*'''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 Cavity & Membranes Hyperplastic and Neoplastic - Pathology|pleural]] and [[Peritoneal cavity - Anatomy & Physiology|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)
