L’approccio al bambino con poliuria-polidipsia

The paper describes the case of a 4-year-old boy who suddenly developed intense thirst and excessive urination. After ruling out diabetes mellitus, subsequent tests led to a diagnosis of central diabetes insipidus. Further investigations to identify the underlying cause revealed cystic lung lesions indicative of Langerhans cell histiocytosis, for which the child was referred to paediatric haematology-oncology to begin chemotherapy.
