Acorn-related acquired pseudomelanosis in Calabrian black pigs.

ABSTRACT:

Background

Melanosis of lymph nodes in black pigs has generally been related to regression of congenital melanoma and, occasionally, to ingestion of acorns. The aim of this manuscript is to confirm the hypothesis of a possible acquired acorn-related pseudomelanosis in the Nero Calabrese pig, a swine breed belonging to the group of Italian native breeds and whose coverage area corresponds to the region of Calabria, southern Italy.
