Subcutaneous Granuloma Anulare at the Orbital Rim Mimicking a Dermoid Cyst

Background

Granuloma anulare (GA) is a benign dermatologic condition of unknown etiology, named for its ringlike pattern of skin-colored nodules or papules. It is commonly affecting the skin of extremities and trunk within the first three decades of life. The histologic picture of GA is a granulomatous inflammation with histiocytes palisading around a center of necrotic collagen [1].
