Abstract

The aim of the present study was to determine the morphologic and histopathologic characteristics of tumors observed in samples from moribund Capoeta capoeta. For this purpose, ten fish, captured from the Firat River located in southeastern Anatolia of Turkey, were examined for gross malformations and histopathological morphology. Externally, two different morphological types of tumours were detected in the anus region and on the ventral part of the operculum of one of the examined fish. In this study, tumours in a moribund fish were identified as benign because they were well differentiated, non-infiltrative and non-metastatic. In the histological examination, the external growth located in the ventral region of the operculum was characteristic of a papilloma showing exophytic inverted development. This is our first report on both melanomacrophage and green fibrils in the papilloma. The other observed pathological growth, covered with hemorrhagic skin and located near the anus, was characteristic of a benign tumour (subcutaneous lipoma) which constituted typical adipocytes. Thus, our study detected two different types of benign tumours in Capoeta capoeta, and it is the first time being reported in a cyprinid species
