Obsolete Synonym for Streptococcal Erysipelas

Streptococcal erysipelas, also known as chronic recurrent streptococcal erysipelas, is an outdated term used to describe a specific type of bacterial skin infection. This condition was previously characterized by its recurring nature and association with streptococcal bacteria.

Key Features:

• Recurring episodes of skin inflammation
• Association with streptococcal bacteria (group A or B)
• Typically affects the superficial dermis and lymphatic vessels

Note: The term "obsolete synonym" indicates that this name is no longer used in modern medical practice, and the condition is now referred to by other names.

Erysipelas: A Form of Cellulitis

Erysipelas is a form of cellulitis with marked superficial inflammation, typically affecting the lower limbs and the face [1]. The condition is characterized by its distinctive signs and symptoms.

Key Signs and Symptoms:

• Well-demarcated red edge: Erysipelas has a more well-defined border than cellulitis, making it easier to distinguish [2].
• Oedema: Swelling of the affected area is common in erysipelas.
• Hot and tender to touch: The skin may feel warm or hot to the touch, and can be painful when pressed.
• Fever: A fever may accompany erysipelas, although it's usually mild [3].
• Systemic manifestations: In some cases, systemic symptoms such as fever, tachycardia, confusion, hypotension, and leukocytosis may occur hours before the onset of local signs [4].

Other Possible Symptoms:

• Painful lameness: Erysipelas can cause pain and swelling in the affected limb.
• Rash and blisters: The condition can lead to the formation of blisters and sores (erysipelas lesions) on the skin.

It's essential to note that erysipelas is a curable condition, and symptoms often disappear within a few days of starting treatment [11]. However, the skin infection itself may take weeks to clear up.

Diagnostic Tests for Streptococcal Erysipelas

Streptococcal erysipelas, a type of skin infection caused by Group A Streptococcus (GAS), can be diagnosed using various tests. While some diagnostic methods have become obsolete, others remain relevant in confirming the diagnosis.

• Cytology: Cytological examination is particularly effective in identifying GAS in skin lesions [3]. This test involves examining cells from a skin sample under a microscope.
• Bacterial Culture: Bacterial culture remains a gold standard for diagnosing streptococcal infections, including erysipelas. A swab or biopsy sample can be cultured to confirm the presence of GAS [4].
• Molecular Diagnostic Tests: Molecular tests, such as PCR (Polymerase Chain Reaction), can also be used to diagnose streptococcal infections by detecting specific genetic material from the bacteria [3].

Obsolete Diagnostic Methods

Some diagnostic methods for streptococcal erysipelas have become obsolete due to advancements in technology and testing techniques. These include:

• CAMP Test: The CAMP test, which was once used to detect Group B Streptococcus (GBS), is no longer a recommended method for diagnosing streptococcal infections [2].
• Duplex Scan: Duplex scans were previously used as a diagnostic tool for confirming the diagnosis of streptococcal infections. However, this test has become obsolete with advancements in other testing techniques [6].
