¿Cuánta carga asistencial suponen las dermatosis pediátricas en la actividad ambulatoria en la dermatología española? Resultados del muestreo aleatorio nacional DIADERM / What Proportion of the Spanish Dermatology Caseload Corresponds to Pediatric Dermatoses? Results From the DIADERM National Random Sampling Survey

Introducción Los motivos de consulta de índole dermatológico son muy frecuentes en las consultas de pediatría de atención primaria, e igualmente muchos de los pacientes atendidos en consultas de dermatología son niños y adolescentes. A pesar de ello, faltan estudios sobre la prevalencia real de estas consultas y sus características. Material y método Estudio observacional de corte transversal de 2 períodos de tiempo describiendo los diagnósticos realizados en consultas externas dermatológicas, obtenidos a través de la encuesta anónima DIADERM, realizada a una muestra aleatoria y representativa de dermatólogos. A partir de la codificación de diagnósticos CIE-10, se seleccionaron todos los diagnósticos codificados en los menores de 18 años (84 diagnósticos codificados en los 2 períodos), que se agruparon en 14 categorías diagnósticas relacionadas para facilitar su análisis y comparación. Resultados Un total de 20.097 diagnósticos fueron efectuados en pacientes menores de 18 años, lo que supone un 12% del total de los codificados en DIADERM. Las infecciones víricas, el acné y la dermatitis atópica fueron los diagnósticos más comunes (43,9% de todos los diagnósticos). No se observaron diferencias estadísticamente significativas en la proporción de diagnósticos atendidos en las consultas monográficas frente a las generales, así como en los registrados en el ámbito público frente al privado. Tampoco las hubo en los diagnósticos en función de la época de la encuesta (enero y mayo). Conclusiones La atención a pacientes pediátricos por parte de dermatólogos en España supone una proporción significativa de la actividad habitual. Estos datos nos permiten descubrir áreas de mejora en la comunicación y la formación de los pediatras de atención primaria, como la necesidad del refuerzo de actividades formativas dirigidas al mejor tratamiento de acné y lesiones pigmentadas (y manejo básico de la dermatoscopia) en este ámbito asistencial (AU)

Background Visits for skin conditions are very common in pediatric primary care, and many of the patients seen in outpatient dermatology clinics are children or adolescents. Little, however, has been published about the true prevalence of these visits or about their characteristics. Material and methods Observational cross-sectional study of diagnoses made in outpatient dermatology clinics during 2 data-collection periods in the anonymous DIADERM National Random Survey of dermatologists across Spain. All entries with an International Classification of Diseases, Tenth Revision code related to dermatology in the 2 periods (84 diagnoses) were collected for patients younger than 18 years and classified into 14 categories to facilitate analysis and comparison. Results In total, the search found 20 097 diagnoses made in patients younger than 18 years (12% of all coded diagnoses in the DIADERM database). Viral infections, acne, and atopic dermatitis were the most common, accounting for 43.9% of all diagnoses. No significant differences were observed in the proportions of diagnoses in the respective caseloads of specialist vs. general dermatology clinics or public vs. private clinics. Seasonal differences in diagnoses (January vs. May) were also nonsignificant. Conclusions Pediatric care accounts for a significant proportion of the dermatologist's caseload in Spain. Our findings are useful for identifying opportunities for improving communication and training in pediatric primary care and for designing training focused on the optimal treatment of acne and pigmented lesions (with instruction on basic dermoscopy use) in these settings (AU)

Enfermedades infecciosas no venéreas atendidas en consultas de Dermatología en España: resultados del estudio DIADERM / Nonvenereal Infections in Spanish Dermatology Clinics: Results of the DIADERM Study

Antecedentes y objetivo El peso e impacto de las enfermedades infecciosas no venéreas en Dermatología no ha sido evaluado hasta el momento en nuestro medio. El objetivo de este estudio es analizar su prevalencia global en el ámbito de la asistencia ambulatoria dermatológica. Material y métodos Estudio observacional de corte transversal de los diagnósticos realizados en consultas de Dermatología por una muestra aleatoria de dermatólogos de la Academia Española de Dermatología y Venereología (AEDV). Los datos fueron obtenidos a partir de la encuesta anónima DIADERM. Se seleccionaron los diagnósticos correspondientes a enfermedades infecciosas, codificados mediante el sistema CIE-10. Se excluyeron las infecciones de transmisión sexual y los diagnósticos restantes se clasificaron en 22 grupos diagnósticos. Resultados Se estimó que los dermatólogos españoles hacen 16.190 diagnósticos de patología infecciosa no venérea en una semana laboral (IC 95%, 9.338-23.042), lo que representaba el 9,33% del total de las consultas dermatológicas. Las verrugas víricas fuera de la región anogenital (7.475, 46,17% de las infecciones), las dermatofitosis (3.336, 20,61% de las infecciones) y «otras infecciones víricas», donde se incluía la infección por Molluscum contagiosum (1.592, 9,84%), fueron los diagnósticos más frecuentes. En la comparativa frente a la patología no infecciosa, las infecciones cutáneas fueron más frecuentes en el ámbito de las consultas privadas (p<0,0020) y en los pacientes adultos (p<0,00001). Los pacientes con infecciones cutáneas recibieron el alta con mayor frecuencia que los pacientes con otras patologías, tanto en el sistema público (p<0,0004) como en el privado (p<0,0002) (AU)

Background and objective The burden of nonvenereal infections in Spanish dermatology practice has not yet been evaluated. The aim of this study was to analyze the overall weight of these infections in outpatient dermatology caseloads.Material and methods Observational cross-sectional study of diagnoses made by a random selection of dermatologists from the Spanish Association of Dermatology and Venereology (AEDV) working in outpatient dermatology clinics. The data were obtained through the anonymous DIADERM survey. Diagnoses of infectious diseases were selected using codes from the International Classification of Diseases, Tenth Revision. After excluding sexually transmitted infections, the diagnoses were classified into 22 groups. Results Spanish dermatologists diagnosed an estimated 16190 (95% CI, 9338-23042) nonvenereal infections on average per week, a figure that accounted for 9.33% of the dermatology caseload. The most common diagnostic groups were nonanogenital viral warts (7475 diagnoses, 46.17% of nonvenereal infections), dermatophytosis (3336, 20.61%), and other viral infections (1592, 9.84%), which included Molluscum contagiosum infections. Nonvenereal infections were more common than noninfectious dermatologic conditions in private clinics (P<.0020) and adults (P<.00001). Patients with these infections were also more likely to be discharged than those with other conditions in both public (P<.0004) and private (P<.0002) practices. Conclusions Nonvenereal infections are frequent in dermatology. They are the third most common reason for outpatient visits, behind actinic keratosis and nonmelanoma skin cancer. By enhancing the participation of dermatologists in the management of skin infections and encouraging interactions with other specialists, we will be able to carve out a niche in an area we have scarcely ventured into to date (AU)

¿Cuánta carga asistencial suponen las infecciones de transmisión predominantemente sexual y otras dermatosis anogenitales en las consultas de Dermatología en España? Resultados del muestreo aleatorio nacional DIADERM / What Proportion of the Spanish Dermatology Caseload Corresponds to Primarily Sexually Transmitted Infections and Other Anogenital Dermatoses? Results From the DIADERM National Random Survey

Introducción: Las infecciones e infestaciones de transmisión predominantemente sexual y otras dermatosis anogenitales forman parte de la formación específica de los médicos especialistas en Dermatología y Venereología en España. El presente estudio pretende analizar la carga que suponen dichas patologías en la actividad dermatológica pública y privada del sistema de salud español. Material y método: Estudio observacional de corte transversal de dos períodos de tiempo describiendo los diagnósticos realizados en consultas externas dermatológicas, obtenidos a través de la encuesta anónima DIADERM, realizada a una muestra aleatoria y representativa de dermatólogos. A partir de la codificación de diagnósticos CIE-10, se seleccionó toda la patología relacionada (36 diagnósticos codificados en los dos períodos), que se clasificó en 12 grupos. Resultados: Tan solo el 3,16% de los diagnósticos globales fueron de infecciones e infestaciones de transmisión predominantemente sexual y otras dermatosis anogenitales. Los 3 grupos diagnósticos más frecuentes fueron las lesiones por virus del papiloma humano anogenital, seguido de los molluscum contagiosum y las dermatosis anogenitales inflamatorias. Con significación estadística, y comparando con el global de diagnósticos, los seleccionados constituyeron más habitualmente el motivo de consulta primario y, en el ámbito privado, fue más frecuente que viniesen derivados de otros especialistas. Conclusión: Las infecciones e infestaciones de transmisión predominantemente sexual y otras dermatosis anogenitales tienen un peso muy limitado en la asistencia dermatológica en España, a pesar de que la inclusión del diagnóstico de molluscum contagiosum sobreestima estos diagnósticos. La ausencia de inclusión de centros y consultas monográficas de ITS en la muestra aleatoria contribuye a la infrarrepresentación de estas parcelas de la especialidad. Es importante hacer un esfuerzo decidido por potenciarlas con consultas y centros (AU)

Background and objective: Predominantly sexually transmitted infections (STIs) and infestations and other anogenital dermatoses are covered in the training of specialists in dermatology and venereology in Spain. This study aimed to analyze the proportion of the dermatology caseload these diseases account for within the public and private dermatological activity of the Spanish health system. Material and methods: Observational cross-sectional study of time periods describing the diagnoses made in outpatient dermatology clinics, obtained through the anonymous DIADERM survey of a representative random sample of dermatologists. Based on diagnostic codes of the International Classification of Diseases, Tenth Revision, 36 related diagnoses were selected, and classified into 12 groups. Results: Only 3.16% of diagnoses corresponded to STIs and other anogenital dermatoses. The most common diagnostic group was anogenital human papillomavirus infection, followed by molluscum contagiosum, and inflammatory anogenital dermatoses. Lesions with these diagnoses were usually the main reasons for first visits in the National Health Service. In private practice, the diagnoses usually came after referrals from other physicians. Conclusions: STIs and other anogenital dermatoses account for a very small proportion of the dermatology caseload in Spain, although the inclusion of molluscum contagiosum diagnoses overestimates these conditions. The fact that no STI centers or monographic STI consultations were included in the random sample of dermatology partly explains the under-representation of these areas of the specialty. A determined effort to support and promote monographic STI centres and clinics should be made (AU)

Position statement on classification of basal cell carcinomas. Part 1: unsupervised clustering of experts as a way to build an operational classification of advanced basal cell carcinoma based on pattern recognition.

BACKGROUND: No simple classification system has emerged for 'advanced basal cell carcinomas', and more generally for all difficult-to-treat BCCs (DTT-BCCs), due to the heterogeneity of situations, TNM inappropriateness to BCCs, and different approaches of different specialists. OBJECTIVE: To generate an operational classification, using the unconscious ability of experts to simplify the great heterogeneity of the clinical situations into a few relevant groups, which drive their treatment decisions. METHOD: Non-supervised independent and blinded clustering of real clinical cases of DTT-BCCs was used. Fourteen international experts from different specialties independently partitioned 199 patient cases considered 'difficult to treat' into as many clusters they want (≤10), choosing their own criteria for partitioning. Convergences and divergences between the individual partitions were analyzed using the similarity matrix, K-mean approach, and average silhouette method. RESULTS: There was a rather consensual clustering of cases, regardless of the specialty and nationality of the experts. Mathematical analysis showed that consensus between experts was best represented by a partition of DTT-BCCs into five clusters, easily recognized a posteriori as five clear-cut patterns of clinical situations. The concept of 'locally advanced' did not appear consistent between experts. CONCLUSION: Although convergence between experts was not granted, this experiment shows that clinicians dealing with BCCs all tend to work by a similar pattern recognition based on the overall analysis of the situation. This study thus provides the first consensual classification of DTT-BCCs. This experimental approach using mathematical analysis of independent and blinded clustering of cases by experts can probably be applied to many other situations in dermatology and oncology.

Position statement on classification of basal cell carcinomas. Part 2: EADO proposal for new operational staging system adapted to basal cell carcinomas.

BACKGROUND: No simple staging system has emerged for basal cell carcinomas (BCCs), since they do not follow the TNM process, and practitioners failed to agree on simple clinical or pathological criteria as a basis for a classification. Operational classification of BCCs is required for decision-making, trials and guidelines. Unsupervised clustering of real cases of difficult-to-treat BCCs (DTT-BCCs; part 1) has demonstrated that experts could blindly agree on a five groups classification of DTT-BCCs based on five patterns of clinical situations. OBJECTIVE: Using this five patterns to generate an operational and comprehensive classification of BCCs. METHOD: Testing practitioner's agreement, when using the five patterns classification to ensure that it is robust enough to be used in the practice. Generating the first version of a staging system of BCCs based on pattern recognition. RESULTS: Sixty-two physicians, including 48 practitioners and the 14 experts who participated in the generation of the five different patterns of DTT-BCCs, agreed on 90% of cases when classifying 199 DTT-BCCs cases using the five patterns classification (part 1) attesting that this classification is understandable and usable in practice. In order to cover the whole field of BCCs, these five groups of DTT-BCCs were added a group representing the huge number of easy-to-treat BCCs, for which sub-classification has little interest, and a group of very rare metastatic cases, resulting in a four-stage and seven-substage staging system of BCCs. CONCLUSION: A practical classification adapted to the specificities of BCCs is proposed. It is the first tumour classification based on pattern recognition of clinical situations, which proves to be consistent and usable. This EADO staging system version 1 will be improved step by step and tested as a decision tool and a prognostic instrument.

¿Cuánta carga asistencial supone la enfermedad tumoral cutánea en la actividad ambulatoria en la Dermatología española? Resultados del muestreo aleatorio nacional DIADERM / What Proportion of the Caseload at Dermatology Outpatient Clinics in Spain Do Skin Tumors Account for? Results from the DIADERM National Random Sampling Project

Introducción y objetivo La patología tumoral conforma una parte esencial de la actividad dermatológica. El presente estudio pretende analizar la carga de los tumores cutáneos en la actividad dermatológica pública y privada del sistema de salud español. Material y método Estudio observacional de corte transversal de 2 períodos de tiempo describiendo los diagnósticos realizados en consultas externas dermatológicas, obtenidos a través de la encuesta anónima DIADERM, realizada a una muestra aleatoria y representativa de dermatólogos. A partir de la codificación de diagnósticos CIE-10, se seleccionó toda la patología tumoral (165 diagnósticos codificados en los 2 períodos), que se clasificó en 24 grupos, posteriormente subclasificada en patología benigna y maligna, melanocítica y no melanocítica. Resultados El 46,2% de los diagnósticos fueron de patología tumoral. El 18,5% de los diagnósticos globales se debió a tumores malignos (incluyendo entre estos diagnósticos los tumores queratinocíticos in situ). De los primeros 10 diagnósticos de patología tumoral en frecuencia, 4 eran malignos: tumores queratinocíticos in situ, carcinoma basocelular, melanoma y carcinoma espinocelular. Se encontraron algunas diferencias significativas entre tumores benignos y malignos atendiendo al ámbito de su asistencia (público/privado), así como a factores geográficos. Conclusión El cáncer cutáneo tiene un peso importante en la asistencia dermatológica en España. Se pueden observar algunas diferencias en función del ámbito de atención público/privado y de otros factores (AU)Introduction and objective

A significant part of a dermatologist's activity involves the diagnosis and management of tumors. The aim of this study was to analyze the caseload at public and private dermatology outpatient clinics in Spain to determine the proportion of tumor diagnoses. Material and method Observational cross-sectional study of diagnoses made in dermatology outpatient clinics during 2 data-collection periods in the DIADERM study, an anonymous survey of a random, representative sample of dermatologists across Spain. Diagnoses made during the 2 periods were coded according to the CIE-10. There were 165 tumor-related codes, classified into 24 groups. For the purpose of this study, these groups were then reduced to benign melanocytic lesions, malignant melanocytic lesions, benign nonmelanocytic lesions, and malignant nonmelanocytic lesions. Results Tumors accounted for 46.2% of all diagnoses; 18.5% of the tumors were malignant (a category that included in situ forms of keratinocyte cancers). Four of the 10 most common diagnoses were of malignant tumors: in situ keratinocyte cancers, basal cell carcinoma, melanoma, and squamous cell carcinoma. Significant differences were observed between malignant and benign tumors according to type of practice (public vs. private) and geographic region. Conclusion Skin cancer accounts for a significant part of the dermatologist's caseload in Spain. Differences can be observed depending on the public/private healthcare setting and other factors (AU)

The aim of this study was to analyze the caseload at public and private dermatology outpatient clinics in Spain to determine the proportion of tumor diagnoses. MATERIAL AND METHOD: Observational cross-sectional study of diagnoses made in dermatology outpatient clinics during 2 data-collection periods in the DIADERM study, an anonymous survey of a random, representative sample of dermatologists across Spain. Diagnoses made during the 2 periods were coded according to the CIE-10. There were 165 tumor-related codes, classified into 24 groups. For the purpose of this study, these groups were then reduced to benign melanocytic lesions, malignant melanocytic lesions, benign nonmelanocytic lesions, and malignant nonmelanocytic lesions. RESULTS: Tumors accounted for 46.2% of all diagnoses; 18.5% of the tumors were malignant (a category that included in situ forms of keratinocyte cancers). Four of the 10 most common diagnoses were of malignant tumors: in situ keratinocyte cancers, basal cell carcinoma, melanoma, and squamous cell carcinoma. Significant differences were observed between malignant and benign tumors according to type of practice (public vs. private) and geographic region. CONCLUSION: Skin cancer accounts for a significant part of the dermatologist's caseload in Spain. Differences can be observed depending on the public/private healthcare setting and other factors.

Risk Perception Plays Minimal Role in Sun Exposure Behaviours.

Despite decades of public health campaigns, tanning and sunburn still occur at unacceptably high rates. Skin cancer prevention campaigns predominately focus on increasing awareness of the risk of excessive sun exposure. This study sought to assess the efficacy of this approach, by interrogating correlations between risk perception and sun exposure behaviour. A 31-item questionnaire assessing skin cancer risk factors, tanning attitudes, sunburn and tanning behaviour was undertaken by individuals who attended a workplace skin check. Validated questions were included to assess cognitive and affective risk perception and to frame risk as absolute, comparative and conditional. One hundred sixty-seven respondents completed the questionnaire. No aspects of risk perception (absolute cognitive, affective or conditional) significantly correlated with protective sun exposure behaviour, with the exception of perceived comparative severity of skin cancer. Instead, positive tanning attitudes were far more significantly correlated with sun exposure behaviour. Actual risk and risk perception have very limited impact on sun exposure behaviour. Instead, sun exposure behaviour was significantly linked with positive tanning attitudes. It is suggested, therefore, that campaigns focussing solely on education regarding risk factors appear to have been ineffective in behaviour mitigation, and innovative approaches, aimed at influencing tanning norms, might complement the existing educational campaigns.

¿Existe variación en los diagnósticos dermatológicos entre la temporada de frío vs. calor? Un subanálisis del estudio DIADERM (España 2016) / Do Dermatologic Diagnosis Change in Hot vs. Cold Periods of The Year? A Sub-Analysis of the DIADERM National Sample (Spain 2016)

Antecedentes El conocimiento de las variaciones de las enfermedades dermatológicas a lo largo del año podría ser útil para la planificación en salud y el manejo de las enfermedades. Sin embargo, existe escasa información acerca de la variación de los diagnósticos dermatológicos en diferentes épocas del año en una muestra nacional representativa. Objetivos: Evaluar si existe variación en los diagnósticos clínicos dermatológicos entre la temporada de frío y calor en España. Material y métodos: Los datos se han obtenido mediante una encuesta anónima realizada a una muestra aleatoria y representativa de dermatólogos españoles estratificados por área. Cada uno de los participantes recogió todos los diagnósticos clínicos durante 6 días de consulta en 2016 (3 en la temporada de frío y 3 en la temporada de calor). Los diagnósticos se codificaron según la CIE-10. Resultados: Con una proporción de respuesta de 62%, se recolectaron 11.223 diagnósticos clínicos. Los grupos diagnóstico CIE-10 que mostraron variaciones entre temporadas fueron: otras neoplasias benignas de la piel (D23), rosácea (L71) y otros trastornos foliculares (L73), los cuales fueron más frecuentes en la temporada de calor, y acné (L70) el cual fue más frecuente en la temporada de frío. Además, describimos las diferencias en la población pediátrica y según el tipo de asistencia pública frente a privada. Algunas de estas diferencias podrían estar relacionadas con diferencias en la población que consulta en las distintas temporadas. Conclusiones: La frecuencia de la mayoría de los diagnósticos clínicos realizados por dermatólogos no sufre variaciones a lo largo del año. Solo algunos de los diagnósticos clínicos muestran variaciones entre la temporada de frío frente a calor. Estas variaciones observadas pueden estar en relación con las propias enfermedades o pueden ser debidas a cambios estacionales en la demanda de consultas dermatológicas

Background: Knowledge of seasonal variation of cutaneous disorder may be useful for heath planning and disease management. To date, however, descriptions of seasonality including all diagnoses in a representative country sample are very scarce. Objectives: To evaluate if clinical dermatologic diagnosis in Spain change in the hot vs. cold periods. Materials and methods: Survey based on a random sample of dermatologists in Spain, stratified by area. Each participant collected data during 6 days of clinical activity in 2016 (3 in the cold period of the year, 3 in the hot period). Clinical diagnoses were coded using ICD-10. Results: With a 62% response proportion, we got data on 10999 clinical diagnoses. ICD-10 diagnostic groups that showed changes were: other benign neoplasms of skin (D23), rosacea (L71) and other follicular disorders (L73), which were more common in the hot period and acne (L70) which was more frequent in the cold period. We describe differences in the paediatric population and in private vs. public practice. Some of these differences might be associated to differences in the population demanding consultations in different periods. Conclusions: The frequency of most clinical diagnosis made by dermatologists does not change over the year. Just a few of the clinical diagnoses made by dermatologists show a variation in hot vs. cold periods. These variations could be due to the diseases themselves or to seasonal changes in the demand for consultation

Análisis de la proporción de derivaciones potencialmente evitables desde Atención Primaria a Dermatología por lesiones quísticas o tumorales benignas en España. Datos del estudio DIADERM / Proportion of Potentially Avoidable Referrals From Primary Care to Dermatologists for Cystic Lesions or Benign Neoplasms in Spain: Analysis of Data From the DIADERM Study

Antecedentes y objetivo: Las lesiones cutáneas constituyen un motivo de consulta frecuente en Atención Primaria (AP). Aquellas que no supongan un problema de salud, sino una cuestión estética, no deben ser tratadas en el Sistema Nacional de Salud, según la legislación vigente. El objetivo de este trabajo es estimar qué porcentaje de derivaciones remitidas desde AP a Dermatología por lesiones quísticas o tumores benignos corresponde a lesiones que podríamos considerar potencialmente evitables. Material y método: Utilizamos los diagnósticos principales de los pacientes derivados de AP, recogidos en el estudio representativo nacional DIADERM. Cada uno de los diagnósticos derivados fue clasificado como potencialmente evitable si se correspondía con alguno de los diagnósticos con criterio de alta desde AP, establecidos en el documento de consenso propuesto por la sección territorial andaluza de la Academia Española de Dermatología y Venereología. Resultados: Se recogieron datos de 2.171 motivos principales de consulta derivados de AP como primeras consultas. De estos, 686 (31,6%) son diagnósticos que podrían corresponderse con derivaciones potencialmente evitables por lesiones quísticas o tumorales benignas. Un 22% (478) del total de las consultas fueron dadas de alta en la primera visita. Los diagnósticos más frecuentes entre estos fueron las queratosis seborreicas (9,3%) y los nevus melanocíticos (8,6%). Conclusiones: La proporción de derivaciones potencialmente evitables a Dermatología desde AP por lesiones quísticas y tumorales benignas supone casi un tercio de las consultas. El conocimiento de la realidad asistencial de nuestro entorno puede ser útil para mejorar la planificación, la formación y la gestión sanitaria

Background and objective: Skin lesions are a common reason for consulting a primary care physician. Current legislation in Spain states that purely aesthetic skin problems that do not pose a health problem are not to be treated within the National Health Service. The aim of this study was to estimate the proportion of referrals from primary care physicians to dermatologists that were for cystic lesions or benign tumors and could potentially have been avoided. Material and methods: We consulted cases registered in the DIADERM study dataset, which is representative of dermatology practice in Spain, and collected the main diagnoses given on referring patients from primary care. A referral diagnosis was classified as potentially avoidable if it corresponded to one of the primary care discharge diagnoses listed in a consensus paper of the Andalusian section of the Spanish Academy of Dermatology and Venereology (AEDV). Results: We collected 2171 main reasons for first-visit referrals to dermatologists; 686 of them (31.6%) were for cystic lesions or benign tumors and classified as potentially avoidable. In 478 cases (22%) the patients were discharged on the first visit. The most frequent diagnoses in such cases were seborrheic keratosis (9.3%) and melanocytic nevus (8.6%). Conclusions: Nearly a third of referrals from primary care to a dermatologist were for cystic lesions and benign tumors and could have been avoided. A clearer understanding of our caseload can be useful for improving planning, training, and health care system management
