Flashcards in Ch 24: Infections and Infestations, Primary Neoplasms Deck (11):
1

Superficial bacterial infection of the skin that occurs mostly in children. Characteristic honey-colored crusted erosions on hands, face, extremities

Impetigo

2

Bacterial (usually staph or strep) invasion of superficial skin forming necrotizing ulcerated lesion with neutrophils present

Ecthyma

3

Fungi that infect keratinized epithelium by producing keratinases

Dermatophytes

4

Benign neoplasms of melanocytes within the epidermis and/or dermis

Nevi

5

Nevi that do not follow a typical pattern of growth and differentiation

Dysplastic nevi

6

Neoplasm of melanocytes

Malignant melanoma

7

Melanomas are dependent to some extent on mutations in this gene

B-RAF

8

Melanoma growth phase characterized by horizontal growth along the epidermis and superficial dermis with a low risk of metastasis

Radial growth phase

9

Melanoma growth phase marked by growth into the deep dermis and associated with increased risk of metastasis. Most important prognostic factor in predicting metastasis

Vertical growth phase

10

Melanoma that bypasses the normal tumor progression and manifests malignant qualities in the initial lesion. It's usually in vertical growth phase when initially observed

Nodular melanoma

11

A large, pigmented macule due to chronic ultraviolet light exposure that occurs on sun-damaged skin of fair-skinned, usually elderly whites who have no history of acute sunburn injury, but often worked outdoors

Lentigo Maligna Melanoma (also known as Hutchinson melanotic freckle)
