Answer 2

Cherry Angioma

Question 3

Pink/brown firm papule; composed of collagen, fibroblasts, capillaries; dimples inward when pressed w/ two fingers

Answer 3

Dermatofibroma

Question 4

yellow papules w/ umbilicated center -> very similar looking to molluscum; common on forehead/nipples/genitalia of adults; caused by hypertrophy of sebaceous glands; a side effect of cyclosporine in transplant pts.

Answer 4

Sebaceous hyperplasia

Question 5

Raised from plaques which extend beyond wound margin; more common in black/brown ptr; increased dermal fibroblasts and collagen blunders; can occur after injury, surgery, or spontaneously

Answer 5

Keloid

Question 6

flesh-colored module w/ central punctum (opened w/ black keratin debris); common on face and trunk; Not a sebaceous cyst, nothing to do with w/ sebaceous gland

Answer 6

Epidermoid cyst

Question 7

the flesh-colored module on the scalp; no punctum ( how to distinguish from epidermoid cyst); surgical removal/ incursion for tx

Answer 7

Answer 10

Senile purpura/ solar purpura/ actinic purpura

Question 11

the proliferation of melanocytes after birth; 3 types- Junctional nevi; dark brown to black macule, melanocyte proliferation in the epidermis; compound nevi; brown raised or dome-shaped papule, melanocyte proliferation in epidermis + dermis; Intradermal; light brown to a skin-colored elevated dome-shaped papule, melanocyte proliferation in dermis

Answer 11

Benign Nevi (Acquired melanocytic nevi)

Question 12

caused by the proliferation of melanocytes during embryogenesis; size and shape varies -> dictates risk for melanoma

Answer 12

Congenital Nevi (birthmarks)
