“…Clinical manifestations associated with this side effect include uterine diseases, persistent oestrus, follicular cysts and ovarian neoplasia, which are mainly reported in older female dogs (Arlt et al., 2011; Palm & Reichler, 2012) but can occur in younger female dogs as well (Brändli et al., 2021). The high concentrations of LH and FSH that are released during the flare up reaction may precipitate subclinical ovarian or uterine conditions, which are common in intact older female dogs (Arlt & Haimerl, 2016) and unusual in younger female dogs (Sforna et al., 2003; Troisi et al., 2023). For this reason, the off‐label use of deslorelin for oestrus suppression in older female dogs is not recommended due to the high frequency of underlying uterine or ovarian diseases in these patients.…”

“…2020b; Nielsen et al., 1976). The main predisposing factor is age as most tumours are diagnosed in bitches older than 10 years (Hayes & Young, 1978; Nielsen et al., 1976; Norris et al., 1970); although occasionally granulosa cell tumours (Coggeshall et al., 2012; Norris et al., 1970; Troisi et al., 2023), adenocarcinoma (Troisi et al., 2023) and teratoma (Coggeshall et al., 2012; Patnaik & Greenlee, 1987; Troisi et al., 2023) may be diagnosed in young to adult (1.5 to 6, years of age) female dogs. Other predisposing factors like breed are not confirmed and require further investigation.…”

Reports on neoplasms in bears are scarce, especially concerning ovarian tumors. A large primary ovarian neoplasm with multiple metastasis was found during the necropsy of a 14-year-old free-ranging Eurasian brown bear (Ursus arctos) from Northwestern Spain. Histopathology and immunohistochemistry allowed for the diagnosis of a sex cord stromal tumor. This is a complex group of neoplasms which differ in the predominant cell morphology and immunohistochemical features. The microscopic examination revealed two types of cells, one with eosinophilic cytoplasm, intermingled with larger vacuolated cells rich in lipids. The evaluation of the immunoreactivity to different markers, frequently used in the characterization of gonadal tumors (INHA, inhibin-alpha; PLAP, placental alkaline phosphatase; Ki-67; α-SMA, actin alpha-smooth muscle) and inflammation patterns (IBA1, ionized calcium-binding adapter molecule for macrophages; CD3 for T lymphocytes; CD20 for B lymphocytes), displayed significant INHA positive immunostaining of neoplastic cells, as well as inflammatory cell infiltration, mainly composed of macrophages and B lymphocytes. These findings were consistent with a malignant ovarian steroid cell tumor, not otherwise specified. The present study characterizes an unusual type of neoplasm, and also represents the first report of an ovarian sex cord stromal tumor in Ursidae.
