Twenty years of porcine neoplasms

SESC collaborating pathologists have compiled all the neoplasms diagnosed in Catalan pig slaughterhouse during the last 20 years. This work, published in the journal Porcine health management, also includes a systematic review of the literature on all neoplasms diagnosed in this species as well as a classification of lymphoid neoplasms based on the WHO criteria adapted for animals.

During 20 years (1998-2018) a total of 56 neoplasms have been diagnosed in pig carcasses in slaughterhouses in Catalonia. The most reported neoplasm during this period was lymphoma (28). Within lymphomas, the B-cell type was the most common, being the diffuse large B-cell lymphoma (15/28) the most represented subtype. Other submitted non-lymphoid neoplasms included melanoma (7), nephroblastoma (3), mast cell tumor (2), liposarcoma (2), osteochondromatosis (2), papillary cystadenocarcinoma (1), peripheral nerve sheath tumor (1), lymphoid leukemia (1), fibropapilloma (1), hemangiosarcoma (1), hepatoma (1), histiocytic sarcoma (1), pheochromocytoma (1) and osteosarcoma (1).

With more than 20 million pigs that pass through slaughterhouses in Catalonia each year, the existence of a well-established Slaughterhouse Support Network allowed the compilation of comprehensive data for further epidemiological and pathological studies, particularly about less commonly reported lesions in livestock such as neoplasms in pigs.  (EV)
