Nombres alternativos

Hemangioma aracniforme

Definición:

Es una acumulación anormal de vasos sanguíneos cerca de la superficie de la piel.

Causas, incidencia y factores de riesgo:

Los angiomas aracniformes son muy comunes y predominan especialmente durante el embarazo y en pacientes con enfermedad hepática. Se presentan tanto en niños como en adultos.

Síntomas:

  • Úlcera (lesión) vascular que:
    • puede tener un punto rojo en el centro.
    • presenta extensiones rojizas que se irradian desde el centro.
    • desaparece con la presión y reaparece al liberar la presión.
  • Se observa con más frecuencia en la cara y en el tronco.

Signos y exámenes:

Por lo general, no es necesario realizar ningún examen, pero se puede requerir una biopsia de piel para confirmar el diagnóstico en algunos casos. Asimismo, se pueden hacer exámenes de sangre si se sospecha un problema hepático.

Tratamiento:

El tratamiento generalmente no es necesario. En algunos casos, se utiliza la electrocauterización o un tratamiento con láser.

Expectativas (pronóstico):

Los angiomas aracniformes con frecuencia desaparecen en los niños, pero tienden a persistir en los adultos.

Situaciones que requieren asistencia médica:

Un angioma aracniforme generalmente se puede examinar durante una visita al médico de rutina. Es importante que le comente al doctor si desarrolla un angioma aracniforme nuevo para descartar afecciones médicas conexas.
