Thirty‐six cases of cutaneous malignant melanoma with histologically involved lymph nodes were studied during a 2–10 year study period, and the characteristics of the metastasized nodes and the associated prognosis were compared. The results were as follows: 1) the survival rate in cases with 3 or fewer (n=16) metastasized nodes was significantly higher than in cases with 4 or more positive nodes (n=20); 2) the survival rate in cases in which metastasized nodes were limited to one regional lymph node section (n=12) was significantly higher than in cases where metastasis extended to two or more intra‐regional sections of nodes (n=24); 3) cases which had nodes measuring 3.00 cm or less (n=25) had significantly higher survival rates than those with nodes of 3.01 cm or more (n=11). Therefore, the results indicate that the number of metastasized lymph nodes, the extension into regional lymph node sections, and the size of the metastasized lymph node(s) can be considered as important prognostic factors for melanoma patients.
