Abstract
Tophaceous pseudogout is a rare variant of the calcium pyrophosphate dihydrate (CPPD) disorder, with predilection for the TMJ. It is characterized by calcific deposits composed of rhomboid- or rectangular-shaped crystals that exhibit birefringence when examined under polarized light. We hereby present a case of a 65-year-old man with left pre-auricular tenderness and malocclusion. CT imaging was notable for a left TMJ mineralized mass with erosion of the condylar head. Treatment involved excision of the mass with eminectomy, condylectomy, and a stock total TMJ reconstruction. In this report, important considerations for diagnosis, biopsy, and surgical treatment with emphasis on reconstruction for tophaceous pseudogout of the TMJ have been highlighted by the authors.
