The acute disseminated form of Langerhans cell disease is called Letterer-Siwe disease, also known as multifocal Langerhans cell histiocytosis. This rare form mainly affects infants and young children, with symptoms including skin rash, liver and spleen enlargement, bone lesions, and respiratory distress. It can be life-threatening if left untreated. Eosinophilic granuloma and Hand-Schüller-Christian disease are other forms of Langerhans cell disease, but they are not the acute disseminated form. Reiter syndrome is a type of reactive arthritis and has no relation to Langerhans cell disease.
