摘要
Background: Perforating disorders are uncommon diseases characterized by transepidermal elimination histopathologically and include reactive perforating collagenosis, elastosis perforans serpiginosa, Kyrle’ s disease and perforating folliculitis. In addition, perforating disorders can develop in patients with diabetes mellitus, renal failure and even by accidental exposure of calcium salts. Methods: We report two cases of perforating disorder caused by chemical burn with commercially available salt- water.application for self- treatment of chronic dermatitis or pruritus. Results: The commercially used salt water for making bean curd was analyzed and it consisted of calcium and other salts without harmful heavy metals. We induced a similar phenomenon by experimental application of commercial salt water on guinea pigs. Conclusion: Bean curd is used as a food commonly in the Far- East, allowing a greater chance of exposure to salt water accidentally or occupationally. Bean curd is becoming more popular even in Western countries. To confirm causation, we induced a similar phenomenon in guinea pigs by experimental application of commercial salt water.
