[Classification of lymphogranulomatosis].

Histological and cytological studies of preparations of peripheral lymphatic nodes in 1081 patients before treatment were carried out. In 76 patients there were also investigated morphological changes in the spleen, mesenteric lymphatic nodes and parts of the liver obtained in laparotomy. Basing on the analysis of the literature and their own findings, the authors think it reasonable to single out the following 8 histological variants of untreated lymphogranulomatosis: focal lesion; a group of variants with nodular sclerosis, with various cellular composition--lymphocytic predominance, mixed cellularity, predominance of lacunar cells; a group of variants without sclerosis consisting of lymphoid predominance and mixed cellular variant; a group of lymphatic depletion combining the reticular variant and diffuse fibrosis. The variants indicated above may be both independent and transitional stages.
