... and hyperkeratosis together with subsiding inflammatory changes. However, orcein staining demonstrated that even after etretinate treatment, elastic fibers were still absent in the upper dermis with only few fibers being detectable in some specimens. Conventional electron microscopy and immunoelectron microscopy...

... and elastic fibers. No intracellular calcification was found. A flower-like arrangement of pleomorphic crystals was found around single collagen fibrils resembling the calcification of collagen seen in bone tissue. The elastic fibers showed a different pattern of calcification compared with other diseases...

... redundant skin folds were noted in the anterior axillary line and lower buttocks. By light and electron microscopy, involved and uninvolved skin demonstrated ‘lumpy-bumpy’ dermal elastic fibers with no calcium deposition. These histologic changes are similar to those previously described in patients...

...Cécile Bécuwe; Stéphane Dalle; Sandra Ronger-Savlé; François Skowron; Brigitte Balme; Jean Kanitakis; Luc Thomas Background: Elastosis perforans serpiginosa (EPS) is a reactive perforating dermatosis characterized by the elimination of abnormal elastic fibers from the upper dermis through...

... homogenization with decreased and fragmented elastic fibers. The clinical differential diagnosis includes papular acne scars, dermatofibrosis lenticularis disseminata (Buschke-Ollendorff syndrome), cutaneous collagenoma and nevus anelasticus, but histology clearly separates papular elastorrhexis from the other...

... of the epidermis for 2 weeks and the results were compared with those of nontreated skin explants. Dermal repair was analyzed histologically with quantification of collagen and elastic fibers, and biochemically by the measure of newly synthesized collagen as shown by adding tritiated proline to the culture medium...
