A vesicle is a fluid filled raised area (blister) >5mm = Bulla |

BCC's often manifest as pearly papules, often with prominent dilatedsub-epidermal blood vessels. What is the med term for these vessels? |
telan giec tasia= dilated subepidermal blood vessels |
|
Describe the morphology (macro) of seborrheic keratoses |
Round, exophytic, coinlike, flat plaque. Tan to dark brown & have a velvety to granular appearing surface
(Exophytic=tending to grow outward beyond the surface epithelium from which it)originates |
|
Actinic Keratoses morphology (macro) |
Tan brown or red
Scale & rough Hyperkeratotic |
|
Name this lesion: Round, flat plaques made up of proliferating monotonous epidermal basal cells.Hyperkeratosis & keratin filled cysts are characteristic. |
Seborrheic keratosis are Round, flat plaques made up of proliferating monotonous epidermal basal cells.Hyperkeratosis & keratin filled cysts are characteristic. |
|
Name this lesion: Present on sun exposed skin, these red/brown rough lesions show cytologic atypia in lower parts of epidermis & may (rarely) progress to carcinoma. |
Actinic Keratosis are present on sun exposed skin and show cytologic atypia in lower parts of epidermis. |
|
Describe the morphology (macro) of a SCC |
SCC's appear sharply defined, red, scaling plaques More advanced invasive lesions are nodular & may ulcerate. |
|
These lesions commonly arise from prior actinic keratoses? Name & describe how they look. |
SCC- defined red scaling plaque |
|
These lesions commonly arise from prior actinic keratoses? Name & describe how they look. |
SCC- defined red scaling plaque |
|
Name and describe (morphology) this lesion: Most common malignancy, slow growing, usually occurring in chronically sun exposed sites in fair skinned ppl. |
BCC is common slow growing cancer that rarely metastasis. Typically it is a pearly papule often with telangiactasia. |

Wheal |
urticaria |
|
erythema |

|
cyst: define and give an example |
closed sac containing fluid, semi fluid or solid contents. Acne is a common example. if encapsulated in the epidermis, it is an "epidermoid cyst". often punctated |
|
punctated |
means it has a "stalk" or a start. example is the starting point of the epidermal cyst |
|

ring shaped |

what term describes a layer of dried blood /serum/exudate. (as scab is an example) |
crust. |
|
what term describes a superficial loss of epidermis? what if it goes deeper into the dermis? |
Erosion. ulcer |
|
Weal – what is it and what is an example. |
an oedematous papule or plaque caused by swelling in the dermis. Wealing often indicates urticaria. |
|
what is lichenification? what is it the cause. |
epidermal thickening. due to constant friction/scratching/rubbing |
|
comedone |
keratin filled/plugged cyst lined by epithelial tissue |
