Elastin is Responsible for Tissue Elasticity01:12

Elastin 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...

Members Made of Elastoplastic Material

The behavior of elastoplastic materials under bending stresses, particularly in structural members with rectangular cross-sections, is crucial for predicting material responses and understanding failure modes. Initially, when a bending moment is applied, the stress distribution across the section follows Hooke's Law and is linear and elastic. This distribution means the stress increases from the neutral axis to the maximum at the outer fibers, up to the elastic limit.
As the bending moment...
Chronic Inflammation: Introduction01:12

Chronic 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...
Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. 
Anchoring junctions mechanically attach a cell to the...

Area of Science:

  • Dermatology
  • Histopathology
  • Connective tissue diseases

Background:

  • Linear focal elastosis (LFE) is a rare, benign skin condition.
  • It typically presents as asymptomatic, palpable yellow lines, often on the trunk.
  • Differential diagnosis includes striae and other elastotic disorders.

Purpose of the Study:

  • To report a case of linear focal elastosis in a young male.
  • To describe the clinical presentation and histopathological findings.
  • To contribute to the understanding of this uncommon dermatosis.

Main Methods:

  • Clinical examination of a 19-year-old male with asymptomatic yellow lines and axillary striae.
  • Light microscopic examination of skin biopsy.
  • Elastic tissue staining (e.g., Verhoeff-Van Gieson) to evaluate dermal elastic fibers.

Main Results:

  • The patient presented with characteristic asymptomatic, palpable yellow lines on the back.
  • Histopathology revealed dermal thickening without epidermal changes.
  • Elastic tissue stains demonstrated fragmented elastic fibers diffusely throughout the dermis.

Conclusions:

  • This case highlights the typical clinical and histopathological features of linear focal elastosis.
  • Fragmented elastic fibers are a key diagnostic finding.
  • Early recognition and histopathological confirmation are crucial for accurate diagnosis of LFE.
