Treatment, which is rapidly effective, is the same as that employed in
tinea versicolor.

#Dhobie Itch.#

Dhobie itch is a name used in certain tropical countries to designate a
somewhat peculiar itching eruption of the genitocrural and axillary
regions, and by some also a similar eruption about the feet. It consists
of a dermatitis of variable degree, usually with a festooned, irregular
border, with considerable itching. It is believed that such cases are
variously due to the trichophyton of ringworm, to the microsporon furfur
of tinea versicolor, to the microsporon minutissimus of erythrasma, and
to other parasites.

#Actinomycosis.#

#Describe actinomycosis.#

Actinomycosis of the skin is an affection due to the ray fungus, and
characterized by a sluggish, red, nodular, or lumpy infiltration,
usually with a tendency to break down and form sinuses. The affection
may involve almost any part, but its most common site is about the jaw,
neck, and face. As a rule, the first evidence is a hard subcutaneous
swelling or infiltration, which may increase slightly or considerably.
The overlying skin gradually becomes of a sluggish or dark-red color.
Softening ensues, and the diseased area breaks down at one or more
points, from which there oozes a discharge of a sero-purulent, purulent,
or sanguinolent character. In this discharge can be usually noted
minute, friable, yellowish or yellowish-gray bodies representing
conglomerate collections of the causative fungus.

The course of the malady is commonly slow and insidious. Unless systemic
pyemic infection occurs or the fungus elements find their way to the
deeper organs or structures the general health remains apparently
undisturbed.

#What is the treatment?#

The administration of moderate to large doses of potassium iodide,
conjointly with curetting or excision of the diseased mass. Local
applications of iodine solution can also be tried.

#Blastomycetic Dermatitis.#

#What do you understand by blastomycetic dermatitis?#

Blastomycetic dermatitis is a rare disease beginning usually as a small
papule or nodule, enlarging slowly, breaking down and developing into a
verrucous or papillomatous-looking area, similar in appearance to
tuberculosis cutis verrucosa. A muco-purulent or purulent secretion can
visually be pressed out from between the papillomatous elevati
