Tóm tắt

ContentsThe present study describes the clinicopathological features of a mature cystic ovarian teratoma occurred in a 4 year old, cyclic, nulliparous Andalusian mare. The mass was discovered in the left ovary during a breeding soundness examination, and was hard in consistency and variously echogenic. Laparoscopy was performed to confirm the neoplastic change, followed by a unilateral laparotomic ovariectomy in the standing animal. On the cut surface the teratomatous ovary showed a large cyst filled with hair and sebaceous material and three small cysts containing mucous fluid, surrounded by solid areas where bone and cartilage could be recognized. Exceptionally, functional remnants of the ovary, including small follicles and a diestral corpus luteum were found near the tubal extremity. Histology revealed mature tissues foreign to the ovary including stratified squamous and respiratory epithelia, mucous, sebaceous and sweat glands, muscle fibres, fat and nervous tissue. The appearance of tracheal and lung architecture was occasionally observed.
