Older gerbils often develop spontaneous neoplasms. These most commonly affect the skin, adrenal glands, kidneys, spleen, intestine and the female reproductive tract. The most commonly encounteredt type of neoplasms include leiomyomas, subcutaneous fibrosarcomas, sebaceous gland adenomas, adenocarcinomas, duodenal adenocarcinomas, adrenal adenomas and malignant melanomas.

Geriatric problems in gerbils commonly include cystic ovaries and chronic interstitial glomerulonephritis. Cystic ovaries occur in 50% of geriatric females and can result in decreased fertility. Macroscopic pathologic findings will include moderate to large cysts on the surface of the ovaries. Glomerulonephritis develops with concurrent polyuria and polydipsia together with progressive weight loss. Macroscopic pathology will show neoplastic lesions within the kidneys.

Macroscopic pathologic findings will include moderate to large cysts on the surface of the ovaries together with metritis, endometrial hyperplasia and myometrial mineralisation.  

Glomerulonephritis develops with concurrent polyuria and polydipsia together with progressive weight loss. Macroscopic pathology will show neoplastic lesions within the kidneys which will be shrunken, fibrotic and pitted. COncurrent neoplasia is common.
