athic atrophy of the skin, and give the treatment.#

General idiopathic atrophy of the skin is extremely rare, and is
characterized by a gradual, more or less general, degenerative and
quantitative atrophy of the skin structures, accompanied usually with
more or less discoloration and pigmentation.

Treatment is palliative and based upon indications.

#Describe parchment skin, and state the treatment.#

Parchment skin (_xeroderma pigmentosum_, _angioma pigmentosum et
atrophicum_) is a rare disease, the exact nature of which is not
understood. It is characterized by the appearance of numerous
disseminated, freckle-like pigment-spots, telangiectases, atrophied
muscles, more or less shrinking and contraction of the integument, and
followed, in most instances, by epitheliomatous tumors and ulceration,
and finally death. It is usually slow in its course, beginning in
childhood and lasting for years. It is not infrequently seen in several
children of the same family.

Treatment is palliative, consisting, if necessary, of the use of
protective applications and of the administration of tonics and
nutrients.

#Describe atrophic lines and spots.#

Atrophic lines and spots (_striae et maculae atrophicae_) may be idiopathic
or symptomatic, the lesions consisting of scar-like or atrophic-looking,
whitish lines and macules, most commonly seen on the trunk. They are
smooth and glistening. Slight hyperaemia usually precedes their
formation. As an idiopathic disease its course is insidious and slow,
and its progress eventually stayed. The so-called _lineae albicantes_,
resulting from the stretching of the skin produced by pregnancy or
tumors, and from rapid development of fat, may be mentioned as
illustrating the symptomatic variety.

In course of time the atrophy becomes less conspicuous.

#Describe senile atrophy.#

Senile atrophy is not uncommon, the atrophy resulting, as the name
inferentially implies, from advancing age. It is characterized by
thinning and wasting, dryness, and a wrinkled condition, with more or
less pigmentation and loss of hair. Circumscribed pigmentary deposits
and seborrh[oe]a, with degeneration, are also noted.

#What several diseases of the skin are commonly followed by atrophic
changes?#

Favus, lupus, syphilis, leprosy, scleroderma and morph[oe]a.
