The Scarpa fascia is a membranous layer of the anterior abdominal wall. The following distinct layers are identified traversing the abdominal wall from superficial to deep: skin, subcutaneous tissue, superficial fascia, external oblique muscle, internal oblique muscle, transversus abdominis muscle, transversalis fascia, preperitoneal adipose tissue, and peritoneum. The superficial fascia consists of 2 components: a membranous layer, the Scarpa fascia, and an outer fatty layer known as the Camper fascia (see Image. Fascial Layers). The Scarpa fascia lies deep to the Camper fascia and superficial to the external oblique muscle. Lateral attachment occurs at the aponeurosis of the external oblique muscle. Medial continuity is present with the linea alba and pubic symphysis. In the upper thigh, fusion occurs with the fascia lata approximately 1 fingerbreadth inferior to the inguinal ligament. The term “Scarpa fascia” is based on the anatomic region of distribution. The Scarpa fascia extends over the spermatic cord and into the scrotum, where the layer is termed "dartos fascia." From the scrotum, the fascia may be traced posteriorly as it continues as Colles fascia while blending with the deeper layers of the perineum. In female individuals, extension occurs into the labia majora. The Scarpa fascia is a clinically important structure due to its role in abdominal incision repair and in the formation of fascial planes that limit the extravasation of bodily fluids.
