- 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)
