Abstract
Cutaneous Rosai-Dorfman disease (CRDD) is a rare form of non-Langerhans cell histiocytosis. Because the etiology and pathogenesis remain unclear and the cutaneous manifestations are highly variable, no definitive diagnostic criteria have been established. As a result, the risk of diagnostic errors and missed diagnoses is common in clinical practice. This report describes the case of a 64-year-old woman with facial CRDD that initially misdiagnosed as sporotrichosis. This case broadens the known clinical spectrum of CRDD and underscores the importance of careful differential diagnosis to avoid misdiagnosis and ensure appropriate treatment.
