nodule - (mineralogy) a small rounded lump of mineral substance (usually harder than the surrounding rock or sediment) mineralogy - the branch of geology that studies minerals: their structure and properties and the ways of distinguishing them.
A nodule is a small mass of tissue which forms in or on the body, usually in response to injuries. Nodules are typically hard and they can be easily felt. For the most part, the masses are benign, requiring no medical action, but sometimes they can interfere with the function of the body, or they may be malignant.
