title: Isolated histiocytosis X of the hypothalamus. Case report.
abstract: Failure to consider histiocytosis X in the differential diagnosis of hypothalamic masses may lead to inappropriate empirical radiotherapy. This report concerns a case of histiocytosis X of the hypothalamus, unassociated with systemic histiocytic lesions, in which early biopsy allowed specific therapy with subsequent total regression of the lesion.
