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.

01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...

01:09Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
