Dermatofibroma - Dermatofibrom
☆ I 2022 Stiftung Warentest-resultatene fra Tyskland var forbrukertilfredsheten med ModelDerm bare litt lavere enn med betalte telemedisinkonsultasjoner.
Typisk tilfelle av Dermatofibrom (Dermatofibroma) ― En hard knute på lemmen. Dermatofibrom (Dermatofibroma) er en relativt vanlig godartet svulst.

Dermatofibroma er en vanlig hudtilstand som hovedsakelig finnes på armer eller ben. Det vises som faste klumper under huden, ofte mindre enn 1 centimeter i størrelse. Selv om det vanligvis er smertefritt, kan det være knyttet til tidligere mindre skader som insektbitt eller tornstikk. Dermatofibromer kan påvirke alle, men er mer vanlig hos kvinner i alderen 20 til 40. De er vanligvis godartede, men noen ganger kan de komme tilbake etter fjerning. Det er viktig å skille dermatofibromer fra en mer aggressiv hudsvulst kalt 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.

Den foretrukne behandlingen for lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts er kirurgisk fjerning. Cherry angiomas, sebaceous hyperplasia behandles vanligvis med laserterapi eller elektrodesikasjon. Kryoterapi og barbering er populære valg for acrochordons, seborrheic keratoses. Hvis en familielege føler seg usikker på diagnostisering eller behandling av en lesjon, eller hvis en biopsi bekrefter melanom, anbefales henvisning til en spesialist.
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.

Dermatofibromer kan dannes som en reaksjon på tidligere skader som insektbitt eller tornestikk. Dermatofibromer er klassifisert som godartede hudlesjoner, noe som betyr at de er helt ufarlige, selv om dermatofibromer kan forveksles med en rekke subkutane svulster. Dypt penetrerende dermatofibromer kan være vanskelig å skille, selv histologisk, fra sjeldne ondartede fibrohistocytiske svulster som "dermatofibrosarcoma protuberans".
○ Diagnose og behandling
De fleste er godartede, men store lesjoner (>5 mm) kan kreve biopsi.
