Abstract
Brenner tumor is a rare neoplasm of the vagina. This tumor is diagnosed according to the criteria of ovarian tumors. We report here a 64-year-old postmenopausal woman with a 2.0-cm sessile vaginal polyp for 9 years. Microscopic examination showed unusual features of no gland appearing in the tumor, but the other two characteristic components of transitional islands and dense fibrous stroma were observed. The tumor was diagnosed as a vaginal Brenner tumor on the basis of the definition proposed by the World Health Organization classification of female reproductive organ tumors. In our case, part of the epithelial nests of the Brenner tumor showed basaloid cell differentiation with peripheral palisading, and irregular papillary hyperplasia was observed around the epithelial nests similar to a borderline tumor. However, no mitotic activity or nuclear atypia was present in either the epithelial or stromal components. The presence of epithelial nests requires attention in the medical history of the patient. Our patient did not have a history of primary urothelial carcinoma. Our patient’s benign vaginal Brenner tumor with different morphological characteristics supports the current notion that Walthard nests might act as possible precursor lesions.

Diagn Pathol 2020; 15:22.

Abstract
BACKGROUND Extraovarian Brenner tumors (EOBTs) are extremely rare and can be observed incidentally in both female and male patients, raising concerns regarding the origin of Brenner tumors. CASE PRESENTATION A 53-year-old postmenopausal woman presented with a nodular lesion in the left side of the corpus uteri, which was found at a routine health check. Macroscopically, the lesion appeared as a solid nodule with a yellowish-gray cut surface, approximately 6 cm in greatest diameter. Microscopically, the lesion consisted of well-defined epithelial nests and spindled stromal cells. Parenchymal cells expressed CK7, GATA3, CK5/6, 34βE12, and p63. A single layer of cavity-lined cells with umbrella-like shape showed apical Uroplakin III positivity. Stromal cells were positive for SMA, ER, and PR. The final diagnosis was EOBT and the patient was followed for 2 months with no recurrence. CONCLUSIONS We report here the third case of EOBTs in the uterus. The combination of morphologic and immunohistochemical results supported the involvement of urothelial metaplasia in the development of EOBTs. The similarities between EOBTs and Walthard nests made Müllerian epithelium an attractive candidate as the cellular origin. Changes of tissue structure or sex hormones imbalance may lead to the translocation of Müllerian remnants to distant organs, explaining the pathogenesis of EOBTs.

Abstract
Background Brenner tumors almost always develop in the ovary. Exceptionally, extraovarian Brenner tumors have been reported in the lower abdomen or pelvic organs. Here, we introduce a peculiar case of an extraovarian Brenner tumor arising in the omentum. Case presentation A 43-year-old woman presented with a palpable abdominal mass. Computed tomography (CT) scan revealed a 9.0-cm solid mass in the omentum. The tumor was not associated with pelvic structures, including the ovaries. It was excised under the clinical impression of an extragastrointestinal stromal tumor or neurogenic tumor. Grossly, the mass was a well-circumscribed solid tumor, with yellow-tan cut surface and minute cystic spaces. Microscopically, the tumor showed well-defined epithelial nests with variable cystic changes embedded in an abundant fibrous stroma. The cells within the nests were reminiscent of benign urothelial cells in that they had oval, frequently grooved nuclei. The epithelial cells focally showed a gradual transition into the surrounding stromal cells with short spindled features. The urothelium-like cells were positive for pancytokeratin, WT-1, p63, CK7, uroplakin-III, and GATA-3 but were negative for CD34, CD10, CK20, c-KIT, DOG-1, PAX-8, and calretinin. Morphological and immunohistochemical features of the tumor were the same as an ovarian Brenner tumor, and so it was diagnosed as an extraovarian Brenner tumor. Conclusions Although the location of the tumor was very unusual, we could diagnose the tumor as an extraovarian Brenner tumor on the basis of the histologic and immunohistochemical findings. This is the first case of extraovarian Brenner tumor arising in the omentum near the stomach ever reported in the English literature.

Abstract
Extraovarian Brenner tumors are extremely rare. We report a case of vaginal Brenner tumor occurring in an 84-year-old woman. The tumor presented with vulvar irritation and soreness and consisted of a 1.8-cm polypoid mass arising from the lower third of the vagina. Microscopically, it had all the 3 components--urothelial islands, glands, and fibrous stroma--characteristic of a Brenner tumor. We suggest that vaginal Brenner tumors arise from a metaplastic process within the mullerian epithelium.

Abstract
This case report describes a tubulosquamous polyp resembling a penis in the uterine cervix. A 34-yr-old, gravida 0, para 0, woman showed an 18 × 8 × 5 mm polypoid lesion in the uterine ectocervix. The polyp had a penis-like appearance; the tip looked like glans penis and the middle portion resembled the shaft of the penis. Its surface was covered by squamous epithelium, and tissues resembling those of a urethra, corpus spongiosum penis, and external orifice urethra were observed. Foreskin-like tissues were also observed, although a corpus cavernosum penis was not seen. Skene glands and Cowper glands were also observed. Immunohistochemically, Skene glands and the urethra-like epithelium were focally positive for prostate-specific antigen and/or prostatic acid proteins. Histologically and immunohistochemically, the polypoid lesion overlapped with a tubulosquamous polyp of the vagina and ectopic prostatic tissue of the uterine cervix and encompassed these lesions in the lower female genital tract. The most likely theory of histogenesis is a developmental anomaly and misplacement of Skene glands.

Abstract
Tubulosquamous vaginal polyp is a rare form of lesion. It is thought to derive from displaced paraurethral Skene's gland which is the female equivalent of the prostate gland in men. We report on a case of tubulosquamous vaginal polyp in a 77-year-old female patient. Histological examination showed prominent epithelial nests in a spindle cell-rich stroma. The nests were predominantly squamous in type with small tubules at the periphery of the island. Using immunohistochemistry the tubules were found to be positive for CK7, prostate-specific acidic phosphatase (PAP) and androgen receptor (AR) but negative for CK 5/6 and prostate-specific antigen (PSA). The solid parts were positive for CK5/6 and most interestingly, also expressed AR but not CK7, PAP or PSA. The stroma also showed strong staining for AR but not for the other markers applied. To our knowledge this is the first report on AR expression in this benign polyp. Our findings confirm the view that tubulosquamous polyp of the vagina is derived from paraurethral Skene's gland.

Abstract
Vaginal tumours are rare, and Brenner tumour is one of the most infrequent vaginal lesions. Brenner tumour is a transitional tumour that typically arises in the ovaries. Some cases have been reported in the broad ligament, uterus and paratesticular structures. Only five cases have been reported in the vagina. We report a sixth case and discuss the histogenesis of this tumour, as well as the differential diagnosis with the mixed tumour of the vagina.

Abstract
We report 10 cases of a morphologically distinct vaginal polyp which has hitherto not been characterized. The polyps occurred in women aged 39 to 78 years (most were postmenopausal) and were from 1.0 to 3.0 cm. Most of whose location is known to us were in the upper vagina. Histologically, all the polyps were remarkably similar and composed of well-circumscribed expansile nests of epithelial cells embedded in a hypocellular fibrous stroma. The epithelial elements, which were morphologically bland, were predominantly glycogenated or nonglycogenated squamous in type but small tubules were present at the periphery of some of the nests in all cases. Some of the squamous nests exhibited central necrosis with or without calcification and, in 3 cases, some contained keratin pearls. In 3 cases, a few tubules unassociated with squamous elements were present. In 3 of 4 cases tested, the cells lining the tubules were positive with prostatic acid phosphatase and in 2 of 4 with prostate-specific antigen. The epithelial elements reacted with broad-spectrum cytokeratins and cytokeratin 7 but the mesenchymal component was negative. The squamous elements were estrogen receptor positive and the mesenchymal component estrogen and progesterone receptor positive. The histologic features of this polyp, which we term "tubulo-squamous polyp of the vagina," are constant and distinctive and differ from other polyps and from mixed tumor of the vagina. Several cases reported in the literature as vaginal mixed tumor or Brenner tumor are likely examples of this entity. Possible theories of histogenesis include a Mullerian origin, derivation from mesonephric remnants or derivation from urogenital sinus-derived epithelium. Positive staining in some cases with prostatic acid phosphatase and prostate-specific antigen raises the possibility of ectopic prostatic tissue, although the overall appearance is different from that entity, or derivation from paraurethral Skene glands, the female equivalent of prostatic glands in the male.

Abstract
Extraovarian Brenner tumors (BT) are very rare. We report such a tumor that was an intracavitary polyp in the uterus of a 63-year-old woman. The differential diagnosis included a pure transitional cell tumor, a mixed mullerian tumor, and a uterine tumor resembling an ovarian sex cord tumor. The histogenesis of BT remains controversial; in this particular case the location of the BT suggests a mullerian origin.
