Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Skin 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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Peripheral 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...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Summary

Erythroderma, a rare skin condition, is often linked to pre-existing dermatoses like psoriasis, with skin biopsies crucial for diagnosis. Close follow-up is recommended due to potential relapses, especially in idiopathic cases.

Area of Science:

Dermatology
Internal Medicine

Background:

Erythroderma is a rare and poorly understood skin disorder with limited research on its causes and prognosis.
Understanding the etiology and evolution of erythroderma is essential for effective patient management.

Purpose of the Study:

To investigate the clinical characteristics, causes, and outcomes of 260 patients with erythroderma over an 11-year period.
To analyze clinical-histological correlations and describe survival rates for specific erythroderma etiologies.

Main Methods:

Retrospective review of clinical, laboratory, and biopsy data from 260 erythroderma patients treated between 2001 and 2012.
Epidemiological, clinical, biological, and histological data were recorded, along with treatments and outcomes.
Kaplan-Meier estimates were used to analyze overall and relapse-free survival for select etiologies.

Main Results:

The most common causes of erythroderma were pre-existing dermatoses (70.77%), primarily psoriasis (55%), followed by idiopathic causes (14.23%) and drug reactions (12.69%).
Carbamazepine was the most frequent drug implicated, and Chinese traditional herbal medicines were also identified as causes.
Pruritus, fever, and edema were dominant clinical findings; skin biopsies confirmed the cause in 55.56% of cases.
A 31.2% relapse rate was observed, with idiopathic erythroderma showing a higher incidence. Four of five deaths were directly attributed to erythroderma.

Conclusions:

Clinical features of erythroderma are often non-specific, making diagnosis challenging without skin biopsy.
The study highlights a high prevalence of erythroderma secondary to pre-existing dermatoses and a low rate of malignancy-associated cases.
Repeated evaluations, close patient follow-up, and skin biopsies are crucial for managing erythroderma effectively.
