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)

Has been found in cat, dog, cow, goat and horse
Arise from pericardial, pleural and peritoneal surfaces
May be related to inhalation of asbestos
Grossly:
- Multiple discrete nodules
Microscopically:
- Can appear as a carcinoma or fibrosarcoma depending on which tissue, covering or supporting, is predominant in the neoplasm
Rarely metastasise but are considered malignant
