What does tophus mean?
A tophus refers to a hard, painless deposit of monosodium urate crystals that forms under the skin or in joints and tissues of individuals with gout. These deposits are a hallmark of chronic gout and can appear as lumps or nodules, typically on the fingers, toes, or ears. Tophi are usually painless but can cause discomfort and limited mobility if they grow large enough. The presence of tophi indicates advanced gout, and their formation is often associated with long-standing, poorly managed gout. Tophi can be a significant concern for patients as they can lead to further joint damage and increased risk of gout attacks. Effective management of gout involves addressing the underlying causes of tophi formation, such as high uric acid levels, and may involve medication and lifestyle changes.
