ja epidermoidsete tsüstide (epidermoid cysts) eelistatud ravi on kirurgiline eemaldamine. Kirsikangiome (Cherry angiomas) ja sebase hüperplaasiat (sebaceous hyperplasia) ravitakse tavaliselt laserteraapia või elektrodesikatsiooniga. Krüoteraapia ja raseerimisega eemaldamine on akrokordoonide (acrochordons) ja seboreaatsete keratoseide (seborrheic keratoses) populaarsed valikud. Kui perearst tunneb kahjustuse diagnoosimise või ravi osas ebakindlust või kui biopsia kinnitab melanoomi, on soovitatav pöörduda eriarsti vastuvõtule.
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.

Dermatofibroomid võivad tekkida reaktsioonina varasematele vigastustele, nagu putukahammustused või okkatorked. Dermatofibroomid klassifitseeritakse healoomulisteks nahakahjustusteks, mis tähendab, et need on täiesti kahjutud, kuigi dermatofibroomi võib segi ajada mitmesuguste nahaaluste kasvajatega. Sügavalt tungivaid dermatofibroome võib olla raske isegi histoloogiliselt eristada harvaesinevatest pahaloomulistest fibrohistotsüütilistest kasvajatest, nagu dermatofibrosarcoma protuberans.
○ Diagnostika ja ravi
Enamik neist on healoomulised, kuid suured kahjustused (>5 mm) võivad vajada biopsiat.
