Dermatology - Dermatofibroma 
Dermatofibromas are prevalent cutaneous nodules that resemble buttons and typically appear on the limbs. They hold significance solely due to their aesthetic appeal or the potential confusion they may cause as colored growths.

The lesions develop gradually over a span of several months and remain unchanged in size for several years. They may also exhibit spontaneous regression.

These nodules are without symptoms, measuring 3–10 mm in diameter and exhibiting varying colors. The nodule exhibits a convex shape, although occasionally it is also concave in relation to the adjacent skin. The surface can exhibit a lackluster, glossy, or rough texture, potentially appearing scaly or encrusted. Lateral compression results in the formation of a "dimple," which may occasionally be sensitive to touch.

The diagnosis is based only on clinical observations and assessments.
Therapy is unnecessary as removal results in the formation of scars. Cryosurgery with a cotton tip applicator results in a scar that is often more satisfactory, but often requires multiple treatments.
