[Radiologic-pathologic correlations in tumors and tumor-like lesions of the hand (author's transl)].

Since 1972, 267 tumors or tumor-like lesions of the hand in 257 patients were examined at the bone tumor registry by the Swiss Society of Pathology in Basel, Switzerland. This is 9% of a total of 2,800 bone tumors submitted. An analysis revealed 254 benign tumors or tumor-like lesions and 13 malignant tumors, among them 2 metastases of tumors of unknown origin. As expected, enchondromas (n=81) and pigmented villo-nodular synovitis of the tendon sheath (n=104) were the most frequent tumors. All other tumors or tumor-like lesions appeared only as solitary cases or in small numbers. The radiologic characteristics of some of the lesions are reviewed and their histology is presented. Furthermore, some important points of differential diagnosis are discussed.
