Treatment of a facial myxoma in a goldfish (carassius auratus) with intralesional bleomycin chemotherapy and radiation therapy

A 4.5-year-old Ranchu goldfish (Carassius auratus) was presented for evaluation of a slowly growing facial mass of six months ′ duration. The mass, identified histologically as a myxoma, was noted to be protruding into the oral cavity and causing exophthalmia of the left eye. Two intralesional chemotherapeutic treatments of 2.5 U/kg bleomycin were performed 14 weeks apart. Reported side effects consisted of mild lethargy noted for two days following the second administration. Four weeks following the initial bleomycin administration, the owner appreciated a reduction in tumor size of 60%, however tumor expansion was occurring 11 weeks following administration.
