Final answer:
Kawasaki disease is the diagnosis suggested by the symptoms of fever, rash, oral lesions, peeling hands and feet, and lymphadenopathy listed in the question. It is differentiated from other conditions by the characteristic combination and presentation of these symptoms. Correct diagnosis is essential for appropriate treatment and management.
Step-by-step explanation:
The systemic vasculitis condition with the symptoms of fever, rash, oral lesions, peeling hands and feet, and lymphadenopathy described is characteristic of Kawasaki disease.
Kawasaki disease is the correct diagnosis for systemic vasculitis with fever, rash, oral lesions, peeling hands and feet, lymphadenopathy.
Kawasaki disease is an acute, self-limited vasculitis that most commonly affects children under 5 years of age. The classic diagnosis is made by the presence of fever lasting at least five days (which is often higher than 39°C) together with at least four of the following: rash, swelling of hands or feet, red eyes, enlarged lymph nodes in the neck, and inflammation of the mouth, lips, and throat.
Staphylococcal scalded skin syndrome (SSSS), Rocky Mountain spotted fever (RMSF), and serum sickness are other conditions that have some overlapping symptoms, but they present differently and do not include the full constellation of symptoms seen in Kawasaki disease. SSSS, for instance, is characterized by redness and peeling of the skin but does not typically involve fever and lymphadenopathy. RMSF can involve a petechial rash that begins on the hands and wrists but it differs with the presence of high fever and severe illness potentially leading to fatality.
