We describe a case of focal argyrosis of the conjunctiva clinically simulating a melanoma. An 82-year-old woman was referred for an asymptomatic pigmented conjunctival lesion. Her only significant past ocular history was strabismus surgery 76 years earlier. Biopsy of the conjunctiva and lateral rectus muscle revealed the discoloration was pigment granules. Energy-dispersive x-ray microanalysis revealed the pigmentation to be silver deposits. The patient had strabismus surgery probably using a silver clip. Argyrosis should be considered in the differential diagnosis of focal pigmented conjunctival lesions.
我们描述了一例临床上疑似黑色素瘤的结膜局灶性银质沉着症病例。一名82岁女性因无症状的结膜色素沉着病变前来就诊。她唯一重要的眼部既往史是76年前的斜视手术。结膜及外直肌活检显示变色处为色素颗粒。能量色散X射线微分析显示色素沉着为银沉积。该患者可能在斜视手术中使用了银夹。在结膜局灶性色素沉着病变的鉴别诊断中应考虑银质沉着症。
