Abstract
To report a case with a gouty tophus at the medial canthus. Observational case report. Review of the clinical, laboratory, photographic, and pathologic records of a patient with a gouty tophus at the medial canthus. A 27-year-old man had a 3-year history of gouty arthritis and poorly controlled hyperuricemia. A medial canthal mass without discomfort developed gradually over 3 months. An excisional biopsy was performed, and the tissue was fixed in formalin for pathology. Analysis of a routine hematoxylin-and-eosin-stained section disclosed a multilobulated pseudocyst filled with amorphous eosinophilic material. Further staining with nonaqueous alcoholic eosin and viewed under a polarizing microscope indicated the presence of birefringent urate crystals. Gouty tophus can develop progressively at the medial canthus, especially in people with uncontrolled hyperuricemia. A formalin-fixed specimen, stained with nonaqueous alcoholic eosin, demonstrates abundant birefringent urate crystals under a polarizing microscope.
