Introduction: Osteopetrosis is a rare hereditary bone dysplasia characterized by insufficient osteoclast activity that results in increased bone mineral density. Hematopoietic stem cell transplantation (HSCT) can reverse skeletal abnormalities and restore hematopoiesis.
Clinical Case: We present the case of a 3-year and 2-month-old male patient with the diagnosis of osteopetrosis.
