Nineteen wild ringed seals (Phoca hispida) were killed in winter 1999 to assess the health status of seals harvested in eastern Hudson Bay (Quebec, Canada). One of these seals, an 11-yr-old male, had a poorly differentiated adenocarcinoma that severely constricted the lumen of the distal small intestine. The tumor was characterized by proliferation of polygonal epithelial cells that formed closely packed acini and cords. This appears to be the first reported case of adenocarcinoma of the small intestine in Pinnipedia.
1999年冬季，19只野生环斑海豹（Phoca hispida）被猎杀，以评估在加拿大魁北克省哈德逊湾东部捕获的海豹的健康状况。其中一只海豹是一只11岁的雄性，患有低分化腺癌，严重狭窄了远端小肠的管腔。肿瘤的特征是多边形上皮细胞增殖，形成紧密排列的腺泡和索条。这似乎是首次报道的鳍足类动物小肠腺癌病例。
