Question 24

describe scale

Answer 24

healed up keratanised cells
flaky skin, irregular shape
thick or thin, dry or oily
variation is size

describe lichinifecation

Answer 25

rough thickened epidermis secondary to persistent rubbing ithing or skin irritation often involves flexor surface or extremities

Question 26

describe keloid

Answer 26

irregular shape, elevated, progressivley enlarges scar grows beyond boundaries of wounds caused by excessive collage fomartion during healing

Question 27

Answer 30

loss of part of epidermis depressed, moist, glisteming follows rupture of vessicle or bula

Question 31

describe ulcer

Answer 31

loss of epidermis and dermis concave varies in size

Question 32

describe atrophy

Answer 32

thinning of skin and surface and loss of skin markings

Question 33

what does neoplasian / neoplasam mean?

Answer 33

new formation | abnormal growth of cells

Question 34

what are malignant tumours

Answer 34

grow rapidly look different to surrounding cells (anaplatic) lack organisation spread and invade other tissues and structures (metastasis)

Question 35
