Disseminated Kikuchi-Fujimoto disease mimicking malignant lymphoma on positron emission tomography in a child.
Kikuchi-Fujimoto disease is a rare and benign disease, characterized by regional cervical lymphadenopathy with fever of unknown origin, affecting mainly young women. This self-limiting disease of unknown etiology has rarely been reported in children, so it has been frequently confused with malignancies. We describe a case of a child who was initially mistaken for malignant lymphoma because of multiple lymph nodes with 18-fluorodeoxyglucose uptake on positron emission tomography and was finally diagnosed with Kikuchi-Fujimoto disease by excisional biopsy of the affected lymph node.
