Lentigo maligna melanoma is a type of skin cancer that develops from a long-standing lentigo maligna, a precursor to melanoma. It mainly appears on skin that has been frequently exposed to the sun, such as the face. This form of melanoma usually grows slowly but can eventually penetrate deeper into the skin and spread. Early detection and treatment are crucial to improve the chances of recovery.
Symptoms
- Large, flat, brownish patches, often on the face.
- Changes in size, color, or texture of the patch.
- Areas within the patch may become darker and develop a bumpy texture.
Causes
- Primarily caused by prolonged exposure to UV radiation from the sun.
- Genetic predisposition can also play a role.
Diagnosis
- Dermatological examination and skin biopsy.
- Dermatoscopy may be used to inspect suspicious areas.
Treatment
- Surgical removal is the most common treatment.
- Options such as radiotherapy, cryotherapy, or topical chemotherapy with cream may be considered for lentigo maligna.
- Regular follow-ups are essential to monitor for recurrence or progression.
Self-care Tips
- Regular self-examination of the skin.
- Strict sun protection with sunscreen and protective clothing.
- Avoiding peak sun exposure hours.
