Subcutaneous tissue of abdomen

The subcutaneous tissue of the abdomen (also known as the superficial fascia of the abdomen) is the layer of connective tissue and adipose (fat) tissue located between the skin (dermis) and the deep fascia overlying the abdominal wall musculature. It is composed of two distinct layers:

Fatty layer of abdominal subcutaneous tissue (Camper's fascia) — the superficial layer, which is primarily fatty and varies in thickness depending on body habitus. It is continuous with the superficial fascia of adjacent regions (thigh, perineum, thorax).

Membranous layer of abdominal subcutaneous tissue (Scarpa's fascia )— the deeper, more membranous layer composed of elastic and collagen fibers with less adipose tissue. Scarpa's fascia is clinically significant because:

• It is continuous inferiorly with the dartos fascia of the scrotum (or labia majora) and with Colles' fascia in the perineum.

• It serves as a potential anatomical barrier that can contain or direct the spread of fluid collections (e.g., urine extravasation, hematomas, or abscesses).
