Oral and craniofacial manifestations in a Hunter syndrome patient with hematopoietic stem cell transplantation: A case report

We described herein the oral and craniofacial features of a 7-year-old boy, diagnosed in utero with mucopolysaccharidosis II (MPS II), who was treated with hematopoietic stem cell transplantation (HSCT) at 70 days of age. The main oral clinical findings were the following: macroglossia, posterior cross-bite, crowding, pointed cuspid teeth, delayed tooth eruption, retained primary teeth, and enamel hypoplasia. The image examination showed: retention eruption, posterior primary teeth with short roots, absence of some permanent teeth, and stretching of the stylohyoid processes bilaterally. This patient showed the importance of early diagnosis and HSCT therapy in attenuating the clinical and radiographic oral and craniofacial manifestations of the MPS II patient.
