Argyria is a rare cutaneous manifestation of silver deposits in the skin, characterized by a grayish blue discoloration, particularly in sun-exposed areas. We report the case of a patient with a history of schizoaffective disorder and type 2 diabetes mellitus who presented with argyria of the face and neck. The patient had a history of ingesting colloidal silver proteins (CSPs) for approximately 10 years as a self-prescribed remedy for his medical conditions. Colloidal silver protein has gained popularity among patients who seek alternative medical therapies. Argyria is the most predominant manifestation of silver toxicity. It is unclear if our patient began taking CSP because of his schizoaffective disorder or if silver toxicity may have induced somatic delusions; however, it is important for physicians to have a thorough understanding of alternative therapies on the market. We present a detailed background on silver ingestion and its systemic effects.
银质沉着症是皮肤中银沉积的一种罕见皮肤表现，其特征为皮肤呈蓝灰色变色，尤其是在暴露于阳光下的部位。我们报告了一例患有精神分裂症和2型糖尿病的患者，该患者出现了面部和颈部的银质沉着症。该患者有大约10年摄入胶体银蛋白（CSPs）的病史，他将其作为自我开的治疗自身疾病的药物。胶体银蛋白在寻求替代医学疗法的患者中越来越受欢迎。银质沉着症是银中毒最主要的表现。目前尚不清楚我们的患者是因为患有精神分裂症而开始服用CSPs，还是银中毒可能诱发了躯体妄想；然而，医生全面了解市面上的替代疗法非常重要。我们提供了关于摄入银及其全身影响的详细背景信息。
