Abstract:
Granuloma annulare (GA) is a common non-infectious granulomatous disease. Generalized GA is the second most common variant of GA. It is often associated with recalcitrant disease progression despite treatment. The lesion of generalized GA typically presents widespread papules that coalesce to form annular plaques over the whole body.We report a case of a patient with disseminated papules and coalescing annular plaques, primarily involving the intertriginous area and mimicking tinea corporis or cruris. Histopathological findings confirmed the lesion as GA. This case underscored the unusual clinical presentation of generalized GA. A case of GA localized to the intertriginous area has rarely been reported. Given the recalcitrant nature of the disease, dermatologists should consider generalized GA as a differential diagnosis in patients with an annular lesion involving the intertriginous area. Thus, we report this as an atypical case of generalized GA localized to the intertriginous area.
