Abstract

An undifferentiated ethmoid carcinoma with uncommon initial stage invasion into the brain parenchyma in an indigenous pig is reported. A nodular, fleshy tumor mass, located in the posterior part of the nasal sinus adjacent to the cribriform plate and pressing on the brain, was noticed on post mortem. Rarifaction of the cribriform plate was evident. The histological picture showed sheets of cells with nuclear atypia, anaplasia and hyperchromatic nuclei infiltrating into the brain parenchyma. Upon detailed examination, the neoplasm revealed a mixture of spindle, squamous and round tumor cells. The case was diagnosed as ethmoid carcinoma of undifferentiated type, as the epithelial origin of the neoplasm was proved by immunohistochemical positivity against an anti-pancytokeratin antibody.
