Review
Extracellular signals are normally presented to one surface of epithelial cells and to one end of neurons, and so neuronal and epithelial cell signaling is inherently polarized. Another aspect of signaling polarity is that receptors are often asymmetrically distributed on the surfaces of polarized cells. Recent evidence from studies of Caenorhabditis elegans shows that signaling polarity plays an important role in development. The underlying mesoderm induces the overlying ectoderm to form the vulva, and asymmetric distribution of the signal receptor on the basolateral surface of the epithelium is crucial for this signaling. In neurons, the localization of neurotransmitter receptors and ion channels at synapses allows neurons to be exquisitely sensitive to synaptic inputs. Exciting recent reports suggest that receptor localization to neuronal synapses and the basolateral membrane domains of epithelia may involve a common molecular mechanism involving localization by PDZ-containing proteins.

Gynecological sarcomas are rare and their location in the vulva and vagina has an incidence of 5% of all malignant neoplasms in the female genital tract. We present the case of a 54-year-old patient with a diagnosis of dermatofibrosarcoma protuberans in the vulva, an infrequent pathology with less than 60 cases reported worldwide in this anatomical location. Clinically, it is locally aggressive, due to the proliferation of spindle cells with pleomorphism and frequent mitotic figures infiltrating the reticular dermis and subcutaneous cellular tissue, giving rise to variable size tumors with high local recurrence rates. The first-line treatment is surgical excision of the tumor with Mohs micrographic surgery among other surgical techniques for complete circumferential peripheral and deep margin assessment. However, identification of carcinogenesis mechanisms where the chromosomal translocation t (17; 22) (q22; q13) is recognized, forming the COL1A1-PDGFB fusion gene, which participates in stimulating tumor cell proliferation, allowing treatment with tyrosine kinase inhibitors such as imatinib for neoadjuvant therapy of surgically unresectable tumors and local recurrences.

OBJECTIVE
To report the case of a patient diagnosed with ectopic mammary tissue in the vulva, and to conduct a literature review of the diagnosis, treatment and prognosis of this condition in that location.
MATERIALS AND METHODS
A 49-year-old patient who presented with a painful vulvar mass to a private intermediate complexity center in Bogotá, Colombia. The lesion was assessed on ultrasound and then surgically excised; histopathology showed ectopic mammary tissue with absence of malignancy. A search was conducted in the PubMed, Embase, Cochrane, LILACS and Scielo databases using the keywords “Vulva,” “Breast” and “Ectopic.” Case reports and case series of women with histopathology-confirmed mammary tissue in the vulva were included.
RESULTS
Overall, 184 titles were identified and, of these, 94 were ultimately included, for a total of 126 cases, with 57.9% being benign tumors, 95% in women under 50 years of age, and 42.06% being malignant tumors, 92% in women over 50 years of age. Diagnosis was made on the basis of the clinical findings, with ancillary diagnostic imaging, tumor markers and immunohistochemistry in some cases. Local excision was performed in 91% of cases with benign pathology and in 43% of cases with malignant pathology, with the diagnostic method being therapeutic.
CONCLUSIONS
Ectopic mammary tissue in the vulva must be considered as part of the differential diagnosis of vulvar masses, prognosis being different in pre and postmenopausal women. Further studies are needed to enhance the characterization of this condition and define the ideal course of treatment in terms of relapse and survival.

Ectopic mammary gland tissue in the vulva is an exceptionally rare disease. We present a case of a 62-year-old woman with a left vulvar mass of 30 years duration that progressively increased in size. The patient reported having pressure and discomfort, especially during movement. Surgical excision was performed, and a histopathological examination revealed a well-differentiated ectopic breast. We also review other cases of vulvar ectopic breast to further comprehend the characteristics of this rare disease. Clinicians and pathologists should always consider it as a differential diagnosis when presented with a vulvar mass.

INTRODUCTION
Vulva squamous cell carcinoma (VSCC) develops through two separate molecular pathways-one involving high-risk human papilloma virus infection (HPV-associated), and the other without HPV infection (HPV-independent) often involving TP53 mutation. HPV-associated VSCC generally has a better progression-free survival than HPV-independent VSCC. The aim of this study was to determine TP53 mutation status using immunohistochemistry, compare different methods of HPV detection and correlate both with survival in a retrospective cohort of 123 patients with VSCC.
MATERIAL AND METHODS
Immunohistochemistry for p53, Ki67 and p16 (a surrogate marker for HPV infection) was performed on formalin-fixed paraffin-embedded tissues from a cohort of surgically treated VSCC patients to identify molecular subtypes of VSCC. Presence of HPV infection was detected by HPV DNA PCR and HPV mRNA in situ hybridization (ISH). The Pearson chi-square test and multivariable Cox regression model were used to investigate the association of different parameters with progression-free survival and disease-specific survival (DSS), and Kaplan-Meier curves were used to show the association of different parameters with survival.
RESULTS
The results of p53 and p16 immunohistochemistry confirmed three VSCC subtypes associated with different prognosis. The TP53 mutation status was identified as an independent prognostic factor of worse progression-free survival (p = 0.024) after adjustment for FIGO stage. p16 immunohistochemistry, mRNA ISH, and DNA PCR had excellent concordance in terms of HPV detection. According to the multivariable Cox regression model, the presence of hrHPV mRNA correlated significantly with increased progression-free survival (p = 0.040) and DSS (p = 0.045), after adjustment for other confounders.
CONCLUSIONS
p53 and p16 immunohistochemistry stratify VSCC cohort into three subtypes with TP53mutated patients having the worst prognosis. The detection of hrHPV mRNA by ISH was an independent predictor of increased survival. Thus, the combined detection of p53 and HPV mRNA might improve risk stratification in VSCC.

Review
BACKGROUND
The term genitourinary syndrome of menopause was first used in 2014 by the North American Menopause Society and the International Society for the Study of Women's Sexual Health to describe conditions previously known as atrophic vaginitis, urogenital atrophy, or vulvovaginal atrophy. It is a complex, chronic, progressive condition characterized by a wide range of signs and symptoms affecting sexual function and the tissues of the urinary and genital tracts. The main cause of genitourinary syndrome of menopause is estrogen deficiency caused by ovarian removal or dysfunction. The most bothersome symptoms are vaginal dryness, decreased vaginal lubrication, and pain during penetration and intercourse. They all have a negative impact on the quality of life.
CONCLUSIONS
The main goal of treatment is to relieve the symptoms. Treatment modalities are pharmacological or non-pharmacological. The first-line treatment for mild to moderate symptoms is the use of personal lubricants and moisturizers, but the gold standard is estrogen replacement therapy. Hormone therapy may not be an option for women with hormone-dependent cancer.

Review
Paraganglioma is a neuroendocrine neoplasm, which is extremely rare in the vulva and only one case has been reported. Here we present a case of vulvar paraganglioma in a 48-year-old woman and a literature review. The patient found a lump located in the genitals below the symphysis pubis 3 months before presentation when she complained that the lump was increasing in size. A 3.2 cm x 2.3 cm x 1.5 cm nodule was excised from subcutaneous soft tissue in the vulva. Microscopy showed a diversity of cell morphologies and structures in the rich vascular network of the tumor separated the chief cells into round cell nests (Zellballen pattern). Some areas of the tumor presented epithelioid and spindle-shaped cells with increased cell density and indistinct structural characteristics. Hyaline degeneration of collagen fibers or mucoid degeneration was found in tumor interstitium. Immunohistochemical staining showed diffused expression of synaptophysin in the chief cells, focal expression of S-100 protein in the sustentacular cells and high expression of CD34 in the vascular components. Based on morphological and immunohistochemical results, a rare paraganglioma of the vulva was diagnosed.

Review
Fibroepithelial stromal polyps of vulva are the type of mesenchymal lesion that typically occurs in women of reproductive period. They are common, usually small and hystologically benign. Larger lesions are rare and likely arise from proliferation of mesenchymal cells within the hormonally sensitive subepithelial stromal layer of the lower genital tract. We present a case of 16 year old female with a giant polypoid lesion of the vulva localized on the right labium. The mass measure was 18×12×3 cm. Total surgical resection of the lesion was performed. Histopathological examination reported a fibroepithelial stromal polyp of the vulva. The patient showed no evidence of recurrence four years after the resection. Fibroepithelial polyps of the vulvar region are benign lesions that have a wide range of morphologic appearances and may be misinterpreted as malignant. Total excision is the best treatment options and histopathological examination is strongly recommended to rule out a malignant neoplasm.
