Dermatofibromas are discrete firm dermal papules, 3-7 mm in diameter. Most dermatofibromas are dome shaped, although some are depressed below the surrounding skin surface. Dermatofibromas are typically flesh colored to pink with a poorly defined rim of tan to brown pigmentation. Lesions larger than 3.0 cm are occasionally seen. These larger lesions can be worrisome and may require a biopsy for definitive diagnosis. Dermatofibromas should be stable in size, appearance, and color. If they are not, they should be biopsied to confirm their benign nature.
