Skin squamous cell carcinoma, as the name implies, is closely connected to the squamous cells of the skin. These cells are usually located in the outermost layer of our skin - the epidermis, and they protect our bodies like armor. But when these cells undergo abnormal proliferation and grow out of control, skin squamous cell carcinoma is formed. This name intuitively reveals its origin and characteristics.
Squamous cell carcinoma can occur all over the body, such as the skin of the head, face, trunk, and limbs, and can also occur in the oral and vulvar mucosa. It is mostly manifested as a new growth of the skin/mucosa, which grows significantly and quickly, protrudes from the skin, is hemispherical, has a ruddy surface, may have ulcers in the center or bleed easily when touched, and the surface of the bleeding and ulcerated rash will be covered with scabs, and the edge will feel "rooted" (infiltrated) when touched. Generally, there is no feeling of itching or pain. If infection occurs, pain and suppuration will occur.
