Adult-onset Periodic Fever, Aphthous Stomatitis, Pharyngitis and Cervical Adenitis Syndrome Responsive to Colchicine.

We herein report a rare case of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome that occurred in an 18-year-old man. He visited our hospital with recurrent episodes of a fever, pharyngitis and adenitis without suggestive findings of infection. These episodes resolved within 5 days and recurred quite regularly, with an interval of about 30 days. As the febrile episodes significantly impaired his quality of life, he was treated with colchicine (0.5 mg) as prophylaxis. This completely prevented the episodes during six months of follow-up. Colchicine may therefore be effective in cases of adult-onset PFAPA syndrome.
