C44.721

Clinical Causes: Chronic exposure to ultraviolet (UV) radiation from the sun or tanning beds Repeated skin injuries or irritation in a specific area Long-term presence of scars or chronic sores Exposure to certain chemicals or carcinogens Weakened immune system, including conditions like HIV/AIDS or use of immunosuppressive drugs Older age, as the risk increases with age Fair skin, which provides less natural protection against UV rays

Key Symptoms: A persistent, raised, or crusted lesion on the skin that may be ulcerated A sore that does not heal or keeps coming back A raised growth with a rough, scaly surface A red, sore area that may bleed or develop into an ulcer Changes in skin texture or color in the affected area In some cases, pain or tenderness in the lesion

Diagnosis Path: Diagnosis typically involves a physical examination of the affected area, followed by a skin biopsy to confirm the presence of squamous cell carcinoma. Imaging tests, such as X-rays or MRI, may be employed if the doctor suspects the cancer has spread beyond the skin to nearby tissues or lymph nodes. It's essential to differentiate SCC from other skin conditions to determine the appropriate course of action.

Treatment Protocols: Treatment options usually depend on the size, location, and severity of the lesion, as well as whether the cancer has spread. Common approaches include: - Surgical excision to remove the cancerous tissue - Mohs surgery, which involves removing the cancer layer by layer to preserve healthy tissue - Curettage and electrodessication, especially for smaller lesions - Radiation therapy, in cases where surgery isn't suitable or to target residual cancer cells - Topical treatments like chemotherapy creams for superficial lesions - Follow-up care to monitor for recurrence or new skin cancers Early diagnosis and treatment are important for favorable outcomes, so seeking medical assessment for suspicious skin changes is advised.
