RESUMO
Objetivo: Los pacientes diagnosticados de cáncer queratinocítico (carcinoma basocelular y carcinoma epidermoide cutáneo) o cáncer cutáneo no melanoma (CCNM) tienen un riesgo aumentado de desarrollar una segunda neoplasia cutánea. Nuestro objetivo es describir la frecuencia, tasa de incidencia y factores de riesgo predisponentes para desarrollar una segunda neoplasia cutánea en una cohorte de pacientes tratados mediante cirugía micrográfica de Mohs (CMM). Material y métodos: Estudio prospectivo de una cohorte nacional de pacientes incluidos para realización de CMM para tratar CCNM en 22 centros españoles (julio 2013-febrero 2020) REGESMOHS. Las variables analizadas incluyen las características demográficas, la frecuencia de aparición de segundas neoplasias cutáneas, sus tasas de incidencia y factores de riesgo, y se estimaron utilizando un modelo de regresión logístico multivariante de efectos mixtos. Resultados: Fueron intervenidos 4.768 pacientes: 4.397 (92%) carcinomas basocelulares, y 371 (8%) carcinomas epidermoides. El tiempo medio de seguimiento fue de 2,4 años. Se diagnosticó un nuevo tumor durante el seguimiento en 1.201 pacientes (25%); 1.013 (21%) fueron carcinomas basocelulares, 154 (3%) carcinomas epidermoides cutáneos, 20 melanomas (0,4%) La tasa de incidencia fue de 107 (101-113) por 1.000 personas/año para cualquier tumor; 90 (85-96) para el carcinoma basocelular, 14 (12-16) para el carcinoma epidermoide cutáneo y 2 (1-3) para el melanoma. El riesgo de nueva neoplasia fue mayor en varones que en mujeres 738 (61%) vs. 463 (39%). Los factores de riesgo más significativos fueron la historia de múltiples tumores previos al diagnóstico (RR: 4,6; IC 95%: 2,9-7,1); la inmunosupresión (RR: 2,1; IC 95%: 1,4-3,1) y paciente varón (RR: 1,6; IC 95%: 1,4-1,9) (AU)
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 (AU)

Ectropion, or eyelid eversion, is the most common form of eyelid malposition. By impairing the eyelid's protective function, ectropion can cause epiphora, lagophthalmos, keratinization, chronic irritation, pain, and ulceration. There are 5 types of ectropion, each with a different cause: congenital, paralytic, involutional, cicatricial, and mechanical. The most common presentation in dermatology is involutional eversion with a mechanical or tractional element. Several options exist for the surgical repair of ectropion and choice of technique will depend on the main pathogenic component. We review the basic anatomy of the eyelid and describe examination techniques for assessing risk and preventing ectropion and for identifying the main pathogenic component in order to select the most suitable repair technique.

BACKGROUND: Surgery is the treatment of choice in basal cell carcinoma (BCC), but new less invasive techniques are in development such as photodynamic therapy. The main problem of this technique is the limited depth penetration of topical photosensitizers. The use of an intralesional photosensitizer plus an irradiation with a 630â¯nm laser should increase this penetration. OBJETIVES: To compare the effectiveness in treatment of BCC between surgery and intralesional photodynamic therapy (I-PDT). To identify the clearance rate differences between intralesional or external irradiation in I-PTD group. METHODS: A retrospective study of 102 patients with different histological types of BCC (mean depth of 2.44â¯mm) was performed. A total of 51 patients were treated with surgery and 51 with I-PDT, injecting 5-aminolevulinic acid 1% in the tumor and later irradiated with a 630â¯nm laser (intralesionally or externally: 25 and 26 patients respectively). Histological samples were obtained before and after treatment. RESULTS: A total of 41/51 Patients in the surgery group vs 42/51 patients in I-PDT group achieved a complete clearance after treatment (p 0.79). There were no differences in success rates between intralesional vs external irradiation in I-PDT group (p 0.46). LIMITATIONS: Small sample size and retrospective study. CONCLUSION: I-PDT achieved high clearance rates in the treatment of BCC similar to surgery. There were no differences in success rates between intralesional vs external irradiation in I-PDT group. PDT might be an interesting option of treatment where surgery it is not possible.
