Dimple sign, also known as Fitzpatrick’s sign, is a clinical feature used in diagnosing dermatofibromas. Lateral compression with the thumb and index finger leads to depression of the lesion. This dimpling effect is secondary to the lesion being attached to the subcutaneous fat. The sign may be useful in differentiating dermatofibromas

dimple sign A clinical finding evoked by pinching a subcutaneous lesion, which results in a central dell/dimple, seen in well-circumscribed, often benign superficial dermal tumors–eg, dermatofibromas, inclusion cysts, lipomas, neurofibromas.

2024年4月25日 · A dermatofibroma may form a small dimple in the middle when you pinch it. This is called the “dimple sign.” Main symptoms. Firm raised papule; 5mm to 1cm diameter; Pink, tan, or brown; Painless, but may itch or feel irritating; May have a dimple sign when squeezed
