A number of purported malignant giant cell tumors or examples of malignant PVNS have been documented in the English-language literature,[18-23] but many of these cases do not meet the criteria for diagnosis of malignant giant cell tumor of tendon sheath established by Enzinger and Weiss[25] or as modified by Bertoni et al.
Both our cases appear to qualify as examples of malignant giant cell tumor of tendon sheath (malignant PVNS) under the stringent criteria established by Enzinger and Weiss[25] and the subsequent modified criteria developed by Bertoni et al.
Thus, we believe this deposit represented a malignant giant cell tumor of tendon sheath based on both clinical behavior and morphologic findings.
They believe that cytogenetic aberrations in both the localized and diffuse forms of giant cell tumor of tendon sheath were similar, with at least 2 cytogenetic groups being distinguishable.
Abdul-Karim et al[30] analyzed the DNA content and proliferative indices of 14 cases of diffuse giant cell tumor of tendon sheath and 11 cases of localized giant cell tumor of tendon sheath.
