1
Fungal infections are caused by microscopic
organisms (fungi) that can live on the skin. They can
live on the dead tissues of the hair, nails, and outer
skin layers.
2
3
Superficial fungal infections are known as
dermatophytoses.
The most common are:
tinea capitis,
tinea corporis,
tinea cruris, and
tinea pedis.
4
Tinea refers to the common disorder
known as “ringworm.”
The name comes from its characteristic
ring-shaped lesion and the location of
infection.
5
Etiology/pathophysiology
Microsporum audouinii major fungal
pathogen
Tinea capitis - Ringworm of the scalp
Tinea corporis - Ringworm of the
body
Tinea cruris - Jock itch
Tinea pedis (most common) Athlete’s foot
6
Tinea
capitis
Erythematous around lesion with
pustules around the edges and
alopecia at the site
The hair can break off at the scalp, and
hair loss is typically not permanent.
7
(From Habif, T.P. [2004]. Clinical dermatology: a color guide to diagnosis and therapy. [4th ed.]. St. Louis: Mosby.)
Tinea capitis.
8
Clinical manifestations/assessment
Tinea corporis
Tinea corporis refers to ringworm of
the body.
Flat lesions—clear center with red
border, scaliness, and pruritus
Outbreaks are typically in hairless
areas.
9
Tinea Corporis
10
Clinical manifestations/assessment
Tinea cruris
Brownish-red lesions in groin area,
severe pruritus with skin excoriation
due to intense scratching
These lesions migrate outward from
the groin region.
11
Tinea cruris, also known informally as
crotch itch or jock itch in American
English and dhobi itch or scrot rot in
British English, is a dermatophyte fungal
infection of the groin region in either sex,
though more often seen in males.
12
The type of fungus that most commonly
causes tinea cruris is called Trichophyton
rubrum.
Some other contributing fungi are
Candida albicans,
Trichophyton mentagrophytes and
Epidermophyton floccosum.
13
14
15
16
Clinical manifestations/assessment
Tinea pedis
Fissures and vesicles around and
below toes
Tinea pedis is also known as
“athlete’s foot.”
This infection is associated with
more skin maceration than the other
types of tinea.
17
18
19
Diagnostic tests
Visual inspection
Ultraviolet light for tinea capitis
Infected hair becomes fluorescent
(blue-green) under the light
20
Medical management
Griseofulvin—oral
Antifungal soaps and shampoos
Tinactin or Desenex
Burrow’s solution (tinea pedis)
21
Nursing Interventions
The feet should be cleaned and dried
thoroughly, paying special attention to the
toes.
Proper application of medications and
warm compresses
Excellent foot care is stressed.
Wearing sandal-type shoes or going
barefoot helps decrease foot moisture.
22
23
Superficial inflammation of the skin is known as
dermatitis.
It can be caused by numerous agents, such as
drugs, plants, chemicals, metals, and food.
The nurse first observes erythema and edema,
followed by the eruption of vesicles that rupture
and encrust.
Pruritus is always present, which promotes
further skin excoriation.
24
1. Contact dermatitis
2. Dermatitis venenata, exfoliative dermatitis, and
dermatitis medicamentosa
3. Urticaria
4. Angioedema
5. Eczema (atopic dermtitis)
6. Acne vulgaris
7. Psoriasis
8. Systemic lupus erythematosus
25
Contact dermatitis – The epidermis is
inflammed and damaged
Etiology/pathophysiology
Direct contact with agents of
hypersensitivity
Detergents, soaps, industrial
chemicals, plants
26
Clinical manifestations/assessment
Burning
Pain
Pruritus
Edema
Papules and vesicles
27
Diagnostic tests
Health history –
(1) tried a new soap,
(2) been traveling and using different
personal items, or
(3) been working with plants or
flowers
28
Diagnostic tests
Intradermal skin testing
Elimination diets
Elevated serum IgE levels and
eosinophilla support the diagnosis.
It is thought that both tests relate to
abnormalities of T-cell function.
29
Medical management/nursing
interventions
Remove cause
Burrow’s solution
Corticosteroids to lesions
Cold compresses
Antihistamines (Benadryl)
30
Nursing Interventions
The primary goal is to identify the offensive
agent so as to rest the involved skin and protect
it from further damage.
Wet dressings, using Burow’s solution, help
promote the healing process.
A cool environment with increased humidity
decrease the pruritus.
Cold compresses may be applied to decrease
circulation to the area (vasoconstriction).
31
Nursing Interventions
Daily baths to cleanse the skin should be taken
with an application of oil.
Fingernails should be cut at the level of the
fingertips to decrease excoriation from
scratching.
Clothing should be lightweight and loose to
decrease trauma of the involved area.
32
Prognosis
Removal of the offensive agent results in
full recovery.
Desensitizing the individual may be
necessary if recurrences are frequent.
33
Dermatitis venenata, exfoliative
dermatitis, and dermatitis medicamentosa
Etiology/pathophysiology
Dermatitis venenata: Contact with certain
plants
Exfoliative dermatitis: Infestation of heavy
metals, antibiotics, aspirin, codeine, gold, or
iodine
Dermatitis medicamentosa: Hypersensitivity
to a medication
34
Clinical manifestations/assessment
Mild to severe erythema and pruritus
Vesicles
Respiratory distress (especially with
medicamentosa)
35
Exfoliative
Dermatitis
36
Medical management/nursing
interventions
All dermatitis
Colloid solution, lotions, and ointments
Cordicosteroids
37
Medical management/nursing
interventions
Dermatitis venenata
Thoroughly wash affected area
Cool, wet compresses
Calamine lotion
38
Medical management/nursing
interventions
Dermatitis medicamentosa
Discontinue use of drug
39
Etiology/pathophysiology
Presence of wheals or hives in an allergic
reaction commonly caused by drugs, food,
insect bites, inhalants, emotional stress, or
exposure to heat or cold.
The wheals (round elevation of the skin; white
in the center with a pale red periphery) of
urticaria appear suddenly.
Urticaria or hives is caused by the release of
histamine in an antigen-antibody reaction.
40
Etiology/pathophysiology
Clinical manifestations/assessment
Pruritus
Burning pain
Wheals
41
42
43
Diagnostic tests
Health history

Epinephrine
44
Nursing Interventions
Identify and alleviate cause
Therapeutic bath
Teach patient possible causes and
prevention
The signs and symptoms of an
anaphylactic reaction should be
reviewed to include shortness of
breath, wheezing, and cyanosis.
45
Prognosis
Patient recover fully when the
offensive agent is determined and
avoided.
Compliance with the therapeutic
treatment regimen influences the
outcome.
46
Etiology/pathophysiology
Form of urticaria
Occurs only in subcutaneous tissue
Same offenders as urticaria
Common sites: eyelids, hands, feet,
tongue, larynx, GI, genitalia, or lips
47
Clinical manifestations/assessment

lips, etc.)
48

Epinephrine
Corticosteroids (Solu-Medrol®)
Cold compresses
50
Nursing interventions
Cold compresses
Respiratory assessment, continuous
Medical alert
Education and teaching for prevention
Prognosis
With early treatment, the prognosis is
good
51
Etiology/pathophysiology

released and an antigen-antibody
reaction occurs
Primarily occurs in infants
The common allergies are to chocolate,
eggs, wheat, and orange juice.
52
Clinical manifestations/assessment
Pruritus
Papules and vesicles on scalp,
forehead, cheeks, neck, and extremities
The vesicles generally rupture,
discharging a yellow, tenacious
exudates that dries and encrusts.

Prevention of Skin Cancer
The American Academy of Dermatology (AAD)
has recommended these three preventive steps
for prevention of skin cancer:
Wear protective clothing, including a hat with
a 4-inch brim.
Apply sunscreen all over the body and avoid
sun from 10 am to 3 pm.
Regularly use a broad-spectrum sunscreen
with a skin protection factor (SPF) of 15 or
higher, even on cloudy days.
94
Prevention of Skin Cancer
The following six steps have been recommended
by the AAD and the Skin Cancer Foundation to
help reduce the risk of sunburn and skin
cancer:
1. Minimize exposure to the sun at midday-between 10
AM and 3 PM.
2. Apply sunscreen, with at least an SPF 15 or higher
that protects against both ultraviolet A (UVA) and
ultraviolet B (UVB) rays, to all areas of the body that
are exposed to the sun.
3. Reapply sunscreen every 2 hours, even on cloudy
days. Reapply after swimming or perspiring.
95
Prevention of Skin Cancer
4. Wear clothing that covers the body and shades
the face.
Hats should provide shade for both the face and
back of the neck.
Wearing sunglasses reduces the amount of rays
reaching the eyes by filtering as much as 80% of
the rays, and protecting the eyelids as well as the
lenses.
96
Prevention of Skin Cancer
5. Avoid exposure to UV radiation from sunlamps
and tanning parlors.
6. Protect children. Keep them from excessive sun
exposure when the sun is stronger (10 AM to 3
PM), and apply sunscreen liberally and
frequently to children ages 6 months and older.
