Abstract

Under the right conditions, dermoscopy allows us to observe the vascular features of many different types of skin lesions. The visualization and identification of vessels with a characteristic morphology can be the key to diagnosis, especially in hypopigmented lesions in which the typical pigmented structures are not visible.

Some of the more characteristic associations are the presence of crown vessels in sebaceous hyperplasia, arborizing telangiectasias in basal cell carcinoma, comma-shaped vessels in intradermal and compound nevi, dotted vessels in Spitz nevi and melanoma, and hairpin vessels in seborrheic keratoses.

The recognition of distinctive vascular features can be of great help in the diagnosis of many types of skin lesions, and very often such patterns are the only key to the diagnosis of melanoma.

Resumen

La dermatoscopia permite observar, en las condiciones adecuadas, la vascularización presente en las lesiones cutáneas de muy diversa índole. La visualización e identificación de vasos de morfología característica puede ser la clave en el diagnóstico de determinadas lesiones, especialmente en el caso de aquellas hipopigmentadas, en las que no es posible identificar las estructuras pigmentadas clásicas.

Así pues, algunas de las asociaciones más características son la presencia de vasos «en corona» en la hiperplasia sebácea, las «telangiectasias arboriformes» en el carcinoma basocelular, los vasos «en coma» en los nevos intradérmicos y compuestos, los vasos «en cabeza de alfiler» en los nevos de Spitz o melanoma, o los vasos «en horquilla» en las queratosis seborreicas.

El reconocimiento de estructuras vasculares distintivas puede ser de gran ayuda para el diagnóstico de numerosas lesiones. A menudo, constituyen la única clave para el diagnóstico del melanoma.
