Four cases of undifferentiated tumors are described in which only a differential diagnosis could be obtained using light microscopy but a definite diagnosis was achieved when additional information was provided by immunohistochemistry. A scheme is presented for the use of immunohistochemistry to increase diagnostic precision in assessing tumours.
