Intracellular elastin in generalized granuloma annulare.
Journal of the American Academy of Dermatology
|June 1, 1986
Summary
Intracellular elastin particles were identified in generalized granuloma annulare and related conditions. These findings offer insights into the pathogenesis of granuloma annulare and associated elastotic disorders.
Area of Science:
- Dermatopathology
- Histology
- Electron Microscopy
Background:
- Granuloma annulare is a benign inflammatory skin condition.
- The exact pathogenesis of granuloma annulare remains incompletely understood.
- Elastin abnormalities have been implicated in various dermatoses.
Purpose of the Study:
- To review cases of generalized granuloma annulare.
- To describe the ultrastructural features of intracellular elastin particles.
- To investigate the presence of these particles in other granulomatous and elastotic conditions.
Main Methods:
- Review of thirteen cases of generalized granuloma annulare.
- Light and electron microscopic examination of skin biopsies.
- Comparative analysis of intracellular elastin particle presence across different diagnoses.
Main Results:
- Intracellular elastin particles were observed in eleven of thirteen generalized granuloma annulare cases.
- These bodies were also present in deep granuloma annulare and elastosis perforans serpiginosa.
- A small percentage of localized granuloma annulare cases showed these particles.
- Necrobiosis lipoidica did not exhibit intracellular elastin particles.
Conclusions:
- Intracellular elastin particles are a notable feature in generalized granuloma annulare.
- The presence of these particles may indicate a shared pathomechanism in certain granulomatous and elastotic skin diseases.
- Further research is warranted to elucidate the role of elastin in granuloma annulare.

01:42The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.Composition of the Extracellular MatrixThe extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse molecules.

01:12Elastin is Responsible for Tissue Elasticity
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

01:26Extracellular Matrix
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...
01:17Connective Tissue Fibers and Ground Substance
One of the significant functions of connective tissue is connecting tissues and organs. Unlike epithelial tissue that is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. It plays a significant role in the functioning of this tissue. The major component of the matrix is a...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
