the face, especially to the nose and cheeks, characterized by redness,
dilatation and enlargement of the bloodvessels, more or less acne and
hypertrophy.

#Describe the symptoms of acne rosacea.#

The disease may be slight or well-marked. Redness, capillary dilatation,
and acne lesions seated on the nose and cheeks, and sometimes on chin
and forehead also, constitute in most cases the entire symptomatology.

A mild variety consists in simple redness or hyperaemia, involving the
nose chiefly and often exclusively, and is to be looked upon as a
passive congestion; this is not uncommon in young adults and is
often associated with an oily seborrh[oe]a of the same parts. In many
cases the condition does not progress beyond this stage. In other
cases, however, sooner or later the dilated capillaries become
permanently enlarged (_telangiectasis_) and acne lesions are often
present--constituting the middle stage or grade of the disease; this is
the type most frequently met with. In exceptional instances, still
further hypertrophy of the bloodvessels ensues, the glands are enlarged,
and a variable degree of connective-tissue new growth is added; this
latter is usually slight, but may be excessive, the nose presenting an
enlarged and lobulated appearance (_rhinophyma_).

#Are there any subjective symptoms in acne rosacea?#

As a rule, no. Some of the acne lesions may be tender and painful, and
at times there is a feeling of heat and burning.

#What do you know in regard to the etiology?#

In many cases the causes are obscure. Chronic digestive and intestinal
disorders, anaemia, chlorosis, continued exposure to heat or cold,
menstrual and uterine irregularities, and the too free use of spirituous
liquors, tea, etc. are often responsible factors.

It is essentially a disease of adult life, common about middle age,
occurring in both sexes, but rarely reaching the same degree of
development in women as observed at times in men.

#Is acne rosacea easily recognized?#

Yes. The redness, acne lesions, dilated capillaries, and, at times, the
glandular and connective-tissue hypertrophy; the limitation of the
eruption to the face, especially the region of the nose; the evident
involvement of the sebaceous glands, the absence of ulceration, taken
with the history of the case, are characteristic.

It is to be distinguished from the tubercular syphiloderm and lupus
vulgaris,
