Dermatofibroma é uma doença de pele comum encontrada principalmente nos braços ou pernas. Aparece como caroços firmes sob a pele, geralmente com menos de 1 centímetro de tamanho. Embora geralmente seja indolor, pode estar relacionado a ferimentos leves passados, como picadas de insetos ou espinhos. Os dermatofibromas podem afetar qualquer pessoa, mas são mais comuns em mulheres entre 20 e 40 anos. Geralmente são benignos, mas às vezes podem reaparecer após a remoção. É importante diferenciar os dermatofibromas de um tumor de pele mais agressivo chamado 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.

O tratamento preferido para lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, and epidermoid cysts é a remoção cirúrgica. Cherry angiomas and sebaceous hyperplasia são comumente tratados com terapia a laser ou eletrodissecação. A crioterapia e a excisão de barbear são escolhas populares para acrochordons and seborrheic keratoses. Se um médico de família não tiver certeza sobre o diagnóstico ou tratamento de uma lesão, ou se uma biópsia confirmar melanoma, recomenda-se o encaminhamento a um especialista.

Dermatofibromas podem ser formados como reação a lesões anteriores, como picadas de insetos ou espinhos. Os dermatofibromas são classificados como lesões cutâneas benignas, o que significa que são completamente inofensivos, embora os dermatofibromas possam ser confundidos com uma variedade de tumores subcutâneos. Dermatofibromas penetrantes profundos podem ser difíceis de distinguir, mesmo histologicamente, de tumores fibrohistocíticos malignos raros como o "dermatofibrossarcoma protuberans".
○ Diagnóstico e Tratamento
A maioria é benigna, mas lesões grandes (>5 mm) podem necessitar de biópsia.
