A Case of a Missing Proximal Humerus.

Case Presentation: In this case, we demonstrate how a small radiolucency in the proximal humerus can progress to an even larger problem within a few months in a patient without follow-up. Our patient's ultimate diagnosis was renal cell carcinoma with metastasis to the right proximal humerus, completely obliterating the affected bone.

Discussion: In many underserved communities, patients have limited access to medical care, particularly specialty care.
