Kikuchi-Fujimoto disease (KFD) or histiocytic necrotizing lymphadenitis is a rare and self-limiting benign disease. 1 KFD is mostly seen in young adults before the age of 30 years with a female predominance, 2 but in children, it is more common in boys. 1 KFD is typically characterized by cervical lymphadenopathy, fever, and skin rash. 3 The etiology of KFD is still unknown, and it can lead to misdiagnosis with other diseases, including lymphoma, systemic lupus erythematosus, or hematological disorders. 4 Although supportive therapy is usually enough for management of KFD, 2 the misdiagnosis can impose patients to unnecessary diagnostic procedures and treatments. In this study, we present a case of Kikuchi-Fujimoto disease that was also positive for novel coronavirus disease 2019 (COVID-19).
