“…Inhibin-α is a specific marker for human and canine SCSTs. Ovarian epithelial tumors and germ cell tumors, however, are usually negative for inhibin-α (Akihara et al, 2007;Ichimura et al, 2010;Kudo et al, 2019;Namazi et al, 2015). In the present study, the tumor cells from 2 different components were strongly positive for inhibin-α together with vimentin, whereas those cells were negative for cytokeratin indicating that these tumor cells arose from sex-cord stromal origin.…”

“…Primary ovarian tumors are relatively uncommon tumors in dogs; however, they have been frequently reported in old, multiparous dogs or dogs with ovarian remnant tissues (Vissiennon et al, 2010). Overall, primary ovarian tumors account for 0.5%-1.2% of all canine tumors (Namazi et al, 2015). Generally, ovarian tumors are classified into 3 different types depending upon the origin of the cells.…”

“…Among these subtypes, the granulosa cell tumor is the most common. In dogs, SCSTs have been demonstrated in Cocker Spaniel, Rottweiler, Boxer, German Shepherds, Fox Terriers, Mongrels and Yorkshire Terriers (Deluchi et al, 2018;Diez-Bru et al, 1998;Namazi et al, 2015;Sung et al, 2007;Yamini et al, 1997).…”

A 12-year-old, spayed Yorkshire Terrier dog with a history of progressive abdominal distension was diagnosed with an ovarian sex-cord stromal tumor. Microscopically, the residual ovarian tissue sample was composed of 2 different tumor cell populations: a luteal-like cell and Sertoli cell components. These cells were notably immunopositive for vimentin, inhibin-α and neuron-specific enolase (NSE). On the basis of all findings, the tumor was diagnosed as luteoma and Sertoli cell tumor of the ovary developing from the ovarian remnant tissue.

“…Sex-cord stromal tumors include granulosa cell tumors, luteomas and thecomatas (Bertazzolo et al, 2004). Luteoma is a less common tumor type that has limited reports in mares, cats and monkeys (Namazi et al, 2015). There is not much information about breed predisposition in dogs however Bulldog and Boxer breeds display the highest risk (Sforna et al, 2003).…”

Ovarian tumors are rarely seen in bitches and they usually occur in older ages. The most common type of ovarian tumor is epithelial tumors. Hematological parameters are frequently affected by the presence of neoplasms. There are various types of anemia associated with neoplasms. In the present study; we investigated the relationship between complete blood count (CBC) and the presence of ovarian tumors in bitches. Seven bitches with ovarian tumors and 6 bitches with histologically healthy ovaries were selected for this study. Increased level of platelet (PLT) was determined in bitches with ovarian tumors and considered as a significant finding to estimate the cancer progression. Besides, red blood cells (RBC), hematocrit (HCT), and hemoglobin (HGB) levels were decreased in bitches with ovarian tumors, which might be associated with cancer related anemia. In conclusion, the evaluation of complete blood count in bitches with ovarian tumors can be important to estimate the hematological effect of tumor progression.

A 7-years-old female Golden Retriever dog was presented to the clinic with a multilobular mass protruding from the vulva. On clinical examination, the mass was observed on the circumference of the vaginal canal. The owner reported not noticing a pro-estrous bleeding for a year. On vaginal cytology, parabasal cells, intermediate cells, neutrophil infiltration and clumps of bacteria were determined. Mild anemia, severe leukocytosis and high MPV value were detected. As a treatment, vaginal mass was totally extirpated by partial vaginectomy and subsequently ovariohysterectomy were performed to avoid the re-occurrence of the vaginal tumor. Both vaginal mass and ovariohysterectomy materials were histopatologically examined. Benign tumors were diagnosed which were vaginal leiomyoma and bilateral ovarian luteoma. It was concluded that histopathological analysis of every surgically removed tissue should be performed in order not to miss a tumorous condition even if it does not show any symptoms.
