title: Diabetic Charcot neuroarthropathy: The diagnosis must be considered in all diabetic neuropathic patients presenting with a hot, swollen foot.
abstract: The diagnosis of diabetic Charcot neuroarthropathy (CN) is challenging. This is especially true early in the disease process, when its classical presentation of an acutely inflamed foot may masquerade as other more common lower limb conditions. Prompt diagnosis and appropriate treatment reduces the risk of CN causing permanent incapacitating foot deformity or amputation. We report two cases in which the diagnosis was delayed, resulting in long-term sequelae. These cases highlight the importance of considering CN in patients with diabetic peripheral neuropathy, who present with a red, hot, and swollen foot.
