The immunohistochemical approach to tumor typing has dramatically improved our possibilities in the objective diagnosis of neoplasms. Use of optimal material and careful techniques will help to maintain good sensitivity, specificity, and reproducibility of immunohistochemistry. However, the complexity of antigen patterns in tumors, and lack of comprehensive knowledge about them requires caution in the interpretation of results, and may prohibit the simple use of diagnostic algorithms. Especially it is not certain whether the results obtained from typical representatives of various tumor entities will pertain to borderline cases and to undifferentiated variants of the same entities. Use of panels of antibodies rather than the use of single “diagnostic” tests will help to avoid these diagnostic pitfalls. However, all tumor types do not have immunohistochemically distinctive features. This emphasizes the need to use other techniques in such cases, and also suggests that some entities, such as malignant fibrous histiocytoma, are from the point of view of immunohistochemistry diagnoses only made by exclusion rather than being specifically diagnosable entities. All diagnostic immunohistochemistry has to be interpreted in the context of standard histological examination.
