Sangrado dentro de la piel - Overview

Nombres alternativos

Equimosis o hematomas; Manchas rojas en piel; Pequeñas manchas rojas en la piel; Petequias

Definición:

El sangrado por debajo de la piel puede ocurrir a partir de vasos sanguíneos rotos que forman diminutos puntos rojos, llamados petequias. La sangre también se puede acumular bajo el tejido en áreas planas más grandes, llamadas púrpura o en un área con hematomas grandes, llamada equimosis.

Consideraciones:

Aparte del hematoma o moretón común, el sangrado dentro de la piel o las membranas mucosas es una señal muy significativa y siempre lo debe revisar un médico.

El enrojecimiento de la piel (eritema) no debe confundirse con un sangrado. Las áreas de sangrado bajo la piel no se vuelven pálidas (blanquear) cuando se presiona allí. El enrojecimiento del eritema disminuye cuando se le aplica presión y retorna cuando ésta se libera.
