Abstract:
This article reviews the contribution of modern investigative techniques to the diagnosis of cutaneous lymphoproliferative diseases. Special attention is given to the significance of immunoglobulin and T-cell receptor rearrangements; as detected by Southern blotting and/or the polymerase chain reaction. Additional topics discussed include immunohistochemistry, cytogenetics, onco- and tumour suppressor genes and in-situ hybridization. It is recommended that the results of these techniques are interpreted in the form of a multifaceted diagnostic profile.
