Scrotal and penile edema in a patient with incomplete kawasaki disease: a case report and brief literature review

Abstract

Abstract Background Kawasaki disease (KD) is a medium artery vasculitis that predominantly affects children under age 5. Prompt diagnosis and treatment with IVIG and moderate dose aspirin is required to prevent the formation of coronary artery aneurysms. While scrotal edema and erythema have been seen in KD, here we present a distinctive case of incomplete Kawasaki with these features as well as penile edema. Case presentation A 2-year-old, unvaccinated, African American male presented with 4 days of fever, bilateral limbic sparing conjunctivitis, a papular rash, unilateral shotty cervical lymphadenopathy, mild right-hand edema, and scrotal and penile edema and erythema. His labs were significant for sterile pyuria, elevated ALT, anemia for age, and hypoalbuminemia. He was diagnosed with incomplete Kawasaki disease and was treated with IVIG and moderate dose aspirin. Echocardiogram was negative for coronary aneurysms. His symptoms resolved and he was discharged home with low dose aspirin. At his 2-week follow up, he remained well-appearing with no refractory Kawasaki symptoms. Conclusion This is a unique case of penile edema in KD which to our knowledge has not been previously reported in literature. An understanding of genitourinary symptoms in Kawasaki disease can help timely diagnosis and treatment of the disease.
