“…The case presented here together with the previous reports (Sontas et al. 2010a,b), demonstrate that neoplastic and non‐neoplastic conditions may develop in the ovaries, uterus and vagina if the ovaries are preserved or unintentionally left in the abdominal cavity during an elective surgery.…”

A 11-year-old, spayed, female mixed breed-dog was presented with an abdominal mass that was detected 1 month ago. Upon abdominal palpation a large, firm, oval shaped, movable mass was found in the mid-abdominal region. Survey radiograph of the abdomen demonstrated an oval soft tissue dense mass located on the right side of the abdominal cavity. A large, heteregenous and cystic mass with solid components occupying the majority of the abdomen and a small, cystic mass with solid components caudal to the left kidney were identified by transabdominal ultrasonography. Computed tomography scans revealed bilateral ovarian masses, and a small volume of retroperitoneal fluid on the right side. A cystic, but otherwise solid mass located in the right ovary and small retained left ovary encapsulated in the ovarian bursa were excised surgically by midline laparotomy. Histopathological examination of the excised mass from the right side revealed a large cystic structure consistent with an ovarian cyst and multiple corpora lutea and follicles at different maturational stages were detected in the left ovary. The precise origin of the ovarian cyst could not be determined by morphological appearance. Immunohistochemical staining suggested a cyst of surface epithelial origin. At re-examination 6 months after the surgery, the bitch appeared healthy and the clinical findings were all normal. To our knowledge, the cyst described here is the largest reported in an incompletely ovariohysterectomized bitch.

“…In reviews on dogs with vaginal/vulvar tumours, 65–97.5% of the dogs were determined to be sexually intact (Thacher and Bradley 1983; Kydd and Burnie 1986; Manothaiudom and Johnston 1991). We previously reported a clinical case of a uterine leiomyoma after an incomplete ovariohysterectomy in a 16‐year‐old poodle bitch which was presented for evaluation of tenesmus, with the ability to attract male dogs and a willingness to mate (Sontas et al. 2008).…”

A 15-year-old, spayed, female poodle dog was presented for evaluation of a mass of tissue prolapsed from the vulva. The dog had been hysterectomized when it was 5 years old. A vaginal mass had been removed approximately 10 months before presentation. Haematological and serum biochemistry analyses demonstrated mild leucocytosis and glycaemia. A vaginal smear was predominantly made up of parabasal cells and intermediate cells with no neoplastic cells. Thoracal and abdominal radiographic findings were unremarkable. The ovaries could not be identified using abdominal ultrasonography. A midline exploratory laparotomy identified both ovaries that were surgically excised. The vaginal mass was also removed following an episiotomy procedure. Histopathological examination of the mass demonstrated that it was a neurofibroma. Both ovaries had cystic changes. Four months after the surgery, the owner reported that the dog was clinically normal. To the authors’ knowledge, this is the first reported case of a vaginal neurofibroma after an incomplete ovariohysterectomy in the dog.

“…Esses neoplasmas são hormônio-dependentes e, como observado no presente trabalho, ocorrem em fêmeas não-castradas. Há apenas um relato de leiomioma uterino em uma cadela de 16 anos, parcialmente castrada, a qual apresentava resquício de ovário e útero (Sontas et al 2008).…”

Os arquivos de biópsia do período de 2000 a 2010 do SPV-UFRGS foram revisados e levantados os casos de neoplasias mesenquimais de genitália (útero, cérvix, vagina e vulva) de cadelas. Realizou-se estudo retrospectivo de 43 casos, incluindo caracterização histológica, coloração tricrômico de Masson (TM) e imuno-histoquímica (IHQ). As principais raças acometidas foram Cocker, Poodle e Pastor Alemão, porém o maior número de casos foi observado em cães sem raça definida (SRD). A idade média dessas cadelas foi de 10,6 anos (variação de 3 a 10 anos). Quanto à localização dos tumores, 44,2% estavam na vagina, 27,9% no útero, 23,3% na vulva e 4,6% na cérvix. Histologicamente, 46,5% eram leiomioma, 41,9% fibroleiomioma, 7,0% fibroma e 4,6% leiomiossarcoma. Na coloração de TM, os fibromas apresentaram todas as células neoplásicas coradas em azul (colágeno), os leiomiomas e os leiomiossarcomas apresentaram menos de 50% de colágeno em meio às células neoplásicas musculares e os fibroleiomiomas mais de 50%. Na IHQ, os fibromas apresentaram marcação positiva para vimentina e negativa para desmina. Todos os leiomiomas eram positivos para vimentina (em mais de 50% células) e para desmina (75% dos casos em mais de 50% das células e 25% em menos de 50%). Em um dos casos de leiomiossarcoma houve imunomarcação para vimentina e ausente para desmina e, no outro, ocorreu o oposto. Os fibroleiomiomas apresentaram marcação para vimentina em 94,4% (em mais de 50% células) e para desmina em 77,8% (64,3% em menos de 50% das células e 35,7% em mais de 50%).
