Summary
Erythema annulare centrifugum (EAC) is a skin condition with annular plaques. This case details a 50-year history of recurrent EAC, the longest reported duration, highlighting its chronic and potentially seasonal nature.
Area of Science:
- Dermatology
- Clinical Case Studies
Background:
- Erythema annulare centrifugum (EAC) is a reactive gyrate erythema presenting as annular, erythematous plaques with trailing scale.
- The pathophysiology of EAC is not fully understood, and its inciting causes are diverse.
- The typical duration of EAC lesions is approximately 11 months.
Observation:
- A patient presented with a recurrent history of Erythema annulare centrifugum spanning 50 years.
- The patient's EAC exhibited a pattern of seasonal recurrence.
- No specific cause for the recurrent EAC was identified in this case.
Findings:
- This case represents the longest documented duration of recurrent Erythema annulare centrifugum.
- The prolonged and recurrent nature of EAC in this patient challenges the typical disease course.
- Seasonal recurrence patterns were observed, suggesting potential environmental or internal triggers.
Implications:
- This case underscores the potential for Erythema annulare centrifugum to follow a chronic, decades-long course.
- Further research into the pathophysiology and triggers of chronic EAC is warranted.
- Understanding long-term EAC presentations may aid in patient management and diagnosis.

01:05Centrifugation
Centrifugation is a separation technique based on differences in density or size. It is commonly used to separate solids from aqueous interferents. During centrifugation, the sample is placed in centrifugation tubes and spun at high angular velocity, which allows centrifugal force to act differentially on the different densities or masses of the components. After spinning, the supernatant liquid is decanted. Depending on the specific application, either the pellet or the supernatant is retained...
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...
01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

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...

01:27Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

01:23Rheumatic 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...
