Abstract
OBJECTIVE To present a recent clinical case of Skene's gland carcinoma and review all published literature of Skene's gland malignancy with associated treatment and outcomes. METHODS We review a new case of metastatic Skene's gland adenocarcinoma. We then performed a systematic search of PubMed and Ovid-Medline through December 2021 and retrieved English language articles for review. Peer-reviewed articles were deemed eligible if they included patients with Skene's gland malignancy. Reports were reviewed for pathologic accuracy, patient characteristics, clinical presentation, tumor pathology, treatment and outcome. RESULTS We reviewed 211 articles and included 15 cases from 1974 to 2022. The median patient age was 71 years (range 46-88). The most common presentation was an asymptomatic periurethral or urethral lesion in five cases (33.3%), followed by hematuria or vaginal bleeding in three patients (20.0%). In eight cases, a prostate-specific antigen was measured and found to be elevated, range 0.8-60.8 ng/mL. Treatment approaches varied and included local excision in eight cases, radical surgical resection in two cases, radiation therapy in two cases, and adjunctive androgen deprivation therapy in one case. Pathology was consistent with adenocarcinoma resembling prostate in all cases. In all cases tested, prostate-specific antigen normalized after definitive therapy of any type. Median follow up was 11.5 months, and there were no cases of recurrence or mortality secondary to Skene's gland adenocarcinoma. CONCLUSION There are 15 published cases of a Skene's gland malignancy, all adenocarcinoma resembling prostate. Local excision is most often utilized for treatment, with androgen deprivation therapy emerging as a new treatment consideration.

Desouki MM, Fadare O. Primary adenocarcinomas of the vulva and related structures: An enigmatic and diverse group of tumors ✰. Semin Diagn Pathol 2020; 38:71-84. [PMID: 33032903 DOI: 10.1053/j.semdp.2020.09.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 09/10/2020] [Accepted: 09/10/2020] [Indexed: 12/18/2022]
Abstract
Approximately half of adenocarcinomas that involve the vulva are secondary, either through direct extension or metastases from elsewhere. Primary vulvar adenocarcinomas are rare and encompass a diverse array of neoplasms that are nominally classified based on the presumed tissue or organ of origin, the tumoral phenotype, or both. In this review, we summarize the clinicopathologic features of adenocarcinomas that originate from the vulva and related structures, including the terminal urethra. Adenocarcinomas of this region encompass lesions that are defined by their primary site (such as adenocarcinomas of the Bartholin gland, which by definition must be in the region of the Bartholin gland), histomorphology and immunophenotype (such as clear cell carcinoma and adenocarcinoma of intestinal [cloacogenic] type), or both (such as adenocarcinoma of skene gland origin, which is associated with that specific organ but which also displays a distinctive phenotype that is similar to the phenotype of high grade prostatic adenocarcinoma). Other types, such as mammary-type adenocarcinomas, are presumed to originate from the putative mammary-like glands of the vulva and display a spectrum of pathologic features that are similar to their mammary counterparts. Similarly, vulvar carcinomas of sweat gland origin are pathologically similar to their counterparts in the non-vulvar skin and include a variety of cutaneous adnexal-type malignancies such as apocrine adenocarcinoma and eccrine adenocarcinoma. Some tumors, such as adenoid cystic carcinoma, may represent a Bartholin gland adenocarcinoma, a carcinoma of sweat gland origin, or a carcinoma arising from extramammary Paget disease (EMPD), depending on the context. Invasive carcinomas of various types have been reported in 7-12.7% of EMPD, and these are likely the most common primary glandular malignancy of the vulva. Occasional vulvar adenocarcinomas have been reported to be HPV-associated, although this association has not been established for the broader group of vulvar adenocarcinomas. Rare adenocarcinomas are not classifiable by the aforementioned nosologic scheme, and are designated as vulvar adenocarcinoma NOS.

Abstract
Primary urethral adenocarcinomas are very rare neoplasms accounting for <10% of all urethral carcinomas. Site of their origin is unclear, but they seem to arise from Skene's paraurethral glands, which is the female homologue of the male prostate. The aim of this article is to report the first case of Skene's gland adenocarcinoma in which a molecular genetic profiling was performed. The patient was a 73-year-old woman with a polypoid lesion sized 3 × 2 cm located at the interface between the bladder neck and the proximal urethra. Transurethral resection was performed and small tissue fragments with positive margins were obtained. Histology revealed an epithelial neoplasm consisting of cribriform structures located in the subepithelial connective tissue of the bladder wall and proximal urethra. The lesion showed positive immunohistochemical staining with prostate specific antigen, prostatic acid phosphatase, NKX3.1, and alpha-methylacyl-CoA racemase. Using the Illumina TruSight Tumor 170 next-generation sequencing assay, a mutation and loss of heterozygosity of the phosphatase and tensin homologue (PTEN) gene was detected. No fusion in any of the examined genes was found using this assay as well as FusionPlex Solid Tumor Kit and FusionPlex Sarcoma kit assays from ArcherDX. Given the rarity of Skene's gland adenocarcinoma, it is uncertain whether the same grading and prognostic criteria that are currently used for prostatic cancer apply here as well. It is also unclear what treatment strategy should be applied, but according to the available literature, it seems that local excision or wide surgical resection could represent sufficient therapeutic modalities.

Abstract
OBJECTIVE To determine if adenocarcinoma of the Skene's glands in women, which has a histological and immunohistochemical appearance similar to prostate cancer, can be evaluated and managed with the same tools we use for prostate cancer. METHODS Serum prostate-specific antigen kinetics, 3D multiparametric (MP) magnetic resonance imaging (MRI), fluciclovine F-18 positron emission tomography (PET), and androgen deprivation therapy (ADT) were employed in a case of Skene's gland adenocarcinoma. RESULTS The 3D MP MRI clarified the anatomy of the primary lesion and fluciclovine F-18 PET significantly improved our ability to stage the tumor prompting pelvic lymph node dissection that may have otherwise not been performed. ADT resulted in a significant impact on prostate-specific antigen kinetics despite the patient having a testosterone level in the normal range for a postmenopausal woman. CONCLUSION Despite the rarity of Skene's gland adenocarcinoma, we can employ many of the tools at our disposal for the evaluation and management of prostate cancer to benefit the women found to have this malignancy.

Prognostic and diagnostic role of PSA immunohistochemistry: A tissue microarray study on 21,000 normal and cancerous tissues. Oncotarget 2019; 10:5439-5453. [PMID: 31534629 PMCID: PMC6739211 DOI: 10.18632/oncotarget.27145] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Accepted: 07/17/2019] [Indexed: 12/19/2022] Open
Abstract
To assess the prognostic and diagnostic utility of PSA immunostaining, tissue microarrays containing 17,747 prostate cancers, 3,442 other tumors from 82 different (sub) types and 608 normal tissues were analyzed at two different antibody concentrations (1:100 and 1:800). In normal tissues, PSA expression was limited to prostate epithelial cells. In prostate cancers, PSA staining was seen in 99.9–100% (1:800–1:100) primary tumors, 98.7–99.7% of advanced recurrent cancers, in 84.6–91.4% castration resistant cancers, and in 7.7–18.8% of 16 small cell carcinomas. Among extraprostatic tumors, PSA stained positive in 0–3 (1:800-1:100) of 19 osteosarcomas, 1-2 of 34 ovarian cancers, 0-2 of 35 malignant mesotheliomas, 0–1 of 21 thyroid gland carcinomas and 0–1 of 26 large cell lung cancers. Reduced staining intensity and loss of apical staining were strongly linked to unfavorable tumor phenotype and poor prognosis (p
< 0.0001 each). This was all the more the case if a combined “PSA pattern score” was built from staining intensity and pattern. The prognostic impact of the “PSA pattern score” was independent of established pre- and postoperative clinico-pathological prognostic features. In conclusion, PSA immunostaining is a strong prognostic parameter in prostate cancer and has high specificity for prostate cancer at a wide range of antibody dilutions.

Abstract
PURPOSE Urethral carcinoma is among the rarest neoplasias of the genitourinary tract and its origin is unclear. Prostate-specific antigen (PSA) is considered an evidence of origin from Skene's glands. We considered the origin from these glands in PSA negative cases. MATERIAL AND METHODS We studied 3 patients with urethral carcinoma surgically treated. The surgical specimens were examined including cytochemical and immunohistochemical stains. The possible origin of the tumors was based on a comparative study of normal Skene's glands from autopsies and noninvolved glands in periurethral tumors. RESULTS The gross findings and the microscopic examination of 2 adenocarcinomas, including the cytochemical and immunohistochemical studies, favor an origin from Skene's glands. CONCLUSIONS The origin from Skene's glands may be established in PSA negative cases. The establishment of this origin in a higher number of urethral carcinomas may have an impact on diagnostic and treatment strategies in the future.

Abstract
The discovery of prostate-specific antigen (PSA) was beset with controversy; as PSA is present in prostatic tissue and semen, it was independently discovered and given different names, thus adding to the controversy. In this review we document the early research in this field to describe the chronology of the discovery of PSA. Using a comprehensive Medline search of the historical aspects of PSA, all relevant papers were reviewed; communication with the scientists involved in the discovery of PSA was an invaluable contribution. In 1960, Flocks was the first to experiment with antigens in the prostate and 10 years later Ablin reported the presence of precipitation antigens in the prostate. In 1971, Hara characterized a unique protein in the semen fluid, gamma-seminoprotein. Li and Beling, in 1973, isolated a protein, E1, from human semen in an attempt to find a novel method to achieve fertility control. In 1978, Sensabaugh identified semen-specific protein p30, but proved that it was similar to E1 protein, and that prostate was the source. In 1979, Wang purified a tissue-specific antigen from the prostate ('prostate antigen'). PSA was first measured quantitatively in the blood by Papsidero in 1980, and Stamey carried out the initial work on the clinical use of PSA as a marker of prostate cancer. Thus the discovery of PSA is interesting and surrounded by controversy. Although the credit for purifying PSA goes to Wang, other eminent scientists published research on this antigen. The initial work on PSA in semen was to asses its properties as a forensic marker for rape victims, but soon its potential as a marker for prostate cancer became evident.

Abstract
An 88-year-old woman presented with gross hematuria and a 3-cm periurethral mass. Biopsy revealed an adenocarcinoma resembling prostatic adenocarcinoma; the tumor cells were positive for keratin and prostate-specific antigen. The serum level of prostate-specific antigen was elevated; the carcinoembryonic antigen and CA-125 serum levels were normal. One year after external beam radiotherapy, the patient is without evidence of disease. This is the sixth case of a urethral prostatic-type adenocarcinoma, tumors that are most likely of Skene's gland origin.

Abstract
Severe acute respiratory syndrome (SARS) is an infectious condition caused by the SARS-associated coronavirus (SARS-CoV), a new member in the family Coronaviridae. To evaluate the lung pathology in this life-threatening respiratory illness, we studied postmortem lung sections from 8 patients who died from SARS during the spring 2003 Singapore outbreak. The predominant pattern of lung injury in all 8 cases was diffuse alveolar damage. The histology varied according to duration of illness. Cases that were 10 or fewer days in duration demonstrated acute phase diffuse alveolar damage (DAD), airspace edema, and bronchiolar fibrin. Cases with a time course greater than 10 days showed organizing phase DAD, type II pneumocyte hyperplasia, squamous metaplasia, multinucleated giant cells, and acute bronchopneumonia. In acute DAD, pancytokeratin staining was positive in hyaline membranes along alveolar walls and highlighted the absence of pneumocytes. Multinucleated cells were shown to be both type II pneumocytes and macrophages by pancytokeratin, TTF-1, and CD68 staining. SARS-CoV RNA was identified by RT-PCR in 7 of 8 cases in fresh autopsy tissue and in 8 of 8 cases in formalin-fixed, paraffin-embedded lung tissue including the one negative case in fresh tissue. Understanding the pathology of DAD in SARS patients may provide the basis for therapeutic strategies. Further studies of the pathogenesis of SARS may reveal new insights into mechanisms of DAD.

Abstract
Prostate-specific antigen (PSA or hK3) is a glandular kallikrein with abundant expression in the prostate that is widely used to detect and monitor prostate cancer (PCa), although the serum level is frequently elevated also in benign and inflammatory prostatic diseases. PSA testing is useful for early detection of localized PCa and for the detection of disease recurrence after treatment. However, PSA has failed to accurately estimate cancer volume and preoperative staging. There is no PSA level in serum that definitively distinguishes men with benign conditions from those with prostate cancer, although PCa is rare in men with PSA levels in serum < 2.0 ng/ml. This prompted searches for enhancing parameters to combine with PSA testing, such as PSA density, PSA velocity, and age-specific reference ranges. Due to the protease structure, PSA occurs in different molecular forms in serum and their concentrations vary according to the type of prostatic disease. Human glandular kallikrein 2 (hK2) is very similar to PSA, but expressed at higher levels in prostate adenocarcinoma than in normal prostate epithelium. Blood testing for hK2 combined with different PSA forms improves discrimination of men with benign prostatic disease from those with prostate cancer. Many data have also been reported on the extra-prostatic expression of both PSA and hK2, and it is now believed that they may both have functions in tissues outside the prostate.

Abstract
We report four examples of prostatic tissue occurring in the uterine cervix of patients aged 22, 25, 31, and 77 years. Three were incidental findings in loop excisions (two patients) and cone biopsy (one patient) of the cervix for high-grade squamous dysplasia. One presented as a cervical mass, clinically suspected to represent a fibroid. The prostatic tissue consisted of ducts and acini, some of which had papillary or cribriform patterns. Squamous metaplasia was prominent in all cases. No Wolffian duct tissue was present. The glandular epithelium in all cases was positive for prostatic acid phosphatase and prostate-specific antigen. High molecular weight keratin, performed in two cases, highlighted basal cells in a manner similar to the normal prostate. These unusual cases, only one of which is documented previously, further complicate the often-challenging area of interpretation of benign glandular lesions of the cervix. The unusual phenomenon of ectopic prostate tissue in general is reviewed.

Abstract
Although prostate-specific antigen (PSA) is the most valuable tumor marker for the diagnosis and management of prostate carcinoma, it is widely accepted that PSA is not prostate specific. Numerous studies have shown that PSA is present in some female hormonally regulated tissues, principally the breast and its secretions. In this review, we summarize the findings of PSA in the breast, and focus on its potential for clinical applications in breast disease. PSA is produced by the majority of breast tumors and is a favorable indicator of prognosis in breast cancer. Low levels of PSA are released into the female circulation, and while the level of serum PSA is elevated in both benign and malignant breast disease, the molecular form of circulating PSA differs between women with and without breast cancer. These findings indicate that PSA may have potential diagnostic utility in breast cancer. PSA may also have a clinical application in benign breast disease, as both the level and molecular form of PSA differ between Type I and II breast cysts. High levels of PSA have been reported in nipple aspirate fluid (NAF) and recent studies have shown that the concentration of PSA in NAF is inversely related to breast cancer risk, indicating that NAF PSA may represent a clinical tool for breast cancer risk assessment. Thus, PSA represents a marker with numerous potential clinical applications as a diagnostic and/or prognostic tool in breast disease.

Abstract
PURPOSE Urethral adenocarcinoma is a rare malignancy whose origin remains controversial. The monoclonal antibody mAbDas1 (formerly 7E12H12) was developed against a unique colonic epithelial epitope and is reactive in areas of intestinal metaplasia. Recently the antibody was shown to react in cystitis glandularis as well as adenocarcinoma of the bladder, suggesting that cystitis glandularis may be the precursor of bladder adenocarcinoma. We examined urethral adenocarcinomas and benign urethral specimens using mAbDas1 to determine whether it could provide insight into their histogenesis. MATERIALS AND METHODS Archival tissue from 12 cases of primary female urethral adenocarcinoma and urethral specimens of inflamed urethral mucosa, urethritis glandularis and transitional cell carcinoma was studied. Immunohistochemical analysis of formalin fixed, paraffin embedded archival tissue was done using the monoclonal antibody mAbDas1. Tumors were also evaluated with a prostate specific antigen (PSA) polyclonal antibody as previous studies have noted PSA reactivity in these tumors. RESULTS Of the 12 cases 9 were columnar/mucinous adenocarcinoma, 2 clear cell adenocarcinoma and 1 a cribriform pattern resembling adenocarcinoma of the prostate. All columnar/mucinous adenocarcinomas reacted positively (6 strongly and 3 focally) with the mAbDas1 antibody but did not react with the PSA antibody. The tumor with a cribriform pattern reacted strongly with PSA but did not react with mAbDas1. The 2 clear cell adenocarcinomas did not react with either antibody. The benign urethral specimens demonstrated strong reactivity to the mAbDas1 antibody in areas of urethritis glandularis but normal and inflamed urethral mucosa and transitional cell carcinoma did not react. CONCLUSIONS Primary adenocarcinoma of the female urethra arises from more than 1 tissue of origin. Columnar/mucinous adenocarcinomas of the female urethra and urethritis glandularis demonstrate consistent reactivity with the mAbDas1 antibody, suggesting that these tumors arise from glandular metaplasia analogous to the potential histogenesis previously demonstrated in the bladder. PSA reactivity occurred in 1 tumor with a cribriform pattern and likely represents origin from Skene's glands. Clear cell adenocarcinomas did not react with either antibody, suggesting a third possible pathway in the development of this rare subset of adenocarcinomas.

Abstract
Because of histological similarities between nephrogenic adenomas and clear cell adenocarcinomas of the urinary tract, there is the potential for diagnostic confusion between these two entities. The histopathologic features of 13 nephrogenic adenomas and five clear cell adenocarcinomas of the urethra and urinary bladder are compared in this report, and detailed immunohistochemical staining profiles are provided for these tumors. Only 2 of the 13 nephrogenic adenomas contained clear cells, and these constituted less than 10% of the lesions. In contrast, four of the five clear cell adenocarcinomas contained prominent areas with clear cells. Nephrogenic adenomas generally showed only mild cytologic atypia, whereas four of the five clear cell adenocarcinomas showed severe atypia. A single mitotic figure was identified in only two of the nephrogenic adenomas, whereas the mitotic rate in the clear cell adenocarcinomas ranged from 2 to 14 per 10 high-power fields. None of the nephrogenic adenomas showed evidence of necrosis, but focal necrosis was noted in four of the five clear cell adenocarcinomas. In general, the nephrogenic adenomas and clear cell adenocarcinomas showed negative to weak staining with CK903 but strong staining with AE1, AE3, and Cam 5.2. Variable staining was observed with Brst-3 and antibodies to S-100, CEA (monoclonal and polyclonal), LeuM-1, and CA19.9. Nephrogenic adenomas and clear cell adenocarcinomas were all negative for prostate-specific acid phosphatase (PSAP), prostate-specific antigen (PSA), and estrogen and progesterone receptors (except for two nephrogenic adenomas, which showed only focal weak staining for estrogen receptor). Neither bcl-2 nor c-erbB-2 staining was able to discriminate between the tumors. However, strong staining for p53 was noted in each clear cell adenocarcinoma and in none of the nephrogenic adenomas. MIB-1 positivity in nephrogenic adenomas ranged from 0 to 13 (average of 5.5) per 200 cells, whereas the positive range for clear cell adenocarcinomas was 33 to 70 (average of 47) per 200 cells. In summary, histopathologic features that favor clear cell adenocarcinoma over nephrogenic adenoma include a predominance of clear cells, severe cytological atypia, high mitotic rate, necrosis, high MIB-1 positivity, and strong staining for p53.

Abstract
The case of a 46-year-old women with well-differentiated adenocarcinoma of the female prostate (Skene's paraurethral glands and ducts) with inguinal metastases is reported. Besides adenocarcinomatous structures, also more solid parts of the tumor and anaplastic regions with dark cells were found on histological examination. Clear cancerous cells were typical for glandular and solid tumor parts. The cancerous cells showed distinct immunohistochemical positivity of prostate specific antigen (PSA) and prostate (specific) acid phosphatase [P(S)AcP]. These are the first published results of electron microscopic examination of formalin fixed tissue showing the ultrastructure of female prostate carcinoma, comparable to that of the male prostate carcinoma. In the female, similar to the male, the prostate carcinoma probably originates from the secretory (luminal) cells of the female prostatic glands.

Abstract
Mouse monoclonal anti-urine protein 1 antibody and the biotin-streptavidin-peroxidase technique were used for the immunohistochemical demonstration of human protein 1 in prostatic tissue of both sexes. In the female prostate (Skene's gland), like the male prostate, high expression of human protein 1 was observed on the luminal surface and in the apical cytoplasm of secretory cells of prostatic glands, as well as on the luminal surface of the epithelium of the large ducts of the female prostate and urethra. Expression was also found in the membranes of secretory and basal cells of the glands, in membranes of the urethral uroepithelium and of the female prostate ducts, in the content of glands and ducts, as well as in vascular endothelium and smooth muscle. Human protein 1 (urine protein 1) expression in the secretory cells of the male and female prostate and its incorporation into the surface of cells lining the lumina of the female urethroprostatic complex is indicative not only of the secretory role of protein 1 but also of its potential protective properties operative in shielding the uroepithelium from the aggressive urinary environment. All genito-urinary tissue, and especially the female prostate, were found to be a potential source of urine protein 1 (human protein 1), refuting the notion held so far that it is exclusively the genito-urinary prostatic tissue of the male that participates in its production. The corresponding immunohistochemical distribution of human protein 1 in the same structures of the male and female prostate provides yet another analogous functional-morphological parameter of prostatic tissue in both sexes and further evidence supporting the non-vestigial concept of the prostate in the female.

Abstract
A study of cancer incidence in a cohort of 597 women with Turner syndrome (TS) and a virtually complete follow-up is presented. The cohort was established from the Danish Cytogenetic Register. Information on cancer incidence was obtained from the Danish Cancer Registry and compared with the expected number calculated from the age-, period- and site-specific cancer rates for Danish women. A total of 21 neoplasms was observed, of which 13 occurred more than 1 year after diagnosis of TS, corresponding to a relative risk of cancer of 1.1. Wilms' tumour was the only identified childhood cancer. No case of gonadoblastoma or dysgerminoma was identified in the 29 women with a Y chromosome or in the women in whom no Y chromosome material was detected by standard cytogenetic methods, suggesting that the risk of ovarian germ cell tumours may be lower than previously estimated. Colon cancer was observed in five patients (relative risk 6.9, 95% confidence interval 2.2-16.2). Further studies are needed to assess whether colon cancer in TS is related to Turner-associated genes on the sex chromosome(s).

Abstract
Immunohistochemical detection of prostate specific antigen (PSA) in metastases of adenocarcinomas is widely used as an aid to identify the prostatic origin of metastatic cells. However, on the one hand, PSA may not be expressed in some poorly differentiated prostatic carcinomas, while on the other, PSA immunoreactivity has been found in small amounts in non-prostatic tissues. The aim of the current study was to evaluate the prevalence of PSA immunoreactivity in normal non-prostatic tissues and in breast carcinoma. PSA was localized by immunohistochemistry with four commercial antibodies in 34 different normal human tissues, and in 15 ductal and seven apocrine breast carcinomas. Concentrations of PSA in tissue homogenates of prostate and nine non-prostatic tissues from autopsied subjects were measured by a two-site immunoradiometric assay. Weak PSA immunoreactivity was found by immunohistochemistry in kidney, parotid gland and pancreatic tissues. Variable PSA immunoreactivity was seen in three cases of ductal (20%) and two cases of apocrine breast carcinoma (28%). No consistent PSA immunoreactivity was found in homogenates of non-prostatic tissues by the immunoradiometric assay. We conclude that PSA is a quite specific marker of prostatic tissue. However, there are some non-prostatic neoplastic and normal tissues that express PSA. Therefore, a definite diagnosis of metastasis of prostatic origin cannot be made on the basis of immunolabelling for PSA alone.

Abstract
A case of clear cell adenocarcinoma arising from the female urethra is described. Histologically, solid and glandular areas consisted of clear cells. The tumor cells stained positively with antibodies to prostate-specific antigen and prostatic acid phosphatase, suggesting that the clear cell adenocarcinoma arises from the female paraurethral duct, rather than embryonic remnants.

Abstract
An autopsy case of adenocarcinoma of Skene's paraurethral gland co-incident with renal cell carcinoma is described. The adenocarcinoma showed distinct prostate specific antigen and prostate specific acid phosphatase pointing to the equivalence between the male prostate and Skene's paraurethral glands and ducts. Skene's gland are the homologue of the prostate in females and tumours arising from them are immunohistochemically similar to male prostate carcinoma.

Abstract
Urachal remnants were obtained at autopsy from 10 males and 15 females in order to determine whether prostatic specific antigen (PSA) is present in that tissue. Immunohistochemical staining was carried out using a commercially available antibody to PSA. Four cases (three females and one male) showed focal positive reaction of PSA, predominantly in narrow glandular structures of metaplastic origin. Therefore, it cannot be excluded that PSA might occur in urachal adenocarcinomas. PSA-staining is evidently not confined exclusively to tissue originating in the prostate.
