Perieccrine calcification and concentric calcification patterns may help distinguish classic calciphylaxis (CPX) from incidental cutaneous vascular calcification (CVC). These findings aid in diagnosing CPX, especially when pseudoxanthoma elasticum-like changes are present.
Area of Science:
- Dermatology
- Pathology
- Nephrology
Background:
- Differentiating classic calciphylaxis (CPX) from incidental cutaneous vascular calcification (CVC) is challenging.
- Establishing clear discriminative criteria for CPX is an ongoing clinical need.
Purpose of the Study:
- To identify clinicopathological features distinguishing classic CPX from CVC as an epiphenomenon.
- To evaluate the diagnostic utility of perieccrine calcification and pseudoxanthoma elasticum (PXE)-like changes in CPX.
Main Methods:
- Retrospective observational cohort study of 66 patients with CVC.
- Analysis of clinicopathological parameters, including lesion characteristics, laboratory findings, and histopathology.
- Evaluation of perieccrine calcification and PXE-like changes.
Main Results:
- The CPX group exhibited higher rates of renal failure, hypertension, painful lesions, and mortality.
- Histopathology revealed more affected vessels per field with subintimal concentric calcification and exclusive perieccrine calcification in the CPX group.
- PXE-like changes were more frequent in CPX but also present in the epiphenomenon group.
Conclusions:
- Perieccrine calcification and concentric calcification patterns in multiple vessels are potential diagnostic markers for CPX.
- PXE-like changes, while not exclusive, may suggest a diagnosis of CPX.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
