Abstract
Ten percent of all women have pigmented vulvar lesions. Fortunately, most of these are benign but 1% of all melanomas in women affect the vulva. While the mortality rate of cutaneous melanoma has dropped by 7% annually during the last 5 years, the prognosis of vulvar melanoma remains dismal: the 5-year overall survival rate is 47% compared with 92% for cutaneous melanoma. The current evidence suggests that this likely results from a combination of delayed diagnosis and different tumor biology, treatment strategies, and treatment response. Although many landmark trials on checkpoint inhibitors included mucosal and vulvar melanomas, the results were often not reported separately. Post-hoc analyses indicate overall response rates between 19 and 37% for checkpoint inhibitors. A recently published retrospective study on vulvar melanomas suggests an objective response in 33.3% with a similar safety profile to cutaneous melanoma. Tyrosine kinase inhibitors may be considered in recurrent disease if a c-KIT mutation is present.

Abstract
Mucosal melanoma is a rare tumor with aggressive biological behavior and poor prognosis. Diagnosis is often performed at an advanced stage when the lesions become symptomatic. Although dermoscopy and reflectance confocal microscopy (RCM) are widely used techniques for the diagnosis of cutaneous tumors, their use for mucosal lesions is not well established, probably because the latter are rarer. The objective of this study was to evaluate current literature on these imaging techniques for mucosal melanoma. We searched in PubMed and Cochrane databases all studies up to October 2020 dealing with dermoscopy, RCM, and mucosal melanoma. We found that the most relevant dermoscopic features were structureless pattern and/or the presence of multiple colors. RCM examination mainly showed numerous basal hyper-reflective dendritic cells and loss of normal architecture of the papillae of the lamina propria. Although diagnostic algorithms have been proposed for both techniques, the limit of these methods is the absence of large studies and of standardized and shared diagnostic criteria.

Abstract
The male and female external genital regions are anatomical areas in which various types of skin disorders may occur. Although most of these conditions can be diagnosed by means of clinical examination and an accurate medical history, in most cases further investigations with time-consuming and/or invasive procedures are needed in order to reach the correct diagnosis. Dermoscopy, as a modern non-invasive tool, is able to better diagnose pigmented and non-pigmented skin tumours along with various inflammatory and infectious skin and appendage disorders. The aim of this paper was to provide a review of the use of dermoscopy in genital disorders based on published data and to include personal experience gained from real life, focusing on any possible gender difference and whether disease mucosal/semimucosal dermoscopy features may differ from those observed on the skin. In conclusion, genital dermoscopy should always be considered during clinical inspection in order to enhance the diagnosis or to rule out those conditions that may look similar but that show a different dermoscopy pattern, thus narrowing down the differential diagnoses and avoiding unnecessary invasive investigations.

Abstract
BACKGROUND Vulvar melanoma (VM) is rare and is often diagnosed late. Dermoscopy may aid in its recognition, differentiating VM from other more common vulvar lesions, such as melanosis and naevi. However, little is known about the dermoscopic features of thin VM. AIM To retrospectively analyse a series of histopathologically diagnosed thin VMs and to highlight their most suggestive dermoscopic features. METHODS A multicentre, retrospective study was conducted, including histopathologically proven thin VMs, either intraepidermal or with Breslow thickness ≤ 0.5 mm, diagnosed during the period 2016-2018. We particularly focused on their dermoscopic characteristics to highlight the most suggestive dermoscopic diagnostic clues. RESULTS In total, 14 cases of early-stage VM were included, in women with a mean age at diagnosis of 64.86 years. The most frequently affected sites were the labia minora. Of these, 11 cases were unifocal. Dermoscopy most often revealed structureless areas, grey globules and areas, irregular black-brown dots, blue and white structures, and red areas. CONCLUSIONS In our experience, early-stage VM often exhibits dermoscopic features that are more typical of thicker cutaneous melanomas. Dermoscopy may provide useful clues for the prompt diagnosis of thin VM.

Abstract
Vulvar melanoma is a rare and deadly cancer in women, and the prognosis is often poor. There are limited studies on the dermoscopic features of vulvar melanoma. Described criteria include the presence of blue, gray, or white colors. Herein we present the clinical and dermoscopic characteristics of a hypopigmented and heavily pigmented nodule in a 92-year-old and an 80-year-old woman. Dermoscopy in the former revealed structureless milky-red to white areas, remnants of brown pigmentation at the base and polymorphic vessels, while the latter displayed structureless blue-gray areas with black dots and peripheral lines at the base. In both cases, histopathology revealed a stage III melanoma. Our two cases along with a review of the literature suggest that the dermoscopic features described for diagnosing cutaneous nodular melanoma, apply also for vulvar melanoma. Clinicians should always raise the suspicion if observing plaques or nodules with a dermoscopic polymorphic vascular pattern and blue-black color on the genitals of postmenopausal women.

Abstract
Dermoscopy is an aiding method in the visualization of the epidermis and dermis. It
is usually used to diagnose melanocytic lesions. In recent years, dermoscopy has
increasingly been used to diagnose non-melanocytic lesions. Certain vascular
structures, their patterns of arrangement and additional criteria may demonstrate
lesion-specific characteristics. In this review, vascular structures and their
arrangements are discussed separately in the light of conflicting views and an
overview of recent literature.

Abstract
BACKGROUND The dermoscopic features of vulvar melanosis lesions are well known. To our
knowledge, there are only a few case reports about dermoscopic features of
pigmented genital lesions in male patients. OBJECTIVE To evaluate dermoscopic and clinical characteristics of benign lesions of the
genital area in both males and females, and to assess the distinguishing
dermoscopic criteria of vulvar melanosis and atypical melanocytic nevi of
the genital type. METHODS 68 patients with pigmented genital lesions were included in this
observational study (28 male and 40 female). A punch biopsy was taken from
all pigmented lesions and histopathological examination was performed on all
specimens. RESULTS We histopathologically diagnosed: genital melanosis in 40 lesions, atypical
melanocytic nevi of the genital type in 15 lesions, melanocytic nevi in 9
lesions, seborrheic keratosis in 4 lesions. The most frequent locations were
the glans penis (19 patients, 67.9%) in males and the labia minora (19
patients, 47.5%) in females. The mean age of patients with atypical nevi
(28,6 ± 11,36) was significantly lower than the mean age of patients with
genital melanosis (47,07 ± 15,33). CONCLUSIONS Parallel pattern is prominent in genital melanosis, ring-like pattern is only
observed in genital melanosis. Most pigmented lesions on the genital area
are solitary. Blue-white veil and irregular dots are only observed in AMNGT.
According to these results, we propose that histopathological examination is
performed, especially if blue-white veil and irregular dots are found by
dermoscopy.

Abstract
BACKGROUND The dermoscopic patterns of pigmented skin tumors are influenced by the body site. OBJECTIVE To evaluate the clinical and dermoscopic features associated with pigmented vulvar lesions. METHODS Retrospective analysis of clinical and dermoscopic images of vulvar lesions. The χ² test was used to test the association between clinical data and histopathological diagnosis. RESULTS A total of 42 (32.8%) melanocytic and 86 (67.2%) nonmelanocytic vulvar lesions were analyzed. Nevi significantly prevailed in younger women compared with melanomas and melanosis and exhibited most commonly a globular/cobblestone (51.3%) and a mixed (21.6%) pattern. Dermoscopically all melanomas showed a multicomponent pattern. Melanotic macules showed clinical overlapping features with melanoma, but their dermoscopic patterns differed significantly from those observed in melanomas. CONCLUSION The diagnosis and management of pigmented vulvar lesions should be based on a good clinicodermoscopic correlation. Dermoscopy may be helpful in the differentiation of solitary melanotic macules from early melanoma.

Abstract
BACKGROUND The dermoscopic criteria for benign and malignant lesions on the vulva are not well established due to the lack of large series of such lesions. Melanoma should always be included in the differential diagnosis of pigmented lesions on the vulva especially when they are wide, or of recent onset. Elsewhere on the skin dermoscopy plays an important role in the selection of suspicious pigmented lesions, as well as in the selection of the best site to perform the biopsy. OBJECTIVES To analyse the dermoscopic patterns observed in pigmented lesions of the vulva. METHODS We analysed a nonselected consecutive series of 68 histopathologically proven cases comprising five melanomas, 16 naevi, 20 lentigos, 12 benign vulval melanoses, 11 cases of postinflammatory pigmentation, three pigmented cases of usual vulval intraepithelial neoplasia (VIN) and one seborrhoeic keratosis seen at our institution. The dermoscope was covered by translucent disposable food wrap and/or antibacterial gel to prevent possible transmission of infections. Descriptive statistics were performed using multiple correspondence analysis. RESULTS The parallel (37%), ring-like (9%), homogeneous (22%), globular-like (13%) and reticular-like (6%) patterns were observed on benign lesions (naevi, lentigo, vulval melanosis and postinflammatory pigmentation). The cerebriform pattern (6%) was observed only on VIN and seborrhoeic keratosis. The multicomponent pattern (6%) was associated with melanoma (60%). In cases of melanoma we also occasionally observed an irregular pattern, a whitish or blue-whitish veil, irregularly distributed dots and globules and atypical vascular pattern. Using multiple correspondence analysis, we designed a new algorithm for the early detection of vulval melanomas. CONCLUSIONS Dermoscopy can play a role in the noninvasive classification of vulval melanosis. However, further studies of larger collaborative series are needed to validate our vulval melanoma diagnostic algorithm. VIN and seborrhoeic keratosis share the same dermoscopic features and biopsy should be considered for seborrhoeic-like keratosis. In case of doubt pathological examination of a biopsy remains mandatory.

Abstract
BACKGROUND Eruptive epidermolysis bullosa (EB) naevi comprise a subset of melanocytic naevi with atypical features that characteristically occur in areas of former blistering in patients suffering from hereditary EB. OBSERVATION The case is reported of a girl who presented with pruritus, blistering and erosions of the vulval region. Clinical and immunopathological features were consistent with the diagnosis of childhood vulval pemphigoid. In the course of the disease, she developed an atypical melanocytic naevus on the left labium at a site of former blistering. Although its clinical and dermoscopic features resembled malignant melanoma, the lesion completely regressed clinically during the 24-month follow-up. CONCLUSION This is the first report describing the development of a melanocytic naevus at sites of blistering in an auto-immune subepidermal blistering disease in childhood. Our observation extends the spectrum of disorders, in addition to the group of congenital EB, in which 'eruptive' atypical melanocytic naevi may occur. Knowledge of this complication is important for appropriate management and follow-up and to avoid radical surgery.
