High procalcitonin and thrombocytopenic purpura in a case of Kikuchi-Fujimoto disease.

Kikuchi-Fujimoto disease is a mild and rare idiopathic disease, particularly in children. It is mostly characterized by painful cervical lymphadenopathy and/or prolonged fever and confirmed by histology. We report a case of Kikuchi-Fujimoto disease in a 14-year-old teenager with high procalcitonin concentration and thrombocytopenic purpura.
