Dermatofibroma
☆ Alemaniako Stiftung Warentest-en 2022ko emaitzetan, ModelDerm-ekin kontsumitzaileen gogobetetasuna apur bat txikiagoa izan zen ordaindutako telemedikuntzako kontsultekin baino.
Dermatofibromaren kasu tipikoa ― Nodulu gogor bat gorputz-adarrean. Dermatofibroma nahiko ohikoa den tumore onbera da.

Dermatofibroma gehienbat besoetan edo hanketan aurkitzen den azaleko gaixotasun arrunta da. Azalaren azpian pikor sendo gisa agertzen da, askotan zentimetro 1 baino gutxiagokoa. Normalean minik gabekoa izan arren, iraganeko lesio txikiekin lotuta egon daiteke, esaterako, intsektuen ziztadak edo arantza-zuloak. Dermatofibromak edonori eragin diezaioke, baina ohikoagoak dira 20 eta 40 urte bitarteko emakumezkoetan. Normalean onberak dira, baina batzuetan kendu ondoren itzul daitezke. Garrantzitsua da dermatofibromak dermatofibrosarcoma protuberans izeneko azaleko tumore erasokorrago batetik bereiztea.
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.

Lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, and epidermoid cysts tratamendu hobetsia kentzea kirurgikoa da. Cherry angiomas and sebaceous hyperplasia laser terapiarekin edo elektrodesikazioarekin tratatzen dira. Krioterapia eta bizarra escision aukera ezagunak dira acrochordons and seborrheic keratoses -rako. Familiako medikuak lesioren bat diagnostikatzeko edo tratatzeko zalantzan jartzen badu, edo biopsiak melanoma baieztatzen badu, espezialista batengana joatea gomendatzen da.
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.

Dermatofibromak aurreko lesioen erreakzio gisa sor daitezke, hala nola intsektuen ziztadak edo arantza-zuloak. Dermatofibromak azaleko lesio onberak bezala sailkatzen dira, hau da, guztiz kaltegabeak dira, nahiz eta Dermatofibromak larruazalpeko hainbat tumorerekin nahas daitezkeen. Sarkorrak diren dermatofibroma zailak izan daitezke, histologikoki ere, tumore fibrohistozitiko gaizto arraroetatik bereiztea "dermatofibrosarcoma protuberans" bezalakoa.
○ Diagnostikoa eta Tratamendua
Gehienak onberak dira, baina lesio handiek (>5 mm) biopsia egin dezakete.
