Insights

Pseudoxanthoma elasticum (PXE) is a rare genetic disorder causing skin lesions in childhood. Early diagnosis and consistent follow-up are crucial for managing potential eye and heart complications, though standards are currently lacking.

Area of Science:

  • Dermatology
  • Medical Genetics
  • Metabolic Diseases

Background:

  • Pseudoxanthoma elasticum (PXE) is a rare, inherited metabolic disorder characterized by progressive calcification of elastic fibers.
  • It typically manifests in childhood with distinctive skin lesions, but can lead to severe systemic complications.

Observation:

  • Two female patients presented with yellowish, xanthoma-like papules on the neck during childhood.
  • Dermatological examination and subsequent skin biopsy confirmed the diagnosis of pseudoxanthoma elasticum.

Findings:

  • The diagnosis of PXE was established based on clinical presentation and histopathological findings.
  • PXE is a hereditary condition with early onset and characteristic cutaneous manifestations.

Implications:

  • Early identification of PXE is critical for timely intervention and management of potential ocular and cardiovascular complications.
  • The lack of established follow-up standards for PXE patients highlights a need for developing comprehensive care guidelines to prevent severe morbidity.

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
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...

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Chronic Obstructive Pulmonary Disease II: Emphysema

Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
