Answer

Patients with subcutaneous granuloma annulare present with a firm, nontender, flesh-colored or pinkish nodule without overlying epidermal alteration. Lesions are typically solitary but may occur in clusters. The most commonly reported site of involvement is the lower extremities (65% of cases), often on the pretibial surface. Other typical sites include the fingers and palms and the dorsa of the feet. The buttocks, forehead, and scalp are less commonly affected. Deep dermal or subcutaneous nodules on the extremities are attached to fascia and are often therefore mobile, whereas lesions on the scalp are attached to underlying periosteum and are therefore fixed or only slightly mobile.
