1 Slackers Guide to Skin Lesions

2 What are these Type of lesion:

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

4 Differentials <- 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 Type of lesion: Macular/patch

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

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

7 What are these Type of lesion:

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

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

10 What are these Type of lesion:

11 What are these 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-> Type of lesion: MaculeType of lesion: macule or papule Dimples when pinched Usually on legs Central white patch Outer white ring

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

14 What are these Type of lesion:

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

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

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

18 What are these Type of lesion:

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

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

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

22 What are these Type of lesion:

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

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

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

26 What are these Type of lesion:

27 What are these Type of lesion: macule?Type of lesion: Macule/patch Type of lesion: <-Angioma:Telangiectasia Angioma :Spider->

28 What are these Type of lesion:

29 What are these Type of lesion: Papule? <- Pustular Psoriasis Erythema Multiforme -> <- Gutate psoriasis Herpes Zoster -> Type of lesion: Papule

30 Differentials <- Pustular Psoriasis Erythema Multiforme -> Targetoid lesions Diffuse

31 Differentials <- Gutate psoriasis Herpes Zoster -> Itchy Painful Follows dematome

32 What are these

33 <- Varicella (Chicken Pox) Lichen Planus -> <- Urticaria Mobiliform->

34 Differentials <- Varicella (Chicken Pox) Lichen Planus -> Dew drop on rose pattern Itchy Widespread Caused by Varicella Pruritic, purple, polygonal, polymorphous papules Wrists, oral whitish reticulation

35 Differentials <- Urticaria Mobiliform-> Angioedema Transient Rapid changes Can be localized or diffuse Resembles measles Erythematous papules coalsescing into plaques

36 What are these

37 <- Bullous Pemphigoid Pemphigus Vulgaris -> <- Psoriasis Seborrheic Dermatitis->

38 Differentials <- Bullous Pemphigoid Pemphigus Vulgaris -> Tense blisters Flaccid blisters

39 Differentials <- Psoriasis Seborrheic Dermatitis-> Erythematous plaques with silvery scale Especially on elbows and knees Pitting of nails common In sebaceous areas

40 What are these <- Dyshidrotic Eczema Molluscum Contagiosum -> <- Impetigo Atopic Dermatitis->

41 Differentials <- Dyshidrotic Eczema Molluscum Contagiosum -> Itchy Small blisters on hands and feet Non contagious Small fleshy pearlescent papules Caused by pox virus Contagious – std in adults

42 Differentials <- Impetigo Atopic Dermatitis-> Honey colored Staph or strep infection Aggravated by allergens in environment
