Additional Information
Description
Pityriasis lichenoides et varioliformis acuta (PLVA) is a rare skin condition characterized by an acute inflammatory response that leads to the development of papules and vesicles. This condition is classified under the ICD-10 code L41.0, which falls within the broader category of pityriasis lichenoides.
Clinical Description
Etiology and Pathophysiology
The exact cause of PLVA remains unclear, but it is believed to be related to an immune-mediated response, possibly triggered by infections, medications, or other environmental factors. The condition is often associated with viral infections, particularly Epstein-Barr virus (EBV) and cytomegalovirus (CMV) infections, which may play a role in its pathogenesis[3][4].
Symptoms and Clinical Features
PLVA typically presents with the following clinical features:
- Lesions: The condition is characterized by the sudden appearance of small, erythematous papules that can evolve into vesicles and crusted lesions. These lesions often resemble variola (smallpox) lesions, hence the name "varioliformis."
- Distribution: Lesions are commonly found on the trunk, upper arms, and legs, but they can appear anywhere on the body.
- Itching and Discomfort: Patients may experience pruritus (itching) associated with the lesions, although the intensity can vary.
- Duration: The acute phase of the disease can last from several weeks to a few months, and it may resolve spontaneously, although some cases can recur[2][5].
Diagnosis
Diagnosis of PLVA is primarily clinical, based on the characteristic appearance of the lesions. A skin biopsy may be performed to rule out other conditions, such as psoriasis or drug eruptions, and to confirm the diagnosis. Histological examination typically reveals a lichenoid tissue reaction pattern with interface dermatitis and a perivascular infiltrate[1][3].
Treatment Options
Management of PLVA focuses on alleviating symptoms and may include:
- Topical Corticosteroids: These are often the first line of treatment to reduce inflammation and itching.
- Systemic Corticosteroids: In more severe cases, systemic corticosteroids may be prescribed to control widespread lesions.
- Phototherapy: Ultraviolet light therapy can be beneficial for some patients.
- Antiviral Medications: If a viral infection is suspected to be a trigger, antiviral therapy may be considered[4][5].
Prognosis
The prognosis for patients with PLVA is generally favorable, with many experiencing complete resolution of lesions over time. However, some individuals may have recurrent episodes, and long-term follow-up may be necessary to monitor for any potential complications or recurrences[2][3].
In summary, Pityriasis lichenoides et varioliformis acuta (ICD-10 code L41.0) is a distinct dermatological condition characterized by acute inflammatory skin lesions. While the exact etiology remains uncertain, effective management strategies are available to alleviate symptoms and promote healing.
Clinical Information
Pityriasis lichenoides et varioliformis acuta (PLVA), classified under ICD-10 code L41.0, is a rare skin condition characterized by specific clinical presentations, signs, symptoms, and patient characteristics. Understanding these aspects is crucial for accurate diagnosis and management.
Clinical Presentation
PLVA typically presents as an acute eruption of papules and vesicles that can evolve into crusted lesions. The condition is often self-limiting but can be distressing for patients due to its appearance and associated symptoms.
Key Features:
- Eruption Type: The lesions usually start as small, erythematous papules that may progress to vesicles and then crusts. They can resemble varicella (chickenpox) lesions, hence the term "varioliformis" in the name.
- Distribution: Lesions are commonly found on the trunk, extremities, and sometimes the face. They may appear in crops, leading to a patchy distribution.
- Duration: The acute phase can last from a few weeks to several months, with spontaneous resolution often occurring.
Signs and Symptoms
Patients with PLVA may exhibit a range of signs and symptoms, which can vary in intensity:
Common Symptoms:
- Pruritus: Itching is a frequent complaint, which can be mild to severe.
- Pain or Tenderness: Some patients may experience discomfort in the affected areas.
- Systemic Symptoms: In some cases, patients may report mild systemic symptoms such as fever or malaise, particularly during the initial outbreak.
Physical Examination Findings:
- Papules and Vesicles: The hallmark of PLVA is the presence of small, dome-shaped papules that may develop into vesicles.
- Crusting: As lesions evolve, they may crust over, leading to potential secondary infections if scratched.
- Post-inflammatory Hyperpigmentation: After resolution, some patients may experience darkening of the skin in the affected areas.
Patient Characteristics
PLVA can affect individuals of any age, but certain demographic trends have been observed:
Typical Patient Profile:
- Age: Most commonly seen in children and young adults, though it can occur at any age.
- Gender: There is no significant gender predilection reported.
- Associated Conditions: PLVA may be associated with other conditions, such as viral infections or immunological disorders, although the exact etiology remains unclear.
Risk Factors:
- Environmental Triggers: Some patients report that the condition may be triggered by infections, medications, or exposure to certain environmental factors.
- Immune Response: The condition may reflect an abnormal immune response, as it has been linked to viral infections and other immunological factors.

Overview of Pityriasis Lichenoides et Varioliformis Acuta
PLVA is thought to be an inflammatory response, possibly triggered by infections, medications, or other environmental factors. The lesions typically resolve over weeks to months, but treatment may be necessary to alleviate symptoms and expedite healing.
Standard Treatment Approaches
1. Topical Treatments
-
Corticosteroids: Topical corticosteroids are often the first line of treatment for PLVA. They help reduce inflammation and itching. Potent corticosteroids may be prescribed for more severe cases, applied directly to the affected areas[1].
-
Calcineurin Inhibitors: Medications such as tacrolimus or pimecrolimus can be used as alternatives to corticosteroids, especially in sensitive areas or for patients who prefer to avoid steroids[2].
2. Systemic Treatments
-
Oral Corticosteroids: In cases where topical treatments are insufficient, systemic corticosteroids may be prescribed to control severe inflammation and symptoms. This approach is typically reserved for more extensive or resistant cases[3].
-
Antihistamines: Oral antihistamines can help manage itching and discomfort associated with the lesions, improving the patient's quality of life during flare-ups[4].
3. Phototherapy
- Ultraviolet (UV) Light Therapy: Phototherapy, particularly narrowband UVB therapy, can be effective in treating PLVA. This treatment helps reduce inflammation and promote healing of the skin lesions[5]. PUVA (psoralen plus UVA) therapy may also be considered in some cases, although it is less commonly used for PLVA compared to other conditions like psoriasis[6].
4. Supportive Care
-
Moisturizers: Regular use of emollients can help maintain skin hydration and reduce irritation. This is particularly important for patients experiencing dryness or scaling[7].
-
Patient Education: Educating patients about the nature of the condition, its self-limiting nature, and the importance of adhering to treatment can help alleviate anxiety and improve compliance[8].
Conclusion
While Pityriasis lichenoides et varioliformis acuta is often self-limiting, various treatment options are available to manage symptoms and promote healing. Topical corticosteroids and calcineurin inhibitors are commonly used, with systemic corticosteroids reserved for more severe cases. Phototherapy can also be beneficial, particularly for extensive lesions. Supportive care, including moisturizers and patient education, plays a crucial role in the overall management of this condition. As always, treatment should be tailored to the individual patient's needs and response to therapy.
For any specific treatment plan, it is essential for patients to consult with a healthcare provider or dermatologist to determine the most appropriate approach based on their unique circumstances.
