title: [Scabies vs. histiocytosis X: a possible diagnostic error].
abstract: Scabies is a relatively common disease among Spanish children. The classic papulovesicular type is not usually a diagnostic problem. Therefore, the nodular type, much less frequent, is unknown for a lot of specialists (except dermatologist), and even it is mistaken for Histiocytosis or Lymphoma. Authors present a female infant, 6 months old, with nodular skin lesions whose first diagnosis was X-Histiocytosis. Regarding the big difference between the two processes (in respect of prognosis and treatment), this chance should be excluded, among others, when X-Histiocytosis is suspected in a child with sole skin affectation.
