Resumen Introduccion El uso de la ecografia Doppler (ED) se ha afianzado en los ultimos cinco anos en dermatologia. En este trabajo se describen las particularidades del uso de la ED en Cataluna y Aragon. Material y metodos Estudio descriptivo observacional transversal que se realizo en 11 hospitales de Cataluna y Aragon. Durante 5 dias habiles consecutivos en octubre de 2016, se incluyeron pacientes de todas las edades y de ambos sexos, a los que se les realizo una ED. Se excluyeron pacientes con lesiones menores de 0,1mm y/o planas pigmentadas. Resultados Participaron 17 dermatologos, 10 varones y 7 mujeres. La mediana de edad fue de 41 anos (rango: 28-49 anos). La mediana de tiempo de utilizacion de la ED era de 17 meses (rango 2-47 meses). De los 11 hospitales, 7 tenian una consulta monografica de ED. Se realizaron 150 ED a 150 pacientes, lo cual supone una frecuencia de 2,9 ecografias/hospital/dia. Noventa pacientes eran mujeres. La mediana de edad fue de 47 anos (rango 4 meses a 83 anos). Siete (60%) de los centros participantes disponian de atencion pediatrica. Las sospechas diagnosticas al realizar la ED fueron: tumores benignos 35%, enfermedades inflamatorias 21%, hidrosadenitis supurativa 18%, tumores malignos 12%, otras patologias 9% y lesiones vasculares 5%. Conclusiones La ED es una herramienta ampliamente utilizada entre los dermatologos de las comunidades de Cataluna y Aragon. Se aplica para enfermedades inflamatorias y tumorales. Es util para orientar el diagnostico, decidir una terapeutica o documentar una lesion. Introduction Doppler ultrasound (DU) is an imaging technique that has been increasingly used in dermatology during the last five years. This paper describes the characteristics of the use of DU in dermatology departments in Catalonia and Aragon. Material and methods A cross-sectional observational and descriptive study was conducted in 11 hospitals in Catalonia and Aragon. During 5 consecutive working days in October 2016, all patients who underwent cutaneous ultrasound were included. Patients with lesions smaller than 0.1mm and / or pigmented macular lesions were excluded. Results A total of 17 dermatologists, 10 men and 7 women, participated. The median age was 41 years (range: 28-49 years). Their median experience in the use of ultrasound was 17 months (range 2-47 months). There was a specific day and time to perform ultrasound in 7 of the 11 hospitals. A total of 150 DU were performed on 150 patients, with a frequency of 2.9 ultrasounds/hospital/day. Ninety patients were women. The median age of the patients was 47 years (range 4 months to 83 years). Seven (60%) of the participating hospitals had a paediatric unit. The diagnostic suspicions when performing the DU were: benign tumours 35%, inflammatory diseases 21%, hidradenitis suppurativa 18%, malignant tumours 12%, other pathologies 9%, and vascular injuries 5%. Conclusions DU is a widely used tool among dermatologists in the communities of Catalonia and Aragon. It is indicated for inflammatory and neoplastic diseases. In recent years the use of DU in Spain has increased significantly. In our work, we were able to describe the use of dermatological ultrasound in the communities of Catalonia and Aragon and compare these data with other Spanish findings.

Kaposi's sarcoma (KS) associated with AIDS (AIDS-KS) is the most prevalent neoplasia among patients with AIDS. Its incidence has decreased dramatically in recent years due to the widespread use of highly active antiretroviral therapy (HAART). Paradoxically, in relation to the introduction of HAART it may occur a worsening or development of AIDS-KS despite the improvement of the immune function. This unusual process is called immune reconstitution syndrome in Kaposi's sarcoma (IRIS-KS) and should not be confused with a failure of HAART. Early identification of AIDS-KS and previous or combined use of chemotherapy with HAART appears to be the most effective treatment to prevent the consequences of IRIS-SK.

Background: Dermoscopy, diagnostic cytology, confocal microscopy are used to improve diagnostic accuracy. Frozen section techniques have been used to control margins but not for diagnosis. Objectives: We used a new frozen section technique called immediate cutaneous diagnosis for nonmelanoma skin cancer, assessing its feasibility and accuracy in obtaining a result within 15 minutes and recording limitations. Methods and Materials: An observational, prospective clinical study was designed. Biological samples were divided into two: one half was included in paraffin, following the standard procedure, and immediate cutaneous diagnosis was applied in the other. Fresh tissue was examined by frozen sections with perpendicular slides and staining with toluidine blue. Two hundred and sixty patients were enrolled. Results: Immediate cutaneous diagnosis-toluidine blue had a sensitivity of 98.7% (95%CI: 93.0-100%) and a specificity of 92.6% (95%CI: 87.4-96.1%) in detecting nonmelanoma skin cancer. Inter-rater agreement between two dermatopathologists using Cohen's kappa was 0.796 (P
