According to prior reports, similar to mammals, fish are frequently affected by neoplastic proliferations. These neoplasms are classified according to the mammalian tumor classification System (Rahmati-Holasoo et al., 2010). Squamous cell carcinoma (SCC) is one of the most common forms of skin neoplasm in which cells in the epithelial layer of the skin develop into a malignant tumor. SCC has been reported in both fresh and marine water fish (Mawdesley-Thomas and Bucke, 1967). Squamous cell carcinoma has been reported in a number of species, for example, Atlantic salmon, Salmo salar L. (Roberts, 1972); oscar, Astronotus ocellatus (Rahmati-Holasoo et al., 2010); rudd, Scardinius erythrophthalmus (Hanjavanit and Mulcahy, 2004); gudgeon, Gobio gobio (Mawdesley-Thomas and Bucke, 1967); gulf menhaden, Brevoortia patronus Goode (Fournie et al., 1987); and the hybrid sunfish (Fitzgerald et al., 1991). In spite of the fact that reports have been previously published on SCC in various species of fish, to the best of the author’s knowledge, this is the first report on SCC in platy fish (Xiphophorus maculatus) in the world.
