Unilateral Palmar Post-traumatic Granuloma Annulare – Work-related?

Open access


Granuloma annulare (GA) is a granulomatous skin condition that can present with a diversity of clinical manifestations and locations, with an unknown etiology and diagnosed on clinical-pathological grounds/correlations. Although many trigger factors have been described and several pathogenic mechanisms proposed, the etiology of GA remains unknown. We report a case of work-related, isolated, unilateral GA localized on the right palmar area of a young worker, possibly induced by work-related direct trauma.
