Description

A 30-year-old male presented with swellings over left elbow, left ankle, base of the first meta-tarso-phalangeal joint of both feet (figures 13). He had ulcers over swelling of right meta-tarso-phalangeal joint and dorsum of same foot since 3 months. He also had polyuria and low-grade fever since 6 months. There was a chalky white discharge from the ulcers, which on examination under polarised microscope showed large number of needle shaped crystals with negative birefringence. Patient had normal I.Q level, there was no history suggestive of mutilating behaviour, morning stiffness, photosensitivity, genitourinary complaints, red eye, or Raynaud’s phenomenon. Patient’s elder brother had history of recurrent nephrolithiasis (He was not available for serum uric acid measurements). His maternal uncle died at young age due to renal failure. He never had any attack of typical gouty arthritis. Patient became afebrile with use of oral paracetamol. When patient reported for the first time his baseline creatinine was 0.9 mg/dl. He was started on tablet allopurinol 300 mg once daily and 2 weeks after initiation of treatment patient’s creatinine levels climbed to 1.3 mg/dl. Allopurinol was discontinued, and he was started on tablet febuxostat and is still continued on this treatment with a creatinine value of 1 mg/dl at present. His serum uric acid has come down from 10.5 to 7.5 mg/dl. The development of tophi in the absence of prior episodes of gouty arthritis is unusual. The first such patient was reported in 1965.1 Wernick et al presented six such cases and reviewed 26 previously published cases and found that these patients differed from those with typical gout in that they were older, more likely to be women, and usually had predominant or exclusive finger involvement.2 Most had renal insufficiency and many were receiving an anti-inflammatory or diuretic. Our patient was a young male and did not have exclusive finger involvement. He did have mild renal insufficiency for which he was put on febuxostat as its pharmacokinetics and pharmacodynamics are not significantly altered in patients with moderate renal insufficiency.3 This case has been primarily submitted for the striking image of the gouty tophi.
