The histopathological study showed, both in the spleen and in the peritoneal lesions, a neoplastic round cell proliferation surrounded by an abundant proliferation of connective tissue. Polymorphonuclear eosinophilic leukocytes could be observed infiltrating this tissue. Morphological diagnosis was compatible with a Mastocytoma<\/strong>.<\/p>\n

To confirm the diagnosis immunohistochemistry against C-kit receptor was done, with a positive outcome. Toluidin Blue stain revealed the presence of intracytoplasmic granules in the neoplastic mast cells.<\/p>\n

It is a rare neoplasm in pigs, we had previously described a case affecting the skin: Cutaneous Mastocytoma<\/a>.<\/p>\n

\"Marked<\/a>

Marked increase in size of the spleen, which presents a pale appearance.<\/p><\/div>\n

\"Detail<\/a>

Detail of the marble-like appearance of the splenic parenchyma.<\/p><\/div>\n

\"Miliary<\/a>

Miliary nodular lesions in the serous membranes of the abdominal cavity (intestines, stomach, etc.)<\/p><\/div>\n

\"Histopathological<\/a>

Histopathological study. A: <\/strong>H&E staining shows neoplastic mast cells surrounded by a fibrous matrix and presence of eosinophils infiltrating the mass (arrowhead).
