Hyperostosis

	Exostoses - Benign hypertrophy that projects outward from the surface of bone, often containing a cartilaginous component.
	Hyperostosis, Diffuse Idiopathic Skeletal - A disease of elderly men characterized by large osteophytes that bridge vertebrae and ossification of ligaments and tendon insertions.
	Hyperostosis, Sternocostoclavicular - A rare, benign rheumatologic disorder or syndrome characterized by hyperostosis and soft tissue ossification between the clavicles and the anterior part of the upper ribs. It is often associated with the dermatologic disorder palmoplantar pustulosis, particularly in Japan. Careful diagnosis is required to distinguish it from psoriatic arthritis, OSTEITIS DEFORMANS, and other diseases. Spondylitis of pustulosis palmaris et plantaris is one of the possible causes; also, evidence suggests one origin may be bone infection. Bone imaging is especially useful for diagnosis. It was originally described by Sonozaki in 1974.
