RESUMEN
OBJECTIVE(S): To evaluate the frequency of nonmelanoma skin cancer (NMSC), NMSC precursors, and melanoma on a store-and-forward dermatology model featuring the pharmacist as the patient's point-of-contact. The secondary objective was to define lesion changes and symptoms perceived by patients (clinical prediction rules by nonexpert observers) that can be predictive of malignity. METHODS: A cross-sectional study of teledermatology consultation was performed. All patients who underwent a teledermatology consultation between September 2018 and March 2020 were included. A patient could have more than 1 lesion per consultation. The object of the study was a defined dermatologic lesion. The differences between the variables were analyzed using a univariate model based on the chi-square test for independent qualitative variables and Fisher exact test in cases when the expected values in any of the cells of a contingency table were less than 5. Statistical significance was set at P < 0.05 (2-tailed). RESULTS: A total of 225 lesions in 218 patients were considered for this study; 53.8% (n = 121) of the lesions were classified as benign, 16.4% (n = 37) as dubious, 23.1% (n = 52) as NMSC precursors, 5.8% (n = 13) as NMSC, and 0.9% (n = 2) as melanomas. Of the reported clinical lesion changes, spontaneous pain, pruritus, surface texture changes, color changes, or form changes had no statistically significant relationship with the diagnostic group, whereas the presence of spontaneous bleeding (P = 0.015) and size changes (P = 0.026) were more frequently observed in the "dubious lesion" and "of oncological relevance lesion" groups. CONCLUSION: This "direct-to-consumer," store-and-forward teledermatology with dermoscopy model featuring the pharmacist as the patient's point-of-contact is useful for the diagnosis of melanoma, NMSC, and NMSC precursors when backed by a robust dermatology service.

Desmoplastic giant congenital melanocytic nevus (DGCN) is an uncommon variant of congenital nevus, presenting as a progressive induration and hypopigmentation of the lesion that occasionally causes hair loss and even total or partial disappearance of the nevus. A 6-month-old girl with a giant congenital melanocytic nevus that involved the entire posterior side of the right thigh was seen in our department. Nine months later, the peripheral area of the nevus presented as a marked induration with hypopigmentation. Dermoscopy demonstrated a reticular pattern exclusively located in the perifollicular areas, with a radial distribution from the follicular ostium that mimicked a "sky full of stars." We report a case of DGCN, including a dermoscopic description of the findings noted in the indurated and hypopigmented areas that appear as a "sky full of stars" image.

Non-melanoma skin cancers (NMSCs) are the most frequent group of malignant tumours worldwide. Objectives: The aim of the present research was to analyse mortality associated with NMSC in Spain between 1979 and 2018 and highlight changes regarding trend in mortality and differences according to age groups and gender. Death records and mid-year population data were collected from the National Statistics Institute. Age-standardized mortality rates were calculated. Significant changes in mortality trends were identified using Joinpoint regression. The independent effects of age, period and cohort and potential years of life lost due to NMSC were also analysed. Mortality rates associated with NMSC in Spain were reported as 2.49 per 100,000 inhabitants in 1979 (95% CI: 2.24-2.77) and 1.27 per 100,000 inhabitants in 2018 (95% CI; 1.16-1.39) for the overall population. Women who were born after the 70 s showed a significant increase in relative risk of death due to NMSC. Mortality associated with NMSC in Spain shows a decreasing overall trend that appears to have stabilized since 2005, with the exception of women between 35 and 64 years old.
RESUMEN
INTRODUCTION AND OBJECTIVES: Primary cutaneous B-cell lymphoma (CBCL) is a very low prevalence neoplasm and constitutes 25% of all primary cutaneous lymphomas. Our objective was to discover the epidemiological, clinic and histologic characteristics of CBCL in our area. METHODS: Retrospective descriptive study with patients with histologic diagnosis of CBCL followed up in our department between 2004 and 2015. RESULTS: Twenty-two patients with CBCL were included; 65% were men and 35% were women. Follicle centre lymphoma was the most common subtype (41%). Only 3 cases presented with node involvement and one with bone marrow invasion. Five recurrences were detected and one patient died because of the CBCL. DISCUSSION AND CONCLUSIONS: This is one of the first CBCL series in theSpanish population. The incidence, sex, age, subtype distribution, clinical features and immunohistochemical patterns are very similar to those of the other series.

Introducción y objetivos: El linfoma B cutáneo primario (LBCP) es una neoplasia de muy baja prevalencia y supone un 25% de todos los linfomas cutáneos. Nuestro objetivo era conocer las características epidemiológicas, clínicas e histológicas de los LBCP de nuestra área sanitaria. Métodos: Estudio descriptivo retrospectivo con datos de los pacientes con diagnóstico anatomopatológico de LBCP seguidos entre los años 2004 y 2015 en el Hospital Universitario Virgen del Rocío. Resultados: Se incluyeron 22 casos de pacientes con LBCP. El 65% eran varones frente a un 35% de mujeres. El linfoma centrofolicular supuso el subtipo más frecuente (41%). Tres casos desarrollaron afectación ganglionar y uno, invasión de la médula ósea. Durante el seguimiento se observaron 5 recidivas y un paciente falleció a causa de su LBCP. Discusión y conclusiones: Aportamos una de las primeras series de pacientes con LBCP descritas en población española. La incidencia detectada en nuestra área es similar a las de otras poblaciones descritas en la literatura. Respecto al sexo, la edad, la distribución por subtipos y la presentación clínica e inmunohistoquímica, también se obtuvieron datos similares a los de otras series (AU)
