Three cases of spontaneous tumors (one benign and two malignant) are reported in nude rats bred at the All-Union Cancer Research Center, Academy of Medical Sciences of the USSR. An eight-month-old rat developed a sebaceous adenoma in the region of the abdomen. The other one-year old rat developed hemoblastosis with infiltrations in the lung, liver, kidneys, spleen, and lymph nodes. A 4-month-old rat developed colloidal (follicular) thyroid cancer.
