Parasites? No, peripheral nerve sheath tumors
On the same week, we received two suspected cases of bovine cysticercosis due to muscle lesions observed in two cattle from different geographical sources.
The first case was a 14-year-old cow that showed a single, nodular, whitish lesions on the masseter muscle.
The second was an 18-year-old, mixed breed, cow with lesions on the esophagus, the myocardium and the pectoral musculature. All of them were white, nodular and with a maximum diameter of 10 mm.
Interestingly, in both cases the parasitic etiology was not confirmed, it was in both cases a neoplasm originated in the cells that make up the peripheral nerve sheath. It is a relatively common neoplasm in cattle and can have a multifocal presentation.
