C44.799

Clinical Causes: Exposure to ultraviolet (UV) radiation from the sun or tanning beds Prolonged exposure to certain chemicals or substances that may increase skin cancer risk History of previous skin cancer or other skin diseases Immune system suppression, such as in organ transplant recipients or those with HIV/AIDS Genetic predispositions to skin cancer Chronic skin injuries or scars that may become malignant over time

Key Symptoms: A persistent sore or ulcer that doesn't heal New growth, bump, or sore on the skin that enlarges over time A change in the appearance of an existing mole or skin lesion Color changes, such as uneven pigmentation or areas of redness Raised, firm, or crusted patches on the skin Bleeding or oozing from a skin lesion Skin pain or sensitivity in the affected area

Diagnosis Path: Diagnosis of this skin cancer involves a combination of physical examination and diagnostic tests. The healthcare provider will examine the lesion and assess its characteristics. A biopsy is essential to confirm malignancy, where a small tissue sample from the lesion is removed and examined under a microscope. Additional imaging tests might be used to determine the extent or spread of the cancer, such as ultrasound, MRI, or CT scans. Early detection and accurate diagnosis are crucial for effective treatment planning.

Treatment Protocols: Treatment options for this type of skin cancer vary depending on its size, location, and spread. Common approaches include: - Surgical excision to remove the tumor and some surrounding healthy tissue - Mohs surgery, a precise technique that aims to conserve as much healthy tissue as possible - Radiation therapy to destroy cancer cells, especially if surgery isn't suitable - Topical treatments like chemotherapy or immunotherapy for superficial lesions - Systemic therapies in cases where the cancer has spread to other parts of the body Following treatment, regular follow-up exams are vital to monitor for recurrence or new skin cancers. Patients are also advised to practice sun safety measures and perform self-examinations to detect changes early.
