Insights

Congenital localized scleroderma (CLS) is a rare condition presenting at birth. This rare form of juvenile localized scleroderma (JLS) exclusively shows linear subtypes, often misdiagnosed, necessitating earlier identification.

Area of Science:

  • Pediatric Rheumatology
  • Pediatric Dermatology
  • Neonatology

Background:

  • Juvenile localized scleroderma (JLS) typically manifests in later childhood.
  • Congenital localized scleroderma (CLS) is a rare variant with onset at birth.
  • Understanding CLS is crucial for early diagnosis and management in neonates.

Observation:

  • A multinational study identified 6 cases (0.8%) of CLS among 750 JLS patients.
  • All CLS cases presented with linear scleroderma, four with facial 'en coup de sabre' morphology.
  • Misdiagnosis was common, with delays averaging 3.9 years.

Findings:

  • CLS exhibits a significantly longer disease duration at diagnosis compared to late-onset JLS.
  • The 'en coup de sabre' subtype was more frequent in CLS.
  • Linear scleroderma was the sole presentation in all studied CLS cases.

Implications:

  • CLS is likely underestimated in newborns and requires inclusion in differential diagnoses for infants with skin lesions.
  • Prompt diagnosis of CLS can prevent functional and aesthetic complications.
  • Early therapeutic intervention is vital for managing CLS and mitigating long-term sequelae.

Desmosomes01:05

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
Skin Cancer01:30

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...
Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
Cirrhosis I: Introduction01:23

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...
