Fever and Rash Flashcards
Name the lesion
flat lesions defined by an area of changed color <5mm
macule
Name the lesion
raised, solid lesions < 5mm in diameter
papule
Name the lesions
lesions >5 mm in diameter with a flat,plateau like surface, elevated borders
plaque
Name the lesion
>5mm diameter with a more rounded configuration
Nodule
Name the lesion
- papules or plaques that are pale pink and may appear annular (ringlike) as they enlarge
- Classic (nonvasculitic) wheals are transient, lasting only 24-48 hours in any defined area
Wheals
Name the lesion
circumscribed, elevated lesions containing fluid <5 mm
vesicle
Name the lesion
circumscribed, elevated lesions containing fluid >5mm
bullae
Name the lesion
Raised lesions containing purulent exudate <5mm
pustule
Name the lesion
<3mm in diameter the purpuric lesions are
petechiae
Name the lesion
>3 mm purpuric lesions
ecchymoses
Name the lesion
a raised lesion due to inflammation of the vessel wall (vasculitis) with subsequent haemorrhage
Palpable purpura
Name the lesion
a defect in the skin extending at least into the upper layer of the dermis
Ulcer
Name the lesion
a necrotic lesion covered with a black crust
Eschar
cause of palpable purpura triggered by penicillins, sulfa drugs, salicylates
Serum sickness
Name the rash
Lesions evolve from macular to petechial, start on the wrist and ankles, spread centripetally and appear on the palms and soles
Secondary syphilis
Name the rash
tender vesicles distributed peripherally and in the mouth
Hand foot mouth disease
Name the rash
develops symmetrically on the elbow,knee, palms and soles, can involve mucosal surfaces – Stevens-johnson syndrome
Erythema multiforme
Name the rash
Osler node and Janeway lesion in hand
Endocarditis
Name the rash
facial flush, strawberry tongue, accentuated petechiae in body folds (pastia’s lines)
Scarlet fever
Name the rash
patients,fissuring of the lips,strawberry tongue ,conjunctivitis, adenopathy
Kawasakit disease
Name the rash Diffuse erythema involving palms; pronounced erythema of mucosal surfaces; conjunctivitis; desquamation 7–10 days into illnes
Staphylococcal toxic shock syndrome
Name the rash
Scarlatiniform rash that May occur in setting of
severe infections (e.g., necrotizing fasciitis,
bacteremia, pneumonia
Streptococcal toxic shock syndrome
Name the rash
Diffuse tender erythema, often with bullae
and desquamation; Nikolsky’s sign
Staphylococcal scalded skin syndrome
Name the rash
Diffuse erythema or target lesions progressing to bullae
Sloughing and necrosis of entire epidermis <10%
Steven Johnson Syndrome
Name the rash
Macules (2–3 mm) evolving into papules,
then vesicles (sometimes umbilicated), on
an erythematous base (“dewdrops on a rose
petal”); pustules then forming and crusting;
lesions appearing in crops; may involve
scalp, mouth; intensely pruritic
Varicella
Name the rash
Pruritic,erythematous follicular, papular, vesicular,or pustular lesions that involve axillae, buttocks,abdomen and areas occluded by bathing suits
Pseudomonas “ hot tub folliculitis”
Name the rash
Red macules on tongue and palate evolving
to papules and vesicles; skin macules
evolving to papules, then vesicles, then
pustules over 1 week, with subsequent
lesion crusting; lesions initially appearing
on face and spreading centrifugally from
trunk to extremities; differs from varicella in
that (1) skin lesions in any given area are at
same stage of development and (2) there is
a prominent distribution of lesions on face
and extremities (including palms, soles)
Variola (smallpox)
Name the rash
Erythema rapidly followed by hallmark
painful grouped vesicles that may evolve into
pustules that ulcerate, especially on mucosal
surfaces; lesions at site of inoculation:
commonly gingivostomatitis for HSV-1 and
genital lesions for HSV-2; recurrent disease
milder (e.g., herpes labialis does not involve
oral mucosa)
Primary herpes simplex
virus (HSV) infection
Name the rash
Pruritic papule enlarging and evolving into a 1x3 cm painless ulcer sorrounded by vesicles, then developing a central eschar with edema;residual scar
Anthrax
Name the rash
Ulceroglandular form
A tender eryhthematous paule evolves into a necrotic,tender ulcer with raised border
Tularemia
Patient comes in with rash and you are suspecting an infection. Give the top 2 tests that you’d order
CBC with differential
Blood culture and other sites
Which diagnostic imaging should be done in acutely ill px?
Chest radiography
When is skin biopsy indicated?
later in the diagnostic process of conditions with skin lesions
