The authors describe the case of a two-year-old boy who presented vesico-papular lesions all over the trunk which became crusted, in addition to tumorations with necrosis in the cervical region. In the course of his hospitalization, he had sudden onset of convergent strabismus on the right side. Histopathological and immunohistochemical examination of cutaneous lesions revealed typical aspects of Langerhans' cell histiocytosis, thus confirming diagnosis. The patient underwent chemotherapy, with a significant improvement in his clinical picture.
