Langerhans cell hyperplasia is a group of diseases characterized by the proliferation or dissemination of the Langerhans cell, which can come in the form of localized benign lesions, or extensive disseminated invasive neoplastic lesions. These lesions mainly invade the patient's bone. In this paper, we describe the case of a 3-year-old boy who was admitted to the pediatric department with sternum pain. Following a focused sternum ultrasound, a diagnosis was made of Langerhans cell histiocytosis.
