Squamous cell carcinoma

Squamous cell carcinoma (Squamous cell carcinoma) is short for squamous cell carcinoma. It originates in the skin epidermis and its appendages (hair follicle funnel, sebaceous duct, terminal sweat duct). Keratinocytes occur in exposed parts of the scalp, face, neck and back of hands. It can show ulcers at an early stage, and is often secondary to chronic ulcers or chronic sinus openings, or the ulcers in the scar area will not heal and become cancerous. Clinically, it can be cauliflower-shaped, with irregularly raised edges, uneven bottoms, and easy bleeding, often accompanied by infections that cause stench. May have local infiltration and regional lymph node metastasis. In the lower limbs are often accompanied by osteomyelitis or periostitis.
