Apocrine adenocarcinoma in the ear pinna of a 2 month old cat

Apocrine adenocarcinoma (AAC) is a rare malignant neoplasm of the sweat glands that affects adult/senior cats and dogs. AAC is characterized by a highly aggressive local behaviour, with possible involvement of regional lymph nodes, but low systemic metastatic rate at distant sites. The prognosis is directly related to the degree of histologic differentiation. The case described involves a 2 month old kitten presenting a neoformation localized on the concave surface of the ear pinna, subsequently identified histopathologically as AAC. To the authors’ knowledge, this is the first documented case of AAC in a cat under one year of age.
