Derm Flashcards
A Nevus that initially appears as a flat hyperpigmented patch at birth
Beckets nevus
A wart like lesion that is often linear and appears on the limbs truck or scalp
Epidermal nevus (can be associated with skeletal defects, ocular complications, and CNS disease
A rare type of epidermal nevus of hair follicular origin, colllection of closely set dilated pores that comprise a larger plaque
Nevus comediconus
Nevus that typically appears on palms and soles
Partial dermal duct Nevus
cutaneous lesions have been described in early onset or late onset disease for Listeria
Only in early onset disease
Autoimmune disease autoantibodies against a component of the dermoepidermal junction. Tense blisters. Skin biopsy eospinophils, linear IgGand C3 along basement membrane on immunodluorescent staining
Bulbous pemphigoid
Congenital syphilis rash bullae on hands and feet only described in early onset disease
Pemphigus syphiliticum
Which bullae associated with staph produce sterile culture
Staph scalded skin syndrome has bullae with sterile culture, bullous impetigo can culture staph from bullae
Epidermolysis Bullosa:
1) simplex (AD)
2) junctional (AR)
3) dystrophic (AD-localized to distal extremities) (AR-involve skin and mucous membranes)
4) mixed
1) basal epidermal cells above basement membrane zone
2) through the basement membrane zone
3) superficial dermis
Incontinetia pigmenti , X-linked dominant, the rash develops into a verrucous eruption and then turns into area of pigment , then regresses into a linear hypopigmentation. Tzanck smear reveals…
Eosinophils
Acrodermatitis enteropathica
AR disorder; in which there is impaired zinc absorption
Wright stain
1) Erythema toxicum
2) neonatal pustular Melanosis
3) Miliaria
1) eosinophils
2) neutrophils
3) lymphocytes and sparse squamous cells
