Summary
Pseudoxanthoma elasticum (PXE) is a rare genetic disorder affecting elastic fibers. Early diagnosis and monitoring of cardiovascular and retinal complications are crucial for managing this incurable condition.
Area of Science:
- Genetics and rare diseases
- Dermatology
- Ophthalmology
- Cardiology
Background:
- Pseudoxanthoma elasticum (PXE) is a rare inherited disorder.
- Characterized by progressive mineralization and fragmentation of elastic fibers in the skin, retina, and cardiovascular system.
- Diagnosis relies on clinical signs, histology, and genetic testing.
Observation:
- This case report details a 12-year-old child.
- The child presented with painless, mildly itchy yellow papules on the neck over one year.
- These lesions are indicative of early-stage PXE skin manifestations.
Findings:
- The patient's presentation aligns with the typical initial dermatological signs of PXE.
- The case highlights the importance of recognizing subtle skin changes in pediatric patients.
- Prompt diagnosis is essential for initiating timely management strategies.
Implications:
- PXE is currently incurable, emphasizing the need for proactive management.
- Regular monitoring for cardiovascular and retinal complications is vital for a favorable prognosis.
- This case underscores the significance of early detection in improving patient outcomes for rare genetic disorders.

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...

01:11Papillary 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...

01:19Pigmentation
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...

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Skin 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...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
