[Kikuchi-Fujimoto disease in pediatric population: a case report and a review of literature].
A 10 year-old child, with a history of a right cervical mass, is admitted to the Costa Rican National Children's Hospital for workup. The mass appeared approximately 4 weeks before admission. Laboratory tests were performed and malignity, infection and immunologic causes were ruled out. A biopsy was performed revealing granulomas characterized by central necrosis with abundant karyorrhexis, surrounded by histiocytes, lymphocytes and giant multinucleated cells, without neutrophils. Special stains showed no microorganisms. Once infectious and immunologic causes were excluded, and based on the biopsy's result, treatment was ruled out. Twelve months later, the patient is still asymptomatic; therefore, the diagnosis of a Kikuchi-Fujimoto syndrome was proposed. This report constitutes the first pediatric case diagnosed in our country.
