Abstract
A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. The apertures in the periphery may be larger than the apertures in the central portion. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed.

- an adhesive configured to extend through the apertures in at least the periphery of the base layer to contact tissue surrounding the tissue site, at least one of the apertures in a corner of the periphery of the base layer being configured to expose more of the adhesive for contact with the tissue than other apertures in the periphery of the base layer;
- a sealing member having a periphery and a central portion, the periphery of the sealing member positioned proximate to the periphery of the base layer, wherein the central portion of the sealing member and the central portion of the base layer define an enclosure;
