Porphyria Cutanea Tarda
• Commonly presents as bullae on the dorsal surfaces of the hands and feet
• Sporadic form of PCT occurs in approximately 5% of patients on dialysis; this form is caused by increased uroporphyrin concentrations and can be triggered by ingestion of alcohol, estrogens or iron and by chronic infections such as hepatitis B, hepatitis C or HIV
• Treatment : Unsatisfactory

Nephrogenic systemic fibrosis in a 56-year-old patient.
(A)The typical red discoloration and orange-peel thickening
of the skin (peau d'orange) of the upper arm with a 'woody' texture.
(B) Secondary thrombosis of the arteriovenous fistula in the left arm (arrow) owing to progressive tightening of the skin.
(C) The patient's left hand is severely affected with limited
movement of the digital joints, which resulted in contractures.

Skin changes in Acute Renal Failure
• 1. Edema• 2. Uremic Frost
![Page 31: Skin in ckd Dr.chandan](https://reader035.vdocuments.mx/reader035/viewer/2022081413/546672d4b4af9f493f8b52e1/html5/thumbnails/31.jpg)
Uremic Frost
Was a frequent In the pre-dialysis era
The frost consists of a white or yellowish coating of urea crystals on the beard area and other parts of the face, neck and on the trunk.
It is due to eccrine deposition of urea crystals on the skin surface of patients with severe uremia
