- Excessive sun exposure can result in painful sunburn, but can also lead to other serious health problems, including melanoma, a life-threatening form of skin cancer.
- Melanoma is one of the fastest-growing forms of cancer.
- Children are at greatest risk, since serious sunburns during the first 18 years of life is believed to increase the risk of cancer by more than 50%.
- For those with sun-sensitive skin, fair complexions, light hair, or for those who spend excessive amounts of time in the sun
- in 1983, Drs. Kopf, Friedman and Rigel developed the A, B, C, D technique for diagnosing melanoma
- surface characteristics that can be seen by all, patients and doctors alike.
- A .... asymmetry,
- B .....border irregularity,
- C .....color variation
- D .....diameter over 6mm (1/4 of an inch).
| A symmetry |
not regularly round or regularly oval |
| B order |
notched, scalloped or poorly defined at the edges |
| C olor variation |
shades of brown, tan, red, white, blue or black alone or in any combination |
| D iameter |
6mm (the size of a pencil eraser) |
- Malignant melanoma represents approximately 5% of all skin cancers. Never the less, ALMOST 2/3 OF ALL DEATHS FROM SKIN CANCER ARE DUE TO MALIGNANT MELANOMA!
- Most cutaneous (skin) melanomas seem to develop without a history of a nevus.
The four forms of cutaneous melanoma are
1) lentigo maligna melanoma
2) superficial spreading melanoma
3) nodular melanoma
4) acral lentiginous melanoma.
- Primary malignant melanomas of the eyelid are extremely rare; they amount to 1% of all eyelid cancers.
- It has been estimated that an American's current lifetime risk for developing a skin melanoma is 1 in 128.
- Lentigo maligna (Hutchinson's melanotic freckle) is considered the premalignant lesion of lentigo maligna melanoma. It a represents 10% of all skin melanomas is the most common form in the head and neck areas.
- They are usually flat, tan to brown macule with irregular borders.
- Within the lesion, there may also be areas of white and grey. They most offen occur on sun-exposed facial skin in the elderly. See the photo above .
- is considered the more common form of melanoma. It represents 70% of skin melanomas. It usuallly involves nonexposed skin surfaces. It may appear on the nonexposed skin surfaces and a grow faster than lentigo maligna.
A patient with a suspected eyelid melanoma should have a careful examination, an incisional biopsy, and may ultimately require complete excision of the lesion and follow-up with an oncologist since this tumor can spread throughout the body.
Excision of the tumor can be performed by a MOHS surgeon, an dermatologist, or an ophthalmic plastic surgeon.
