Identification of undifferentiated tonsillar tumours, an immunological approach

ABSTRACT

Tonsillar squamous cell carcinoma of undifferentiated nature is difficult or sometimes impossible to distinguish from malignant lymphoma with the conventional methods. Twenty Six patients with undifferentiated tumours were chosen for this study. Using immunoperoxidase technique with anticytokeratin and T [200] [common leucocyte antigen] as antibodies, it was possible to reach the exact nature of these tumours. Our results gave 80% squamous cell carcinoma while the remaining 20% were proved to be malignant lymphoma. We believe this method is simple and accurate to identify these tumors
