title: Granuloma annulare mimicking multicentric reticulohistiocytosis.
abstract: We describe a patient with granuloma annulare (GA) who presented with firm periungual papules mimicking "coral beads", a characteristic sign of multicentric reticulohistiocytosis (MRH). We highlight the importance of distinguishing between GA and MRH because the prognoses differ significantly.
