The histological and histochemical features of 74 tumors arising from the mucosa of the ethmoid in bovines were studied in detail. The tumors encountered were all carcinomas of varying degrees of malignancy. They were classified as adenocarcinoma (30), squamous cell carcinoma (35) and undifferentiated carcinoma (9). In some of the adenocarcinomas, a transition of columnar cells to squamous cell type was evident. By histological and histochemical studies it was convincingly established that this tumor is a primary growth arising specifically from the olfactory mucosa of the ethmoid region.
