Excessive connective-tissue growth, exceptionally met with, is to be

#Describe acne varioliformis.#

Acne varioliformis is characterized by lesions of a moderately
superficial papulo-pustular type, which in disappearing leave slight or
pit-like scars. The forehead and scalp are the favorite sites, but they
may also occur elsewhere. The eruption is rather scanty as a rule,
consisting usually of ten to thirty lesions. They begin as small
maculo-papules, as papules, or as minute nodules in or on the skin, and
gradually become small pea-sized, with a tendency to slight vesiculation
or pustulation at the central part. The lesion is sluggish in its
course, drying to a thin crust, which finally falls off, leaving a
depressed variola-like scar. New lesions arise from time to time, and
the disease thus continues almost indefinitely. There may or may not be
itching. In what appears to be a variety of this disease, known usually
as _acne urticata_, there is considerable itching just at the time the
lesion is appearing. The malady is not frequent, but occurs in both
sexes, usually in those between the ages of twenty and fifty. It seems
probable that the eruption is parasitic in origin.

The maladies variously known as hydradenitis suppurativa, acnitis,
spiradenitis, folliclis, granuloma necroticum, etc., in which the
lesions, primarily at least, are somewhat deeper seated, sluggish in
their course, and followed by scarring, could be also included under
this head.

#Give the prognosis and treatment.#

The disease is rebellious and tends to recur. The most efficient
applications are those of sulphur and resorcin, the same as prescribed
in ordinary acne.

#Sycosis.#
(_Synonyms:_ Sycosis Vulgaris; Sycosis Non-parasitica; Folliculitis
Barbae; Sycosis Coccogenica.)

#What do you understand by sycosis?#

Sycosis is a chronic, inflammatory affection involving the
hair-follicles, usually of the moustache and bearded regions only, and
characterized by papules, tubercles, and pustules perforated by hairs.

#Describe the symptoms of sycosis.#

Sycosis begins by the formation of papules and pustules about the
hair-follicles; the lesions occur
