See also granuloma annulare.
Nodular, subcutaneous or deep granuloma annulare (GA) is an uncommon variant that most commonly occurs on the extremities and scalp of children.
Asymptomatic dermal or subcutaneous nodules are seen. Rarely, sterile prurient drainage may occur. The extremities are most commonly affected, but lesions in the scalp may also be seen. In a variant affecting young women, the lesions are about joints and the term juxta-articular granuloma annulare has been suggested [Am J Dermatopathol 2005:27:1-5].
Cutaneous nodules with granulomatous inflammation on biopsy brings up a large list of possibilities, including infection, cutaneous Crohn's disease, and rheumatoid nodules.
No treatment is needed. They tend to resolve spontaneously over 1-4 years. IL steroid may be done.
