Lentigo maligna
Lentigo Maligna
Lentigo Maligna (pronunciation: len-TI-go mal-IG-na) is a type of melanoma that typically occurs on the sun-exposed skin of elderly individuals. It is a slow-growing form of skin cancer that is often associated with long-term sun exposure.
Etymology
The term "Lentigo Maligna" is derived from the Latin word "lentigo", meaning freckle, and the Latin word "maligna", meaning malignant or harmful.
Definition
Lentigo Maligna is a type of melanoma in situ, which means it is a melanoma that is confined to the outermost layer of the skin, the epidermis. It is characterized by a flat, mottled, and irregularly shaped patch of skin that is brown to black in color.
Symptoms
The primary symptom of Lentigo Maligna is a flat, irregularly shaped patch of skin that slowly enlarges over time. The patch may be a variety of colors, including tan, brown, black, or pink. It is most commonly found on the face, neck, or arms, but can occur anywhere on the body.
Diagnosis
Diagnosis of Lentigo Maligna is typically made through a biopsy, where a small sample of the affected skin is removed and examined under a microscope.
Treatment
Treatment options for Lentigo Maligna include surgical removal of the affected skin, Mohs surgery, radiation therapy, and topical treatments. The choice of treatment depends on the size and location of the lesion, as well as the patient's overall health.
