A case report of diffuse pigmented villonodular tenosynovitis involving the entire ulnar bursa and a review of the literature are presented. There have been few reports of the diffuse form of pigmented villonodular tenosynovitis involving the hand as compared to the localized nodular form, which is a common tumor of the hand. Complete tenosynovectomy of the involved areas is recommended.
