ICD-10: B88.1

Tungiasis, classified under ICD-10 code B88.1, refers to an infestation caused by the sand flea, specifically Tunga penetrans. This condition is primarily characterized by the penetration of the female sand flea into the skin, leading to a range of clinical manifestations.

Clinical Description of Tungiasis

Etiology

Tungiasis is caused by the sand flea, which is prevalent in tropical and subtropical regions, particularly in parts of Africa, Central and South America, and the Caribbean. The female sand flea burrows into the skin, typically on the feet, but can also affect other areas of the body. This infestation is often associated with poor sanitation and living conditions, as the fleas thrive in sandy environments.

Pathophysiology

Once the female sand flea penetrates the skin, it can cause a localized inflammatory response. The flea enlarges as it feeds on blood, leading to the formation of a small, painful nodule. The nodule may become necrotic, and secondary bacterial infections can occur due to scratching or irritation.

Clinical Features

The clinical presentation of tungiasis includes:

• Nodular Lesions: The most characteristic sign is the presence of small, itchy, and painful nodules at the site of infestation. These nodules may appear as dark spots, which are the embedded fleas.
• Inflammation: Surrounding tissue may become red and swollen due to the inflammatory response.
• Secondary Infections: Scratching the lesions can lead to bacterial infections, resulting in further complications such as abscess formation.
• Systemic Symptoms: In severe cases, especially in immunocompromised individuals, systemic symptoms such as fever and malaise may occur.

Diagnosis

Diagnosis is primarily clinical, based on the characteristic appearance of the lesions and the patient's history of exposure to endemic areas. In some cases, a biopsy may be performed to confirm the presence of the sand flea.

Treatment

Management of tungiasis involves:

• Removal of the Flea: The primary treatment is the careful extraction of the embedded flea, which can be done surgically or through other means.
• Symptomatic Relief: Pain relief and anti-inflammatory medications may be prescribed to alleviate discomfort.
• Antibiotics: If secondary bacterial infections are present, appropriate antibiotic therapy is necessary.

Prevention

Preventive measures include improving sanitation, wearing protective footwear, and avoiding contact with sandy areas known to harbor sand fleas.

Conclusion

ICD-10 code B88.1 for tungiasis highlights the importance of recognizing this condition, particularly in endemic regions. Understanding its clinical features, diagnosis, and treatment options is crucial for effective management and prevention of complications associated with this infestation. Awareness and education about the risks and preventive measures can significantly reduce the incidence of tungiasis in vulnerable populations.
