- A small knoblike prominence or excrescence, whether
natural or morbid; as, a tubercle on a plant; a tubercle on a bone; the
tubercles appearing on the body in leprosy. - A small mass or aggregation of morbid matter; especially,
the deposit which accompanies scrofula or phthisis. This is composed of
a hard, grayish, or yellowish, translucent or opaque matter, which
gradually softens, and excites suppuration in its vicinity. It is most
frequently found in the lungs, causing consumption.
