Nodule (medicine)

Nodule
SpecialtyPathology

In medicine, nodules are small firm lumps, usually greater than 1 cm in diameter.[1][2] If filled with fluid they are referred to as cysts.[2] Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules.[3]

The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any associated symptoms which may give clues to an underlying medical condition.[4]

Nodules in skin include dermatofibroma[5] and pyogenic granuloma.[6] Nodules may form on tendons and muscles in response to injury,[7] and are frequently found on vocal cords.[8] They may occur in organs such as the lung,[9] or thyroid,[10] or be a sign in other medical conditions such as rheumatoid arthritis.[11]
