In this issue, Wu et al1 report a 79.3% prevalence of dyslipidemia (DLP) among adults with granuloma annulare (GA) compared with a 51.9% prevalence of DLP in controls matched for age, sex, race/ethnicity, and presence of type 2 diabetes mellitus, hypothyroidism, and hypertension (P < .001). Although the cause of GA is unknown,2 the finding of DLP among so many patients comes as a surprise. Heretofore, only vague hints suggested a possible association with a lipid abnormality. Patients with generalized GA occasionally have an abnormality of glucose metabolism, microangiopathy, and microdroplet lipid deposits inside histiocytes.
