A capillary hemangioma in the gastrocnemius muscle of a Rhesus monkey is reported. It is believed to be the fourth vascular neoplasm described in Rhesus monkeys and the first to have developed in skeletal muscle. The tumor was a firm, hemorrhagic mass 5.0 × 6.5 cm. It was composed of a benign bed of proliferating capillaries. No distinct capsule separated the mass from the adjacent muscle, but collagenous trabeculae subdivided the tumor into packets of capillaries.
