Tinea imbricata, classified under ICD-10 code B35.5, is a specific type of dermatophytosis, which refers to fungal infections of the skin. This condition is characterized by its distinct clinical presentation and etiology, primarily caused by the dermatophyte fungus Trichophyton concentricum.

Clinical Description

Etiology

Tinea imbricata is predominantly caused by Trichophyton concentricum, a fungus that thrives in warm, humid environments. This condition is most commonly found in tropical and subtropical regions, particularly in areas with high humidity and temperatures, which facilitate fungal growth and transmission[1][2].

Symptoms and Signs

The clinical manifestations of tinea imbricata include:

• Appearance: The infection typically presents as concentric, ring-like lesions on the skin, often with a scaly or crusted surface. These lesions can vary in color, ranging from brown to reddish-brown, and may have a raised border[1].
• Location: Commonly affected areas include the trunk, arms, and legs, but it can also appear on the scalp and other body parts[2].
• Itching: Patients may experience pruritus (itching), which can vary in intensity. The itching is often exacerbated by sweating or heat[1].
• Scaling: The lesions are usually scaly, and the scales may be more pronounced at the edges of the lesions, giving them a characteristic appearance[2].

Diagnosis

Diagnosis of tinea imbricata is primarily clinical, based on the characteristic appearance of the lesions. However, laboratory confirmation can be achieved through:

• KOH Examination: A potassium hydroxide (KOH) preparation of skin scrapings can reveal fungal hyphae and spores under a microscope.
• Culture: Fungal cultures can be performed to identify the specific dermatophyte responsible for the infection, although this is less commonly done in practice[1][2].

Treatment

The management of tinea imbricata typically involves antifungal therapy, which may include:

• Topical Antifungals: Agents such as clotrimazole or terbinafine are often effective for localized infections.
• Oral Antifungals: In more extensive or resistant cases, systemic treatment with oral antifungals like griseofulvin or itraconazole may be necessary[1][2].

Prevention

Preventive measures focus on reducing exposure to the fungus, particularly in endemic areas. This includes maintaining good hygiene, avoiding sharing personal items, and wearing breathable clothing to minimize moisture accumulation on the skin[2].

Conclusion

Tinea imbricata, represented by ICD-10 code B35.5, is a dermatophyte infection characterized by its unique ring-like lesions and is primarily caused by Trichophyton concentricum. Understanding its clinical features, diagnostic methods, and treatment options is essential for effective management and prevention of this fungal skin condition. For individuals living in or traveling to endemic regions, awareness and preventive strategies are crucial to mitigate the risk of infection.

Tinea imbricata, classified under ICD-10 code B35.5, is a superficial fungal infection primarily caused by dermatophytes, particularly Trichophyton concentricum. This condition is characterized by specific clinical presentations, signs, symptoms, and patient characteristics that are essential for diagnosis and management.

Clinical Presentation

Tinea imbricata typically manifests as a chronic skin condition, often affecting the trunk, limbs, and sometimes the scalp. The infection is more prevalent in tropical and subtropical regions, particularly in areas with high humidity and warmth, which favor fungal growth.

Signs and Symptoms

1. Skin Lesions:
   - The hallmark of tinea imbricata is the presence of concentric rings or "target" lesions that may appear scaly and erythematous. These lesions can vary in size and often have a raised border.
   - Lesions may exhibit a characteristic "imbricated" or overlapping appearance, which is where the name "imbricata" originates.

2. Itching and Discomfort:
   - Patients often report pruritus (itching) in the affected areas, which can lead to scratching and secondary infections.

3. Scaling:
   - The lesions are typically scaly, and the scales may be fine or thick, depending on the chronicity of the infection.

4. Hair Involvement:
   - In some cases, tinea imbricata can affect the scalp, leading to hair loss or broken hair shafts, although this is less common compared to other forms of tinea.

5. Secondary Infections:
   - Due to scratching, there is a risk of secondary bacterial infections, which can complicate the clinical picture.

Patient Characteristics

1. Demographics:
   - Tinea imbricata is more commonly seen in individuals living in tropical climates, particularly in regions such as Southeast Asia, the Pacific Islands, and parts of South America.
   - It can affect individuals of any age but is often seen in children and young adults.

2. Environmental Factors:
   - Patients who engage in activities that expose them to warm, humid environments are at higher risk. This includes individuals involved in outdoor sports or those living in densely populated areas with poor sanitation.

3. Immunocompetence:
   - While tinea imbricata can occur in immunocompetent individuals, those with compromised immune systems may experience more severe or widespread infections.

4. Personal Hygiene:
   - Poor personal hygiene and close contact with infected individuals or contaminated surfaces can increase the risk of transmission.

Conclusion

Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with tinea imbricata (ICD-10 code B35.5) is crucial for effective diagnosis and treatment. The concentric ring-like lesions, associated itching, and demographic factors play significant roles in identifying this condition. Early recognition and appropriate antifungal treatment can help manage symptoms and prevent complications, such as secondary infections. If you suspect tinea imbricata, consulting a healthcare professional for accurate diagnosis and management is essential.

Tinea imbricata, classified under ICD-10 code B35.5, is a dermatophyte infection characterized by a specific pattern of skin lesions. The diagnosis of tinea imbricata involves several criteria, which can be categorized into clinical evaluation, laboratory tests, and patient history.

Clinical Evaluation

1. Characteristic Lesions:
   - Tinea imbricata typically presents with annular (ring-shaped) lesions that may have a scaly border. These lesions often overlap and can appear in a "target" or "imbricated" pattern, which is distinctive for this condition[1].
   - The lesions are usually found on the trunk and extremities, and they may be itchy or asymptomatic[1].

2. Distribution:
   - The condition is more prevalent in tropical and subtropical regions, often affecting individuals with prolonged exposure to warm, humid environments[1][2].

Laboratory Tests

1. KOH Examination:
   - A potassium hydroxide (KOH) preparation of skin scrapings can be performed to identify fungal elements. The presence of hyphae and spores under microscopic examination supports the diagnosis of tinea imbricata[2][3].

2. Fungal Culture:
   - Culturing the skin scrapings on appropriate media can help confirm the diagnosis by isolating the causative dermatophyte, typically Trichophyton concentricum, which is specifically associated with tinea imbricata[2][3].

3. Histopathological Examination:
   - In some cases, a biopsy may be performed to examine the skin lesions histologically, which can reveal fungal elements and inflammatory changes consistent with dermatophyte infections[3].

Patient History

1. Exposure History:
   - A thorough history should include any known exposure to infected individuals or environments, as tinea imbricata is often transmitted through direct contact or shared surfaces[2][3].

2. Previous Dermatological Conditions:
   - Understanding the patient's history of skin conditions or previous fungal infections can provide context for the current diagnosis and help rule out other dermatological issues[3].

Conclusion

The diagnosis of tinea imbricata (ICD-10 code B35.5) relies on a combination of clinical observation, laboratory testing, and patient history. The characteristic appearance of the lesions, supported by KOH examination and culture, is crucial for accurate diagnosis. If you suspect tinea imbricata, it is advisable to consult a healthcare professional for a comprehensive evaluation and appropriate management.

Tinea imbricata, classified under ICD-10 code B35.5, is a superficial fungal infection primarily caused by the dermatophyte Trichophyton concentricum. This condition is characterized by scaly, ring-like lesions that can appear on various parts of the body, particularly in tropical and subtropical regions. The treatment for tinea imbricata typically involves antifungal medications and supportive care. Below is a detailed overview of standard treatment approaches.

Antifungal Medications

Topical Antifungals

For mild cases of tinea imbricata, topical antifungal agents are often the first line of treatment. Commonly used topical medications include:

• Clotrimazole: An imidazole antifungal that disrupts the fungal cell membrane.
• Miconazole: Another imidazole that is effective against dermatophytes.
• Terbinafine: An allylamine antifungal that inhibits squalene epoxidase, leading to fungal cell death.

These medications are typically applied directly to the affected areas once or twice daily for several weeks, depending on the severity of the infection[1][2].

Systemic Antifungals

In cases where the infection is extensive or does not respond to topical treatments, systemic antifungal therapy may be necessary. Common systemic agents include:

• Griseofulvin: This oral antifungal is effective for dermatophyte infections and is often used for tinea imbricata, especially in cases that are widespread or recurrent.
• Itraconazole: A triazole antifungal that can be used for more severe or resistant cases.
• Terbinafine: In oral form, it is also effective for treating dermatophyte infections and may be prescribed for tinea imbricata.

The duration of systemic treatment can vary but typically lasts from several weeks to a few months, depending on the clinical response and the extent of the infection[3][4].

Supportive Care

Hygiene and Skin Care

Maintaining good hygiene is crucial in managing tinea imbricata. Patients are advised to:

• Keep the affected areas clean and dry.
• Avoid tight clothing that can trap moisture.
• Use antifungal powders to reduce moisture in skin folds.

Monitoring and Follow-Up

Regular follow-up appointments are important to monitor the effectiveness of the treatment and to make adjustments if necessary. If there is no improvement after a few weeks of treatment, further evaluation may be needed to rule out other conditions or to consider alternative therapies[5].

Conclusion

Tinea imbricata, while often manageable with appropriate antifungal therapy, requires a tailored approach based on the severity of the infection and the patient's overall health. Topical treatments are effective for localized infections, while systemic medications are reserved for more extensive cases. Good hygiene practices and regular follow-up are essential components of successful management. If symptoms persist or worsen, consulting a healthcare professional for further evaluation is recommended.
