#What is the treatment?#

The usual plan is to prick or incise each lesion and press out the
contents. In some milia it may be necessary also, in order to prevent a
return, to touch the base of the excavation with tincture of iodine or
with silver nitrate. Electrolysis is also effectual. In those cases
where the lesions are numerous the production of exfoliation of the
epiderm by means of resorcin applications (see acne) is a good plan.

#Steatoma.#
(_Synonyms:_ Sebaceous Cyst; Sebaceous Tumor; Wen.)

#Describe steatoma.#

Steatoma, or sebaceous cyst, appears as a variously-sized, elevated,
rounded or semi-globular, soft or firm tumor, freely movable and
painless, and having its seat in the corium or subcutaneous tissue. The
overlying skin is normal in color, or it may be whitish or pale from
distention; in some a gland-duct orifice may be seen, but, as a rule,
this is absent.

#What are the favorite regions for the development of steatoma?#

The scalp, face and back. One or several may be present.

#What is the course of sebaceous cysts?#

Their growth is slow, and, after attaining a variable size, may remain
stationary. They may exist indefinitely without causing any
inconvenience beyond the disfigurement. Exceptionally, in enormously
distended growths, suppuration and ulceration result.

#What is the pathology?#

A steatoma is a cyst of the sebaceous gland and duct, produced by
retained secretion. The contents may be hard and friable, soft and
cheesy, or even fluid, of a grayish, whitish or yellowish color, and
with or without a fetid odor; the mass consisting of fat-drops,
epidermic cells, cholesterin, and sometimes hairs.

#Are sebaceous cysts likely to be confounded with gummata?#

No. Gummata grow more rapidly, are usually painful to the touch, are not
freely movable, and tend to break down and ulcerate.

#Describe the treatment of steatoma.#

A linear incision is made, and the mass and enveloping sac dissected
out. If the sac is permitted to remain, reproduction almost invariably
takes place.

#CLASS II.--INFLAMMATIONS.#

#Erythema Simplex.#

#What do you understand by erythema simplex?#

Erythema simplex is a hyperaemic disorder characterized by redness,
occurring in the form of variously-sized and shaped, diffused or
circumscribed, non-elevated patches.
