title: [Langerhans cell histiocytosis and breast].
abstract: Langerhans cell histiocytosis (LCH) is a rare systemic disorder, with a diversified presentation and natural history. It can compromise any organ. We report a case of a 32-year-old woman who came to our clinic with an asymptomatic palpable breast mass. She underwent excisional biopsy. Immunohistochemical and pathological evaluation revealed Langerhans cell histiocytosis. No multisystem involvement was found.
