Cancer in Wild River Otters

Primary pleural squamous cell carcinoma in a free-ranging River otter (Lontra canadensis)
  • Cancer

Abstract

An adult female North American river otter (Lontra canadensis) presented with multiple intrathoracic masses identified histologically as squamous cell carcinoma. Immunohistochemical staining patterns for high- molecular-weight keratin, p40, p63, calretinin, and TTF-1, along with the gross and histologic findings, indicated a primary pleural squamous cell carcinoma as the most likely diagnosis.
