SOUZA, Tatiana Mello de; FIGHERA, Rafael Almeida; SCHMIDT, Claudete  and  BARROS, Claudio Severo Lombardo de. Lichenoid keratosis in a dog. Cienc. Rural [online]. 2009, vol.39, n.3, pp.937-940.  Epub Jan 23, 2009. ISSN 1678-4596.

Lichenoid keratosis is a rare proliferative dermatopathy reported in human beings and dogs. In dogs the disease is characterized by well circumscribed hyperkeratotic plaques distributed in the skin of pinnae and, less frequently, in the inguinal region. This report describes a case of lichenoid keratosis in a six-year-old male Dobermann dog which had multifocal verrucous lesions in the internal aspect of the pinnae and slightly scaly, overpigmented alopecic lesions in the axillae and inguinal region; both lesions had a clinical course of approximately three months. The diagnosis was based on the association of the clinical and histopathological findings.

Keywords : diseases of dogs; lichenoid keratosis; hyperplasic diseases of the epidermis; lichenoid diseases of the dermis; dermatology; dermatopathology.
