Skin cancer is the most ________ form of all cancers.

Common

2

Superficial spreading melanoma (SSM)

Most common and most curable

3

Lentigo maligno melanoma (LMM)

Commonly located on the face and found an elderly patients as flat, brown, irregular patches

4

Moh's surgery

Helps save healthy skin reduces scarring
Often used on head and neck
Cancerous and small surrounding removed
Patient waits and pathologist examines
It cancer found more tissue removed

5

Curettage and electrodissection

Cancer scraped away, remaining cancer cells killed with electric needle, maybe scar so not used on face or visible areas

6

Cryosurgery

Abnormal cells frozen and killed with liquid nitrogen, used for small basil or squamous cell cancers

7

Skin creams

Chemotherapy cream treats small skin cancers on face or scalp

8

Laser surgery

Vaporized cancer cells with laser, relatively new method, used for cancer close to skin surface

9

Skin grafting and reconstructive surgery

May be needed if a large amount of skin had to be removed

10

Processing cancer by the ABCDE rule

A – asymmetry
B – border irregularity
C – color change
D – diameter of 6 mm or more
E – evolving in appearance

11

Malignant melanoma

5%, arising from melanocytes, can metastasized any organ, most deadly skin cancer, precise cause unknown

12

Superficial spreading melanoma (SSM)

Most common type and most curable

13

Lentigo maligno melanoma (LLM)

Commonly located on the face and found in elderly patients as flat, brown, irregular patches

14

Acrallentiginous melanoma (ALM)

Appears on the soles, palms, mucous membranes, and terminal phalanges; more common and Asian people and people with dark skin

Nodular melanoma (NM)

Occurs more often in men; believed to be a more aggressive type of melanoma that can develop and invade rapidly

16

Actinic keratosis (Solar keratosis)

Occurs in sun exposed areas, premalignant form of squamous cell carcinoma, irregularly shaped, flat, slightly erythematous with indistinct borders and overlying hard keratotic scale

17

Squamous cell carcinoma

20%, malignant neoplasm of keratinizing epidermal cells, less common, frequently occurs in sun exposed skin,
Early - opaque firm nodules with indistinct borders scaling and ulceration
Late - Covering of the lesion with scale

18

Basal cell carcinoma

75%, Locally invasive malignancy arising from epidermal basal cells, most common, least deadly
Nodular and ulcerative - small slowly enlarging papule w translucent or "pearly" borders, erosion, ulceration and depression of the center
Superficial - erythematous, sharply defined, barely elevated multinodular plaques with varying scaling and crusting

19

Signs of possible skin cancer

Oozing, bleeding, scaliness or change in the appearance of a bump or nodule.
Spread of pigmentation beyond border.
Change in sensation such as itchiness, tenderness or pain.
