Urticaria multiforme: A report of 5 cases and a review of the literature.

Urticaria multiforme is a cutaneous disorder that affects infants and small children. It is characterized by large, annular urticarial plaques with a violaceous center and is frequently accompanied by fever. Urticaria multiforme follows a benign, self-limiting course, but the striking appearance of the lesions can cause alarm and considerable anxiety among parents. We present 5 cases of urticaria multiforme seen in our hospital over a period of 18 months. All the cases were preceded by an infection of the upper airways or otitis, and they were all empirically with amoxicillin. It is important to be familiar with this condition to reassure parents and avoid unnecessary hospital admissions and tests.

New Mutation in the Birt Hogg Dube Gene. / Nueva mutación en el síndrome de Birt Hogg Dubé.

Patients with Birt-Hogg-Dube syndrome have an increased risk of developing hamartomas of the pilosebaceous unit, renal tumors of various types, lung cysts, and spontaneous pneumothorax. We present the case of a 54-year-old woman with a long history of whitish papules in the central region of the face and a family history of similar lesions. Biopsy and genetic study revealed a new mutation of the gene involved in Birt-Hogg-Dube syndrome.

Cinco casos de urticaria multiforme y revisión de la literatura / Urticaria multiforme: A report of 5 cases and a review of the literature

La urticaria multiforme es un cuadro cutáneo, propio de lactantes y niños pequeños, caracterizado por la aparición de grandes placas anulares urticariformes de centro violáceo frecuentemente asociado a un proceso febril. Tiene un curso benigno y autolimitado, pero el llamativo aspecto de las lesiones puede ser alarmante y generar gran ansiedad en los padres. Presentamos 5 casos de urticaria multiforme vistos en nuestro hospital a lo largo de 18 meses. El antecedente común a todos ellos fue una infección de vías respiratorias altas u otitis por la que fueron tratados empíricamente con amoxicilina. Es importante saber reconocer esta entidad para tranquilizar a los padres, ahorrar el ingreso hospitalario y evitar la realización de pruebas diagnósticas innecesarias

Nueva mutación en el síndrome de Birt Hogg Dubé / New Mutation in the Birt Hogg Dube Gene

El Birt Hogg Dubé es un síndrome que predispone a la aparición de hamartomas del folículo pilosebáceo y a mayor riesgo de presentar tumores renales de diversa extirpe, quistes pulmonares y neumotórax espontáneos. Presentamos el caso de una mujer de 54 años que presenta desde hace años pápulas blanquecinas centrofaciales e historia familiar de esas mismas pápulas. Tras biopsia y estudio genético de la paciente se detecta una nueva mutación en el gen implicado en este síndrome (AU)
