RESUMO
La dermatoscopia ha aumentado la precisión en el diagnóstico clínico de lesiones cutáneas complejas. Es una herramienta que permite identificar pequeñas áreas de sospecha, no apreciables a simple vista y que requieren examen histopatológico específico. El derm dotting es un método de marcaje selectivo de zonas de interés para asegurar que estos focos son estudiados microscópicamente, puesto que por su pequeño tamaño podrían no aparecer en las secciones de rutina o ser difíciles de correlacionar con la imagen dermatoscópica. Combina la dermatoscopia in vivo o ex vivo con la aplicación de esmalte ungueal. A diferencia de los colorantes usuales, el uso de esmalte ungueal no altera la histología. Puede ser aplicado por parte del dermatólogo o durante el procesamiento macroscópico en el laboratorio. El derm dotting es una técnica novedosa, sencilla y económica, que puede implementarse rápidamente en cualquier Laboratorio de Dermatopatología. Mejora la precisión diagnóstica ya que traslada los hallazgos dermatoscópicos al estudio histológico
Dermoscopy has improved diagnostic precision in the clinical evaluation of complex skin lesions by helping to pinpoint small clinically suspicious areas that are not visible to the naked eye but require histopathologic examination. Derm dotting is a new technique for selectively marking areas of interest to ensure they are examined under a microscope. Left unmarked, suspicious areas might not appear in routinely prepared cross sections or might be difficult to correlate with dermoscopic images. In vivo or ex vivo derm dotting involves the application of nail polish, which, unlike stains, leaves tissues unaltered. Dots can be placed by the dermatologist or laboratory staff during macroscopic preparation of the sample. Derm dotting is a simple, inexpensive technique that any dermatopathology laboratory can quickly adopt to improve diagnostic precision through better dermoscopic-histologic correlation
