Fibromas were observed on the lips of adult female and juvenile angel fish (Pterophyllum scalare) from 3 Florida farm populations. Tumor prevalence in each population was < 1%. Affected fish were clinically normal except for those with large tumors, which had weight loss caused by physical obstruction of food intake. Fibromas originated as elevated masses from the mucocutaneous junction near the midline of the upper and/or lower lips. Characteristic features included dense fibrous stroma covered by thickened, stratified squamous epithelium, numerous intraneoplastic teeth, and scattered foci of stromal inflammation. Electron microscopy revealed intracytoplasmic type-A retrovirus-like particles in stromal cells from all tumors. Attempts to transmit fibromas, using a cell-free tumor ultrafiltrate, were unsuccessful. The relationship of the intraneoplastic viral particles to the development of lip fibromas in angel fish is uncertain.
