Mucocutaneous Lymph Node Syndrome (C0026691)

Definition (MEDLINEPLUS)

Kawasaki disease is a rare childhood disease. It makes the walls of the blood vessels in the body become inflamed. It can affect any type of blood vessel, including the arteries, veins, and capillaries.

No one knows what causes Kawasaki disease. Symptoms include

  • High fever that lasts longer than 5 days
  • Swollen lymph nodes in the neck
  • A rash on the mid-section and genital area
  • Red, dry, cracked lips and a red, swollen tongue
  • Red, swollen palms of the hands and soles of the feet
  • Redness of the eyes

Kawasaki disease can't be passed from one child to another. There is no single test. To diagnose it, doctors look at the signs and symptoms. They may also use an echocardiogram or other tests. It is mainly treated with medicines. Rarely, medical procedures and surgery also may be used for children whose coronary arteries are affected.

Kawasaki disease can't be prevented. However, most children who develop the disease fully recover - usually within weeks of getting signs and symptoms. Further problems are rare.

Definition (MSHCZE) Multisystémové onemocnění (vaskulitida) připomínající polyarteriitis nodosa postihující obv. děti nebo mladistvé. Zahrnuje vysokou horečku, zduření mízních uzlin, kožní a slizniční změny (palmoplantární erytém, exantém, olupování kůže na distální části prstů, enantém, malinový jazyk), postižení srdce (myokarditida, postižení koronárních tepen, arytmie), hematologické změny (leukocytóza, trombocytóza) Léčí se podáváním gamaglobulinů, salicylátů. Prognóza je obv. dobrá, ale některé případy s těžšími kardiálními komplikacemi mohou probíhat nepříznivě. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) A vasculitis characterized by inflammation of the arteries, particularly the coronary arteries. The vasculitis may lead to aneurysm formation and possibly, heart attacks. It affects young children who usually present with persistent high fever, redness of the mucous membranes of the mouth, redness of the palms and soles, skin rashes, lymphadenitis, and joint pain and swelling.
Definition (MSH) An acute, febrile, mucocutaneous condition accompanied by swelling of cervical lymph nodes in infants and young children. The principal symptoms are fever, congestion of the ocular conjunctivae, reddening of the lips and oral cavity, protuberance of tongue papillae, and edema or erythema of the extremities.
Definition (CSP) systemic disease primarily of infants and young children, characterized by skin rash, swelling of hands and feet, enlarged cervical lymph nodes, "strawberry tongue", dry and cracked lips, high fevers, and coronary artery disease.
