Non‐invasive imaging of mid‐dermal elastolysis

Summary Mid‐dermal elastolysis (MDE) is a rare disease that is characterized histopathologically by selective loss of elastic tissue in the mid dermis. We aimed to assess MDE using noninvasive skin imaging techniques in vivo . We examined both the lesional and adjacent healthy skin of a woman with the reticular variant of MDE, using confocal scanning laser microscopy, optical coherence tomography (OCT) and high‐frequency ultrasound (HFUS). The median diameter of blood vessels at the top of dermal papillae was significantly increased in erythematous lesional skin compared with healthy skin. The mid‐dermal signal intensity detected by OCT was higher in healthy skin than in lesional skin. With HFUS, mid‐dermal density values were significantly higher in healthy skin than in lesional skin. Our preliminary findings indicate that noninvasive skin imaging methods such as OCT and HFUS might be suitable techniques for the evaluation and monitoring of elastolytic skin disorders such as MDE.
