Abstract
We report four cases of adult-onset Langerhans cell histiocytosis (LCH) with central nervous system (CNS) lesions in the hypothalamic-pituitary region. The first clinical symptoms were diabetes insipidus (two patients), hypothyroidism (one patient), and decreased libido/erectile dysfunction (one patient). Diagnosis was delayed as the CNS lesion was not initially suspected to be secondary to LCH, with a median time from symptom onset to treatment of 3.0 (range <1–5.3) years. In three patients, the tumor mass was effectively reduced by chemotherapy; however, all patients continue to exhibit hypopituitarism. Early diagnosis and initiation of treatment are required to improve the outcome of CNS-LCH in adult patients.
