X-Cell Pseudotumors in a Hardhead Catfish 'Arius felis' (Ariidae) from LakePontchartrain, Louisiana, USA

摘要

An X-cell epidermal lesion is described for the first time from the hardheadcatfish Arius felis (Ariidae). The lesion exhibited an unusual growth pattern but did not involve any visceral organs. Histologically, the lesions resembled those previously described for coldwater fishes. This is the first report on X-cell lesions from Lake Pontchartrain, Louisiana, and hardhead catfish represents the first warmwater species affected with the disease.
