Overview

Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms.

Physical Examination

Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms. A dermatofibroma is associated with the dimple sign; by applying lateral pressure, there is a central depression of the dermatofibroma.

Extremities

• Hard papules (rounded bumps) that may appear in a variety of colors, usually brownish to tan.
  • Especially found on the legs.

Skin

• Skin examination of patients with dermatofibroma may show:
  • Nodule with 0.3 to 1 cm in diameter
    • Note : Gient (> 5 cm) are also reported.
  • non-tender nodule
    • Note: Manipulation can cause tenderness
  • Hyperpigmentation
  • Dimple sign ( lateral compression on the skin makes a depression)
    • Note: Dimple sign can also seen in other skin diseases.
  • Puritic nodule ( may happen by superinfection)

Extremities

• Extremities examination of patients with [disease name] is usually normal.

OR

• Clubbing
• Cyanosis
• Pitting/non-pitting edema of the upper/lower extremities
• Muscle atrophy
• Fasciculations in the upper/lower extremity
