چکیده
INTRODUCTION Canine ovarian tumours are divided into 3 groups depending on their origin; germ cell tumours, sex-cord stromal tumours and epithelial cell tumours. Germ cell tumours include dysgerminomas, teratomas and embryonal carcinomas. Stromal tumours include granulosa-theca cell tumours, thecomas and luteomas. Epithelial neoplasms make up about 40–50 % of all ovarian growths and originate from structures under the ovarian epithelial surface. This is characteristic only in the bitch. Their growth is most commonly papillary (adenoma or adenocarcinoma) or cystic (adenoma or adenocarcinoma). Papillary adenocarcinomas could affect one or both ovaries. They are characterised by a large size and there is involvement of the ovarian stroma, bursa and in most cases, the peritoneum. When metastases are present, they appear in the kidneys, mesenteric lymph nodes and in the lungs. Clinically excretory, alimentary and respiratory disorders may be present. Cystadenomas originate from the rete ovarii, generally affecting one or, very rarely, both ovaries. They are composed of multiple thinwalled cysts filled a with transparent fluid. Ovarian tumours cause various disorders in the sexual cycle such as anoestrus, nymphomania, masculinisation, hyperadrenocorticism and alopecia, or they could be asymptomatic. The present report records the clinical signs, ultrasonogaraphic, radiographic, surgical, pathoanatomical findings and the therapy of a bilateral ovarian cystadenocarcinoma in an 11-year-old bitch.

Ovarian cystadenocarcinoma is characterized by marked heterogeneity and may be composed of an admixture of histologic growth patterns, including acinar, papillary and solid. In the present study, a case of isolated small intestine metastasis of ovarian papillary cystadenocarcinoma was reported.

Synchronously occurring primary gynecological malignancies are rare, and most commonly reported synchronous female genital malignancies are ovarian and endometrial. It is postulated that the extended Mullerian system, comprising the ovarian epithelium, fallopian tube, uterine corpus and cervix, may respond as a single morphological unit to a carcinogenic process, thus producing primary tumours ...
متن کاملTesticular papillary serous cystadenocarcinoma: a rare case report and review of the literature
Papillary serous cystadenocarcinoma of the ovary is a common tumor but occurrence of ovarian type papillary serous cystadenocarcinoma in the testis is very rare. Herein we report such a case in a 49-year-old man presenting with testicular swelling. In this tumor, mesothelioma of tunica vaginalis should be excluded by immunohistochemistry. The best treatment is radial orchiectomy and it is very ...
