營養不良性鈣化（dystrophic calcification），「營養不良」指的是局部組織的營養不良，而非全身性的營養不良，有可能是因為組織受傷導致局部組織的營養不良，引起鈣磷乘積及鈣鹽沉積增加，超過了鈣鹽的溶解度積，從而形成鈣化。
Dystrophic calcification refers to the abnormal deposition of calcium salts in previously damaged tissues. Unlike metastatic calcification, dystrophic calcification occurs in local areas of tissue necrosis or injury, where calcium and phosphate products accumulate and exceed the solubility product, leading to the formation of calcium deposits.
營養不良性鈣化（dystrophic calcification）可能導致鈣化的發生部位：
Common sites of dystrophic calcification include:
動脈粥狀硬化血管壁鈣質沉積
Atherosclerotic blood vessel walls
胰臟炎周邊脂肪組織鈣質沉積
Peripancreatic adipose tissue following pancreatitis
心臟瓣膜受損發生鈣質沉積
Damaged heart valves
