- Authors discuss the classification of primary cutaneous lymphomas created by the Cutaneous Lymphoma Study Group of the European Organization for Research and Treatment of Cancer (EORTC) in 1996, which is based on the clinical, histological, immunohistochemical and genetic features of cutaneous lymphomas. Unlike the previous histologic classifications it contains well-defined disease entities characterized by their clinical and histological picture, clinical outcome, behaviour and therapeutic response. This classification does not use the term of low grade or high grade lymphoma, but introduces the indolent, aggressive and provisional subgroups in the T-cell lymphomas, and indolent, intermediate and provisional subgroups in the B-cell group. Authors demonstrate the EORTC classification by their own cases calling the attention to the clinical and therapeutic difference between nodal and extranodal lymphomas, and discuss the up-to-date therapeutic possibilities.

- Cell adhesion molecules play a significant role in the cellular connection of normal cells. The cadherins are believed to act as tumour suppressors, and their altered expression and function have been associated with tumour development.The authors examined the expression of a Ca++ dependent intercellular adhesion molecule, P-cadherin using an immunohistochemical method in 69 surgically resected breast carcinomas.P-cadherin was detected in 30 cases (43.5%, cytoplasmic and/or membrane staining). The expression of P-cadherin was independent of tumour size and lymph node status, but correlated with a high tumour grade (grade III). In contrast, expression of E-cadherin correlated with lower tumour grade (grade I-II). P-cadherin expression was not detected in invasive lobular carcinomas.In general, P-cadherin was expressed at a lower frequency compared to E-cadherin, alpha-, and beta-catenin. These results suggest that an inverse relationship may exist between E- and P-cadherin in relation to grade, and that the expression of P-cadherin may be a marker of aggressiveness.
