Gerbils (Meriones unguiculatus), given N-methyl-N-nitrosourea iv once weekly for 15 weeks at doses related to the mean lethal dose, developed tumors of the species-specific midventral sebaceous gland. These neoplasms were more frequent in males than females and were histologically classified as sebaceous adenomas or carcinomas of varying differentiation.
