Peritoneal mesothelioma (Image sourced from BioMed Image Archive with permission)

Peritoneal

  • Mesotheliomas
    • Malignant - implantation rather than metastasis
    • Mainly cattle and dogs, occasionally in other species
    • Can be congenital in calves
    • Arise from serosa of pericardial, pleural and peritoneal cavities
    • Multiple small nodules, may be pedunculated, few milimeters to few centemeters, may present as villous projections
    • May be associated with milky or bloody effusions
    • Histologically usually appear similar to adenocarcinoma (papillary) or fibrosarcoma (spindle cells)
