Specialty	Pathology

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]
