Clinical and histopathological investigation of symmetrical alopecia with associated chronic pruritus in tufted capuchin monkeys (Sapajus apella apella).

Methods: A pruritic and alopecic disease was investigated in a group of tufted capuchin monkeys (N = 12), but due to ethical reasons, four random animals were further investigated by numerous diagnostic methods.

Isotretinoin Treatment for Autosomal Recessive Congenital Ichthyosis in a Golden Retriever.

Ichthyoses are hereditary cornification disorders that manifest with abnormal differentiation and desquamation of keratinocytes in a form of generalized dry and scaly skin. In golden retriever dogs, autosomal recessive congenital ichthyosis (ARCI) has been associated with mutations in the gene. In human medicine, isotretinoin is frequently used to treat ARCIs.
