NHP – RHESUS
7y 5m year old male rhesus macaque (Macaca mulatta).
This monkey received 6.5 Gray total body irradiation four and a half years prior to necropsy as part of a study examining the acute and chronic effects of irradiation.

Kidney: Glomus tumor
Glomus tumors are rare, typically benign tumors arising from periendothelial modified smooth muscle cells which form the Sucquet-Hoyer canal, a structure that regulates temperature and blood flow in the subcutis, and are most commonly described in the fingers of women.
Glornus tumors are rarely reported in domestic species. One publication from 1984 described four glomus tumors in adult rhesus monkeys, which had received total body irradiation, however the radiation dose was not specified. 4 While the most common anatomic location in humans are the finger tips, malignant glomus tumors with metastases have been reported, including several humans who had either primary or metastatic renal lesions.
