Abstract
BACKGROUND Cutaneous melanoma in childhood is rare; therefore, its prognostic factors and biologic behavior and the effectiveness of adjuvant diagnostic techniques in this group remain mostly unknown. METHODS The authors conducted a retrospective, observational study on the prognostic significance of clinical and pathologic findings from 137 cutaneous and mucosal melanomas in patients aged <18 years that were reviewed by the pathology department of a large cancer center during the period from 1992 to 2006. RESULTS Univariate analysis indicated that there was a significantly greater risk of metastases for patients who had previous nonmelanocytic malignancies, nodular histologic type, fusiform or spitzoid cytology, high Breslow thickness, vertical growth phase, high dermal mitotic activity, ulceration, and vascular invasion. Adjacent nevus and radial growth phase were associated with a better prognosis. Twelve patients (10.3%) died during follow-up. Decreased overall survival was related significantly to age >10 years, previous nonmelanocytic malignancy, high Breslow thickness, high Clark level, and the presence of metastases at diagnosis. All patients who died were aged ≥ 11 years, and 8 of those patients had metastases at diagnosis. In multivariate analysis, higher Breslow thickness predicted an increased risk of metastases, whereas age >10 years and the presence of metastases at diagnosis were associated with decreased survival. CONCLUSIONS Similar to adults, the detection of metastases at diagnosis in children with melanoma was 1 of the main factors that influenced overall survival. Melanomas that were detected in children aged <11 years appeared to have a less aggressive behavior than those detected in adults.

Abstract
Mitotic rate is no longer considered a staging criterion for thin melanoma in the 8th edition of the American Joint Committee on Cancer Staging Manual. The aim of this observational study was to identify prognostic factors for thin melanoma and predictors and prognostic significance of sentinel lymph node (SLN) involvement in a large multicenter cohort of patients with melanoma from nine tertiary care hospitals. A total of 4249 consecutive patients with thin melanoma diagnosed from January 1, 1998 to December 31, 2016 were included. The main outcomes were disease-free interval and melanoma-specific survival for the overall population and predictors of SLN metastasis (n = 1083). Associations between survival and SLN status and different clinical and pathologic variables (sex, age, tumor location, mitosis, ulceration, regression, lymphovascular invasion, histologic subtype, Clark level, and Breslow thickness) were analyzed by Cox proportional hazards regression and logistic regression. SLN status was the most important prognostic factor for melanoma-specific survival (hazard ratio, 13.8; 95% CI, 6.1-31.2; P < 0.001), followed by sex, ulceration, and Clark level for patients who underwent SLNB. A mitotic rate of >2 mitoses/mm2 was the only factor associated with a positive SLN biopsy (odds ratio, 2.9; 95% CI, 1.22-7; P = 0.01. SLN status is the most important prognostic factor in thin melanoma. A high mitotic rate is associated with metastatic SLN involvement. SLN biopsy should be discussed and recommended in patients with thin melanoma and a high mitotic rate.

Abstract
INTRODUCTION Hidradenitis suppurativa (HS) is a chronic disease with painful, inflamed lesions in the apocrine gland-bearing areas of the body and unsatisfactory treatment. TNFα blockers have been proposed as promising treatments, but only few randomized, short-term, small controlled trials have been conducted. The aim of this study was to evaluate long-term response of HS patients treated with infliximab (IFX). MATERIAL AND METHODS A long-term, prospective study of 10 patients with moderate-severe refractory HS treated with IFX was performed, including assessment of therapy safety, disease severity, and activity. Previous reports on IFX treatment for HS were reviewed. RESULTS Lack of response was observed in 20% and relapse in 50% of patients, after a median period of 37 weeks. The median number of doses administered was 7.5 during 49 weeks. No life-threatening adverse events were detected. Systematic review of 61 previously published cases showed lack of response was associated with previous surgery, young age at diagnosis, and long time of evolution of the disease. CONCLUSIONS Long-term IFX therapy might be an efficient, well-tolerated, safe option for patients with short-time evolution, severe HS. Relapse is common after 8 months of continuous treatment, especially in patients with more severe disease and in those treated with IFX in monotherapy.

Abstract
CONTEXT Cutaneous melanoma in childhood (CMC) is rare; therefore, its prognostic factors and biologic behavior, and the effectiveness of adjuvant techniques for CMC remain mostly unknown. OBJECTIVE To review the most useful, evidence-based practice criteria for establishing the diagnosis of CMC, for which universally accepted criteria are lacking, in order to facilitate the interpretation and comparison of the results from different institutions, and to perform systematic reviews and meta-analysis. DATA SOURCES A comprehensive review of the most relevant previous single-institution series reported in the literature since 1990, including our cumulative experience of 137 cases of primary cutaneous and mucosal melanoma in patients younger than 18 years. Special characteristics of melanoma in children are discussed, regarding clinical settings and risk factors, helpful histologic features, and immunohistochemical patterns for diagnosis and prognosis. CONCLUSIONS Careful analysis of histologic features as well as the additional information provided by immunohistochemistry should allow for a correct diagnosis in most cases of melanoma in children. Although it seems that pediatric patients with melanoma have higher survival probability than adults, still a number of children will develop metastasis and die of their disease, particularly when melanoma is diagnosed after puberty. Until further studies more accurately determine the prognosis, a prudent approach to CMC diagnosis and therapy seems to follow the same principles as those established for adult melanoma.

Abstract
Kikuchi’s disease (KD) is a self-limiting histiocytic necrotizing lymphadenitis (HNL). Cutaneous manifestations are frequent and usually show histopathological findings similar to those observed in the involved lymph nodes. HNL with superposed histological features to KD has been described in patients with lupus erythematosus (LE), and a group of healthy patients previously reported as having HNL may evolve into LE after several months. Up to date, features to predict which HNL patients will have a self-limiting disease and which could develop LE have been not identified. In order to clarify the characteristics of skin lesions associated with KD, we report a case of HNL with evolution into systemic lupus erythematosus (SLE) and a review of previous reports of KD with cutaneous manifestations. A 17-year-old woman presented with a 4-month history of fever and generalised lymphadenopathy. A diagnosis of HNL was established based on a lymph node biopsy. One month later, she developed an erythematoedematous rash on her upper body, with histopathological findings of interface dermatitis. After 8 months, anti-nuclear antibodies (ANA) at titre of 1/320, anti-DNA-ds antibodies and marked decrease of complement levels were detected. During the following 2 years, she developed diagnostic criteria for SLE, with arthralgias, pleuritis, aseptic meningitis, haemolytic anaemia and lupus nephritis. To our knowledge, 27 cases of nodal and cutaneous KD have been reported, 9 of which later developed LE. In all these patients, the skin biopsy revealed interface dermatitis. Skin biopsy revealed a pattern of interface dermatitis in all reviewed KD cases, which evolved into LE. Even this histopathological finding was not previously considered significant; it might be a marker of evolution into LE.

Abstract
Pustular dermatosis of the dorsal hands is a peculiar variant of Sweet's syndrome described by Strutton et al. Nevertheless, not all authors accept this entity. We present a retrospective study of eight cases of neutrophilic vasculitis of the hands. Three patients presented with lesions only on the dorsal hands, three with lesions on the palmar surface and two with lesions on the dorsal and palmar surfaces of the hands. The patients with lesions on the dorsal surface presented a pustular aspect, and the histopathological examination revealed a high degree of vascular damage with presence of vasculitis and, in one case, with fibrinoid necrosis. Therefore, the term pustular vasculitis of the dorsal hands introduced by Strutton et al. should probably be conserved. Our cases may have demonstrated a peculiar clinicopathological disease with its own entity.

Abstract
Objective: To report a case of lichen planopilaris in a patient treated with infliximab for longstanding refractory psoriasis. Case Summary: A 37-year-old man with recalcitrant plaque psoriasis was being treated with infliximab at a dosage of 5 mg/kg every 8 weeks, with good response. However, 11 months later the patient developed follicular keratotic papulo-pustules, perifollicular erythema, and scaling, with progressive hair toss of the frontal and parietal regions of the scalp and eyebrows. A skin biopsy from a representative lesion was consistent with the diagnosis of lichen planopilaris. Discussion: Anti-tumor necrosis factor (TNF) agents have been associated with numerous cutaneous adverse events. Lichenoid reactions are uncommon but are an emerging cutaneous adverse effect. At least 13 cases of these eruptions have been recently described. Although lichenoid reactions in patients treated with TNF-α inhibitors may be clinically very diverse, we have found no previously reported cases of lichen planopilaris induced by these agents. An objective causality assessment revealed that the adverse event was probable. Conclusions: Since anti-TNF agents are being used for a rapidly expanding number of rheumatic, digestive, and dermatologie diseases, it is expected that lichenoid eruptions and other skin toxicities are likely to be seen with increasing frequency in clinical practice.

Abstract
BACKGROUND During the last decades, the progressive ageing of the population has resulted in a rising skin cancer incidence. Although previous studies detected no higher morbidity for dermatological surgery in senior patients, their exclusion from optimal surgical treatment remains as a common clinical practice. OBJECTIVE The aim of this study was to determine the diseases treated with ambulatory major dermatological surgery, the surgical morbidity and the associated variables in ≥ 85 year-old patients. PATIENTS/METHODS This is an observational study on 247 successive patients older than 85 years of age who underwent dermatological surgery in a single Ambulatory Mayor Surgery unit. Studied variables were age, gender, tobacco-alcohol exposure, co-morbid medical conditions, blood-thinning medication, antibiotic prophylaxis, number of lesions, location, histopathological diagnosis, area of skin removed, surgical technique, type of flap, length of surgery, entrance order, suture thread, surgical complications and need of post-operative admission. RESULTS The most common site was head and neck (82.7%). The most frequent tumour was basal cell carcinoma (45.1%), followed by squamous cell carcinoma (38.7%) and melanoma (8.3%). Direct closure was the most frequent procedure (55.6%). Of the total number of patients, 7.9% of patients suffered complications; necrosis followed by cellulitis were the most frequent. Length of surgical procedure, area of skin removed and reconstruction with skin-graft were significantly related to higher risk of post-operative complications. CONCLUSIONS No intra or post-surgical mortality or life-threatening local complications were detected. Most post-surgical local complications appeared after wide excisions and complex reconstruction techniques that prolonged the length of the surgery.

Abstract
INTRODUCTION Hereditary hemorrhagic telangiectasia (HHT) or Rendu-Osler-Weber disease is an autosomal dominant disorder characterized by epistaxis, mucocutaneous telangiectases and visceral arteriovenous malformations. Cutaneous telangiectases are the most obvious sign of this disorder and are not a merely cosmetic problem owing to their risk for bleeding, which may constitute an authentic matter of concern to these patients. METHODS Three patients with type-II HHT disease who presented cutaneous and labial lesions were treated with an intense pulsed light (IPL) system associated with a long-pulsed Nd:YAG laser (Photoderm-Vasculight, Lumenis). Labial lesions were treated with the IPL system and cutaneous lesions were treated with the IPL system and the long-pulsed Nd:YAG laser. All treatments were accomplished on an outpatient basis, without anesthesia. RESULTS All three patients experienced a reduction in the frequency and severity of bleeding episodes and a great cosmetic improvement, with total lesion clearance. Side effects, such as purpura, hypopigmentation, hyperpigmentation or textural changes, were not observed. Recurrences were not detected after a maximum period of 24 months of follow-up. CONCLUSION The combination of an IPL system and a long-pulsed Nd:YAG laser is efficient and safe for the treatment of cutaneous and labial telangiectases in patients with HHT disease and constitutes an important tool in improving their quality of life.

Abstract
Cutaneous melanoma (CM) causes more deaths than any other skin tumor, and incidence and mortality rates have risen in recent years, especially in patients of advanced age. There are differences in the biological behavior of CM tumors in the elderly as well as differential management of the disease, evidently influenced by such factors as limited life expectancy, the high incidence of concomitant conditions in older patients, and issues of quality of life unrelated to CM itself. We review relevant current literature on the epidemiology, etiology, pathogenesis, and immunology of CM as well as research on the clinical features, prevention, and management of these tumors in the elderly.

Abstract
The aim of this study was to compare tumour burden in patients who underwent surgery for melanoma and cutaneous squamous cell carcinoma during nationwide lockdown in Spain due to COVID-19 (for the period 14 March to 13 June 2020) and during the same dates in 2019 before the COVID-19 pandemic. In addition, associations between median tumour burden (Breslow thickness for melanoma and maximum clinical diameter for cutaneous squamous cell carcinoma) and demographic, clinical, and medical factors were analysed, building a multivariate linear regression model. During the 3 months of lockdown, there was a significant decrease in skin tumours operated on (41% decrease for melanoma (n = 352 vs n = 207) and 44% decrease for cutaneous squamous cell carcinoma (n = 770 vs n = 429)) compared with the previous year. The proportion of large skin tumours operated on increased. Fear of SARS-CoV-2 infection, with respect to family member/close contact, and detection of the lesion by the patient or doctor, were related to thicker melanomas; and fear of being diagnosed with cancer, and detection of the lesion by the patient or relatives, were related to larger size cutaneous squamous cell carcinoma. In conclusion, lockdown due to COVID-19 has resulted in a reduction in treatment of skin cancer.

Abstract
The term `Acute Syndrome of Apoptotic Pan-Epidermolysis' (ASAP) designs clinical entities characterized by massive cleavage of the epidermis resulting from hyperacute epidermal basal cell apoptotic injury. It can be seen typically in classic toxic epidermal necrolysis (TEN), but occasionally occurs in non-dru1g-induced entities called `TEN-like' diseases (e.g., lupus erythematosus (LE), acute graft versus host disease and pseudoporphyria). We would like to highlight the difficulties of establishing differential diagnoses between `TEN-like' LE and drug reactions, especially when LE has not been previously diagnosed. We report a patient with fulminate pattern of epidermal cell injury resulting in a clinical presentation having combined features of drug-induced TEN and acute cutaneous LE with laboratory findings of systemic LE (SLE) and without systemic symptoms or high-risk drug ingestion. Although most cases of ASAP in the setting of LE are drug-induced TEN, there are reported cases of `TEN-like' LE with subacute progression, absence of systemic involvement and lack of drug ingestion. Such cases usually have a previous history of SLE and positive serologic markers. Although some authors observed that these lesions could be related to systemic severity of SLE, this is the first patient reported who progresses to discoid LE and we think it could be a marker of good prognosis. Lupus (2007) 16, 741—745.

Abstract
OBJECTIVES To examine the clinical characteristics of psoriasis, prevalence of comorbidities and quality of life in psoriasis patients older than 65 years and to compare them with younger adult psoriatic patients. DESIGN Prospective observational study of prevalence. SETTING AND PARTICIPANTS Patients older than 18 years with diagnosis of psoriasis attended at the Dermatology Department of the University Hospital of A Coruña (Galicia, Spain). A total of 371 patients were included (218 males and 153 females) with ages ranging from 18 to 85 years, of whom 70 were older than 65 years. MEASUREMENTS Demographic data, clinical characteristics and psoriasis treatment, history of hypertension, diabetes mellitus, smoking and alcohol consumption and quality of life impairment were registered. Body mass index, waist-hip ratio, left ventricular hypertrophy, average value of systolic and diastolic blood pressure, cholesterol, triglycerides and glucose blood levels were also measured. RESULTS Patients older than 65 years have statistically significant higher prevalence of hypertension, left ventricular hypertrophy, waist-hip ratio, diabetes mellitus and raised blood glucose levels. There was also association between clinical severity of psoriasis and smoking and alcohol intake as well as between quality of life and type of psoriasis treatment. CONCLUSIONS Psoriasis in patients older than 65 years represents a significant proportion of cases and its prevalence is expected to increase. Because these patients are more prone to suffer comorbidities and to develop adverse effects due to psoriasis treatment, attention to pharmacologic interactions and correction of cardiovascular risk factors and toxic habits should be especially taken in mind in this age group.

Abstract
Actinic cheilitis is thought to be a premalignant lesion or a superficial squamous cell carcinoma. The prevalence of actinic cheilitis in Europe is unknown. The aim of this study was to determine the prevalence of actinic cheilitis in the Galicia region (north-west Spain). Secondary objectives were the description of risk factors of actinic cheilitis. A cross-sectional multicentre study in patients ≥ 45 years of age was performed in 8 dermatology departments in Galicia region during a 1-year period. The prevalence of actinic cheilitis was 31.3%. Significant and independent risk factors of actinic cheilitis after multivariate analysis were age ≥ 60 years, Fitzpatrick skin phototype II, outdoor working for more than 25 years, and previous history of non-melanoma skin cancer. This is the first cross-sectional multicentre study of the prevalence of actinic cheilitis in Europe. Actinic cheilitis was present in almost one-third of the screened patients. Lip examination should be performed in all patients with chronic actinic damage.

Abstract
BACKGROUND Epidermal nevi are benign proliferations of epidermis. Numerous treatment modalities have been tried, but no ideal treatment is yet available. OBJECTIVE To report our experience with CO(2) laser vaporization in the treatment of verrucous epidermal nevi, and to identify which factors could have influence in long-term results. METHODS A total of 25 patients were treated with the CO(2) laser in the superpulsed mode, focalized at 2 W/cm(2). The patients were between 3 and 41 years old (mean: 17 years). A total of 44% of lesions were <20 cm(2), 40% measured between 20 and 100 cm(2) and 16% were >100 cm(2). The follow-up was 4-79 months (mean: 28 months). In 76% of patients, multiple treatment sessions were required. RESULTS Good results were achieved in 92% of patients with soft, flattened nevi and in only 33% patients with keratotic nevi. In addition, 87% of the latter had moderate results and 12.5% had poor results. CONCLUSION We conclude that the CO(2) laser in superpulsed mode is an effective and safe treatment for verrucous epidermal nevi and provides fewer recurrences than other laser therapies. We also believe that the most determining factor for the cosmetic result is thickness of the nevus.

Abstract
Selective immunoglobulin A deficiency (IgAD) is a primary immunodeficiency disease characterized by low levels (< 7 mg/dl) of serum immunoglobulin (Ig) A and normal serum levels of IgG and IgM. Patients with IgAD have increased risk for recurrent respiratory and gastrointestinal infections, autoimmune disease, asthma and allergy. A 26-year-old woman was admitted with sudden onset of painful cutaneous lesions on her lower extremities, pyrexia and arthromyalgia. Her medical history was remarkable for recurrent respiratory tract infections, self-limited episodes of acute diarrhea, atopy, splenomegaly and a 4-year history of a lung granulomatous lesion. Laboratory and imaging tests ruled out severe life-threatening infection, connective tissue disease and neoplasm. Serum protein electrophoresis showed a low IgA serum level (6.67 mg/dl), with normal serum levels of IgG and IgM, conducting to a diagnosis of selective IgAD. A skin biopsy showed necrotizing vasculitis without any sign of internal organ disease. We report a patient with IgAD and granulomatous involvement of lungs, spleen and medium-sized arteries of the skin. Although IgAD results from a failure of B-cell differentiation, we propose that deregulated immune response with production of cross-reactive antibodies and hyperstimulation of T cells and macrophages could contribute to this widespread granulomatous reaction.

Abstract
INTRODUCTION Knowledge on the efficacy and safety of adalimumab in psoriasis patients switching from etanercept is scarce, especially on the influence that causes of etanercept discontinuation may have on adalimumab response. OBJECTIVES To evaluate the response, adverse effects and factors that may influence the efficacy and safety of adalimumab in psoriasis patients who failed on etanercept therapy in a real-world setting. METHODS Data from all moderate to severe plaque psoriasis patients who switched from etanercept to adalimumab were extracted from a registry of biological therapies of our department. Primary endpoint was the percentage of patients achieving PASI 50 at weeks 12, 24, and 52. Secondary endpoints were the percentages of patients achieving PASI 75 and PASI 90, patients who maintained PASI values <5 and <3, and the safety of adalimumab. RESULTS Of 35 patients who fulfilled the study criteria, 82.9% achieved PASI 50 at week 12, 74.3% at week 24, and 74.3% at week 52 on adalimumab treatment. Eleven of 16 primary and 11 of 17 secondary nonresponders to etanercept responded to adalimumab. There were no treatment discontinuations due to side effects. CONCLUSIONS Previous etanercept failure seems not influence the success and safety of adalimumab treatment in moderate to severe plaque psoriasis.

Abstract
INTRODUCTION The constant increase in the incidence of skin cancer together with the requirement for maximum exploitation of available medical resources has meant that dermatological major surgery on an outpatient basis has greatly increased in recent years. OBJECTIVE This article reviews the practice of dermatological surgery in an outpatient setting over a 1-year period. Its purpose is to analyse the number of surgical procedures, the type of cutaneous processes treated and the kind of surgical intervention and anaesthesia used. We also assessed the percentage of cancellations, postsurgical hospital admission and postsurgical complications. Clinicopathological correlation and complete tumour removal were also evaluated. MATERIAL AND METHODS Our clinical experience of major surgery of outpatients at the dermatology department of the Hospital Juan Canalejo in A Coruña (Spain), analysing 565 patients in a non-randomized pilot study running from January to December 2003, is presented. RESULTS Six hundred and forty-four surgical procedures were performed on a total of 565 patients. The three main cutaneous processes treated were basal cell carcinoma (240), squamous cell carcinoma (117) and melanoma (77). The most frequent type of procedure was direct closure (346), followed by exeresis and flap (133) and partial- or full-thickness skin graft (29), nail apparatus surgery (56) and lip surgery (33). Twelve patients were admitted to hospital after surgery owing to the complexity of their operations or to complications arising during surgery. Five hundred and fifty-three patients were discharged after being kept under observation for a few hours. Seventeen patients (3%) suffered complications following surgery, which consisted of partial implant failure (six cases), infection of the surgical wound (six cases), intense pain (four cases) and haemorrhage (one case). There was a good clinicopathological correlation in 90.78% of non-melanoma skin cancers, of which 92.03% were completely removed. CONCLUSIONS Medium and high complexity operations for dermatological processes, traditionally performed on hospitalized patients, can be conducted on an outpatient basis. This allows hospitalization costs and waiting lists to be reduced and affords the possibility of achieving better morbidity rates and medical care than in the standard hospital setting.

Abstract
BACKGROUND Bowen's disease is a common form of intraepidermal (in situ) squamous cell carcinoma of the skin and mucous membrane. Treatment with destruction of the epidermis by any method is necessary to prevent invasive squamous cell carcinoma. OBJECTIVE To report our experience with CO2 laser vaporization in the treatment of Bowen's disease and try to identify which factors could have any influence on results. METHODS A total of 44 patients were treated with the CO2 laser in superpulsed mode, focalized at 2 W/cm2. RESULTS In 86.3% of patients, a unique treatment session was required. 'Clearance after one treatment' was achieved in 86.3% of the total series of patients and only 7.9% of these patients developed recurrence of the lesion. In 11.3% of the cases, there was 'clearance after more than one treatment' without clinical recurrences in any of these patients during the follow-up. 'No response' was achieved in 2.2% of the total series of patients. CONCLUSION We conclude that the CO2 laser in superpulsed mode is an effective, efficient, safe, functional and good cosmetics treatment for Bowen's disease and it provides the same recurrence rate as other more aggressive or more expensive modalities of treatment.
