These tumors may appear as nodules or as red, scaly patches. Squamous cell carcinoma is the second most common skin cancer found in Caucasians. It typically is found on the rim of the ear, the face, the lips and mouth. It is rarely found on dark-skinned persons. This cancer will develop into large masses.
The branches of the femoral nerve serve the quadriceps muscles and skin of the anterior and medial thigh, while its largest branch, the saphenous nerve, extends to the skin of the medial leg and foot.
This serves the same function as the psoas major muscle. It flexes the thigh at the hip joint. It's innervated by the femoral nerve. You can see how both the distal ends of the iliacus and psoas major pass underneath this ligament, the inguinal ligament to insert onto the lesser trochanter of the femur.
