Differential Diagnosis & Pitfalls
- – yellowish papules, cobblestone plaques, and coarser wrinkling in sun-exposed areas
- Perifollicular elastolysis – white perifollicular papules with loss of elastic fibers limited to the perifollicular location
- – Term that encompasses white fibrous papulosis of the neck and PXE-like papillary dermal elastolysis. White or yellowish papules on the neck and torso display diminished elastin and fibrillin and/or thickened collagen bundles in the papillary and reticular dermis.
