If there is no induration, the result should be recorded as "0 mm".

The surface induration by means of this process is named case hardening.

Residual induration, however, is rare and usually these areas completely resolve.

The measurement of the induration is determined to be positive depending on risk factors.

Case hardening is a weathering phenomenon of rock surface induration.

The end result is a localized area of redness and induration that typically lasts a day or so.

In addition, there may be brownish-red pigmentation and induration.

The test is then read 48 to 72 hours later by measuring the size of the largest papule or induration.

Induration, contact bleeding and rolled margins are features of a malignant ulcer.

No hardening of tissue (induration) is felt.

Greater than 15 mm induration (Heaf 3 to 5)

Erythema and scleroderma-like induration occurs on the skin.

For example, a low-risk patient must have a larger induration for a positive than a high-risk patient.

Later in the disease, as induration subsides, erythema gives way to a ruddy or bruised color.

Induration - dermal thickening causing the cutaneous surface to feel thicker and firmer.

Among persons with HIV infection, 5 mm of induration is considered a positive (diagnostic) reaction.

Local swelling, hardening of tissue (induration)

Typical signs include periorbital erythema, induration, tenderness and warmth.

Treatment is mostly associated with mild to moderate injection-site reactions (local erithema, induration and pain), which disappear within 24-48 hours.

The person's medical risk factors determine at which increment (5 mm, 10 mm, or 15 mm) of induration the result is considered positive.

The condition was first described as "brown lung induration" by Rudolf Virchow in 1864 in patients after their death.

Other manifestations of reactogenicity typically assessed in such trials include bruising, redness, induration, and swelling.

Usually thre is an inflammatory reaction around the vein which presents a painful induration with erythema.

Disease occurs mainly in the skin and lymph nodes, causing induration, alopecia and eventual ulceration.

In other cases the skin reactions may be severe with marked pruritus and considerable erythema, oedema and induration.
