This paper reports a case of unilateral extracorporeal ectopic testes in a captive coati (Nasua nasua) in the State Park of Dois Irmãos Zoo, Recife/PE, Brazil. The testicle was located in the subcutaneous tissue of the inguinal region not adhered to the surrounding tissues. After bilateral orchiectomy, both testes were measured, fixed with 10% formalin buffered and embedded in paraffin for histopathological evaluation. The left testis measured 1.2 cm width by 1.7cm length, and the right one measured 1.5 cm width by 2.0 cm length. The ectopic testes had seminiferous epithelium without post-meiotic germ cell lines. The non-ectopic testis had several changes in the seminiferous epithelium that indicated degeneration. In both epididymis, the lumen did not contain sperm and the major epithelial structural alterations were more distinct in the epididymis associated to the ectopic testicle. In conclusion, the ectopic testis and epididymis had lesions compatible with testicular exposition to body temperature. Non-ectopic epididymis and testis had minor lesions but could be related to the infertility of the coati. |
