Abstract
In this case report, we describe a novel occurrence of tumoral calcium pyrophosphate dihydrate crystal deposition disease (TCPPDCD) in a 76-year-old man that presented as an unusual, intraosseous, metadiaphyseal lesion of a long bone causing a pathologic fracture. A routine intralesional biopsy was performed, demonstrating granular deposits composed of polarizing, overlapping rhomboid crystals consistent with TCPPDCD. With limited numbers of reported cases of TCPPDCD, and the atypical intraosseous origin seen in this case, it is paramount to thoroughly evaluate all cases of TCPPDCD to clearly differentiate key findings that are essential in diagnosing and managing TCPPDCD.
