PMID: 36051735.


Atopic dermatitis is a condition characterized by xerotic and pruritic skin. While the onset of the disease is usually in childhood, it may persist into adulthood. First-line treatments include adequate moisturization, avoidance of irritants, and the application of topical corticosteroids. Dupilumab is a biologic therapy, approved for moderate-to-severe atopic dermatitis, that dampens the pruritus sensation by inhibiting the downstream effects of the T helper cell type 2 pathway by binding to the interleukin-4 receptor α subunit. The monoclonal antibody is typically well-tolerated. We present a novel case of the development of generalized granuloma annulare after treatment with dupilumab. A 71-year-old male with a history of hypertension, hyperlipidemia, chronic kidney disease, gout, and bipolar disorder presented to clinic with biopsy-proven severe atopic dermatitis. First-line treatments had been exhausted, and the patient was not an ideal candidate for traditional systemic options secondary to his poor renal function. Therapy with dupilumab was initiated and continued for two years until the patient developed biopsy-proven generalized granuloma annulare. At this time, dupilumab was discontinued and the pharmaceutical company was made aware of this side effect.
