Intraosseous Gouty Osteolytic Lesion in Calcaneus.

Tophaceous gout often occurs in soft tissues, and gouty invasion to the bone is rare. To date, only one case of isolated intraosseous gouty invasion to the calcaneus has been reported. We report here a rare case of an intraosseous calcaneal gouty cystic lesion treated with curettage and allogenous and autogenous bone graft. Satisfactory function and pain relief were obtained at 12-month follow-up, without any evidence of recurrent disease.
