Abstract
The histopathology of a disease is described which commonly affects young terrapins of the genera Clemmys, Pseudemys, and Graptemys kept in captivity. The first signs noticed are swelling of the eyelids and refusal to feed. Investigation of 32 terrapins revealed extensive epithelial metaplasia in the ophthalmic glands and in the excretory ducts of the liver, pancreas, and kidneys. The localization and the type of metaplasia seen are similar to those which occur in man, cattle, horses, sheep, and fowl suffering from avitaminosis A. Occasional successes of treatment with vitamin A support the assumption that the mortality is mainly due to avitaminosis A and should be treated or prevented accordingly.
