Tophi are the visible dermatological signs of gout. A case of tophaceous gout in a middle-aged man with no other metabolic derangement is being presented with multiple tophi on the hands and feet overlying joints as well as on the fingers and toes. We thought it to be of educational value to demonstrate needle-like crystals of urate by polarizing microscopy. X-rays of hands and feet showed dramatic destructive changes. The patient presented with mottled hypopigmentation on anterior and posterior knees and dorsa of hands and feet where he applied hot "aankda" leaves and covered them with bandage resulting in irritant dermatitis with postinflammatory hypopigmentation. This proved to be a red herring in this case.
痛风石是痛风可见的皮肤表现。本文报告一例中年男性痛风石性痛风病例,该患者无其他代谢紊乱,其手足关节上方、手指和脚趾出现多个痛风石。我们认为通过偏振显微镜展示尿酸盐针状结晶具有教育意义。手足X线显示出显著的破坏性改变。患者双手、双足背部及双膝前后出现斑驳状色素减退,这些部位他曾用热的“aankda”树叶敷贴并用绷带包扎,导致刺激性皮炎伴炎症后色素减退。在该病例中,这被证明是一个干扰因素。
