In a review of neoplasm registry records at Kansas State University (1961 through 1971), 162 sebaceous gland adenomas were reported in 31 breeds of dogs, representing 5.0% of 3,240 neoplasms recorded. Mean age of the affected dogs was 9.5 years. Females accounted for 56.1% of the recorded sebaceous gland adenomas. The tumors were removed surgically for biopsy in all dogs; 24 dogs had multiple concurrent skin neoplasms of a different cell type, and 7 dogs had recurrence of sebaceous gland adenomas, without metastases, and required further surgery. The skin of the hindquarters, abdomen, and thorax was a principal site (54%) of the sebaceous gland adenomas.
