title: Use of immunocytochemistry in the diagnosis of metastatic carcinoma.
abstract: Metastasis of unknown primary site is a common clinical problem. Immunohistochemistry has been shown to be a useful tool in the identification of the primary site. The availability of new antibodies specific for a wide range of antigens and working on routinely fixed, paraffin-imbedded material will ensure that this technique will continue to offer useful information in the search for an elusive primary tumour.
