Signs and symptoms

Generalized granuloma annulare is a chronic granulomatous dermatosis that typically affects young adults' distal extremities and manifests as annular grouped papules.[2] On the trunk and extremities, numerous flesh-colored papules arranged in an annular pattern are the hallmark of generalized granuloma annulare. These lesions are frequently itchy, in contrast to the traditional presentation.[3]

Causes

A variety of factors, such as infection, sun exposure, medication use, and trauma, appear to play a role in the development of the disease.[4]

Diagnosis

It has been observed that certain laboratory abnormalities exist, such as hyperlipidemia, hypergammaglobulinemia, and the presence of circulating antinuclear antibodies.[5] Histopathologic analysis may show lymphohistiocytic granuloma-related alterations primarily in the papillary and mid dermis. Palisaded or interstitial patterns, or a combination of the two, may be seen in inflammatory infiltrates.[4]

Treatment

Generalized granuloma annulare is mostly treated with

phototherapy as opposed to oral steroids, however treatment efficacy is constrained by a high rate of recurrence after stopping treatment.[6]

Epidemiology

Generalized granuloma annulare accounts for up to 15% of granuloma annulare cases.[3]
