High-frequency ultrasound features in a case of gouty panniculitis.

Gouty panniculitis is caused by the deposition of urate crystals in the subcutaneous tissue, accompanied by a lobular panniculitis. It presents as subcutaneous nodules, most commonly located on the lower extremities. Being an unusual clinical presentation of gout, the sonographic findings of gouty panniculitis have been scarcely described in the literature. Our report describes the ultrasound features we found in a case of gouty panniculitis and the usefulness of this technique for diagnosis and monitoring of this disease.

Nevo de Meyerson / Meyerson naevus

Con el nombre de nevo de Meyerson se reconoce clásicamente al nevo que experimenta una reacción inflamatoria local eccematosa, muchas veces persistente a pesar del tratamiento con corticoides tópicos. Se trata de un fenómeno descrito sobre todo en lesiones melanocíticas, aunque también se han publicado casos en lesiones no melanocíticas (queratosis seborreicas, nevos sebáceos, lesiones vasculares...). Se presenta el caso de un niño de 11 meses de edad con una lesión congénita facial, que experimentó una reacción inflamatoria local, con estudio dermatoscópico dudoso, y cuyo resultado histológico en la extirpación fue concordante con un nevo de Meyerson(AU)

Meyerson phenomenon is known as an inflammatory, eczematous, local reaction, surrounding a melanocytic nevi, in many cases persitent even if treated with topical steroids. It is described not only in melanocytic lesions but also in non melanocytic, such as seborrheic keratosis, sebaceus nevi or vascular lesions. We present the case of a 11 months old boy who had a congenital lesion on his face that began with a local inflammatory reaction, with atypical dermoscopic image, and with a histological study concordant with Meyerson naevus(AU)

Arrugamiento acuagénico palmar en unniño con fibrosis quística / Aquagenic wrinkling of the palmas in a young boy with cystic fibrosis

El arrugamiento acuagénico es una afección cutánea descrita en la última década. Se considera poco frecuente, característico de mujeres jóvenes eidiopático; aunque en al menos tres enfermos se ha relacionado con la toma de antiinflamatorios inhibidores selectivos de la ciclooxigenasa-2. Recientementese ha recuperado su vinculación, realizada hace más de 30 años, con la fibrosis quística, y se ha referido en tres pacientes con dicha enfermedad.Describimos un nuevo caso en un niño de 5 años con fibrosis quística, documentada con estudio genético. Discutimos su eventual consideracióncomo marcador cutáneo de la fibrosis quística (AU)

Aquagenic wrinkling is a cutaneous condition described in the last decade. It is considered to be uncommon, typical in young females and idiopathic;although it has been related with selective inhibitor of cyclooxygenasa-2 anti-inflammatory medication intake in at least three patients. Recently itsrelationship with cystic fibrosis, recognised more than 30 years earlier, has been recovered and three patients have been reported in with that disease.A new genetically documented cystic fibrosis case in a 5 year old boy is described. The eventual consideration of this condition as a cystic fibrosis cutaneousmarker is discussed (AU)

[Leishmania braziliensis: report of a pediatric imported case with response to liposomal amphotericin B]. / Leishmania braziliensis: descripción de un caso pediátrico importado con respuesta a anfotericina B liposomal.

Leishmania braziliensis is the main etiologic agent of leishmaniasis in South America. A 9-year-old boy consulted for the presence of round, ulcerative lesions with raised borders that were painful and have appeared after a travel to Bolivia and Brazil. The culture for parasites showed leishmanias and the PCR was positive for L. braziliensis. The patient underwent treatment with itraconazol but due to the persistence of lesions he received liposomal amphotericin B with complete resolution of the lesions. In all lesions by L. braziliensis the treatment must be systemic due to the risk of mucosal dissemination. Liposomal amphotericin B is a convenient alternative to pentavalent antimonials given its efficacy and good tolerance.

Larva migrans cutánea: lesiones múltiples tras viaje a Brasil / Cutaneous larva migrans: multiple injuries after a trip to Brazil

La larva migrans cutánea es un proceso secundario a la penetración en la piel de una larva de nematodo que se desplaza por la epidermis. Es típico de zonas tropicales. Su presentación clínica se caracteriza por unos trayectos lineales tortuosos, habitualmente pruriginosos, que se localizan con mayor frecuencia en los pies, aunque pueden aparecer en otras localizaciones. Aunque es un proceso autolimitado suele requerir tratamiento por el intenso prurito que produce y las posibles complicaciones asociadas, principalmente la sobreinfección bacteriana. Presentamos un caso de un paciente con varias lesiones de larva migrans cutánea después de realizar un viaje a Brasil

Cutaneous larva migrans is an eruption caused by a nematode larva that penetrates the skin and moves through the epidermis. It is typical of tropical areas. Its clinical presentation is characterized by linear pruritic lesions that are usually serpiginous. This is most often located on the feet, although it may appear in other locations. Although it is a self-limited condition, it generally requires treatment due to the intense itching it produces and the possible associated complications, mainly secondary bacterial infection. We present a case of a male patient with several cutaneous larva migrans lesions after having traveled to Brazil

Leishmania braziliensis: descripción de un caso pediátrico importado con respuesta a anfotericina B liposomal / Leishmania braziliensis: report of a pediatricimported case with response to liposomalamphotericin B

Leishmania braziliensis es el principal agente etiológico de leishmaniasis cutánea en América del Sur. Un varón de 9 años consultó por lesiones redondeadas ulceradas de bordes sobreelevados, que eran dolorosas y habían aparecido después de un viaje por Bolivia y Brasil. En el cultivo de parásitos se objetivaron Leishmanias y la reacción en cadena de la polimerasa (PCR) para L. braziliensis fue positiva. El paciente realizó tratamiento con itraconazol, y por persistencia de las lesiones inició anfotericina B liposomal con resolución completa de las mismas. En toda lesión por L. braziliensis el tratamiento debe ser sistémico por el riesgo de diseminación mucosa. La anfotericina B liposomal es una buena alternativa a los antimoniales pentavalentes por su eficacia y buena tolerancia

[Acrocyanosis as a form of presentation of progressive systemic sclerosis]. / Acrocianosis como forma de debut de una esclerosis sistémica progresiva.

Acrocyanosis is an infrequent entity characterized by persistent and symmetrical erythrocyanotic discoloration of the hands, feet and face, which is not preceded by episodes of previous paleness. Acrocyanosis can be secondary to a variety of underlying causes, but is uncommon as a form of presentation of systemic sclerosis. We present a new clinical case of this disease and discuss its etiopathogenic, clinical, diagnostic and therapeutic characteristics; in addition to, we seek to distinguish this term from others that might be confused in the literature.

Acrocianosis como forma de debut de una esclerosis sistémica progresiva / Acrocyanosis as a form of presentation of systemic sclerosis

La acrocianosis es un cuadro clínico caracterizado por una coloración azul violácea persistente y simétrica de zonas acras, principalmente manos y pies, que no está precedida por episodios de palidez previos. Es una entidad que puede asociarse a diversas causas subyacentes, pero es infrecuente que lo haga como forma de debút de una esclerosis sistémica progresiva. Se presenta a continuación un nuevo caso de esta patología y se comentan sus características etiopatogénicas, clínicas y diagnósticas más relevantes además de un intento de diferenciar este término de otros con los que existe confusión en la literatura
