Dystrophic calcinosis cutis is the most prevalent kind of calcification on the skin. [2] The ectopic calcified mass usually consists of amorphous calcium phosphate and hydroxyapatite. [6] Dystrophic calcification is linked to a number of illnesses, such as infections, hereditary diseases, cutaneous neoplasms, and connective tissue diseases. [7]
A calcaneal spur (also known as a heel spur) is a bony outgrowth from the calcaneal tuberosity (heel bone). [ 1 ] Calcaneal spurs are typically detected by x-ray examination. [ 2 ] It is a form of exostosis. When a foot is exposed to constant stress, calcium deposits build up on the bottom of the heel bone.
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [ 1 ][ 2 ] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [ 3 ]
Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by abnormal calcification/bone formation (hyperostosis) of the soft tissues surrounding the joints of the spine, and also of the peripheral or appendicular skeleton. [ 1 ] In the spine, there is bone formation along the anterior longitudinal ligament and sometimes the ...
Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation. Dystrophic calcification can occur even if the amount of calcium ...
Haglund's deformity was first described by Patrick Haglund in 1927. It is also known as retrocalcaneal exostosis, Mulholland deformity, and ‘pump bump.'. It is a very common clinical condition, but still poorly understood. Haglund's deformity is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the ...
Osteophyte formation has classically been related to sequential and consequential changes in such processes. Often osteophytes form in osteoarthritic joints as a result of damage and wear from inflammation. Calcification and new bone formation can also occur in response to mechanical damage in joints. [5]
Osteitis fibrosa cystica (/ ˌ ɒ s t i ˈ aɪ t ɪ s f aɪ ˈ b r oʊ s ə ˈ s ɪ s t ɪ k ə / OSS-tee-EYE-tis fy-BROH-sə SIS-tik-ə) is a skeletal disorder resulting in a loss of bone mass, a weakening of the bones as their calcified supporting structures are replaced with fibrous tissue (peritrabecular fibrosis), and the formation of cyst-like brown tumors in and around the bone.
