2 What are these Type of lesion: Type of lesion: Type of lesion:

3 What are these Type of lesion: Macular/patch
<- Café au lait Mongolian spot -> <- Lentigo Ephelid -> Type of lesion: Macule Type of lesion: Macule

4 Differentials Type of lesion: Macular/patch
<- Café au lait Mongolian spot -> Present at birth or early childhood Does not fade with age Light brown in hue Present anywhere Present at birth Fades with age Bluish in hue Limited to sacral lumbar area

5 Differentials Seen in young individuals
Lightens and darkens with sun exposure Related to sun exposure Typically seen in older individuals <- Lentigo Ephelid -> Type of lesion: Macule Type of lesion: Macule

6 What are these Type of lesion: Macular/patch <- Café au lait Small
Ephelid -> Small Fades with age? Lightens and darkens with season Large Does not fade with age Stable coloration. Surrounding skin may change color Type of lesion: Macule

7 What are these Type of lesion: Type of lesion: Type of lesion:

8 What are these Type of lesion: Macule Type of lesion: Slight papule
<- Junctional Nevus Compound Nevus-> <- Intradermal Nevi Sebhorreic Keratosis -> Type of lesion: papule Type of lesion: papule

9 <- Intradermal Nevi
Differentials <- Intradermal Nevi Sebhorreic Keratosis -> Keratotic psuedocysts Velvety texture ??Not velvety Melanocyte nests in dermis Type of lesion: papule Type of lesion: papule

10 What are these Type of lesion: Type of lesion: Type of lesion:

11 What are these Type of lesion: Macule Type of lesion: Macule
<- Junctional Nevus Dysplastic Nevus-> <- Halo Nevus Dermatofibroma-> Type of lesion: Macule Type of lesion: macule or papule

12 Differentials <- Halo Nevus Dermatofibroma->
Dimples when pinched Usually on legs Central white patch Outer white ring Type of lesion: Macule Type of lesion: macule or papule

13 Differentials Type of lesion: Macule Type of lesion: Macule
<- Junctional Nevus Dysplastic Nevus-> Usually regular color and edges Melanocyte nests at dermal epidermal junction Irregular border and color Nests of melanocytes stream horizontally

14 What are these Type of lesion: Type of lesion: Type of lesion:

15 What are these Type of lesion: Papule Type of lesion: Papule
<- Kerattoacantthoma Angioma: Pyogenic Granluoma -> <- Epidermoid Cyst Pilar Cyst-> Type of lesion: Papule Type of lesion: Papule

16 Differentials Type of lesion: Papule Type of lesion: Papule
<- Kerattoacantthoma Angioma: Pyogenic Granluoma -> Keratin center that looks like a dormant volcano Red vascular center that looks Like an active volcano.

17 Differentials <- Epidermoid Cyst Pilar Cyst->
Present on “hairless” areas Usually involves hairy areas Type of lesion: Papule Type of lesion: Papule

18 What are these Type of lesion: Type of lesion: Type of lesion:

19 What are these Type of lesion: Papule Type of lesion: Papule
<- Sebaceous Hyperplasia Syringoma -> <- Adenoma Sebaceum Verruca Plana -> Type of lesion: Papule Type of lesion: Papule

20 <- Sebaceous Hyperplasia
Differentials Type of lesion: Papule Type of lesion: Papule <- Sebaceous Hyperplasia Syringoma -> Forehead of men Sebaceous glands Below eye of women Eccrine glands

21 <- Adenoma Sebaceum
Differentials <- Adenoma Sebaceum Verruca Plana -> Flat warts. Central facial papules Type of lesion: Papule Type of lesion: Papule

22 What are these Type of lesion: Type of lesion: Type of lesion:

23 What are these Type of lesion: Papule Type of lesion: Papule?
<- Blue Nevus Venous Lake -> <- Fibroepithelial polyps Stucco Keratosis-> Type of lesion: Papule Type of lesion: Papule

24 What are these Type of lesion: Papule Type of lesion: Papule?
<- Blue Nevus Venous Lake -> Collection of venous blood Blanches when pressed Mole with deeper melanin Resulting in a blue color

25 Differentials <- Fibroepithelial polyps Stucco Keratosis->
Small mole like structures but Less well attached? Small Seborrheic Keratosis Type of lesion: Papule Type of lesion: Papule

26 What are these Type of lesion: Type of lesion: Type of lesion:

27 What are these Type of lesion: Macule/patch Type of lesion: macule?
