RESUMO

Introducción: Uno de los retos más difíciles en el campo de la Dermatología laboral es la identificación de las sustancias químicas con las que trabaja el enfermo para poder determinar su capacidad alergénica. Se han descrito múltiples técnicas para poder identificar las distintas sustancias alergénicas contenidas en la composición de las sustancias que maneja el enfermo. Estas pruebas de detección de alérgenos deben ser sensibles, específicas y seguras. Presentamos un estudio experimental cuyo objetivo es detectar la presencia de parafenilendiamina entintes capilares comercializados en nuestro país. Material y métodos: Hemos realizado un estudio experimental con el fin de realizar una detección cualitativa y semicuantitativa de parafenilendiamina en tintes capilares comercializados en nuestro país. Como técnica cualitativa utilizamos la técnica de identificación descrita consistente en la dilución del tinte con alcohol isopropílico y con posterioridad se añade la solución reactiva (1 g de vainilla en 15 ml de alcohol isopropílico y 7,5 ml de ácido clorhídrico). Esta prueba da una respuesta colorimétrica que indica la presencia o no del alérgeno en el tinte capilar. Con posterioridad hemos procedido a realizar un estudio cualitativo mediante la extracción del colorante con etanol 96◦, seguido de una cromatografía en capa fina monodimensional. Resultados: Se estudiaron un total de 15 tintes de color castaño o moreno y 12 tintes de color rubio. Este estudio nos permitió identificar la PPD en todos los tintes capilares morenos estudiados, con independencia de que su presencia estuviera indicada (n=12) o no (n=3) en la composición del tinte. Comprobamos la presencia de PPD en 6 de los 9 tintes rubios que indicaban la presencia de PPD en su composición y en 2 de los 3 que no la indicaban. La valoración semicuantitativa mediante cromatografía de capa fina nos permitió confirmar que la concentración de PPD utilizada en los tintes capilares de color moreno era superior (media del 3%) a la de los tintes rubios (media del 0,1-0,3%). Conclusión: La presencia de PPD en tintes capilares está en relación con la coloración del tinte, siendo constante en los de color oscuro y de intensidad baja en los rubios. Este estudio pone de manifiesto la importancia clínica y epidemiológica que tiene la identificación de alérgenos en la Dermatología, y de forma más concreta, en el campo de la Dermatología laboral (AU)


Background: One of the greatest challenges in occupational dermatology is the identification of chemical substances used by patients in their work in order to determine their allergenic potential. Numerous techniques have been described for the identification of allergenic compounds. These tests must be sensitive, specific, and safe. We describe a study to detect the presence of paraphenylenediamine (PPD) in hair dyes that are commercially available in Spain. Material and methods: We undertook an experimental study involving qualitative and semiquantitative detection of PPD in hair dyes sold in Spain. The qualitative technique we used was a previously described colorimetric method involving dilution of the dye with isopropyl alcohol followed by addition of a reagent solution (1 g of vanilla in 15 ml of isopropyl alcohol and 7.5 ml of hydrochloric acid). A quantitative study was then done in which the dye was extracted in 96% ethanol and subjected to 1-dimensional thin-layer chromatography. Results: A total of 15 brown and 12 blonde dyes were analyzed. PPD was identified in all of the brown dyes analyzed, irrespective of whether it was indicated (n = 12) or not (n = 3) in the composition. PPD was found in 6 of the 9 blonde dyes that indicated it in the composition and 2of the 3 in which it was not indicated. Semiquantitative analysis by thin-layer chromatography revealed that the concentration of PPD in brown hair dyes (mean, 3%) was higher than in blonde dyes (mean, 0.1-0.3%). Conclusions: The presence of PPD in hair dyes is related to the color of the dye. It is consistently present in darker dyes and at low levels in blonde dyes. This study highlights the clinical and epidemiological importance of identifying allergens in dermatology, particularly in occupational dermatology (AU)

RESUMO

BACKGROUND: The epidemiology of contact dermatitis can be analyzed using clinical data from skin allergy units. OBJECTIVES: The aims of this study were to define the profile of patients attending a skin allergy unit and to determine the prevalence of the most common sensitizations in this population. MATERIAL AND METHODS: Throughout 2008, a retrospective observational study was carried out in the 5 hospitals of the Spanish Surveillance System on Contact Allergies. All patients underwent skin patch tests with the Spanish standard series. The frequencies of sensitization were normalized for age and gender. RESULTS: Data were gathered on 1161 patients. The 5 allergens that gave the most frequent positive reactions were nickel sulfate (25.88%), potassium dichromate (5.31%), cobalt chloride (5.10%), fragrance blends (4.64%), and balsam of Peru (4.44%). The least frequently detected reactions were to quinolone-clioquinol mix and sesquiterpene lactone mix. There was a 35% prevalence of sensitization to nickel among women. CONCLUSIONS: The profile of sensitizations in Spain is similar to that of other Southern European countries. Nickel sulfate continues to be the most prevalent allergen, particularly in women. The low prevalence of sensitization to quinolone-clioquinol mix and sesquiterpene lactone mix supports their exclusion of the Spanish series.

RESUMO

Introducción: el estudio epidemiológico del eczema de contacto puede realizarse mediante el análisis de los datos obtenidos a partir de la experiencia clínica de las unidades de alergia cutánea. Objetivo: determinar el perfil de los pacientes que acuden a una unidad de alergia cutánea y determinar la prevalencia de sensibilizaciones más frecuente en esta población. Material y métodos: estudio observacional retrospectivo de los 5 hospitales pertenecientes a la Red Española de Vigilancia de Alergia de Contacto (REVAC) durante el año 2008. Todos los pacientes fueron estudiados mediante pruebas epicutáneas con la serie estándar española. Las frecuencias de sensibilización se han estandarizado por sexo y edad. Resultados: se recogieron datos de 1.161 pacientes. Los 5 alérgenos que presentaron positividades más frecuentemente fueron sulfato de níquel (25,88%), dicromato potásico (5,31%), cloruro de cobalto (5,10%), mezcla de fragancias (4,64%) y bálsamo del Perú (4,44%). Los alérgenos menos frecuentes fueron la mezcla de quinoleínas/clioquinol y la mezcla de lactonas sesquiterpénicas. En las mujeres la prevalencia de sensibilización al níquel fue del 35%. Conclusiones: el perfil de sensibilizaciones de España es el esperado para un país del Sur de Europa. El sulfato de níquel sigue siendo el alérgeno más prevalente, siendo especialmente importante en mujeres. La mezcla de quinoleínas/clioquinol y la mezcla de lactonas sesquiterpénicas no han mostrado rentabilidad suficiente para su permanencia en la serie española (AU)

RESUMO

El eczema de contacto es un problema médico frecuente, con una prevalencia poblacional elevada. Esto implica un importante problema de salud con un impacto a nivel personal, social y económico. Por ello, es necesario invertir esfuerzos en iniciativas de investigación clínica y epidemiológica que nos ayuden a conocer la realidad del eczema de contacto en España. En el presente trabajo se aborda la investigación epidemiológica del eczema de contacto desde el punto de vista práctico, analizando el papel del dermatólogo a la hora de planificar y diseñar estudios en este campo. Se discuten además las ventajas de los trabajos multicéntricos y el rol de las redes de vigilancia epidemiológica tanto a nivel nacional como internacional. Finalmente, se presenta la Red Española de Vigilancia de Alergia de Contacto, nexo entre los dermatólogos españoles y la European Surveillance System in Contact Allergies, definiendo sus objetivos presentes y futuros (AU)

RESUMO

A 32-year old patient presented with an asymptomatic, non-specific tumour located at the site of a previous cesarian scar. The tumor had never bled but its size changed and the color and consistency varied coinciding with the menstrual cycle. The dermatopathologic study showed the existence of ectopic endometrial glandular tissue in the whole thickness of the reticular dermis.

RESUMO

La paniculitis lipomembranosa o esteatonecrosis membranoquística es una alteración del tejido adiposo que se suelen manifiestar en forma de placasescleróticas de tendencia crónica, localizadas en la parte inferior de las piernas. Es casi exclusiva de mujeres en su mayoría obesas, diabéticas y con unsevero componente de estasis venoso. Los hallazgos histológicos característicos son los de una paniculitis lobulillar en la que por confluencia se vanformando cavidades quísticas, rodeadas de tejido graso con signos claros de esteatonecrosis. Presentamos el caso de una mujer de 36 años que habíadesarrollado en la zona de un traumatismo previo una lesión dolorosa que a la palpación estaba constituida por múltiples formaciones nódulo-quísticas.El estudio dermatopatológico puso de manifiesto la presencia de estructuras quísticas localizadas en los lóbulos y a nivel de los septos, rodeadasde tejido graso, con signos evidentes de esteatonecrosis, presencia significativa de histiocitos espumosos y rotura de las membranas celulares con formaciónde microquistes. Las cavidades quísticas estaban delimitadas en su cara interna por una membrana serpiginosa, anuclear, homogénea y eosinofílica,PAS+, de aspecto granulado, que incluso en algunas áreas llegaba a formar pseudopapilas que se proyectaban hacia el interior del quiste. Seha sugerido que la isquemia es la causa patogénica fundamental de la paniculitis lipomembranosa, aunque también se especulan otros factores comoun trauma previo. La razón de porqué estos cambios son más prominentes en determinados enfermos y no en otros, que padecen también la mismaenfermedad, sigue sin conocerse en la actualidad (AU)


TLipo-membranous panniculitis or membrano-cystic steatonecrosis is an alteration of the adipose tissue. Sclerotic plaques with tendency to becomechronic, do usually appear located on the lower area of the legs. It is almost exclusive in female mostly obese and diabetic and with a severe componentof venous stasis. It has the histologic features of a lobule panniculitis, cystic cavities surrounded by fatty tissue with clear signs of steatonecrosisare formed by confluence. We present the case of a 36 years old female who developed a painful lesion on the location of a previous lesion, it hadnumerous nodule-cystic formations we noticed on palpation. The dermato-pathological study showed up the presence of cystic structures located onthe lobules and at the level of the septum, surrounded by fatty tissue, with clear signs of steatonecrosis, a significant presence of frothy histiocytes andbreakage of the cellular membranes with formation of micro-cysts. The cystic cavities were limited in their inner side by a serpiginous membrane, nonuclear, homogeneous and eosinophilic, PAS+, with a granulated appearance. It even formed in some areas pseudo-papillae, which projected themselvestowards the interior of the cyst. It has been suggested that ischemia is the main pathogenic cause for lipo-membranous panniculitis, althoughother reasons are also considered such as a previous trauma. Nowadays, we do not still know the reason why these changes are more prominent incertain patients than in other with the same disease (AU)

RESUMO

Los angiosarcomas son neoplasias malignas poco frecuentes que se originan a partir del endotelio de los vasos sanguíneos. Pueden aparecer en la piely en órganos internos como hígado, mama, bazo o corazón. Presentamos dos casos de angiosarcoma cutáneo con clínica y evolución bien diferentes.El primer caso se trata de un varón de 65 años que consultó por presentar en dorso nasal una placa violácea e infiltrada a la palpación de 7 meses deevolución. El estudio dermatopatológico mostró una proliferación de vasos irregulares, disecantes y anastomosados que infiltraba el músculo esqueléticosubyacente. A mayor detalle, se apreciaban células endoteliales atípicas, con núcleos grandes e hipercromáticos y abundantes mitosis. Las célulastumorales fueron positivas para CD31. El tratamiento consistió en extirpación amplia de la lesión, reparación mediante colgajo glabelar y radioterapiade la zona intervenida. Tras más de un año de seguimiento no se han apreciado signos de persistencia.El otro caso es el de una mujer de 78 años con una tumoración ulcerada de gran tamaño de localización fronto-parietal izquierda. A la exploración presentabauna masa excrecente, ulcerada, friable, con focos de necrosis y evidentes signos de proliferación tumoral. El estudio dermatopatológico fueanálogo al caso anterior. Dado el gran desarrollo del tumor y no siendo factible su extirpación, se remitió al Servicio de Oncología para tratamientopaliativo con quimioterapia. Sin embargo, en este caso sólo se ha conseguido un enlentecimiento de la progresión tumoral, pero no se consiguió detenerla evolución y terminó en exitus (AU)


Angiosarcomas are rare malignant neoplasms originated from the endothelial cells of blood vessels. They can arise either on skin or in internal organssuch as liver, breast, spleen or heart. Two cases of cutaneous angiosarcoma with different clinical and evolution are reported.The first case is a 65 years old male with a violaceous plaque on the nasal dorsum, infiltrate to palpation and with a 7 months evolution . The dermatopathologicalstudy showed a proliferation of irregular dissecting and anastomosed vessels, that infiltrated the underlying skeletal muscle. Atypicalendothelial cells with big and hyperchromatic nucleus and abundant mitosis could be observed in great detail. Tumour cells were positive to CD31.The treatment consisted on a wide removal of the lesion, repairing with glabella flap and radiotherapy on the intervened area. After a year long followup, no persistence was observed.The other case was a 78 years old female with a big ulcerated tumour located on the left frontoparietal area. It presented an excrescent mass, ulcerated,friable, with points of necrosis and clear signs of tumour proliferation. The dermato-pathological study was analogous to the case above. The bigsize of the tumour made it not suitable for removal, therefore we sent the case to the Oncology Service to receive palliative treatment with chemotherapy.However, we could only achieve the slow down of the tumour progress, but finally the patient dead (AU)

RESUMO

We report a case of a 15-year-old boy with hyperkeratotic lesions that were linear or striated on the palms and nummular on the soles. He was the only family member known to be affected, suggesting that the condition could be attributed to a de novo mutation or the recessive form of keratoderma palmoplantaris striata, described by Degos as chronic idiopathic acrokeratosis. The lesions did not improve with topical treatments (keratolytic agents, emollients, or corticosteroids) or oral retinoids. We observed that scratching of the affected areas was the main reason for deterioration of the lesions.

RESUMO

INTRODUCTION: Hidradenitis suppurativa is a chronic inflammatory disease characterized by significant morbidity. Current medical therapies are usually only minimally effective. OBJECTIVE: To assess the efficacy and safety of infliximab monotherapy for the treatment of severe extensive refractory forms of hidradenitis suppurativa. DESIGN: A retrospective study in a group of 6 patients who received treatment with infliximab for hidradenitis suppurativa, in the Dermatology Department of the University Hospital of Puerto Real in the last year. The dose was 5-10 mg/kg at weeks 0, 2 and 6, followed by a maintenance dose every 4 weeks. Subjective and objective efficacy was assessed before and after each treatment session. RESULTS: All patients experienced improvement in subjective symptoms after the initial dose. A decrease in exudation, the size and number of lesions and less development of fistulous tracts were observed. The patients were followed up during 6 months. Treatment was generally well tolerated and there was only one mild reaction to the infusion in the form of headache. No patient required treatment discontinuation due to adverse effects. CONCLUSIONS: Infliximab was shown to be an effective therapeutic alternative for severe extensive forms of hidradenitis suppurativa when it is used as monotherapy.

RESUMO

La papilomatosis oral florida puede evolucionar hacia un carcinoma verrucoso de mucosa oral, que aparece en personas mayores y relacionado con la infección por el virus del papiloma humano. Se caracteriza por lesiones de curso crónico, vegetantes o verrucosas, rosadas y que a veces están cubiertas de una pseudomembrana amarillenta. Caso clínico: Presentamos el caso clínico de una paciente mujer de 65 años que presentaba desde hacía más de 3 años lesiones ulcerativas y verrucosas que afectaban a todo el paladar duro, asociado a la pérdida reciente de dos molares. En otras zonas de la cavidad oral las lesiones eran verrucosas rosadas y cubiertas de una membrana pseudoamarillenta. La realización de una TAC confirmó la destrucción del suelo del seno maxilar con penetración de un proceso expansivo que en el estudio histológico se confirmó como carcinoma epidermoide infiltrante, secundario a papilomatosis oral florida. Conclusión: Las infecciones mucosas por VPH son enfermedades con un claro potencial de malignización, por lo que deben ser vigiladas muy estrechamente, estando indicado un tratamiento que vaya encaminado a la resolución completa del cuadro en tanto en cuanto la evolución del proceso y el estado clínico del paciente lo permita. El tratamiento precoz es de gran utilidad


The oral florid papillomatosis can evolve into a verrucous carcinoma of oral mucosa, that appears in older people and related with the infection due to human papilloma virus. Its characteristics are chronic lesions, vegetating or verrucous, of a pink color and which are sometimes covered with a yellowish pseudo-membrane. Clinical case: A 65-year-old female patient that presented verrucous and ulcerative lesions for more than 3 years that affected all the hard palate, associated with the recent loss of two molars is reported. In other areas of the oral cavity the lesions were pink, verrucous, and covered with a yellowish- like membrane. The practice of a CT confirmed the destruction of the floor of the maxillary sinus with penetration of an expansive process that in the histologic study was confirmed as infiltrating epidermoid carcinoma, secondary to oral florid papillomatosis. Conclusion: The mucous infections by HPV are illnesses with a clear potential of malignancy, reason why a close eye should be kept on them, a treatment being indicated that directs toward the complete resolution of the clinical pattern as long as the evolution of the process and the clinical condition of the patient permit it

RESUMO

INTRODUCTION: Allergic contact dermatitis (ACD) is equally as likely in infancy as in adulthood, and represents 20% of all cases of dermatitis in children. Its true prevalence and incidence are, however, unknown. MATERIALS AND METHODS: We have conducted a retrospective study over 10 years of a group of patients aged 15 years or less, with clinical suspicion of ACD. Patch tests were performed in accordance with the standards of the GEIDC. RESULTS: The study covered 96 patients with a mean age of 10.57+/-0.67 years. The zones most frequently affected by eczemas were those of diffuse distribution (28% of patients) and of the hands (27%). We found at least one positive response in 52% of the cases. The most frequent allergens were thiomersal (21%), mercury (19%) and nickel (18%). We have found a statistically significant association between age of less than 15 years and positive response to thiomersal [P<0.01; OR: 8.5 with confidence interval (CI) 95%: 5.08

RESUMO

Rhinoscleroma is a chronic, granulomatous infectious disease that responds poorly to treatment. In recent years an increasing number of cases have been reported in nonendemic areas, explained largely by major migratory movements. We describe rhinoscleroma in three siblings. They had ulcerated but painless lesions, which bled spontaneously, and hemorrhagic scabs or crusts in their noses. In one child, the lesions had destroyed the entire left nasal ala and alar cartilage and most of the right. Dermatopathologic study identified the Mikulicz macrophages that contained organisms. It is possible that disposing factors could have been the neutropenia common to the three children and their poor living conditions. They were treated with a combination of trimethoprim-sulfamethoxazole and cefalexin, for a period of 3 months. We present this unusual case history of three siblings affected by a process that is relatively infrequent in our area of practice and is not considered very contagious. It is important to recognize the clinical signs characteristic of this disease, the diagnosis of which is not easy. Improvements in living conditions, hygiene, and health standards are essential prerequisites for its control and prevention.

RESUMO

Durante el período comprendido entre marzo de 1997 y marzo de 2002 hemos atendido un total de 3.296 consultas urgentes, lo que representa una incidencia de 239,7/100.000 habitantes. Esa cifra corresponde al 1,20 por ciento de las urgencias médicas hospitalarias. De los pacientes atendidos, 42 necesitaron ingreso urgente, lo que supuso el 20,5 por ciento de los ingresos de nuestro Servicio. La urticaria aguda, la dermatitis atópica y el prurigo han sido las tres enfermedades más prevalentes, constituyendo el 19,86 por ciento de toda la patología asistida. De forma individual, la urticaria aguda es el diagnóstico que se realizó con mayor frecuencia (7,76 por ciento). La oferta de asistencia especializada urgente en Dermatología presenta las ventajas de ofrecer un nuevo servicio a los usuarios de la sanidad pública, un servicio de derivación a los médicos de Atención Primaria, lo que aumentaría el número de consultas, mejoraría la relación entre primeras consultas y consultas sucesivas y posibilitaría una mejor docencia de los residentes que verían e ingresarían pacientes que, de otra forma, irían a otros centros o a otras especialidades (AU)

RESUMO

Varón de 16 años que consultó por presentar una erupción cutánea de aparición brusca, constituida por lesiones con morfología típica de diana o escarapela de Bateman, cuyo estudio dermatopatológico confirmó el diagnóstico de eritema exudativo multiforme (EEM). Tras una exploración detenida se observó que además presentaba en el tercerdedo de la mano derecha una lesión de aspecto diferente, que al estudio dermatopatológico permitió observar algunas células con núcleo y citoplasma modificados que sugerían inclusiones virales, todo ello compatible con nódulo de Orf. La causa más frecuente de EEM es el virus del herpes simples, seguida de mycoplasma pneumoniae y de algunos fármacos, pero su asociación con parapoxvirus es excepcional y sólo se han recogido algo más de 20 casos en la literatura de nódulos Orf asociados a EEM, que se caracteriza por comencar de 10 a 14 días después de aparecer el nódulo de Orf y desaparecen en el plazo de una semana y media, aunque en nuestro caso las lesiones de EEM se iniciaron a las 48 horas de comenzar el Orf. En España no tenemos información de que se haya observado ningún caso de esta asociación, aunque sí se han descrito varios casos asociados a nódulos de los ordeñadores. En definitiva, se trata de un caso de nódulo de Orf adquirido a través del contacto con un animal enfermo, que posteriormente desarrolló un EEM y aunque los parapoxvirus pueden ser una causa poco frecuente de EEM, el nódulo de Orf debe ser tenido en cuenta en el diagnóstico etiológico del EEM en poblaciones de riesgo (AU)
