Rapid development of gouty tophi after diuretic therapy.

Increasing attention has been drawn to the role played by diuretics in the pathogenesis of gout, particularly in the elderly.

Her presentation with acutely inflamed tophi without any history of joint involvement, only 3 months after starting treatment, was highly unusual.
