title: Liposarcoma or invasive lipomatosis in flower horn fish, hybrid cichlid: clinical, radiological, ultrasonographical and histopathological study.
abstract: Liposarcoma or invasive lipomatosis affecting three indoor aquarium fish (flower horn fish, hybrid cichlid) is characterized, by the presence of mature adipocytes of variable sizes and by an invasive behaviour, which affected internal organs and eyes of all cases. Detailed macroscopic, radiological, ultrasonographical and histopathological features are presented. All fish had bilateral exophthalmia with some masses around the eyes. Ultrasonography confirmed the presence of hyperechoic masses in the eyes. Histopathology of all cases described the presence of variable-sized adipose cells in the eyes. The suggested diagnosis is well-differentiated liposarcoma or invasive lipomatosis. This is the first report of liposarcoma or invasive lipomatosis in flower horn fish, hybrid cichlid.
