Name of the Condition

• Cutaneous Amebiasis (ICD-10 Code: A06.7)

Summary

Cutaneous amebiasis is a rare skin infection caused by the parasite Entamoeba histolytica. It generally occurs when amebiasis, usually an intestinal infection, spreads to the skin, leading to ulcers and lesions.

Causes

The condition is caused by the protozoan parasite Entamoeba histolytica. It typically spreads through direct skin contact with infected fecal matter, often occurring in individuals with compromised immune systems or poor hygiene practices.

Risk Factors

• Residing in or traveling to regions with poor sanitation
• Compromised immune system (e.g., HIV/AIDS, cancer)
• Existing gastrointestinal amebic infection
• Poor hygiene and sanitation

Symptoms

• The presence of painful skin ulcers or lesions, often with a raised border
• Localized redness and swelling
• Possible discharge from lesions

Diagnosis

• Physical examination of skin lesions
• Microscopic examination of skin scrapings
• Biopsy of the lesion for histopathological study
• Serological tests to detect anti-amebic antibodies

Treatment Options

• Antimicrobial therapy: Metronidazole or tinidazole is commonly used to eliminate the parasite.
• Local wound care: Topical treatments and proper wound hygiene to promote healing.
• In severe cases, surgical intervention to debride necrotic tissue may be necessary.

Prognosis and Follow-Up

• With prompt and appropriate treatment, the condition can be resolved effectively.
• Regular follow-up with healthcare providers is important to monitor for potential recurrence or complications.

Complications

• Secondary bacterial infections of skin lesions
• Permanent skin scarring and disfigurement
• Potential systemic spread if untreated

Lifestyle & Prevention

• Maintain proper hygiene and sanitation, especially in environments with known infection risk.
• Avoid direct contact with contaminated fecal matter.
• Ensure safe food and water practices in high-risk areas.

When to Seek Professional Help

• Appearance of sudden, painful skin lesions, especially after travel to endemic areas
• Signs of infection, such as fever or increased redness and swelling around the ulcer

Tips for Medical Coders

• Ensure the code A06.7 is used specifically for cutaneous presentations of amebiasis.
• Distinguish from other types of amebiasis (intestinal, hepatic) to avoid miscoding.
• Consider coding additional complications if present, such as skin infections.
