Dermatofibroma es una afección cutánea común que se encuentra principalmente en los brazos o las piernas. Aparece como bultos firmes debajo de la piel, a menudo de menos de 1 centímetro de tamaño. Aunque suele ser indoloro, puede estar relacionado con lesiones menores pasadas, como picaduras de insectos o pinchazos de espinas. Los dermatofibromas pueden afectar a cualquier persona, pero son más comunes en mujeres de 20 a 40 años. Por lo general, son benignos, pero a veces pueden reaparecer después de su extirpación. Es importante diferenciar los dermatofibromas de un tumor cutáneo más agresivo llamado 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.

El tratamiento preferido para lipomas, dermatofibromas, keratoacanthomas, pyogenic granulomas, and epidermoid cysts es la extirpación quirúrgica. Cherry angiomas and sebaceous hyperplasia comúnmente se tratan con terapia con láser o electrodesecación. La crioterapia y la escisión por afeitado son opciones populares para acrochordons and seborrheic keratoses. Si un médico de familia no está seguro acerca del diagnóstico o tratamiento de una lesión, o si una biopsia confirma un melanoma, se recomienda derivarlo a un especialista.

Los dermatofibromas pueden formarse como reacción a lesiones previas, como picaduras de insectos o pinchazos de espinas. Los dermatofibromas se clasifican como lesiones cutáneas benignas, lo que significa que son completamente inofensivos, aunque los dermatofibromas pueden confundirse con una variedad de tumores subcutáneos. Los dermatofibromas de penetración profunda pueden ser difíciles de distinguir, incluso histológicamente, de tumores fibrohistocíticos malignos raros como el "dermatofibrosarcoma protuberans".
○ Diagnostico y tratamiento
La mayoría son benignos, pero las lesiones grandes (>5 mm) pueden requerir biopsia.
