We report the case of a girl with hypertrichosis lanuginosa congenita treated with diode laser depilation since the age of 9 months. The treatment was well tolerated, and neither general nor local anesthesia was needed. A reduction of approximately 80% of facial and body hair was noted, which improved her condition significantly.

Caso clínico REVISIÓN DE LA LITERATURAEl síndrome de Gianotti-Crosti (Sx G-C), también conocido como acropapulosis de la infancia o acrodermatitis papular infantil, fue descrito por primera vez por Gianotti en 1955. Es una dermatosis relativamente común y autolimitada 1 que afecta a niños sin distinción de género, desde los seis meses hasta los 12 años de edad, con un pico de mayor incidencia entre el primero y el sexto año de vida. 2 Se han publicado casos en jóvenes y adultos, siendo las mujeres más afectadas en este último grupo. 3,4 Este padecimiento se encuentra subdiagnosticado, por lo que se desconoce su prevalencia exacta.El Sx G-C surge como un patrón de reacción cutánea, secundario a infección por virus, bacterias y vacunas. Se presenta varias semanas posteriores a la resolución de estas infecciones. 2 Los virus más frecuentemente involucrados son: hepatitis B (VHB) variedad a y w, Síndrome de Gianotti-Crosti o acrodermatitis papular de la infancia Gianotti-Crosti syndrome or childhood papular acrodermatitis

Background: Atopic dermatitis is observed in up to 20% of children, hence the importance of tools to support its evaluation. Objective: To determine the validity and reliability of the Spanish adaptation of the IDQOL questionnaire in patients <4 years of age with atopic dermatitis (AD). Methods: Translation and back-translation of the questionnaire; a pilot test was done in 30 children with AD to arrive at a final version. Internal reliability (Cronbach's alpha) and correlation of IDQOL and SCORAD scores (Pearson correlation coefficient) were measured. Results: 102 children aged between two and 48 months were included. The Pearson correlation coefficient (r) of IDQOL and SCORAD scores was 0.697 (p = 0.0001), indicating a high positive correlation. The correlation between the severity measured by the caregiver and the SCORAD score (r = 0.565, p = 0.0001) proved to be low positive. The internal consistency of IDQOL using Cronbach's alpha was 0.84, indicating good consistency of the instrument for assessing quality of life. Conclusion:The IDQOL questionnaire in Spanish is a valid measure of quality of life in patients < 4 years with AD and is useful in monitoring and in clinical trials.
