C44.399

Clinical Causes: Chronic exposure to ultraviolet (UV) radiation from the sun or tanning beds Repeated skin injuries or wounds Carcinogenic exposures such as industrial chemicals or certain dyes A weakened immune system Genetic predispositions that increase susceptibility to skin cancers History of radiation therapy to the face Age, with increased risk in older individuals Fair skin, light hair, and light eyes, which offer less natural protection against UV rays

Key Symptoms: Persistent skin lesions or sores that do not heal Growth or thickening within a skin lesion Changes in the appearance of a mole or patch, such as color, shape, or size Unusual or new skin growths on the face Bleeding or oozing from a skin lesion Soreness or tenderness in a specific area of the face Crusting or ulceration of skin over time Visible abnormal tissue or nodules on facial skin

Diagnosis Path: Conduct a thorough physical inspection of the affected area on the face Review the patient's medical history and potential risk factors Perform a skin biopsy, where a small sample of skin tissue is removed and examined under a microscope Use imaging studies such as dermoscopy, ultrasound, or X-rays if the extent of spread needs to be assessed Evaluate for signs of metastasis if the tumor appears aggressive or has unusual features

Treatment Protocols: Surgical excision to remove the tumor along with a margin of healthy tissue Mohs micrographic surgery for precise removal, especially in delicate or cosmetically sensitive facial areas Radiation therapy to target residual cancer cells when surgery isn't feasible or as adjunct treatment Cryotherapy, which uses extreme cold to destroy abnormal tissue Topical treatments like chemotherapy or immunotherapy creams in some cases Systemic therapies such as targeted therapy or chemotherapy for advanced or metastatic cases Follow-up care to monitor for recurrence or new skin lesions
