Abstract
In human and veterinary medicine, mixed Müllerian tumors (MMTs) are rarely diagnosed neoplasms of the tubular female genital tract. Although there are case reports of malignant MMTs in various species, benign MMTs have only been described once in a macaque. Here we present a case of benign MMT in a 12-y-old goat, and review the literature on uterine, cervical, and vaginal neoplasia in goats. The doe was presented with vaginal discharge and was euthanized because of the high suspicion of intraabdominal neoplasia. On gross examination, an ulcerated vaginal mass was identified. Histologically, 2 distinct cell populations were present: smooth muscle cells that were well differentiated and positive for alpha–smooth muscle actin, and ciliated columnar epithelial cells that lined ductal structures and had no signs of malignancy. These findings led to the diagnosis of neoplasia of Müllerian origin. Benign MMT should be considered as a differential diagnosis for uterine and vaginal neoplasms in goats.

Abstract
Spindle cell epitheliomas of the vagina are rare benign tumors of uncertain histogenesis. It has been hypothesized that they originate from a pluripotent cell population. Here, we report 2 cases of spindle cell epitheliomas of the vagina. Both patients presented with a painless vaginal nodule. The resected lesions were solid, well circumscribed, and composed of a proliferation of epithelioid or epithelial cells admixed with spindle cells without atypia. The 2 cellular populations expressed epithelial and mesenchymal markers. Based on these morphologic and immunohistochemical findings, a diagnosis of spindle cell epithelioma was rendered in both cases. Furthermore, we describe for the first time the expression of WT-1 (Wilms’ tumor protein 1) and calretinin in addition to the previously defined immunohistochemical profile.

Abstract
Spindle cell epithelioma is a very rare benign tumour of the vagina, which contains epithelial and mesenchymal components and co-expresses the markers for both. It has its origin in the epithelial cells of the remnants of the vestibular gland. The presence of glandular structures and the pattern of immunostaining, help in the differentiation of these tumours from the other common vaginal tumours.

Abstract
The so-called mixed tumors occur in a variety of sites throughout the body. While most cases are encountered in the salivary glands, several cases have been described in the female genital tract. A variety of monikers have been applied to this lesion including "spindle cell epithelioma." As in other locations, the vaginal spindle cell epithelioma (VSE) consists of a proliferation of both epithelial and mesenchymal components. Based on our extensive review of the literature, we present the 53rd reported case of VSE. More significantly, we present the most up-to-date review of this lesion, including its immunohistochemical and electron microscopic features. We also review the theories pertaining to its histogenesis incorporating current embryologic data, which together suggest a Müllerian derivation.

Abstract
Mixed tumor of the vagina is a rare benign neoplasm that is composed of epithelial and mesenchymal cells. The majority of tumors are asymptomatic and simple tumor excision is curative. We report a case with pathological confirmation that was seen in a 42-year-old woman. On ultrasound examination the lesion appeared as an ovoid hypoechoic mass, 2.0 x 2.7 cm in size, arising from the lower third of the vagina. The lesion was well defined, solid and showed diffuse hypervascularity on color flow images. Magnetic resonance imaging of the pelvis showed a well-circumscribed ovoid mass (2.0 x 2.5 cm) on the left lateral vaginal wall. On T2-weighted images the mass appeared as a homogeneous hyperintense lesion, while on T1-weighted images it was difficult to discern the mass from the vaginal wall. After intravenous administration of gadolinium the mass showed progressively increasing homogeneous enhancement. The lesion was excised without complication and there was no evidence of recurrence at the 10-month follow-up.

Abstract
Mixed tumors of the vagina (MTsV) are rare benign neoplasms characterized by an admixture of well-differentiated epithelial cells and stromal-type cells in various proportions. In contrast to mixed tumors in other anatomic sites, the histogenesis of the vaginal tumors is unclear. We studied the immunohistochemical profile of 13 examples to explore their histogenesis and determine whether their immunohistochemical profile might be useful in the differential diagnosis. The panel of antibodies used and the number of cases studied were: AE1/3 (12), cytokeratin 7 (CK7) (13), cytokeratin 20 (CK20) (13), epithelial membrane antigen (EMA) (13), muscle actin (MA) (12), desmin (11), h-Caldesmon (13), CD10 (13), CD34 (11), CD99 (8), and S-100 (7). Eight out of 12 tumors were positive for AE1/3, 7/13 for CK7, 2/13 for CK20, and 6/13 for EMA. MA was positive in 11/12 mixed tumors, desmin in 10/11 tumors and h-Caldesmon in 5/13. All tumors were extensively positive for CD10; CD34 was positive in 7/11; and none out of eight tumors showed membranous CD99 staining. Focal S-100 immunoreactivity was seen in 1/7 tumors. These results show that MTsV coexpress epithelial and mesenchymal markers. The expression of muscle actin (usually extensive), and focal desmin and h-Caldesmon positivity suggests the presence of a smooth muscle or myoepithelial component; however, the S-100 negativity and diffuse CD10 expression argue against it. Positivity for muscle markers does not help distinguish MTsV from smooth muscle or skeletal muscle tumors. The frequent expression of CD10 negates its use in the differential diagnosis with endometrial stromal tumors, and the CD10 and CD34 expression suggests that mixed tumors may arise from a primitive pluripotential cell. MTsV are positive for h-Caldesmon and CD10, two markers that have been used in gynecologic pathology primarily to aid in establishing the smooth muscle or endometrial stromal phenotype of a neoplasm.

Abstract
We present a case of benign mixed tumor of the vagina with its typical clinicopathologic and expanded immunohistochemical features. The strong coexpression of the mesenchymal spindle cell component with epithelial markers such as CK7, together with strong CD10, Bcl2, and estrogen and progesterone receptors favors a mullerian derived tumor. The tumor is best labeled as benign mixed mullerian tumor as originally designated.
