American writers have described these peculiar tumors under the name synovial lesions of the skin. Hyde1 was apparently the first to direct attention to them. Later Lingenfelter,2 Ormsby3 and Sutton,4 reported cases, and recently MacKee and Andrews5 and Montgomery and Culver6 have recorded cases and discussed their pathology. The situation of the fibromas, their gelatinous contents and the apparent extension of their capsule to the articulation, suggested that they were intimately related to the synovial membrane of the interphalangeal articulations. Hence, on clinical grounds they were considered to be of synovial origin. MacKee and Andrews confirm this finding by roentgenographic and histologic examinations. Montgomery and Culver, on the other hand, apparently on clinical inspection alone, emphatically deny their synovial connection, and state that they are merely cystic warts.
Shortly after MacKee and Andrews' last paper, three cases came under my observation and so provided
