Dermatofibroma - Dermatofibróm
☆ Vo výsledkoch Stiftung Warentest z Nemecka za rok 2022 bola spokojnosť spotrebiteľov s ModelDerm len o niečo nižšia ako s platenými telemedicínskymi konzultáciami.
Typický prípad Dermatofibróm (Dermatofibroma) ― Tvrdý uzlík na končatine. Dermatofibróm (Dermatofibroma) je pomerne bežný benígny nádor.

Dermatofibroma je bežné ochorenie kože, ktoré sa vyskytuje väčšinou na rukách alebo nohách. Prejavuje sa ako pevné hrčky pod kožou, často menšie ako 1 centimeter. Aj keď je to zvyčajne bezbolestné, môže to súvisieť s predchádzajúcimi menšími zraneniami, ako sú uhryznutie hmyzom alebo bodnutie tŕňmi. Dermatofibrómy môžu postihnúť kohokoľvek, ale sú bežnejšie u žien vo veku 20 až 40 rokov. Zvyčajne sú benígne, ale niekedy sa môžu po odstránení vrátiť. Je dôležité odlíšiť dermatofibrómy od agresívnejšieho kožného nádoru nazývaného 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.

Preferovanou liečbou lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, and epidermoid cysts je chirurgické odstránenie. Cherry angiomas and sebaceous hyperplasia sa bežne liečia laserovou terapiou alebo elektrodesikáciou. Kryoterapia a excízia holenia sú populárnou voľbou pre acrochordons and seborrheic keratoses. Ak si rodinný lekár nie je istý diagnostikovaním alebo liečbou lézie, alebo ak biopsia potvrdí melanóm, odporúča sa obrátiť sa na špecialistu.
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.

Dermatofibrómy sa môžu vytvoriť ako reakcia na predchádzajúce zranenia, ako je uhryznutie hmyzom alebo bodnutie tŕňmi. Dermatofibrómy sú klasifikované ako benígne kožné lézie, čo znamená, že sú úplne neškodné, hoci dermatofibrómy sa môžu zamieňať s rôznymi subkutánnymi nádormi. Hlboko prenikajúce dermatofibrómy môže byť ťažké odlíšiť, dokonca aj histologicky, od zriedkavých malígnych fibrohistocytických nádorov, ako je "dermatofibrosarcoma protuberans".
○ Diagnostika a liečba
Väčšina z nich je benígna, ale veľké lézie (> 5 mm) môžu vyžadovať biopsiu.
