Abstract
Psoriasis has been controversially associated with risk of non-Hodgkin lymphoma (NHL) and mycosis fungoides (MF). Also patients who developed MF after systemic treatment for psoriasis have been reported, and some authors suggested that the association between MF and psoriasis is not infrequent. We performed an extensive literature review in order to examine the risk of developing MF in psoriatic patients with a systematic search of the English-language databases. An increased risk for lymphoma overall in psoriatic patients has been found only by three out of seven studies. The risk of developing MF in psoriatic patients has been investigated by different studies in different populations and with different methodologies presenting bias and limitations, and it seems reasonable that misclassification between psoriasis and MF may explain the association reported. In contrast to the large number of psoriatic patients treated with biologicals, only 27 case reports of MF after biological therapy for psoriasis have been reported, and in 10 cases, the initial psoriasis diagnoses were then revised as MF. A true association between MF and psoriasis is possible, but the real incidence and prevalence are still unknown. The reported higher risk of developing MF in psoriatic patients should be reconsidered in the light of the bias of misclassification and the low magnitude reported in previous studies. There is not enough evidence to support a causal relation among biological therapies and MF in psoriatic patients.

Abstract
BACKGROUND The differential diagnosis between regressing nevi and melanoma might be challenging; regressing areas can represent a confounding factor for the diagnosis and the histology still remain mandatory to rule out melanoma. Reflectance confocal microscopy may add valuable information by revealing features suggestive of the nature of the melanocytic proliferation. OBJECTIVE To assess the impact of confocal microscopy in the management of regressive melanocytic lesions. METHODS The dermoscopic analysis of 92 melanocytic lesions showing that more than 30% of regressions have been retrospectively considered, among them, 32 melanocytic lesions with a 7 check point list ≥3 they were assessed at the rcm and subsequently excised. For each selected lesion, dermoscopic features of regression (white scar-like areas, blue areas, blue white areas), distribution of regressing areas (central, peripheral, or both) and the percentage of regression have been examined by an expert in dermoscopy, blinded to the histological and confocal diagnosis. Subsequently, two experts in confocal microscopy revaluated, blinded from histology, RCM images. RESULTS Of the 32 lesions analyzed, 23 (71.5%) were diagnosed histologically as nevi, and 9 (28.5%) as melanomas. 26 of 32 lesions (81.5%) exhibited regression >50% of the overall. On RCM, 11 lesions have been interpreted as malignant and 21 as benign. On RCM the majority of nevi exhibited regular architecture without cytological atypia. Epidermal disarray, pagetoid infiltration, disarranged dermo-epidermal junction architecture and atypical nests were considered as suspicious for malignancy. Good concordance between confocal readers has been detected. CONCLUSION A combined dermoscopic/confocal approach can be used for the management of lesions exhibiting dermoscopic features of regression in order to provide a more conclusive pre-histological diagnosis avoiding a high number of unnecessary excisions. Limits of this study were represented by the relatively small number of lesions and the retrospective approach. Further, prospective studies on a larger number of cases, will be necessary in order to compare the efficacy of dermoscopy alone versus dermoscopy in combination with RCM for the evaluation of regression, suspected pigmented lesions.

Abstract
BACKGROUND Polymorphisms of NLR (nucleotide-binding domain and leucine rich repeat containing) family, pyrin domain containing protein 1 (NLRP1) have been found in patients with vitiligo/nonsegmental vitiligo (NSV), and increased NLRP1 expression has been detected in the leading edge of lesional skin biopsies. OBJECTIVES To evaluate the presence and intensity of NLRP1 immunostaining in lesional and perilesional skin of patients with vitiligo/NSV and to search for possible correlations between NLRP1 and interleukin (IL)-1β expression, lymphocytic infiltrates and disease activity. METHODS Of 14 consecutive vitiligo/NSV patients, eight had active disease [Vitiligo European Task Force (VETF) spreading score +1 to +5], one patient had stable disease and five patients had regressive disease (VETF spreading score -1 to -3). We performed immunostaining for NLRP1, B and T lymphocytes, IL-1β and kallikrein 7 on lesional and perilesional vitiligo skin. RESULTS NLRP1 and IL-1β immunostaining in perilesional vitiligo/NSV skin was significantly associated with progressive disease (P = 0·009 and 0·04, respectively) and performed better than the simple detection of lymphocytic infiltrates. CONCLUSIONS Our findings suggest that markers of the NLRP1 inflammasome could be a useful test for assessing disease activity in addition to the detection of inflammatory infiltrates in the progressing margins of vitiligo/NSV lesions.

Abstract
BACKGROUND Naevoid melanoma (NeM), a rare variant of melanoma, can be difficult to detect as its clinical and histopathological morphology can simulate a naevus. OBJECTIVES To describe the clinical and dermoscopic features associated with NeM. METHODS Lesions with a histopathological diagnosis of NeM were collected via an e-mail request sent to all members of the International Dermoscopy Society. All lesions were histopathologically reviewed and only lesions fulfilling a set of predefined histopathological criteria were included in the study and analysed for their clinical and dermoscopic features. RESULTS Twenty-seven of 58 cases (47%) fulfilled the predefined histopathological criteria for NeM and were included in the study. Clinically, 16 of the 27 NeMs presented as a nodular lesion (59%), eight (30%) as plaque type and three (11%) as papular. Analysis of the global dermoscopic pattern identified three types of NeM. The first were naevus-like tumours (n = 13, 48%), typified by a papillomatous surface resembling a dermal naevus. In these lesions local dermoscopic features included irregular dots/globules (46%), multiple milia-like cysts (38%) and atypical vascular structures (46%). The second type were amelanotic tumours (n = 8, 30%), typified by an atypical vascular pattern (75%). The third type consisted of tumours displaying a multicomponent pattern (n = 4, 15%), characterized by classical local melanoma-specific criteria. Two lesions (7%) were classified as mixed-pattern tumours as they did not manifest any of the aforementioned patterns. CONCLUSIONS While NeMs may be clinically difficult to differentiate from naevi, any papillomatous lesion displaying dermoscopically atypical vessels and/or irregular dots/globules should prompt consideration for the possible diagnosis of NeM.

Abstract
BACKGROUND Punch grafting is a surgical technique mainly applied in therapy-resistant, stable and circumscribed vitiligo. OBJECTIVE (i) To characterize in detail the features of the repigmented skin among punch grafts; and (ii) to correlate the ex vivo results with clinical data and punch grafting outcome. METHODS We evaluated by immunohistochemistry and image analysis the expression of a panel of specific melanocyte markers including HMB45, MITF, c-kit, MART-1 and TRP1, the proliferation marker Ki67 and the cell-cell adhesion molecule E-cadherin in tissue samples collected from nine patients after punch grafting. RESULTS Cells positive for MITF, c-kit, MART-1 and TRP1 were detected in the repigmented skin of all biopsies, whereas no reactivity was observed for HMB45. Melanocytes were identified along the entire length of the sections, and their mature state was assessed by the immuno-reactivity for the differentiation marker MART-1, the absence of cells positively stained for Ki67 and by the co-expression of c-kit and TRP1, a marker of a differentiated and pigmented state. Clinically, smaller punch grafts aimed at repigmenting lesional areas on the face gave the faster clinical results with no side-effects. Patients subjected to bigger punch grafts on the knee exhibited a longer repigmentation time and presented cobble stoning. CONCLUSION Our results suggest that the repigmentation observed in the areas between the grafts is due to the activation of the melanocytes located in the donor sites. These cells start to horizontally migrate towards the lesional skin thanks to successively the enlargement of intercellular spaces in relation to a decrease of E-cadherin reactivity and the up-modulation of pro-melanogenic mediators. Production and transfer of melanin in the surrounding keratinocytes and their persistence were assessed by the reactivity for MITF, c-kit, MART-1 and TRP1 but not for the pre-melanosome marker (HMB45).

Abstract
AIM AND METHODS We analyzed 159 stored specimens of Lichen Sclerosus (LS) collected in the period 1999-2011 from 159 patients, in order to evaluate the histological patterns, clinical outcomes and possible associations with malignancies. The histopathologic analysis revealed 145 cases (males and females) with LS alone, 7 in whom penile LS was associated with spinocellular carcinoma (SCC), and 7 in whom LS was associated with a pseudocarcinomatous-hyperplasia (PCH). Extragenital LS was found in 20% (17/85) of the males and 78% (58/74) of the females. In the cases of SCC, immunohistochemical analyses was performed. RESULTS AND CONCLUSION The results showed very low positivity to p16INK4A and Ki-67; biomolecular PCR was positive in only two cases, and in both cases the non-oncogenic genotype HPV 100 was detected. No important additional risk factors for malignancies were found (e.g., hormones, infections, other autoimmune diseases).

Abstract
Psoriasis is a chronic inflammatory skin disease, characterized by an enhanced proliferation and a deregulated differentiation of keratinocytes. hMena is an actin regulatory protein involved in the control of cell motility and adhesion. hMena results up-modulated in several human tumors with respect to normal tissues and its expression has been positively correlated to proliferation rate, tumor size and aggressiveness in response to mitogenic stimuli, such as epidermal growth factor. The hyperproliferation of keratinocytes observed in psoriasis prompted us to evaluate hMena expression on biopsies collected from involved and uninvolved skin of 12 patients with active plaque-type psoriasis with respect to healthy skin. We analyzed the expression of hMena at transcript and protein levels by quantitative RT-PCR and immunohistochemistry. We correlated the expression of hMena to Ki67 proliferation index and to keratin 10 (K10) and keratin 16 (K16) used as markers of keratinocyte differentiation and activation. We demonstrated the expression of hMena in a hyperproliferative skin condition not related to neoplastic transformation. Interestingly, we observed that hMena is not expressed in healthy skin, but it becomes detectable in non-lesional areas and it is even more expressed in lesional psoriatic skin. In addition, we found that hMena expression is correlated to the rate of keratinocyte proliferation and activation. Hence, our observations indicate hMena as a new possible player, involved in the development and/or maintenance of the hyperproliferative state of psoriatic keratinocytes.

Abstract
BACKGROUND Dermatofibroma is a common skin neoplasm that is usually easy to recognize, but in some cases its differentiation from melanoma and other tumours may be difficult. OBJECTIVE To describe the dermoscopic features of dermatofibromas, with special emphasis on the characteristics of atypical patterns, and to calculate pattern frequency according to the patients age and gender, anatomical site and histopathological subtype. METHODS Two groups of patients were consecutively seen, one with dermatofibromas that were surgically excised because of clinically and/or dermoscopically equivocal aspects or following patient request, and another with non-equivocal dermatofibromas. Each lesion was scored for previously reported global dermoscopic patterns and for additional features. RESULTS A typical pattern was observed in 92 of 130 (70.8%) lesions, whereas an atypical pattern, that we named the 'non Dermatofibroma (DF)-like' pattern, was seen in 38 of 130 (29.2%). Atypical dermatofibromas showed features reminiscent of different conditions, such as melanoma in 21(16.2%) cases, vascular tumour in six (4.6%), basal cell carcinoma in five (3.8%), collision tumour in three (2.3%) and psoriasis in three (2.3%). A significant association was found between the 'melanoma-like' pattern/'vascular tumour-like' pattern and males, whereas a trend was observed between the above-mentioned patterns and hemosiderotic/aneurysmal DFs. 'Peripheral pigment network and central white scar-like patch' pattern was found associated with females and classic histopathological variant of DF. CONCLUSION Dermatofibromas may display different morphological faces. The typical dermoscopic patterns allow a confident diagnosis, whereas a full surgical excision is always recommended in all doubtful cases.

Abstract
Despite the high frequency of intradermal facial nevi in adults, the development of lentigo maligna (LM) within a preexisting nevus is considered exceptionally rare. Herein we describe an emblematic case of nevus associated facial LM and discuss whether such "collision" is coincidental or a consequence of malignant transformation.

Abstract
BACKGROUND Lichen planopilaris (LPP) and discoid lupus erythematosus (DLE) are the most common causes of lymphocytic primary cicatricial alopecia. The management of scarring alopecia can be difficult. The combination of clinical, dermoscopy and reflectance confocal microscopy (RCM), a noninvasive, high-resolution imaging technique, examinations have already been demonstrated to be useful for choosing the correct biopsy site in patients with inflammatory skin disease and obtaining microscopic diagnostic criteria. OBJECTIVES We evaluated the usefulness in practice of RCM for the identification of criteria for LPP and DLE involving the scalp and their management during therapeutic follow-up. METHODS Seven white patients with a previously established histological diagnosis of DLE (three) and LPP (four), were included in the study. RCM criteria for primary scarring alopecia were selected: epidermal disarray, spongiosis, exocytosis of inflammatory cells in the epidermis, interface dermatitis, peri- and intra-adnexal infiltration of inflammatory cells, dilated vessels in the dermis, dermal infiltration of inflammatory cells and melanophages and dermal sclerosis. All patients were followed up using RCM during the treatment. During follow-up the RCM evolution of the epidermal, junctional and dermal inflammation were evaluated. RESULTS A series of RCM features of scalp LPP and DLE were identified that show correlation with the histopathological evaluation. During the treatment follow-up of the cases RCM was shown to be sensitive for the identification of therapeutic response. CONCLUSION In our preliminary study the effective usefulness of RCM for the diagnosis of scarring alopecia and follow-up seemed to be evident. Moreover, RCM seems to be also promising for differential diagnosis between the different entities.

Abstract
BACKGROUND Cutaneous pigmentation is regulated by a complex melanogenic network in which both keratinocytes and fibroblasts synthesize growth factors and cytokines. Solar lentigo (SL) is characterized by hyperpigmented lesions occurring on photodamaged skin areas. Despite the association of SL to ultraviolet (UV) exposure, the mechanisms underlying the development of these spots are not completely defined. OBJECTIVES To analyse the involvement of the fibroblast-derived growth factors, hepatocyte growth factor (HGF), keratinocyte growth factor (KGF) and stem cell factor (SCF) in SL hyperpigmentation; to evaluate whether the photoageing process occurring in fibroblasts could be responsible for the altered expression of these cytokines; and to investigate a new possible role of KGF in regulating pigmentation through the specific induction of melanogenic cytokines by keratinocytes. METHODS We performed immunohistochemical analysis of HGF, KGF and SCF on SL biopsies. We analysed the mRNA expression of these cytokines using an in vitro model of photoageing induced on fibroblasts. Finally, we evaluated the effects of KGF on the expression of melanogenic cytokines at the mRNA and protein levels on keratinocytes. RESULTS We found positive staining for HGF, KGF and SCF in the upper dermis of SL lesions and a significant induction of the three cytokines in photoaged fibroblasts. We also demonstrated the contribution of KGF to pigmentation, showing its ability specifically to modulate the expression of SCF in keratinocytes. CONCLUSIONS Fibroblasts may be persistently activated by UV exposure to release melanogenic growth factors; this inducible cytokine network acts both directly and indirectly through keratinocytes and may contribute to the hyperpigmentation of SL.

Abstract
BACKGROUND Discoid lupus erythematosus (DLE) can simulate other inflammatory diseases both clinically and histologically. In vivo reflectance confocal microscopy (RCM) is a noninvasive, reproducible imaging technique already reported to be useful in the evaluation of several inflammatory skin conditions such as contact dermatitis, psoriasis and Darier disease. OBJECTIVES The aims of our study were to define RCM features of DLE and to evaluate its feasibility in biopsy site selection. METHODS Discoid lesions were selected for RCM evaluation from 10 patients with an established diagnosis of DLE. Subsequently, a 4-mm punch biopsy of the same areas evaluated with RCM was rendered for histopathological examination. RESULTS A series of RCM features of DLE was identified and shown to correlate well with histopathological evaluation. Interface changes, as well as epidermal, dermal and adnexal inflammatory cell infiltration, were identified with RCM in a high percentage of the lesions. A limitation of RCM examination besides imaging depth was the inability to distinguish lymphocytes from other white blood cells. CONCLUSIONS The utility of RCM as a diagnostic tool for DLE awaits further evaluation, although it appears to be promising for biopsy site selection.

Abstract
BACKGROUND Aberrant activation of beta-catenin contributes to the onset of a variety of tumours. There are many tumours that display beta-catenin accumulation in the absence of mutations in its gene. Recently, abnormal accumulation of wild-type beta-catenin has been associated with mutational inactivation of the p53 tumour suppressor. OBJECTIVES To investigate the potential role of p53 and its homologue p63 in beta-catenin deregulation and to correlate this with disease outcome. METHODS We analysed a panel of 24 samples of mycosis fungoides (MF), the most frequent manifestation of cutaneous T-cell lymphoma (CTCL), for beta-catenin, p53 and p63 protein expression by immunohistochemistry. Based on the immunostaining results for beta-catenin protein, 11 positive cases were selected for laser microdissection, genomic DNA isolation and subsequent mutation analysis of beta-catenin exon 3 and p53 exons 4-8. RESULTS Our findings revealed overexpression of beta-catenin, p53 and p63 in 46%, 38% and 17% of cases, respectively. The number of p53-positive cases of MF was significantly higher (P < 0.05) in the beta-catenin-positive group (73%). Sequence analysis demonstrated that wild-type beta-catenin accumulation in MF is not associated with mutational inactivation of the p53 gene and, more importantly, our data provide evidence that a common polymorphic form of p53 (Arg72Pro) is significantly associated with beta-catenin overexpression (P < 0.05). No significant differences in the three genotypes were observed between the CTCL cases and the control group, demonstrating that Arg72Pro polymorphism of the p53 gene is not associated with the risk of developing cutaneous lymphomas (P > 0.05). CONCLUSIONS We found an association of beta-catenin and p53 overexpression without detection of structural alteration in the genes, suggesting that p53 mutation is not an important mechanism for beta-catenin activation in primary CTCL. Additionally, we speculate that the p53 codon 72 polymorphism may influence negative feedback control involving beta-catenin and p53.

Abstract
Erosive pustular dermatosis of the scalp (EPDS) is a rare entity characterized by pustular, erosive and crusted lesions of the scalp with progressive scarring alopecia. The aetiology is unknown, but predisposing factors have been reported such as trauma, skin grafting, prolonged exposure to UV light of a bald scalp as well as co-existence of auto-immune diseases. Laboratory data, bacteriological and mycological investigations and histopathology are generally not diagnostic. A 45-year-old Caucasian man with 1-year-old pustular, erosive and crusted lesions on his bald scalp was seen. Laboratory data, including auto-immunity, bacteriological and mycological investigations were negative. Histopathology was not diagnostic showing a diffuse polymorphous infiltrate involving the dermis. A diagnosis of EPDS was made. The patient was treated with topical and systemic antibiotics and steroids as well as oral nimesulide with no or partial response. Consequently, isotretinoin (0.75 mg/kg/day) was started obtaining complete resolution in few months. No relapse after 1 year of follow-up was seen. EPDS represents a distinct disease with a history of relapsing and unsatisfactory response to common treatments. Systemic retinoids may be considered as a potentially resolutive choice.

Abstract
The pathogenic mechanism underlying the hyperproliferation of keratinocytes in psoriasis is still not completely clarified. The production of cytokines released by activated T lymphocytes infiltrating the upper dermis probably has a crucial role. Even dermal fibroblasts can participate in the process through the secretion of growth factors, and some studies have reported an increased expression of the insulin-like growth factor 1. Few studies, however, have focused on the possible involvement of the keratinocyte growth factor (KGF/FGF-7) and the fibroblast growth factor 10 (FGF-10/KGF-2), which are secreted by fibroblasts and stimulate keratinocyte proliferation acting through a receptor specifically expressed by epithelial cells. The aim of this study was to investigate the expression of KGF and FGF-10 on the skin of patients with psoriasis by immunohistochemical analysis and to evaluate the correlation with the lymphocyte infiltrate and the epidermal proliferation. Immunostaining for KGF and FGF-10 showed that both the growth factors are upregulated in the upper dermis of psoriatic skin, and that the expression is correlated with the presence of T-cell infiltrate and with keratinocyte proliferation. Our data suggest that in psoriatic lesions activated lymphocytes can stimulate fibroblasts to produce KGF and FGF-10, which in turn contribute to sustain the hyperproliferative status of the keratinocytes.
