Zoophilia is a type of paraphilia whereby the person gets sexual pleasure in sexual intercourse with animals. There is a paucity in the medical literature on zoophilia. We present a rare case of zoophilia occured in manic episodes. A 68-year-old man who had both zoophilia and irritability, ouditory halucinations, grandiose and mystic delusions was assessed by our clinic. After antimanic treatment abnormal sexual behavior disapperad. Patient had similar paraphiliac symptomes during his previous five manic episodes. Hypersexuality is a common symptom of mania but paraphilia is rarely reported. We recommend that due to the prevalence of this condition, questions exploring the topic should be asked in psychiatric interview. [Anadolu Psikiyatri Derg 2015; 16(2.000): 146-149]
