ICD-10: A26.0

Clinical Description of Cutaneous Erysipeloid (ICD-10 Code A26.0)

Definition and Overview
Cutaneous erysipeloid is a skin infection primarily caused by the bacterium Erysipelothrix rhusiopathiae. This organism is commonly found in animals, particularly in swine, and can be transmitted to humans through direct contact with infected animals or contaminated animal products. The condition is characterized by localized skin lesions that resemble erysipelas, hence the name "erysipeloid."

Etiology
The causative agent, Erysipelothrix rhusiopathiae, is a gram-positive bacillus. It is often associated with occupations that involve handling animals, such as butchers, veterinarians, and farmers. The infection typically occurs after a break in the skin, allowing the bacteria to enter and cause localized inflammation.

Clinical Features

Symptoms
Patients with cutaneous erysipeloid may present with the following symptoms:
- Localized Erythema: A well-defined, raised, and red area of skin that may be warm to the touch.
- Swelling: The affected area often exhibits significant swelling.
- Pain and Tenderness: Patients may experience discomfort or pain in the affected region.
- Systemic Symptoms: In some cases, patients may also experience fever, chills, and malaise, although these are less common.

Lesion Characteristics
The lesions typically appear on the hands or fingers, particularly in individuals who work with animals. They may evolve from a small papule to a larger plaque and can sometimes develop vesicles or pustules. The lesions are often self-limiting but can persist for weeks if untreated.

Diagnosis

Clinical Diagnosis
Diagnosis of cutaneous erysipeloid is primarily clinical, based on the characteristic appearance of the lesions and the patient's occupational history. A history of exposure to animals or animal products can support the diagnosis.

Laboratory Tests
While laboratory confirmation is not always necessary, cultures from the lesion can be performed to identify Erysipelothrix rhusiopathiae. Serological tests may also be used, but they are less common.

Treatment

Antibiotic Therapy
The first-line treatment for cutaneous erysipeloid typically involves antibiotics. Commonly prescribed antibiotics include:
- Penicillin: Often the drug of choice due to its effectiveness against Erysipelothrix rhusiopathiae.
- Cephalosporins: May be used in patients with penicillin allergies.
- Tetracyclines: An alternative for those who cannot tolerate penicillin.

Supportive Care
In addition to antibiotics, supportive care may include analgesics for pain management and wound care to prevent secondary infections.

Prognosis

The prognosis for cutaneous erysipeloid is generally good, especially with prompt treatment. Most patients respond well to antibiotic therapy, and lesions typically resolve without complications. However, if left untreated, the infection can lead to more severe systemic illness, particularly in immunocompromised individuals.

Conclusion

ICD-10 code A26.0 for cutaneous erysipeloid encapsulates a specific skin infection caused by Erysipelothrix rhusiopathiae, characterized by localized erythema, swelling, and potential systemic symptoms. Understanding the clinical features, diagnostic methods, and treatment options is crucial for effective management and prevention of this occupationally related infection.

Cutaneous erysipeloid, classified under ICD-10 code A26.0, is a skin infection primarily caused by the bacterium Erysipelothrix rhusiopathiae. This organism is commonly associated with animal handling, particularly in occupations involving fish and livestock. Understanding the clinical presentation, signs, symptoms, and patient characteristics is crucial for effective diagnosis and management.

Clinical Presentation

Etiology

Cutaneous erysipeloid is typically caused by Erysipelothrix rhusiopathiae, which can enter the body through breaks in the skin. This bacterium is often found in animals, particularly in swine, and can be transmitted to humans through direct contact with infected animals or contaminated environments[1].

Signs and Symptoms

The clinical presentation of cutaneous erysipeloid can vary, but common signs and symptoms include:

• Localized Erythema: The initial sign is often a well-defined, raised, and erythematous lesion that may resemble erysipelas, hence the name. The lesion typically appears on the hands or fingers, where contact with the pathogen is most likely[1][2].

• Swelling and Induration: The affected area may become swollen and firm, indicating inflammation. This induration can be quite pronounced, leading to discomfort for the patient[2].

• Pain and Tenderness: Patients often report pain or tenderness in the affected area, which can be exacerbated by movement or pressure[1].

• Systemic Symptoms: In some cases, patients may experience mild systemic symptoms such as fever, malaise, or chills, although these are less common compared to localized symptoms[2].

• Duration and Resolution: The lesions can persist for several days to weeks, but they typically resolve with appropriate antibiotic treatment. Without treatment, the infection may lead to more severe complications, including systemic involvement[1][2].

Patient Characteristics

Risk Factors

Certain patient characteristics and risk factors are associated with cutaneous erysipeloid:

• Occupational Exposure: Individuals who work in agriculture, animal husbandry, or fisheries are at higher risk due to frequent contact with animals or contaminated environments[1][2].

• Immunocompromised Status: Patients with weakened immune systems, such as those with diabetes, chronic illnesses, or undergoing immunosuppressive therapy, may be more susceptible to infections, including cutaneous erysipeloid[2].

• Age and Gender: While cutaneous erysipeloid can affect individuals of any age, it is more commonly reported in adults, particularly males, likely due to occupational exposure patterns[1].

Diagnosis

Diagnosis is primarily clinical, based on the characteristic appearance of the lesions and the patient's history of exposure to potential sources of infection. Laboratory confirmation can be achieved through culture of the organism from the lesion, although this is not always necessary for treatment initiation[2].

Conclusion

Cutaneous erysipeloid, represented by ICD-10 code A26.0, is a localized skin infection with distinct clinical features. Recognizing the signs and symptoms, along with understanding patient characteristics and risk factors, is essential for timely diagnosis and management. Early intervention with appropriate antibiotics can lead to a favorable outcome, particularly in at-risk populations. Awareness of this condition is vital for healthcare providers, especially those working in fields with potential exposure to Erysipelothrix rhusiopathiae.
