A 26-year-old female patient visited Primary Care for evaluation of a non-tender nodule on her upper arm. The lesion had been present for several years. This lesion was classified by Dermatology as a dermatofibroma. Dermatofibromas are benign nodules that occur in the dermis, often following minor injury such as a bug bite. They occur more commonly in adult females, and typically present on the lower limbs. Dermatofibromas are usually asymptomatic, although some individuals report itching. They do not require treatment unless patients are bothered by their appearance or symptoms, or if the diagnosis is uncertain. Most treatment approaches come with a risk of scarring, which should be discussed with the patient. The most efficacious treatments for dermatofibromas are excision, cryosurgery, and pulsed dye laser therapy.
