Background/aims: Anetoderma is a rare disease characterized by a prominent dermal atrophy with loss of elastic tissue. The aim of the study was to evaluate the rheological properties of anetoderma using a non‐invasive in vivo suction method. Methods: The Cutometer SM 474 was used with a 2‐ mm probe and successive 500 mbar load cycles. Skin thickness was measured using a 20 MHz ultrasonography A mode scanner. Results: Skin of anetoderma is thinner than normal. Cutaneous extensibility is markedly increased. The viscous component predominates when the anetoderma skin is not yet unfolded. After preconditioning, the defect in elasticity is uncovered. Conclusions: As expected, the rheological properties of anetoderma are abnormal. The nature of the changes varies according to the absence or presence of preconditioning.
