Dermatofibroma este o afecțiune comună a pielii care se găsește mai ales pe brațe sau picioare. Apare sub piele sub formă de bulgări ferme, adesea mai mici de 1 centimetru. Deși de obicei nedureroasă, poate fi legată de leziuni minore din trecut, cum ar fi mușcăturile de insecte sau înțepăturile de spini. Dermatofibroamele pot afecta pe oricine, dar sunt mai frecvente la femeile cu vârsta cuprinsă între 20 și 40 de ani. Sunt de obicei benigne, dar uneori pot reveni după îndepărtare. Este important să diferențiem dermatofibroamele de o tumoare mai agresivă a pielii numită 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.

Tratamentul preferat pentru lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, and epidermoid cysts este îndepărtarea chirurgicală. Cherry angiomas and sebaceous hyperplasia sunt tratate în mod obișnuit cu terapie cu laser sau electrodesicare. Crioterapia și excizia de bărbierit sunt alegeri populare pentru acrochordons and seborrheic keratoses. Dacă un medic de familie se simte nesigur cu privire la diagnosticarea sau tratarea unei leziuni sau dacă o biopsie confirmă melanomul, se recomandă trimiterea la un specialist.
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.

Dermatofibroamele se pot forma ca o reacție la leziuni anterioare, cum ar fi mușcăturile de insecte sau înțepăturile de spini. Dermatofibroamele sunt clasificate ca leziuni benigne ale pielii, ceea ce înseamnă că sunt complet inofensive, deși dermatofibroamele pot fi confundate cu o varietate de tumori subcutanate. Dermatofibroamele cu penetrare profundă pot fi dificil de distins, chiar și histologic, de tumorile fibrohistocitare maligne rare, cum ar fi „dermatofibrosarcomul protuberans”.
○ Diagnostic și tratament
Majoritatea sunt benigne, dar leziunile mari (>5 mm) pot necesita biopsie.
