Loss of elastic tissue:
| • | Anetoderma (focal elastolysis) |
| • | Cutis laxa (generalized elastolysis) |
| • | granulomatous slack skin |
Elastic tissue disorders:
| • | Actinic granuloma (elastoclasis) |
| • | PXE* (generalized elastorrhexis with calcification) |
| • | Buschke-Ollendorf syndrome* (collagenomas with osteopoikilosis) |
| • | Marfan syndrome (fibrillin elastic fibers are composed of an elastin core wrapped by microfibrils (which are composed of fibrillin))** |
| • | Elastosis Perforans Serpiginosa |
*PXE and Buschke-Ollendorf lesions may look similar clinically
**Marfan affects skin, eyes, and cardiovascular system (like PXE)
Other:
erythema ab igne: histology = increased elastic fibers (but different from solar elastosis because seen only with elastic stain, not with H&E)
