classification and diagnosis of cutaneous lymphoma

Whilst the Haematoxylin and Eosin (H&E) stain continues to be the universally accepted routine stain of choice,
over the past couple of decades there have been significant advances in immunohistochemistry (IHC) which have
revolutionised our diagnostic approach to tumour and to a less extent non tumour histopathology specimens. The
immunohistochemistry field is rapidly changing with improving technology and an increasing array of commercially
available antibodies are now available. Prior to the immunohistochemistry age, pathologists only had a limited
number of histochemical stains (for instance mucin and silver stains) together with electron microscopy to assist in
classification of tumours
