Summary
This report details a case of pseudoxanthoma elasticum (PXE) presenting with recurrent joint issues, alongside typical cardiac and gastrointestinal symptoms. Joint lesions histologically resembled subacute synovitis, suggesting a link to the underlying PXE condition.
Area of Science:
- Rheumatology
- Genetics
- Dermatology
Background:
- Pseudoxanthoma elasticum (PXE) is a rare genetic disorder affecting connective tissue, primarily the skin, eyes, and cardiovascular system.
- PXE is characterized by the progressive calcification and fragmentation of elastic fibers in various tissues.
- While cardiac and gastrointestinal manifestations are recognized, joint involvement in PXE is less commonly reported.
Purpose of the Study:
- To report a case of PXE with unusual recurrent joint manifestations.
- To investigate the histological features of the joint lesions in this PXE patient.
- To explore the potential link between PXE and joint pathology.
Main Methods:
- Case report of a patient diagnosed with PXE.
- Clinical evaluation including assessment of cardiac, gastrointestinal, and joint symptoms.
- Histopathological examination of joint tissue samples.
Main Results:
- The patient presented with cardiac and gastrointestinal symptoms typical of PXE.
- Recurrent joint manifestations were observed, suggesting a potential complication of PXE.
- Histological analysis of joint lesions revealed features consistent with subacute synovitis.
Conclusions:
- PXE can present with a broader spectrum of symptoms than previously recognized, including significant joint involvement.
- The joint lesions in PXE may histologically mimic inflammatory arthropathies like subacute synovitis.
- Further research is warranted to elucidate the mechanisms and prevalence of joint manifestations in PXE.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
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...
01:23Chronic 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.
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...

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:19Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations
Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...
