Abstract
Basal cell carcinoma accounts for 75% of skin cancers worldwide and is the most common malignancy in Caucasians. Since chronic ultraviolet exposure is the major risk factor for its development, sun-exposed areas such as the face are frequently affected. The gold-standard treatment is surgical excision. Radiotherapy may be considered in selected cases such as unresectable primary tumors. In some patients, when the risk of a significant functional/cosmetic deficit advises against both surgery and radiotherapy, target therapy (hedgehog pathway inhibitors) can be administered alone or in a neoadjuvant setting, to reduce the tumor size and make it eligible for surgery. Vismodegib as a neoadjuvant treatment before surgery has been investigated in a single, multicentre, open-label, phase II trial (VISMONEO); however, sonidegib has not yet been evaluated in this setting. We report the cases of two patients with locally advanced basal cell carcinoma of the face who achieved complete remission with sonidegib followed by a more limited surgical excision than would have been needed without target therapy.

Abstract
BACKGROUND Cutaneous vascular lesions (VLs) are benign or malignant processes involving blood and/or lymphatic vessels, usually readily diagnosed with dermoscopy. However, cases showing unclear clinical/dermoscopic findings may require further investigations. Line-field confocal optical coherence tomography (LC-OCT) is a new, non-invasive imaging technique displaying high resolution and deep penetration. The aim of this study was to describe the LC-OCT features of the most common benign and malignant VLs and to correlate them with histopathological substrates. METHODS Clinical, dermoscopic, LC-OCT and histopathological images of VLs were retrospectively collected. Detailed LC-OCT description and histopathological correlations were produced for different types of. VLs. RESULTS The study included 71 VLs belonging to 50 caucasian patients [31 (62%) females; median age 56.8 (30-83) years] study lesions included 25 cherry haemangiomas, 15 angiokeratomas, 10 thrombosed haemangiomas, 6 pyogenic granulomas, 5 venous lakes, 4 targetoid haemosiderotic haemangiomas, 4 Kaposi's sarcomas, and 2 extraungual glomus tumours. LC-OCT detected increased dermal vascularity, assuming different size and shape according to the particular type of VLs. LC-OCT criteria correlated well to established histopathologic findings. CONCLUSION The results of our preliminary observations indicates that in-vivo evaluation with LC-OCT may provide practical clues for the identification of the vascular nature of a lesion and its differential diagnosis.

Abstract
OBJECTIVE Eccrine porocarcinoma (EPC) is a malignant adnexal tumor accounting for about 0.005% of skin tumors. The standard treatment of EPC is the complete surgical excision of the primary lesion and of the clinically involved lymph nodes. There is limited evidence regarding the role of radiotherapy (RT) in managing EPC after surgery. Therefore, the aim of this multidisciplinary systematic review is to analyze the available evidence about postoperative RT in the curative treatment of EPC. MATERIALS AND METHODS A systematic search strategy was launched trough the main scientific databases including PubMed, Scopus and Cochrane. An additional manual search and a chain citation were performed about potentially relevant papers. The key words used for the search included "eccrine porocarcinoma", "porocarcinoma", "radiotherapy", "radiation therapy", "adjuvant radiotherapy" and "postoperative radiotherapy". RESULTS A total of 104 publications were identified and 14 papers were included in the final analysis. The only articles found on adjuvant RT in EPC were case reports published between 1996 and 2019. There was a slight female prevalence (57% female/43% male) with a mean age of 65 years (range 37-85). Head-and-neck region was the most frequently involved anatomical site followed by legs. CONCLUSIONS Adjuvant radiotherapy after surgical removal of EPC could be considered in cases with positive or close margins and in cases with unfavorable histological features. In view of limited literature data and the rarity of EPC the best treatment sequence should always be discussed within the frame of a multidisciplinary setting. ADVANCES IN KNOWLEDGE adjuvant radiotherapy after surgical removal of EPC could be considered in cases with positive or close margins and in cases with unfavorable histological features.

Abstract
Common primary cutaneous squamous cell carcinoma (CSCC) accounts for 20% of keratinocyte cancers that is usually successfully treated with surgery or radiotherapy. In a minority of cases, CSCC lesions may progress to locally advanced or metastatic disease that may be difficult to be treated causing significant morbidity and mortality. Chemotherapies and targeted therapy with anti-epidermal growth factor receptor antibodies have been used off-label in small studies and case reports of advanced CSCC, but data are scarce and response short-lived. Recently, two PD-1 immune checkpoint inhibitors, cemiplimab and pembrolizumab, have been approved for the treatment of advanced CSCC; specifically the former can be administered in patients with locally advanced and metastatic tumours, while the latter in case of recurrent metastatic CSCC. The introduction of immune checkpoint inhibitors represents a breakthrough in the treatment of CSCC, since numerous clinical trials showed that these agents may provide remarkable clinical benefit with an acceptable safety profile, in a high-need population who had no standard of care. In addition, real-world studies are needed to validate the results observed in clinical trials and numerous clinical trials in the neoadjuvant or adjuvant setting are ongoing. Finally, further studies should investigate predictive biomarkers useful to better select patients to maximize the treatment efficacy.

Abstract
Background: Real-life data often highlight the side effects of certain drugs not previously reported in randomized controlled trials (RCTs).Objective: To describe cutaneous inflammatory eruptions in psoriatic patients treated with an anti IL-17A agent (secukinumab or ixekizumab).Methods: Retrospective analysis of a cohort of patients with chronic plaque psoriasis who started an anti IL-17A agent between September 2016-February 2019 and who developed cutaneous inflammatory eruptions during treatment. A systematic review of similar events reported in the literature was performed.Results: Data of 468 patients were reviewed and 27 cutaneous inflammatory eruptions of 27 (5.8%) patients were collected. The eruptions appeared after a mean of 16.9 ± 17.0 weeks of therapy showing a classical acute eczema in 11 patients (40.7%), an atopic dermatitis-like rash in 11 patients (40.7%) and a psoriasiform eruption in 5 patients (18.5%). Histopathology of 12/27 cases showed epidermal spongiosis in all these variants.Conclusion: We described the clinic-pathologic features of some eczematous eruptions occurring in psoriatic patients, 3-4 months after treatment initiation with an anti IL-17A agent. Further investigations are needed to explain this phenomenon, that might be defined a paradoxical adverse event, based upon the role of IL17 in eczema pathogenesis.

Abstract
Cutaneous squamous cell carcinoma (cSCC) represents 20% of all skin cancers. Although primary cSCCs can be successfully treated with surgery, a subset of highly aggressive lesions may progress to advanced disease, representing a public healthcare problem with significant cancer-related morbidity and mortality. A complex network of genes (TP53, CDKN2A, NOTCH1 and NOTCH2, EGFR and TERT) and molecular pathways (RAS/RAF/MEK/ERK and PI3K/AKT/mTOR) have been shown to play an important role in the pathogenesis of cSCC. The epigenetic regulation of TP53 and CDKN2A is an attractive therapeutic target for the treatment of cSCC, as well as NOTCH-activating agents capable to restore its tumour-suppressor function. EGFR inhibitors including both monoclonal antibodies (cetuximab and panitumumab) and tyrosine kinase inhibitors (erlotinib, gefitinib and dasatinib) have been used in clinical trials for the treatment of advanced cSCC, achieving only partial clinical benefit. Recently, an immune-modulatory drug (cemiplimab) has been introduced for the treatment of advanced cSCC with good clinical results and a favourable safety profile, while other PD1/PD-L1 inhibitors, either as monotherapy or in combination with targeted therapies, are currently under investigation. This review focuses on molecular findings involved in the pathogenesis of cSCC and their implications for the future development of new treatment strategies. In addition, current and ongoing treatments on targeted therapies and/or immunotherapy are illustrated.

Abstract
BACKGROUND Sclerosing nevus with pseudomelanomatous features (SNPFs) is a clinical and pathologic entity that mimics melanoma both clinically and histologically. The lesion is a melanocytic nevus, histologically characterized by fibrosis and a pseudomelanomatous proliferation. It is typically seen in young to middle-aged individuals, mainly on the back, where microtrauma or inflammatory changes are more frequent. Dermoscopic description of SNPF has been reported so far in one case series. OBJECTIVE The aim of our study was to describe the dermoscopic and confocal features of SNPF. METHODS Histopathologically confirmed cases of SNPF were retrospectively collected from three referral centres in Italy. Only lesions with available clinical, dermoscopic and histopathological data were included; confocal images were also retrieved, when available. Lesions were evaluated for the presence of 12 dermoscopic and five confocal criteria previously described. RESULTS The study population included 93 lesions in as many patients (71 men and 22 women; median age: 38 years). Dermoscopically, we found a predominance of dark colours, in particular brown and blue, which were found in all lesions and the vast majority of the lesions (86/93; 92.5%) displayed at least one structureless area. By the combination of colours and structures, we observed that the majority of the lesions (67/92; 72%) were characterized by more than one structure and more than one colour. Confocal evaluation was performed on a subset of 24/93 lesions showing a regular architecture pattern (19/24 cases, 79%), with a predominance of the ringed pattern. The presence of focal cytologic atypia at the dermal-epidermal junction was present in 12/24 cases (50%) with a prevalent dendritic-shaped cell proliferation. CONCLUSIONS The current study demonstrated that SNPF was frequently characterized, on dermoscopic examination, by more than one structure and more than one colour and on confocal microscopy by a regular ringed pattern with focal dendritic atypical cells.

Abstract
Rheumatological systemic autoimmune diseases, such as connective tissue diseases, rheumatoid arthritis or spondyloarthritis, are characterized by the presence of joint involvement associated with extra-articular manifestations. Among them, cutaneous diseases are often the most relevant and representative clinical manifestation, as in psoriatic arthritis, scleroderma or systemic lupus erythematosus. In this context, it is useful for rheumatologists to understand better skin diseases and their histopathological features. Evaluation of skin biopsy specimens can be helpful not only to confirm the diagnosis in both classic and clinically atypical variants, but also to improve further our knowledge of the pathogenetic mechanisms and the close link between skin and articular diseases. In this review, we discuss the clinical features, diagnostic evaluation and the histopathological features of skin manifestation of the most relevant rheumatological autoimmune diseases.

Abstract
A non-commercial teledermatology network based on store-and-forward operation was established in April 2002. The aim was to create an easy-to-use platform for teleconsultation services, where physicians could seek diagnostic advice in dermatology from a pool of expert consultants and where they could present and discuss challenging dermatology cases with special emphasis on diagnosis and therapy. An online moderated discussion forum was added in October 2003. During the first two years, 348 health-care professionals from 45 countries registered to use the Website. A total of 783 requests for consultations were answered; 285 requests concerned pigmented skin lesions, 440 requests were from the whole range of clinical dermatology and 58 requests were about non-melanoma skin cancer. Of a total of 133 requests analysed, 80 (60%) were answered within one day, 47 (35%) within one week, five (4%) within two weeks and one (1%) consultation was answered in more than two weeks. Our experience with a discretionary, non-commercial, multilingual Website for open-access teleconsulting in dermatology appears to be successful. The Website represents an example of user-generated content, together with active interaction between users, who can present and discuss cases with remote colleagues.

Abstract
BACKGROUND The parallel ridge pattern (PRP) is considered the dermoscopic hallmark of acral melanoma (AM). However, it was recently shown that approximately one-third of AMs do not display a PRP dermoscopically, rendering their detection more troublesome. OBJECTIVES To investigate the diagnostic accuracy of dermoscopic criteria for the diagnosis of AM. METHODS Dermoscopic images of consecutive cases of histopathologically diagnosed AMs and acral naevi with histopathological diagnosis or with at least 1 year of follow-up were evaluated by three independent investigators for the presence of predefined criteria. Crude and adjusted odds ratios and their corresponding 95% confidence intervals were calculated by univariate and multivariate logistic regression, respectively. Receiver operating characteristic curves were used to choose among competing classification schemes. RESULTS In total 603 lesions (472 naevi and 131 AMs) were included in the study. A scoring system (named BRAAFF) composed of six variables was associated with optimal area under the curve and sensitivity for the diagnosis of AM. This method includes four positive (irregular blotches, ridge pattern, asymmetry of structures and asymmetry of colours) and two negative predictors (furrow pattern and fibrillar pattern). CONCLUSIONS The BRAAFF checklist significantly improves the diagnostic accuracy of dermoscopy for the diagnosis of AM.

Abstract
Basal cell carcinoma (BCC) is a slow-growing, locally invasive malignant epidermal skin neoplasm that represents the most common malignancy in Caucasians. The clinical presentation of BCC can be extremely variable: nodular, ulcerative, superficial, morpheiform, pigmented, and fibroepithelioma of Pinkus are the main clinical variants described. Clinical factors influencing negatively prognosis of BCC are: anatomic location, recurrence and/or persistance at site after treatment, and tumor size. A precise correlations between clinical and histopathological variants is not always possible, especially in biopsy samples. From a histopathological point of view various subtypes has been described: nodular, superficial, infiltrating, morpheiform, micronodular, fibroepithelial BCC and basosquamous carcinoma. A classification system based by growth pattern allows the identification of high-risk subtypes with potential tumor recurrence and aggressive biologic behavior such as infiltrating, morpheiform, micronodular and basosquamous subtypes. Further histopathological aspects determining high risk clinical morbidity are the level of invasion, perineural and lymphovascular invasion, involved surgical margins. The awareness of these clinicopathological features is helpful to better select the appropriate treatment management.

Abstract
Photodynamic therapy (PDT) with methyl aminolevulinate (MAL) is approved in Europe for the treatment of actinic keratosis and Bowen's disease, both intraepithelial forms of squamous cell carcinoma (SCC). A therapeutic effect of MAL-PDT has been recently suggested for superficial, microinvasive and well-differentiated cutaneous SCC. We describe the successful use of MAL-PDT in a recently observed patient with microinvasive SCC of the lower lip and review published data on the use of PDT with MAL or d-aminolevulinic acid (ALA) in cutaneous microinvasive SCC. A patient with a biopsy-proven recurrent microinvasive SCC of the lower lip was treated with 2 cycles of MAL-PDT. Complete clinical, dermoscopic and histopathological clearance was obtained after 2 cycles of MAL-PDT with an excellent cosmetic result and a sustained remission after 24-month follow-up. A review of the few studies reporting on the use of MAL-PDT or ALA-PDT for cutaneous microinvasive SCCs was carried out. MAL-PDT might represent a non-invasive treatment option for microinvasive SCC of the lower lip if patients are not eligible for surgery. Post-treatment histopathological confirmation and a long-term follow-up are strictly recommended.

Abstract
BACKGROUND Correctly diagnosing basal cell carcinoma (BCC) clinical type is crucial for the therapeutic management. A systematic description of the variability of all reported BCC dermoscopic features according to clinical type and anatomic location is lacking. OBJECTIVES To describe the dermoscopic variability of BCC according to clinical type and anatomic location and to test the hypothesis of a clinical/dermoscopic continuum across superficial BCCs (sBCCs) with increasing palpability. METHODS Clinical/dermoscopic images of nodular BCCs (nBCCs) and sBCCs with different degrees of palpability were retrospectively evaluated for the presence of dermoscopic criteria including degree of pigmentation, BCC-associated patterns, diverse vascular patterns, melanocytic patterns and polarized light patterns. RESULTS We examined 501 histopathologically proven BCCs (66.9% sBCCs; 33.1% nBCCs), mainly located on trunk (46.7%; mostly sBCCs) and face (30.5%; mostly nBCCs). Short fine telangiectasias, leaf-like areas, spoke-wheel areas, small erosions and concentric structures were significantly associated with sBCC, whereas arborizing telangiectasias, blue-white veil-like structures, white shiny areas and rainbow pattern with nBCCs. Short fine telangiectasia, spoke-wheel areas and small erosions were independently associated with trunk location, whereas arborizing telangiectasias with facial location. Scalp BCCs had significantly more pigmentation and melanocytic criteria than BCCs located elsewhere. Multiple clinical/dermoscopic parameters displayed a significant linear trend across increasingly palpable sBCCs. CONCLUSIONS Particular dermoscopic criteria are independently associated with clinical type and anatomic location of BCC. Heavily pigmented, scalp BCCs are the most challenging to diagnose. A clinical/dermoscopic continuum across increasingly palpable sBCCs was detected and could be potentially important for the non-surgical management of the disease.

Abstract
BACKGROUND Cerebral cavernous malformations (CCM) comprise enlarged capillary cavities in the central nervous system, with possible retinal or cutaneous vascular malformations. This condition is associated with CCM1, CCM2, and CCM3 gene mutations. OBJECTIVE Cutaneous clinical, histological and cerebral MRI findings, including CCM1, CCM2, and CCM3 gene sequencing, of two unrelated, neurological symptom-free patients who consulted for late-onset of deep multiple cutaneous angiomatoid lesions, are described. RESULTS The diagnosis of multiple cutaneous angiomatosis was confirmed and related to CCM as detected by MRI in both cases. Analysis of our patients showed normal nucleotide sequences of the genes proposed. CONCLUSIONS A progressive late-onset of multiple, deep cutaneous venous malformations may indicate the need to investigate a potential coexistence of CCM by MRI. Early diagnosis and prompt treatment is required in these patients. The absence of CCM1, CCM2, and CCM3 mutations might indicate that different genes could be involved in the pathogenesis of these late-onset patients. Careful questioning about family history of CCM is important; our first patient's daughter had a history of cerebral cavernoma.

Abstract
BACKGROUND Telemedicine is the practice of healthcare using interactive processes of communication to facilitate healthcare delivery, including diagnosis, consultation and treatment, as well as education and transfer of medical data. The aim of teledermatology, just as telemedicine, is to promote best practice procedures and to improve the consistency and competence of health care. AIM To investigate the diagnostic additive value of second opinion teleconsulting in patients with challenging dermatoses, among dermatologists working in two different dermatology departments. SETTING Thirty-three cases of patients with challenging inflammatory and neoplastic skin diseases at the University of L'Aquila Department of Dermatology were sent for teleconsultation to the Department of Dermatology, Medical University of Graz, Austria. METHODS All cases were selected in the outpatient service in L'Aquila. After face-to-face consultation with a local colleague had been completed, images were sent using a store-and-forward (SAF)-based system (http://www.telederm.org) to Graz. Histopathological examination together with follow-up of the patient represents the diagnostic gold standard for this study. RESULTS Telediagnosis was correct in 26 of 33 (78.8%) cases. Sixteen of 33 cases (48.5%) had already been diagnosed face-to-face by at least one of the two dermatologists in L'Aquila. In 10 of 33 cases (30.3%), the correct diagnosis was made in teleconsultation only. CONCLUSIONS Second opinion teleconsulting may represent an additive value in the diagnosis of numerous challenging inflammatory and neoplastic skin diseases. It may be particularly useful as a best practice model for smaller departments in order to discuss and/or to confirm diagnoses and also for the management of patients with unusual difficult dermatoses.

Abstract
BACKGROUND The accuracy of clinical diagnosis of nonpigmented, facial actinic keratosis (AK) is often suboptimal, even for experienced clinicians. OBJECTIVES To investigate the dermoscopic features of nonpigmented AK located on the head/neck that may assist the clinical diagnosis. METHODS Forty-one nonpigmented AKs on facial sites were examined by dermoscopy for any consistent underlying features. Lesions were gathered from skin cancer centres in Australia, Austria, Italy and the U.S.A. All cases were diagnosed histopathologically. RESULTS Four essential dermoscopic features were observed in facial AK: (i) erythema, revealing a marked pink-to-red 'pseudonetwork' surrounding the hair follicles (95%); (ii) white-to-yellow surface scale (85%); (iii) fine, linear-wavy vessels surrounding the hair follicles (81%); and (vi) hair follicle openings filled with yellowish keratotic plugs (66%) and/or surrounded by a white halo (100%). These features combined, in 95% of cases, to produce a peculiar 'strawberry' appearance. CONCLUSIONS A dermoscopic model of 'strawberry' pattern is presented, which may prove helpful in the in vivo diagnosis of nonpigmented, facial AK. A limitation of this study is the lack of testing of the specificity of the described dermoscopic criteria in differentiating nonpigmented AKs from other nonpigmented skin lesions at this site.

Abstract
Melanoma may mimic clinically a number of benign skin tumours by exhibiting overlapping features that do not allow accurate differentiation. Dermoscopy is a noninvasive diagnostic tool allowing the evaluation of specific subsurface morphological structures that are useful in most cases to distinguish melanoma from other melanocytic and nonmelanocytic skin tumours. In order to minimize the risk of missing melanoma, the diagnosis should be based on a good correspondence between the clinical and the dermoscopic findings. The case presented here refers to a melanoma clinically simulating dermatofibroma that was biopsied because dermoscopic examination revealed unusual features that did not confirm the clinical diagnosis.

Abstract
A metastatic cancer develops by accumulation of mutations in genes that control growth, survival and spreading. The latter genes have not yet been identified. In lymph node metastases of head and neck squamous cell carcinomas (HNSCC), we found mutations in the MET oncogene, which encodes the tyrosine kinase receptor for Scatter Factor, a cytokine that stimulates epithelial cell motility and invasiveness during embryogenesis and tissue remodeling. We identified two somatic mutations: the Y1230C, known as a MET germline mutation which predisposes to hereditary renal cell carcinoma, and the Y1235D that is novel and changes a critical tyrosine, known to regulate MET kinase activity. The mutated MET receptors are constitutively active and confer an invasive phenotype to transfected cells. Interestingly, cells carrying the MET mutations are selected during metastatic spread: transcripts of the mutant alleles are highly represented in metastases, but barely detectable in primary tumors. These data indicate that cells expressing mutant MET undergo clonal expansion during HNSCC progression and suggest that MET might be one of the long sought oncogenes controlling progression of primary cancers to metastasis.
