The viscoelastic properties were significantly influenced by aging. Also, significant regional variations in the viscoelastic properties were observed. Skin elasticity measurement is useful for the quantitative evaluation of age-related changes.

This study shows that the Mexameter, an objective pigment-measuring device, can be used to achieve a more accurate diagnosis of hypopigmentary disorders, and that the relative melanin index (RMI), which represents the relative pigment levels, might be a more effective parameter than the melanin index (MI) itself for comparing pigmentation differences.

A subepidermal calcified nodule (SCN) is an uncommon form of calcinosis cutis that is not associated with other dermatologic or systemic illnesses. Clinically, SCN presents as a solitary, firm tumor that can be white, white-yellow, or erythematous. Most SCNs occur in children; they are extremely rare in adults. The treatment of choice is believed to be surgical excision. We describe a case of SCN on the right ear lobe of a 33-year-old male, which was treated using a CO2 laser and electrodessication.
