To our knowledge, an acute-onset, painful acral eruption has not been previously recognized. Observations: We report 4 patients who presented with acute onset, painful acral granuloma annulare. Conclusions: It is possible for granuloma annulare to present as a painful eruption with an acute onset and an acral distribution. Biopsy results are a crucial factor when establishing the diagnosis of this atypical clinical presentation of granuloma annulare.展开更多
