C44.32

Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. History of sunburns, especially during childhood. Having fair skin, light hair, and light eye color. Chronic skin injuries or wounds that do not heal. Immunosuppression, such as in organ transplant recipients or individuals with immune-compromising conditions. Exposure to certain chemicals or carcinogens. Previous history of skin cancer or precancerous skin lesions.

Key Symptoms: A persistent, raised, and scaly patch or bump that may be crusted or ulcerated. A sore or wound that does not heal or keeps returning. A firm nodule or growth that gradually enlarges. Changes in the appearance of existing moles or skin spots. Tenderness or pain around the affected area, especially if the tumor invades nerves or tissues. Occasional bleeding or oozing from the lesion.

Diagnosis Path: Diagnosis primarily involves a physical examination of the skin and detailed patient history. Confirmatory evaluation includes a skin biopsy, where a small tissue sample is taken from the suspicious lesion and examined under a microscope. Additional imaging studies may be employed if there is concern about local invasion or metastasis, such as ultrasound, MRI, or CT scans. Early detection and precise staging are essential for optimal management.

Treatment Protocols: Treatment options depend on the size, location, and extent of the cancer, as well as the patient’s overall health. Common approaches include: - Surgical excision: Removing the tumor with clear margins to ensure complete removal. - Mohs micrographic surgery: A precise surgical technique that removes the cancer layer by layer to conserve healthy tissue. - Cryotherapy: Using extreme cold to destroy cancerous cells, suitable for small lesions. - Radiation therapy: Employing focused radiation to eradicate cancer cells, especially in cases where surgery isn't feasible. - Topical medications: Such as 5-fluorouracil or imiquimod creams, primarily for superficial lesions. - Systemic therapies: Including targeted therapies or immunotherapy in advanced or metastatic cases. Follow-up care involves regular skin examinations to monitor for recurrence or new skin cancers, as individuals with one skin cancer are at increased risk for others.
