The diagnosis of malignant melanoma must be followed by treatment shown to be effective. Therefore a correct diagnosis, including staging, that will permit a meaningful prognosis and treatment, is essential. The usefulness and great specificity of immunological methods is based on the detection of antigens characteristic of neoplastic and reactive cells. In cases of malignant melanoma, immunohistochemistry has limited practical value in the routine diagnosis of melanocytic lesions. The method may be important, however, in the differential diagnosis of, for example, malignant melanoma vs. non-melanocytic anaplastic neoplasia, malignant vs. benign melanocytic lesions, etc. Recent advances in relating the immunostaining of antigens to the development of tumor cells, such as proliferation and apoptosis, metastatic potential, etc. have given considerable importance to the immunomorphological evaluation of malignant melanomas. Likewise, immunotherapy requires the immunophenotyping of the reactive cells of the immune system.
