Abstract:
Case 1 A 16‐year‐old Korean man presented with asymptomatic erythematous striae‐like bands on his back which had been present for 6 months and had migrated to his shoulder ( Fig. 1a ). He had no history of corticosteroid therapy, rapid gain or loss of weight, debilitating infection or illness. Histopathologically, fine, fragmented elastic fibers were shown in the dermis, but there were no clumped elastic fibers ( Fig. 2a ). Electron microscopy showed an irregular, fragmented, electron‐dense granular substance and a fragmented, electron‐lucent substance between the normal collagen fibers, and no microfibrils ( Fig. 3a ). This indicates the degeneration of elastic fibers.
