Abstract
The present communication reports a spontaneous case of non-viral, metastatic infundibular adenocarcinoma in a 74 week old commercial layer chicken. On necropsy examination, mesentery, serosal surface of intestine and pancreas were studded with 5 mm grayish white nodules. Fimbrial region of oviduct contained varying sizes of multiple single to lobulated grayish white nodules. Serosal surface of tubular neck region showed tiny pearl-like nodules and the mucosal surface was diffusely thickened. Microscopically, cuboidal neoplastic cells were arranged in acinar and tubular pattern in the serosal layer of infundibulum. The cells appeared as variable sized cuboidal cells with indistinct cell borders, eosinophilic granular cytoplasm, round nuclei, indistinct nucleoli and fine chromatin granules. Transcoelomic nodules showed neoplastic cells and structures similar to those of the oviductaltumor.
