Pilarczyk A., 1973. The morphological and histological structure of tumours in the “cauliflower disease” (papilloma) of eels. Acta Ichthyol. Piscat. 3 (1): 91-106.
Tumours appearing on eels with the "cauliflower disease" are morphologically different from each other. The present paper was aimed at the investigation of a possible effect of these differences on a histological structure. The author′s attention was also paid to the initial stages in the papillae formation; the role of particular corium elements in this process was also taken into consideration.
