Risk of a Second Skin Cancer in a Cohort of Patients With Nonmelanoma Skin Cancer -Basal Cell Carcinoma or Squamous Cell Carcinoma-Treated With Mohs Micrographic Surgery: A National Prospective Cohort Study. / Riesgo de aparición de segundas neoplasias cutáneas en una cohorte de pacientes diagnosticados de carcinoma queratinocítico (carcinoma basocelular y carcinoma epidermoide) tratados con cirugía de Mohs. Estudio de cohortes prospectivo nacional.

OBJECTIVE: Patients with nonmelanoma skin cancer (NMSC)-ie, basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)-have an increased risk of developing a second skin cancer. The aim of this study was to describe the frequency, incidence per 1000 person-years, and predictors of a second skin cancer in a cohort of patients with NMSC treated with Mohs micrographic surgery (MMS). MATERIAL AND METHODS: Prospective study of a national cohort of patients with NMSC who underwent MMS at 22 Spanish hospitals between July 2013 and February 2020; case data were recorded in the REGESMOHS registry. The study variables included demographic characteristics, frequency and incidence per 1000 person-years of second skin cancers diagnosed during the study period, and risk factors identified using mixed-effects logistic regression. RESULTS: We analyzed data for 4768 patients who underwent MMS; 4397 (92%) had BCC and 371 (8%) had SCC. Mean follow-up was 2.4 years. Overall, 1201 patients (25%) developed a second skin cancer during follow-up; 1013 of the tumors were BCCs (21%), 154 were SCCs (3%), and 20 were melanomas (0.4%). The incidence was 107 per 1000 person-years (95% CI, 101-113) for any cancer, 90 per 1000 person-years (95% CI, 85-96) for BCC, 14 (95% CI, 12-16) per 1000 person-years for SCC, and 2 (95% CI, 1-3) per 1000 person-years for melanoma. More men than women developed a subsequent skin cancer (738 [61%] vs 463 [39%]). The main risk factors were a history of multiple tumors before diagnosis (relative risk [RR], 4.6; 95% CI, 2.9-7.1), immunosuppression (RR, 2.1; 95% CI, 1.4-3.1), and male sex (RR, 1.6; 95% CI, 1.4-1.9). CONCLUSION: Patients have an increased risk of developing a second tumor after MMS treatment of NMSC. Risk factors are a history of multiple tumors at diagnosis, immunosuppression, and male sex.

Mohs micrographic surgery in the elderly: comparison of tumours, surgery and first-year follow-up in patients younger and older than 80 years old in REGESMOHS.

BACKGROUND: The elderly population is increasing and more patients in this group undergo Mohs micrographic surgery (MMS). The few publications investigating MMS in elderly people conclude that it is a safe procedure; however, these are single-centre studies without a comparison group. OBJECTIVE: To compare the characteristics of patients, tumours, MMS and 1-year follow-up in patients younger than 80 years, with patients older than 80 years at the time of surgery. METHODS: Data was analysed from REGESMOHS, a prospective cohort study of patients treated with MMS. The participating centres were 19 Spanish hospitals where at least one MMS is performed per week. Data on characteristics of the patient, tumour and surgery were recorded. Follow-up data were collected from two visits; the first within 1 month postsurgery and the second within the first year. RESULTS: From July 2013 to October 2016, 2575 patients that underwent MMS were included in the registry. Of them, 1942 (75.4%) were aged <80 years and 633 (24.6%) were ≥80 years old. In the elderly, the tumour size was significantly higher with a higher proportion of squamous cell carcinoma. Regarding surgery, elderly more commonly had tumours with deeper invasion and required a higher number of Mohs surgery stages, leaving larger defects and requiring more time in the operating room. Despite this, the incidence of postoperative complications was the same in both groups (7%) and there were no significant differences in proportion of relapses in the first-year follow-up. CONCLUSION: The risk of short-term complications and relapses were similar in elderly and younger groups. MMS is a safe procedure in the elderly.

Characterization of Surgical Procedures in the Spanish Mohs Surgery Registry (REGESMOHS) for 2013-2015. / Descripción de las intervenciones quirúrgicas recogidas en el registro español de cirugía de Mohs (REGESMOHS) (2013-2015).

INTRODUCTION: The Spanish Mohs Surgery Registry is used to collect data on the use and outcomes of Mohs micrographic surgery (MMS) in Spain. The aim of this study was to describe perioperative and intraoperative data recorded for MMS procedures performed between July 2013 (when the registry started) and January 2016. MATERIAL AND METHODS: Prospective cohort study of data from 18 hospitals. The data collected included type of anesthesia, surgical technique, hospital admission, number of Mohs stages, management of preoperative risk factors, additional treatments, previous treatments, type of tumor, operating time, and complications. RESULTS: Data were available for 1796 operations. The most common tumor treated by MMS was basal cell carcinoma (85.96%), followed by squamous cell carcinoma (6.18%), lentigo maligna (2.81%), and dermatofibrosarcoma protuberans (1.97%). Primary tumors accounted for 66.9% of all tumors operated on; 19.2% of tumors were recurrent and 13.9% were persistent. The most common previous treatment was surgical. MMS was mostly performed under local anesthesia (86.7% of cases) and as an outpatient procedure (71.8%). The frozen section technique was used in 89.5% of cases. One stage was needed to achieve tumor-free margins in 56.45% of patients; 2 stages were required in 32.1% of patients, 3 in 7.1%%, 4 in 2.7%, and 5 or more in 1.8%. The defect was reconstructed by the dermatologist in 98% of patients and the most common technique was flap closure (47.2%). Intraoperative complications were recorded for just 1.62% of patients and the median (interquartile range) duration of surgery was 75 (60-100) minutes. CONCLUSION: The characteristics of the patients and tumors treated by MMS are similar to those reported for similar studies in other geographic areas. Lentigo maligna and dermatofibrosarcoma protuberans accounted for a higher proportion of cases in our series, and repair of the surgical defect by a dermatologist was also more common. Operating times in MMS are not much longer than those reported for other procedures and the rate of intraoperative complications is very low.

Description of Patients Undergoing Mohs Surgery in Spain: Initial Report on Data From the Spanish Registry of Mohs Surgery (REGESMOHS).

INTRODUCTION: The Spanish registry of Mohs micrographic surgery started collecting data in July 2013. The aim of the registry is to report on the use of this technique in Spain and the outcomes achieved. In the present article, we describe the characteristics of patients and the tumors treated. MATERIAL AND METHODS: This is a prospective cohort study of patients treated with Mohs micrographic surgery. The participating centers are hospitals where at least one intervention of this type is performed each week. All patients considered for Mohs micrographic surgery in participating centers are included in the registry except those who have been declared legally incompetent. RESULTS: Between July 2013 and October 2014, data from 655 patients were included in the registry. The most common tumor involved was basal cell carcinoma, and the most common histological subtype was infiltrative basal cell carcinoma. Most of the tumors treated were located on the face or scalp, and the most common site was the nose. Almost 40% of the tumors treated were recurrent or persistent, and preoperative tumor size was similar to that reported in other European studies and in Australia. In total, 45.5% of patients had received previous surgical treatment. CONCLUSION: The findings are similar to those reported in other studies, and the data collected are useful for assessing whether the results of studies carried out elsewhere are applicable in Spain.

Strategic Plan for the Spanish Academy of Dermatology and Venerology (AEDV): FuturAEDV 2013-2017.

BACKGROUND: The Spanish Academy of Dermatology and Venereology (AEDV) has decided that a Strategic Plan is needed to help the association adapt to new circumstances and anticipate future developments. OBJECTIVES: 1) To position the AEDV as a medical association that can exert an influence in everything related to dermatology. 2) To contribute to the development of the specialty, strengthening the prestige and reputation of dermatology and dermatologists. 3) To establish a model for operating and strategic thinking that can be handed on to successive Boards of Directors and will enable the Academy to identify future challenges. METHODS: The approach used to develop the Strategic Plan was as follows: analysis of trends in the health care system; assessment of the current situation of AEDV and of dermatology in general through an internal analysis based on surveys and interviews with academics; analysis of strengths, weaknesses, opportunities, and threats; preparation of a mission statement; and identification, development, and implementation of a strategy map prioritizing strategic lines of action. RESULTS: The strategy map set out 16 general goals grouped into 4 main topics (achieving the vision, internal and external customers, internal processes, and innovation) and detailed in an action plan with 19 initiatives, each with specific actions. The plan will be monitored by the Strategic Plan Monitoring Committee, which is made up of the members of the Standing Committee and the chairs of the 9 Technical Committees responsible for implementing the initiatives. COMMENT: The Functional Plan should guide the management of AEDV until 2017, and its implementation will enable the association to contribute to the development and prestige of the specialty and position itself as a reference in terms of its functional model.

[My clinical experience with efalizumab in the Hospital of Conxo]. / Mi experiencia clínica con efalizumab en el Hospital de Conxo.

Psoriasis in plaques is a chronic disease that requires systemic treatment in its moderate and severe forms. Because the need for treatment is generally prolonged, many medications indicated for its treatment cannot be used continuously and have to be replaced by other different drugs, but also with a limited use, both due to their possible side effects, their teratogenicity, the time of use and accumulated dose, among other reasons. The biological drugs have been designed for middle and long term control of the disease. Efalizumab is a drug that has been shown to be effective and safe in patients who have moderate-to-severe psoriasis. We present our results in a group of 50 patients, our special cases, the form in which we have treated the side effects due to Efalizumab and those due to the disease.

Systemic Treatment of Moderate to Severe Psoriasis in Pediatric Patients in Galicia, Spain: A Descriptive Study. / Tratamiento sistémico de la psoriasis moderada-grave en edad pediátrica en Galicia: estudio descriptivo.

BACKGROUND AND OBJECTIVE: Studies on the use of systemic therapy for psoriasis in pediatric patients are scarce. The main aim of this study was to describe the systemic treatments used for moderate to severe psoriasis in pediatric clinical settings. The second aim was to describe the effectiveness and safety of these treatments. MATERIAL AND METHODS: Descriptive, cross-sectional, multicenter study of patients under 18 years of age with moderate to severe psoriasis who were being treated or had been treated with a systemic drug (conventional or biologic) or phototherapy. We recorded demographic and clinical information, treatments received, tolerance, adverse effects, and response to treatment. RESULTS: Data were collected for 40 patients (60% female; mean age, 13 years) who had received 63 treatments in total. The most common first treatment (n=40) was phototherapy (administered to 68% of patients), followed by acitretin (15%). The most common treatments overall (n=63) were phototherapy (57%) and methotrexate (16%). At week 12 (evaluation of systemic treatment and phototherapy), 66% of the patients were classified as good responders and 22% as partial responders. The respective rates for week 24 (evaluation of systemic treatment only) were 36% and 32%. The treatments were well tolerated (97%) and adverse effects were reported in just 11% of cases. There were no treatment discontinuations because of adverse effects. CONCLUSIONS: Phototherapy, followed by methotrexate, was the most common treatment for moderate to severe psoriasis in this series of patients under 18 years. The treatments showed a favorable safety profile and were associated with a good response rate of 66% at week 12 (systemic treatment and phototherapy) and 36% at week 24 (systemic treatment only).

Description of patients excluded for Mohs surgery after pre-surgical evaluation: data from the Regesmohs Spanish registry. / Descripción de pacientes no aptos para ser sometidos a cirugía de Mohs tras valoración prequirúrgica: datos del registro español Regesmohs.

BACKGROUND: Regesmohs registry is a nationwide registry including patients evaluated for Mohs surgery in 17 Spanish centres since July 2013. Given that Mohs surgery is the therapy with best results for high risk basal cell carcinoma (BCC) and other skin tumours, we wanted to describe the reasons that lead to some patients being excluded from this therapy and the alternative treatments that they received. These data may be useful to avoid excluding patients for Mohs surgery use, to estimate the healthcare demand of these patients and the demand for Hedgehog inhibitors therapy in this group. OBJECTIVE: To describe patients excluded for Mohs surgery after pre-surgical assessment, and the treatments that they received. METHODS: Regesmohs includes all consecutive patients assessed for Mohs surgery in the participating centres, collecting data on patient characteristics, intervention, and short and long-term results. Patients excluded for Mohs surgery after pre-surgical evaluation were described. RESULTS: 3011 patients were included in Regesmohs from July 2013 to October 2016. In 85, Mohs surgery was not performed as they were considered inadequate candidates. 67 had BCC. Reasons for exclusion were: medical contraindication (27.1%, n=23) low-risk tumour in (18.8%, n=16) and giant tumour and bone invasion (15.3%, n=13). Only 1 patient (1.2%) showed lymph node involvement and no patients had visceral metastases. Of the 85 excluded patients, 29 (34.1%) were treated with conventional surgery, 24 (28.3%) with radiotherapy, 4 (4.7%) with inhibitors of the Hedgehog pathway (only indicated for BCC), and 2 (2.4%) received palliative care. We had no follow-up data on 14 patients (16.5%). CONCLUSION: Medical comorbidities were the most common reason for withholding Mohs surgery. Withholding therapy on the basis of distant extension is uncommon. Most excluded patients received simpler therapies: conventional surgery or radiotherapy, with hedgehog inhibitors being a new option.

Vaginal involvement in a woman with Darier's disease: a case report.

BACKGROUND: Involvement of the female genital tract by Darier's disease, an unusual genodermatosis, is uncommon, and the manifestation of the disease in a cervicovaginal smear is exceptionally rare. CASE: A 39-year-old woman had an abnormal Pap smear caused by involvement of the female genital tract by Darier's disease. Cytologic examination showed features consistent with a low grade squamous intraepithelial lesion, but during a biopsy it was found to be vaginal involvement by Darier's disease. CONCLUSION: The correct interpretation of cytologic findings is not possible when the diagnosis of Darier's disease is not known since a low grade squamous intraepithelial lesion cannot be ruled out. This case underlines the importance of knowing the patient's medical histoiy in any moment of medical attention.

Blue nevus with satellitosis mimicking malignant melanoma.

Blue nevus rarely develops a malignant melanoma. The loss of the regular border and the development of satellite lesions are ominous clinical indicators of the malignant change. A case is presented in which both of these clinical features--irregular border and satellite lesions--were present, but no malignant change was observed histopathologically. To our knowledge, such a single nodule with satellite lesions mimicking malignant melanoma has not been described previously.
