Skin calcifications in the breast usually form in dermal sweat glands after low grade folliculitis and inspissation of sebaceous material. Calcifications may also form in moles and other skin lesions. Often, these calcifications are in groups as they extend into small glands in the skin. Occasionally, tangential views are performed to verify that questionable calcifications are located in the skin.
Dermal calcifications are usually related to a chronic inflammatory process such as folliculitis.
