Dermatofibroma
☆ Yn 'e 2022 Stiftung Warentest-resultaten út Dútslân wie de konsuminttefredenheid mei ModelDerm mar wat leger dan mei betelle telemedisynkonsultaasjes.
Typysk gefal fan Dermatofibroma ― In hurde nodule op it lid. Dermatofibroma is in relatyf gewoane goedaardige tumor.

Dermatofibroma is in gewoane hûdbetingsten dy't meast fûn wurdt op 'e earms of skonken. It ferskynt as fêste bulten ûnder de hûd, faaks minder as 1 sintimeter yn grutte. Hoewol normaal pynlik is, kin it keppele wurde oan ferline lytse ferwûnings lykas ynsektebeten of toarnprikken. Dermatofibromas kinne beynfloedzje elkenien, mar binne faker yn wyfkes aged 20 oan 40. Se binne typysk goedaardige, mar soms se kinne komme werom nei ferwidering. It is wichtich om dermatofibromas te ûnderskieden fan in mear agressive hûdtumor neamd 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.

De foarkar behanneling foar lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, epidermoid cysts is sjirurgyske ferwidering. Cherry angiomas, sebaceous hyperplasia wurde faak behannele mei laserterapy as elektrodesiccation. Kryoterapy en skearútsnijing binne populêre karren foar acrochordons, seborrheic keratoses. As in húsdokter ûnwis fielt oer diagnoaze of behanneling fan in lysjon, of as in biopsie melanoom befêstiget, wurdt ferwizing nei in spesjalist oanrikkemandearre.
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.

Dermatofibromas kinne wurde foarme as in reaksje op eardere blessueres lykas ynsektebeten of toarnprikken. Dermatofibromas wurde klassifisearre as goedaardige hûdlesjes, wat betsjut dat se folslein harmless binne, hoewol Dermatofibromas kinne betize wurde mei in ferskaat oan subkutane tumors. Djip penetrearjende dermatofibromas kinne lestich wêze om te ûnderskieden, sels histologysk, fan seldsume maligne fibrohistozytyske tumors lykas "dermatofibrosarcoma protuberans".
○ Diagnose en behanneling
De measte binne goedaardige, mar grutte lysjes (> 5 mm) kinne biopsy nedich wêze.
