Abstract
An adult koi carp presented with a pedunculated tumour on the dorsal head was surgically treated under clove oil sedation. The mass was ligated and excised while the fish remained submerged. Post excision arterial bleeding was controlled by compression and surgical skin glue. The carp recovered quickly, resumed feeding the next day and showed normal behaviour; wound healing progressed with granulation and epithelial growth. Histology identified the lesion as a papilloma. This case demonstrates the feasibility of individualized surgical intervention in ornamental fish.
Keywords:Cyprinus rubrofuscus var. Koi; Papilloma; Benign epithelial tumour; Surgical excision; Fish pathology
