Abstract

Granuloma annulare is a non-infectious granulomatous skin condition with multiple different associations. We present a case of a man in his 60s with a three-week history of progressive targetoid plaques on his arms, legs, and trunk. Skin biopsy demonstrated interstitial granuloma annulare. Additional testing revealed IgM antibodies to Borrelia burgdorferi on western blot suggesting interstitial granuloma annulare was precipitated by the recent infection. Lyme disease is an uncommonly reported association with interstitial granuloma annulare.
