In a study of the toxic effects of mercury on kidneys of various vertebrate species including man, Edwards found that anatomic alterations were virtually limited to the proximal convoluted tubules.1The following cases are presented as examples of the nephrotic syndrome due to membranous glomerulonephritis secondary to contact with compounds containing mercury.
