Abstract
Subcutaneous nodules, removed from the shoulder of 1 and the stifle of another mature stallion, were identified histologically as localized nodular tenosynovitis. Neither horse exhibited any evidence of pain or impaired movement. One lesion had been present for 2 months, the other for 1 year. These nodules resulted from a proliferation of small round to fusiform cells with differentiation to fibroblasts or active phagocytes, including multinucleated giant cells. The older lesion had undergone considerable collagenization.
