Dermatofibroma
☆ Tamin'ny valin'ny Stiftung Warentest 2022 avy any Alemaina, ny fahafaham-pon'ny mpanjifa amin'ny ModelDerm dia ambany kely noho ny fifampidinihana telemedicine karama.
tranga mahazatra Dermatofibroma ― Nodule mafy amin'ny rantsambatana. Dermatofibroma dia fivontosana tsy dia fahita firy.

Dermatofibroma dia aretina hoditra fahita matetika eo amin'ny tanana na tongotra. Miseho toy ny vongany mafy eo ambanin'ny hoditra izy io, matetika latsaky ny 1 santimetatra ny habeny. Na dia tsy maharary aza matetika, dia mety mifandray amin'ny ratra kely lasa toy ny kaikitry ny bibikely na tsilo. Ny dermatofibroma dia mety hisy fiantraikany amin'ny olona rehetra fa matetika kokoa amin'ny vehivavy 20 ka hatramin'ny 40 taona. Matetika izy ireo dia malemy, saingy indraindray dia afaka miverina aorian'ny fanesorana. Zava-dehibe ny manavaka ny dermatofibroma amin'ny fivontosana hoditra mahery vaika antsoina hoe 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.

Ny fitsaboana tiana ho an'ny lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts dia ny fanesorana fandidiana. Cherry angiomas, sebaceous hyperplasia dia matetika tsaboina amin'ny fitsaboana laser na electrodesiccation. Safidy malaza ho an'ny acrochordons, seborrheic keratoses ny cryotherapy sy ny excision shave. Raha misy dokotera ao amin'ny fianakaviana tsy mahazo antoka momba ny fizahana na ny fitsaboana ny ratra, na raha misy biopsy manamarina ny melanoma, dia asaina manatona manam-pahaizana manokana.
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.

Ny dermatofibroma dia mety miforona ho fanehoana ny ratra teo aloha toy ny kaikitry ny bibikely na ny tsilo. Ny dermatofibroma dia sokajiana ho fery hoditra malemy, midika izany fa tsy mampidi-doza tanteraka izy ireo, na dia mety hampifangaro amin'ny tumors subcutaneous isan-karazany aza ny Dermatofibroma. Mety ho sarotra ny manavaka ny dermatofibroma lalina, eny fa na dia ara-tantara aza, amin'ny fivontosana fibrohistocytic malemy tsy fahita firy toy ny "dermatofibrosarcoma protuberans".
○ Diagnose sy Fitsaboana
Ny ankamaroany dia malemy, fa ny ratra lehibe (> 5 mm) dia mety mitaky biopsy.
