Abstract
INTRODUCTION Vitamin D plays a fundamental role in many metabolic pathways, including those involved in cell proliferation and the immune response. Serum levels of this vitamin have been linked to melanoma risk and prognosis. This study aimed to assess the prognostic value of vitamin D serum level in melanoma. MATERIAL AND METHODS Retrospective, observational, longitudinal, and analytical study of 286 patients with a histologic diagnosis of melanoma in whom serum levels of vitamin D were measured at the time of diagnosis. We analyzed associations between serum level and epidemiologic and clinical variables and pathology findings; we also analyzed the influence of vitamin D on overall survival. An iterative loop was used to identify a vitamin D serum level to test for its an association with survival. RESULTS A vitamin D level less than 9.25ng/mL was associated with a histologic finding of ulceration. After a median follow-up period of 39.4 months, 24 patients (8.4%) had died. The cutoff of 9.25ng/mL was associated with lower overall survival according to both the Kaplan-Meier curves and multivariate Cox regression analysis. CONCLUSION Vitamin D levels less than 9.25ng/mL are associated with ulceration in melanoma and serve as an independent prognostic factor for overall survival in this disease.

Abstract
This article describes a proposed protocol for the histologic diagnosis of cutaneous melanoma developed for the National Cutaneous Melanoma Registry managed by the Spanish Academy of Dermatology and Venereology (AEDV). Following a review of the literature, 36 variables relating to primary tumors, sentinel lymph nodes, and lymph node dissection were evaluated using the modified Delphi method by a panel of 8 specialists (including 7 pathologists). Consensus was reached on the 30 variables that should be included in all pathology reports for cutaneous melanoma and submitted to the Melanoma Registry. This list can also serve as a model to guide routine reporting in pathology departments.

Abstract
BACKGROUND Cutaneous melanoma patients have an increased risk of developing other neoplasms, especially cutaneous neoplasms and other melanomas. Identifying factors associated with an increased risk might be useful in the development of melanoma guidelines. OBJECTIVES To identify risk factors related to the development of a second primary melanoma in a series of patients diagnosed with sporadic melanoma and to establish the estimated incidence rate. METHODS A longitudinal study based on prospective follow-up information of patients diagnosed with sporadic cutaneous melanoma at our centre from 2000 to 2015 was performed. Cumulative incidence was estimated based on competing risk models, and the association of characteristics with the risk of a second melanoma was performed by Cox proportional hazard models. RESULTS Out of 1447 patients included in the study, after a median follow-up of 61 months, 55 patients (3.8%) developed a second melanoma. Fair hair colour, more than 100 common melanocytic nevi and the presence of more than 50 cherry angiomas were independently associated with the development of a second melanoma. The site and the histological subtype of the first and second melanomas were not consistent. The second melanomas were thinner than the first ones. CONCLUSIONS Fair-haired and multiple-nevi patients might benefit from more intensive prevention measures. The finding of cherry angiomas as a risk factor suggests that these lesions could be markers of skin sun damage in the setting of certain degree of genetic susceptibility.

Abstract
BACKGROUND There is little evidence that smoking is associated with metastasis in patients with cutaneous melanoma. OBJECTIVE Using a propensity score matching analysis, we assessed whether smoking was associated with a higher rate of sentinel lymph node (SLN) metastasis and worse survival in these patients. METHODS Retrospective cohort study at a referral hospital for melanoma. We studied 762 patients with known smoking status from the melanoma database of the Instituto Valenciano de Oncología who underwent SLN biopsy between 1 January 2000 and 31 December 2016. The patients were matched by smoking status. The matching procedure was implemented using three logistic regression models featuring never vs. former smokers, never vs. current smokers and former vs. current smokers. The study outcomes were disease-free survival (DFS), melanoma-specific survival (MSS), overall survival (OS) and SLN status. RESULTS The following groups were formed based on the propensity matching scores: 114 pairs of smokers vs. never smokers, 113 pairs of smokers vs. former smokers and 174 pairs of never smokers vs. former smokers. Smoking status was not associated with SLN metastasis or with DFS, MSS or OS in any of the three groups. CONCLUSION Smoking does not influence SLN metastasis or survival in patients with cutaneous melanoma.

Abstract
BACKGROUND AND OBJECTIVES Locoregional lymph node ultrasound is not typically included in guidelines as part of the staging process prior to sentinel lymph node biopsy (SLNB). The objective of the present study was to make a clinical and economic analysis of lymph node ultrasound prior to SLNB. MATERIALS AND METHODS We performed a retrospective study of 384 patients with clinical stage I-II primary melanoma who underwent locorregional lymph node ultrasound (with or without ultrasound-guided biopsy) prior to SLNB between 2004 and 2015. We evaluated the reliability and cost-effectiveness of the strategy. RESULTS Use of locorregional lymph node ultrasound avoided SLNB in 23 patients (6%). Ultrasound had a sensitivity of 46% and specificity of 76% for the detection of metastatic lymph nodes that were not clinically palpable. False negatives were significantly more common in patients aged over 60 years and in tumors with a thickness of less than 2mm. The staging process using SLNB and ultrasound with ultrasound-guided biopsy produced an increase of €16.30 in the unit price. Our cost-effectiveness analysis identified the staging protocol with ultrasound and SLNB as the dominant strategy, with a lower cost-effectiveness ratio than the alternative, consisting of SLNB alone (8,095.24 vs. €28,605.00). CONCLUSIONS Ultrasound with ultrasound-guided biopsy for the diagnostic staging of melanoma prior to SLNB is a useful and cost-effective tool. This procedure does not substitute SLNB, though it does allow to avoid SLNB in a not insignificant proportion of patients.

Abstract
INTRODUCTION AND OBJECTIVES Primary cutaneous angiosarcoma is one of the most aggressive skin tumors and carries a very poor prognosis. Its initially indolent clinical presentation explains the frequently late diagnosis that, together with its typically multifocal pattern and poor delimitation, often makes surgery difficult. The low incidence of primary cutaneous angiosarcoma means that few large single-center series have been published. We review the clinical and pathologic characteristics of cutaneous angiosarcomas treated in our hospital, looking for prognostic factors and for possible diagnostic traits that could facilitate early diagnosis. MATERIAL AND METHODS This was a retrospective observational study including all patients diagnosed with cutaneous angiosarcoma in Instituto Valenciano de Oncología in Valencia, Spain between January 2000 and December 2015. We recorded 16 clinical parameters, including age, sex, type of angiosarcoma, site, size, and time since diagnosis, and 8 histopathologic parameters. RESULTS We identified 16 patients (11 women and 5 men) with cutaneous angiosarcoma. Their mean age was 67 years (median, 71 years). The most common site was the trunk (10 cases), followed by the head and neck (5 cases). The mean size of the tumor was 10cm (median, 6.5cm). Fourteen patients underwent surgical excision. Six of the 16 patients were alive at the end of the study, after a mean follow-up period of 42.5 months. CONCLUSIONS The major determinants of survival among patients with cutaneous angiosarcoma are tumor size and patient age. Other characteristics associated with a poor prognosis were infiltration of deep planes (muscle), a predominantly solid histologic pattern, and a larger number of mitoses.

Abstract
INTRODUCTION AND OBJECTIVES Adult dermatomyositis presents as a paraneoplastic syndrome in up to 25% of cases, but no clinical, histologic, or laboratory markers completely specific for paraneoplastic disease in dermatomyositis have been identified to date. Furthermore, studies on adult dermatomyositis do not usually report the frequency of cutaneous features of dermatomyositis in patients with associated cancer. Our aim was to review the characteristics of paraneoplastic dermatomyositis in patients seen at our hospital. MATERIAL AND METHODS We studied 12 cases of paraneoplastic dermatomyositis and recorded patient age and sex, associated cancer, time between onset of dermatomyositis and cancer, emergent cutaneous manifestations, muscle involvement, dysphagia, lung disease, and levels of creatine phosphokinase and circulating autoantibodies. RESULTS The mean age of the patients was 61 years and the 2 most common malignancies were ovarian cancer and bladder cancer. The mean time between the diagnosis of cancer and dermatomyositis was 7 months and in most cases, the cancer was diagnosed first. Seven patients had amyopathic dermatomyositis. The most common cutaneous signs were a violaceous photodistributed rash sparing the interscapular area and a heliotrope rash, followed by Gottron papules and cuticle involvement. Superficial cutaneous necrosis was observed in 3 cases. Myositis-specific autoantibodies were not detected in any of the 6 patients who underwent this test. CONCLUSIONS Paraneoplastic dermatomyositis is often amyopathic. There are no specific cutaneous markers for malignancy in dermatomyositis. Myositis-specific antibodies are not associated with paraneoplastic dermatomyositis.

Abstract
BACKGROUND Dermatofibrosarcoma protuberans (DFSP) is characterized by unpredictable subclinical extension, meaning that positive margins are frequently detected following conventional surgical excision. OBJECTIVE To study the presence or absence of residual tumour in DFSP with positive margins after conventional surgery and identify possible predictors of residual tumour or clear margins following a single Mohs micrographic surgery (MMS) stage. METHODS A retrospective study of patients with DFSP and positive margins following conventional excision referred for MMS was performed. We studied gender, age, tumour site, time from presentation to diagnosis, and affected margins. RESULTS We studied 58 cases, 35 (60.3%) of which had histological evidence of residual tumour. Tumours of the head and neck were significantly associated with the persistence of tumour. A single MMS stage was sufficient to achieve clearance in the majority of cases (n = 46). All tumours with lateral involvement only were resolved with a single Mohs stage. CONCLUSIONS DFSPs with positive margins after conventional surgical excision should undergo re-excision because the majority have histologic evidence of residual tumour. Re-excision with 1-cm margins beyond the scar could be an option in certain tumour sites, particularly when it is known which margins are involved.

Abstract
BACKGROUND AND OBJECTIVE Acral lentiginous melanomas -the melanomas most commonly found on the distal portions of the limbs- have usually reached more advanced stages than other types of melanoma when diagnosed. Our aim was to describe the clinical presentation of these tumors. MATERIALS AND METHODS Retrospective, descriptive, observational study of cases recorded in the database of the Instituto Valenciano de Oncología. In telephone interviews the patients answered a questionnaire on the presenting features of the lesion, on the presence of signs and symptoms included in the Glasgow 7-point checklist and the ABCDEs of melanoma, and on diagnostic delay attributable to patient or physician. RESULTS In the interviews with the 23 patients who responded to the questionnaire, we detected a diagnostic delay of more than 1 year attributable to the patient (delay in seeking care) in 30.4% of the cases. Diagnostic delay of more than 1 year attributable to the physician (failure to suspect the diagnosis) was identified in 20%. The most frequent reasons for consulting a physician about a lesion were changes in size, changes in color, bleeding, or failure to heal. In 20% of the cases the evaluating physician did not order histology for over a year. CONCLUSIONS Diagnostic delay is a significant problem in acral lentiginous melanoma and may be attributable either to patients or to physicians' failure to recognize warning signs. Melanoma prevention campaigns should place more emphasis on the possibility of melanomas appearing on the palms and, particularly, on the soles.

Abstract
Merkel cell carcinoma is a malignant skin tumor with a poor prognosis that primarily affects photoexposed areas of elderly patients. Tumor size is a very strong prognostic factor, with much better outcomes associated with small lesions, measuring less than 1cm. However, such lesions are rarely seen in the clinic in view of the rapid growth of this tumor. We report 2 cases of incipient Merkel cell carcinoma. Both cases of incipient Merkel cell carcinoma measured approximately 5mm in diameter. One tumor was confined to the epidermis and papillary dermis on the nose of a 79-year-old man and the other was located in the deep dermis, almost in the hypodermis, on the buttock of an 82-year-old woman. In both cases, the lesions had appeared weeks earlier. The first tumor seemed to originate in the dermoepidermal junction whereas the second originated almost in the hypodermis. Although the lesions were at a similar disease stage and had a similar size, their different locations within the dermis highlight once again the controversy about which cells give rise to Merkel cell carcinoma. The precursor cells could feasibly be Merkel cells in the first case but not in the second.

Abstract
BACKGROUND Patients diagnosed with primary cutaneous melanoma have a greater lifetime risk of developing further melanomas. Most of these melanomas appear to arise de novo, but a proportion of them develop in pre-existing melanocytic nevi. OBJECTIVE To determine risk factors associated with the development of a second cutaneous melanoma arising on a nevus in patients diagnosed with cutaneous melanoma. PATIENTS AND METHODS A series of 981 patients diagnosed with cutaneous melanoma was selected; 47 of them had been diagnosed with a second melanoma. These 47 patients were classified into 2 groups according to whether or not there was histological evidence that the melanoma was associated with a nevus. RESULTS Age at diagnosis less than 40 years, tumor location on the trunk, and superficial spreading subtype were independent risk factors for the appearance of a primary melanoma on a nevus. The only factor associated with the appearance of a second nevus-associated melanoma was that the first melanoma was also associated with a nevus (odds ratio, 9.51; 95% confidence interval 1.6-56.56; P=.042). CONCLUSIONS Nevus-associated melanomas develop mainly in young patients, on the trunk, and are of the superficial spreading subtype. A history of primary cutaneous melanoma arising on a nevus is associated with a 9-fold increase in the risk of developing a second nevus-associated melanoma. These findings highlight the need for careful follow-up of all melanocytic lesions in patients who have had a primary nevus-associated melanoma.

Abstract
Between 10 % and 35 % of all melanomas show histological regression. That is, there is an area within the melanoma where the tumor retreats or disappears to be progressively replaced by fibrosis with presence of melanophages and variable degrees of inflammation, and neovascularization. Such regression is generally considered an indicator of poor prognosis in melanoma, although a number of studies contradict this affirmation. In this review, we summarize the leading articles about the influence of regression on melanoma prognosis. The results of these studies are very inconsistent, and so the prognostic significance of regression is somewhat controversial. We believe that some of these differences can be explained by differing criteria for regression and so we propose clear histological criteria to define early and sustained regression.

Abstract
A 30 year-old man with acquired immunodeficiency syndrome was admitted because of abdominal pain, jaundice and fever. A severe pancreatitis without gallstones was detected. Later, dilation of biliary tract and clinical worsening appeared. Cholangiography revealed sclerosing cholangitis and papillary stenosis. Kaposi's sarcoma of the gallbladder invading the biliary tract was found. Only two reports of Kaposi's sarcoma of the biliary tract without cutaneous lesions have been published in a living patient. Pancreatitis has not been previously described as a clinical presentation of this malignancy.
