Calcifications located in the dermis of the breast may appear indistinguishable from intramammary calcifications. The authors present a sign, called the tattoo sign, that can help radiologists identify dermal calcifications. When mammograms are compared, calcifications that maintain a fixed relationship to each other suggest a dermal location. This can be verified with standard techniques. Understanding the tattoo sign may help prevent unnecessary needle localization and biopsy procedures.
位于乳房真皮层的钙化可能看起来与乳腺内钙化难以区分。作者提出了一种称为“纹身征”的征象，可帮助放射科医生识别真皮层钙化。当比较乳房X线照片时，彼此保持固定关系的钙化提示为真皮层位置。这可以通过标准技术进行验证。了解“纹身征”可能有助于避免不必要的穿刺定位和活检操作。
