[en] It is acknowledged that tumour thickness, ulceration and lymph node invasion are the most important prognostic factors for cutaneous melanomas. Other histopathological features may also be informative. The aim of this study was to ascertain whether immunohistochemical methods can improve the detection of satellite micrometastases in primary melanoma patients. In addition, the predictive value of cutaneous satellite micrometastases for sentinel lymph node involvement was evaluated. A total of 265 primary cutaneous melanomas and 68 of the respective sentinel nodes were studied using a panel of seven antibodies directed against melanocyte-related antigens. In 12.4% of the 265 cases, small satellite micrometastases were detected by immunohistochemistry. Sentinel lymph node metastases were found in 14% of the 68 cases. Invasion of the sentinel lymph node correlated with the presence of cutaneous satellite micrometastases. It is concluded that the presence of cutaneous satellite micrometastases may be an indication for the performance of sentinel lymph node biopsy, and this finding calls for a closer follow-up of these patients.
