“…The occurrence of VT was usually reported in intact bitches (22). However, there are two reports on the occurrence of VT in a spayed bitch (23) and in a hysterectomized Poodle bitch (24). Similar to findings of Klein (22), all of the bitches with VT were intact in the present study.…”

The aim of the study is to evaluate the changes in clinical, hematological and histopathological parameters of the bitches with vaginal hyperplasia (VH), vaginal tumors (VT) and healthy reproductive tract (H), respectively. The study groups formed as; group VH (n=9), group VT (n=10) and group H (n=13). All bitches were examined clinically (vaginal cytology, vaginoscopy), hematologically and histopatologically. The bitches in group H were in anestrus and the bitches in group VH and group VT were in oestrus. Reduced levels of RBC, HGB, HCT and increase in WBC were detected in group VT. The averages of HGB level in group VH was tended to be lower than group H (P=0.05) while the averages of HCT level in group VH was significantly lower than to group H. The averages of RBC, HGB, HCT and WBC were not significantly associated with the degree of vaginal fold prolapse (VFP) (P>0.05) while the averages of PLT and PCT in bitches with type 2 VH were tended to be higher than type 3 VH (P=0.07). The histopathological examination of the vaginal masses in group VH revealed thickening of squamous epithelium and significantly loose and edematous connective tissue in the lamina propria. Histological diagnosis of the tumors in group VT were fibroma (n=4), leiomyoma (n=3), peripheral nerve sheath tumor (n=1), transmissible venereal tumor (TVT) (n=1) and leiomyosarcoma (n=1). In conclusion, hematological changes in bitches with vaginal mass were evaluated and mild anemia and leukocytosis were determined in bitches with VH and VT. To our knowledge, this is the first study that demonstrates the detection of mild anemia in bitches with VH and the differences in PLT and PCT related to the degree of VFP.

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.

“…Leiomyomas, fibroleiomyomas and fibromas are common, while leiomyosarcomas, lipomas, mastocytomas, adenocarcinomas and squamous cell carcinomas are rarely seen among tumors of mesenchymal origin [11]. In terms of the location of the tumors in the female reproductive system, it was determined 8 times more in the vagina and vulva compared to those in the uterus [12]. Vaginal lipomas have been found to occur sporadically with a low incidence in older bitches [3].…”

“…The most commonly reported vaginal tumors are leiomyomas which is reported to be located intraluminally. Surgical resection with blunt dissection was performed for lipomas disrupting physiological function of organs [2,10,12]. Furthermore, the mass excision with episiotomy or/and ovariohysterectomy is needed to be performed for leiomyomas commonly located as intraluminal [3,9].…”

Background: Lipomas are defined as a soft mass of well-differentiated adipose cells among mesenchymal tumors. Considering the localization of lipomas, these masses are commonly seen in subcutaneous tissue. The female reproductive tract is a rare site for development of lipomas and clinical findings appear depending on the size and localization. The connection of the mass with the vagina lumen causes different clinical findings. Intraluminal tumors protrude and arise from the vulva, while extraluminal tumors lead to perineal swelling. This case describes clinical, ultrasonographic, histological examination, and surgical management of extraluminal vaginal lipoma.Case: The present study reports a case of extraluminal vaginal lipoma in a 10-year-old Pitbull crossbred presented with anamnesis of a protruded tissue from the vulvar lips and dysuria following 6-month swelling in the perineum. Clinical examination revealed that the swelling was obvious and localized mostly on the lower left side of the perineum and the vaginal mucosa was protruded from the vulvar lips due to a mass. By vaginal palpation, the mass was not associated with the vaginal mucosa. The mass was located in the perivaginal region and transvaginal ultrasonography revealed a hypoechogenic mass. Based on clinical and ultrasonographic findings, surgery was recommended. The mass was adherent to the serosa of the vagina and it did not enclose the vaginal mucosa. Excision of mass was performed with careful blunt dissection avoiding any urethral disruption and periurethral tissues. After the mass was determined to be extraluminal, there was no need for excision of the vaginal tissue with the mass during operation. Using histopathological examination the mass was identified as a lipoma composed of adipocytes. In addition, ovariohysterectomy was not recommended following the diagnosis of vaginal lipoma.Discussion: Lipomas uncommonly can be localized in unpredicted rare areas such as vagina and vulva in older bitches. Although the majority of reported benign tumors in dogs recommend the surgery, medical treatment including the steroid injections is the other option to limit the lipomas. Considering the vaginal tumors, the surgical approach is also planned as laparotomy since leiomyomas are more common than lipomas. This approach partially results from the adherence of tumors to vaginal tissue. In addition, the location of the mass together without the adjacent tissue damage depending on whether it is intraluminal or extraluminal would make complete tissue removal. In previous reports, while symptoms such as perineal hernia of the lipoma were emphasized, the connection of the lipoma with the vaginal lumen was not evaluated as a significant factor determining the surgical approach. The mass was not connected to the vaginal mucosa and it was determined as extraluminal lipoma in the present study. Mass excision was performed by blunt dissection, avoiding urethral disruption and periurethral tissues. Unlike the most common approach in leiomyomas, this report did not require a total vaginectomy to remove the mass from the vagina. The ovariohysterectomy was not needed to be performed in the present study as in intraluminal vaginal tumors. It was believed that adhesions of lipoma with vaginal lumen is a determining factor in the combination of surgical techniques such as episiotomy and/or ovariohysterectomy. Lipomas should be considered among the tumors in the vaginal region of dogs brought with the complaint of swelling in perineum and protrusion of vaginal tissue.
