| Patients with long-standing gout may have tophi over the olecranon prominence, first metatarsal joints, or pinnae. |
|
| Joint damage in hyperuricemia causes classical attacks of gout but tophi may also develop in cartilage, tendons and other tissues. |
|
| Only a minority of patients with hyperuricemia develops tophi and gouty arthritis. |
|
| Chalky deposits called tophi may appear under the skin around joints and in the cartilage of the ears. |
|
| Uric acid may also collect under the skin, which is known as tophi, or in the urinary tract as kidney stones. |
|
| Though they are good for reducing the risk of gout and tophi, they actually increase the risk of kidney stones. |
|
| These deposits are called tophi and can cause significant joint damage over the years. |
|
| Crystal deposits may also build up under the skin around the joints and behind the ears, causing small lumps known as tophi and, in a few cases, in the kidneys. |
|
| While usually not painful, tophi can become swollen and tender during flare-ups of gout. |
|
| Sometimes the crystals form chalky splinters, or tophi, which may break through the skin. |
|
| Uric acid can form clumps called tophi, often in the tips of the ears, knuckles or within tendons and joints. |
|
| If gout is untreated and the disease becomes advanced, deposits of urate crystals may form into nodules called tophi beneath the skin. |
|
| When one includes podagra and the presence of tophi, the specificity increases. |
|
| A general screening examination did not show evidence of any subcutaneous gouty tophi about the upper and lower extremities. |
|
| About half of cases involve the big toe, but it can present as gouty tophi, kidney stones, or urate nephropathy. |
|
| With long-term lowering of uric acid the tophi may decrease in size and the volume and kidney function may improve. |
|
| Due to vascularization of the granulation tissue around the tophi, one might even see variable enhancement within the same tophus. |
|
| Gouty tophi involving the external ear may occur in the helix and antihelix, presenting as firm nodules that may ulcerate. |
|
| Gout presents as arthropathy, tenosynovitis, bursitis, and cellulitis of noninfectious origin, urinary tract calculi, and very commonly as soft-tissue deposits known as tophi. |
|
| The sub-articular lucencies most probably represent intra-osseous tophi. |
|
|
|
| In long-standing gout, deposits of uric acid crystals may collect in the earlobes and the soft tissues of the hands, forming small, creamy lumps called tophi. |
|
| Tophi cause erosions of joints, but also deposit in the skin and soft tissue, including the bursae, tendons and articular cartilage. |
