Ringworm of the body is an infection that
usually involves the trunk and upper extremities
and is uncommon in temperate climates.
SYMPTOMSThe lesions have raised
borders spread peripherally and clear centrally.
The various forms of this infection are pityriasis
rosea, seborrheic dermatitis, and psoriasis. Tinea
versicolor involves the upper trunk.
TREATMENTIt is the same as for tinea
Jock itch is a fungous infection occurring in
the area of the upper inner thighs. Growth of the
organisms is favored by obesity and tight clothing
and is often recurrent.
SYMPTOMSThey include severe itching
with active erythematous macules with sharp
margins and cleared centers.
TREATMENTAluminum acetate, corti-
costeroid lotion, or short-term oral corti-
costeroids may prove effective. Griseofulvin may
be indicated in chronic cases. Advise the patient
to rinse all soap away and dry thoroughly when
Athletes foot is a very common fungal infec-
tion of the feet.
SYMPTOMSNormally the third and fourth
interdigital spaces are first affected with
subsequent spreading to the plantar surfaces of
the arch. The lesions appear as macerated areas
with scaling borders. When the toenails are
involved, they become thickened and distorted.
Tinea pedis may be mistaken for maceration due
to excessive sweating.
TREATMENTKeep the feet clean and dry,
change socks frequently, and apply an antifungal
powder, ointment, or lotion.
This is a mild superficial fungal infection of
the skin that occurs normally in the trunk area.
Affected areas are resistant to tanning, and
the fungus is more likely to occur in individuals
who wear heavy clothing and tend to perspire
freely. It occurs most frequently in tropical
SYMPTOMSThere may be mild itching.
The lesions appear velvety and are chamois-
colored macules that are easily scraped off with
the fingernail. The trunk, upper arms, neck, and
face are often affected.

This condition is a parasitic skin infection
characterized by superficial burrows, intense
pruritus, and secondary inflammation. The
female itch mite burrows into the epidermis
and lays her eggs. The larva hatch, surface,
mate, and repeat the cycle. Good hygiene
helps prevent this infection. It is readily trans-
SYMPTOMSThere is severe itching,
especially at night. The male genitals, interdigital
spaces of the hand, flexor surfaces on the wrist,
areola of the breast in women, along the belt line
of the abdomen, and the area of the lower
buttocks are prone to inflammatory lesions. The
face is rarely involved in adults. The burrows may
be identified as fine, dark, wavy lines just beneath
the skin. It may be hard to detect the burrows due
to secondary lesions, A needle may be used to
remove the parasite from its burrow to facilitate
TREATMENT-General measures consist of
vigorous cleansing of papules and vesicles during
prolonged hot baths. Apply an emulsion or
lotion containing benzocaine and benzyl benzoate
from the area of the neck down. Reapply in 3 days
to destroy the larvae.
This is an infestation of the scalp, eyebrows,
