Abstract:
Sickle cell disease (SCD) and sickle cell trait (SCT) can be associated with sudden unexpected death in the pediatric population, usually due to pulmonary complications occurring within the acute chest syndrome (ACS). Musculoskeletal complications can occur and are classically limited to bone infarcts. The occurrence of bone pathology centered upon the epiphyseal growth plate in SCD/SCT is extremely rare, and multiple such injuries in a single patient have not been previously reported. Herein, we describe a case of sudden unexpected death in a 5-year-old child with undiagnosed SCT due to the ACS, with widespread epiphyseal and periosteal bone lesions mimicking multiple inflicted injuries at autopsy. This case highlights the importance of clinicopathological correlation and is the first to describe SCT pathology as a mimic of nonaccidental injury.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
