Abstract

There are many difficulties in the use of the Ridley & Jopling classification in daily practice. The author identified the morphologic parameters whose variations permit to distinguish the polar types and borderline groups according to Ridley. If we avoid the inconstant hi s tologic al terat ions we bel ieve that thi s di s t inc t ion depends bas i cal ly on the fol lowing parameters: epithelioid cell, granuloma of epithelioid cells, number of lymphocytes and number of bacilli. A critical analysis is performed of each of these parameters and the author concludes that they are scarce, ande that there are great difficulties for the identification and interpretation of their variations for classification purposes. These difficulties are even more important during the reactional episodes.
