Patients with very severe gout accompanied by the formation of large, visible, palpable uric acid deposits known as tophi may require the drug pegloticase (Krystexxa[R]).
? Sometimes hard, white pimples, called tophi, form on the skin.
Patients with frequent episodes, gouty tophi, and radiological damage are treated with long-term urate-reducing agents.
(12) Similarly, physical examination may detect signs of arthritis, tophi, synovitis, or any comorbidity (such as kidney disease, metabolic syndrome, or obesity) that may affect AH diagnosis or management.
In this report, we described the rare presentations of symmetrical, bilateral, extensive, and neglected tophi on both elbows.
Tophi were gradually found in bilateral MTP, proximal interphalangeal joint, metacarpal phalangeal joints, intertarsal joints, and auricles, successively.
(6,8) Radiography is not useful in early gout because small erosions and tophi are difficult to detect, but such lesions are detectable in chronic gout.
Gouty tophi were not grossly observed in the fascia or muscle, but small tophi (-0.25-0.5 mm) were seen sporadically in the synovial sheaths of the flexor tendons, which can occur after many years in patients with poorly controlled gout [5].
Formation of large crystal deposits called "tophi", observed in chronic gout, can cause irreparable damage to the joints and lead to joint disability.
Of those with a tophus at baseline, 6 (16%) of 37 of the control/DE group and 4 (13%) of 31 of the DE/ DE group had complete resolution of all tophi between months 12 and 24.
