Acute pityriasis lichenoides is a skin condition that can cause discomfort and distress. In this article, we’ll break down what acute pityriasis lichenoides is, its different types, the possible causes, symptoms to look out for, how it’s diagnosed, and the available treatment options. We’ll also explore some commonly prescribed medications. Our aim is to provide you with clear and easy-to-understand information about this skin disorder.
Types of Acute Pityriasis Lichenoides:
- Classic APL: Classic APL is the more common and less severe form of the condition. It typically presents with small, red or brownish spots on the skin. These spots can be itchy but are usually not painful. Classic APL often resolves on its own within weeks to months.
- Febrile Ulceronecrotic Mucha-Habermann Disease (FUMHD): FUMHD is a rare and severe variant of APL. In addition to the characteristic skin lesions, FUMHD can cause high fever and the development of painful ulcerations and necrotic lesions on the skin. This form of APL requires prompt medical attention and aggressive treatment.
Types of Acute Pityriasis Lichenoides:
- Pityriasis Lichenoides et Varioliformis Acuta (PLEVA): This is the most common type of acute pityriasis lichenoides. It is characterized by red or brown spots on the skin that can become pimple-like or blistered.
- Pityriasis Lichenoides Chronica (PLC): PLC is a less severe and more chronic form of the condition. It is marked by scaly, reddish-brown patches that can persist for months or even years.
Causes of Acute Pityriasis Lichenoides:
The exact cause of acute pityriasis lichenoides remains uncertain, but several factors may contribute to its development. These factors can include:
- Viral Infections: Some experts believe that certain viral infections may trigger acute pityriasis lichenoides, although this link is not well-established.
- Immune System Dysfunction: An overactive or weakened immune system may play a role in the development of this skin condition.
- Genetics: There may be a genetic predisposition, as acute pityriasis lichenoides can run in families.
- Stress: Stress and emotional factors might exacerbate the condition in some individuals.
- Medications: Some medications have been associated with the onset of acute pityriasis lichenoides as a rare side effect.
- Environmental Factors: Exposure to certain environmental triggers may contribute to the development of the condition in susceptible individuals.
- Inflammatory Processes: Inflammation within the body may play a role in the development of skin lesions associated with acute pityriasis lichenoides.
- Infectious Agents: Some researchers have suggested that bacterial or fungal infections could potentially be linked to the condition, although this remains a subject of study.
- Autoimmune Factors: There is ongoing research exploring the possibility of autoimmune factors contributing to the development of acute pityriasis lichenoides.
- Nutritional Factors: Nutritional deficiencies or imbalances might influence the development or severity of the condition.
- Hormonal Changes: Hormonal fluctuations, especially during puberty, pregnancy, or menopause, could potentially be linked to acute pityriasis lichenoides in some cases.
- Allergies: Allergic reactions or sensitivities to certain substances could be a contributing factor for some individuals.

- Insect Bites: There have been rare reports of insect bites potentially triggering or exacerbating the condition.
- Chemical Exposures: Exposure to certain chemicals or irritants may play a role in the development of skin lesions.
- Autoinflammatory Disorders: Some rare autoinflammatory disorders may be associated with acute pityriasis lichenoides.
- Gastrointestinal Issues: Digestive problems have been suggested as a possible contributing factor in some cases.
- Endocrine Disorders: Disorders of the endocrine system, such as thyroid dysfunction, might be linked to the development of the condition.
- Environmental Factors: Exposure to environmental toxins or pollutants could potentially contribute to skin issues.
- Unknown Factors: In many cases, the cause of acute pityriasis lichenoides remains unknown, and further research is needed to understand its origins fully.

- Changes in Skin Color: After the lesions heal, the affected skin may temporarily be lighter or darker in color than the surrounding skin.
- Nail Changes: Rarely, changes to the nails, such as pitting or ridges, may occur in association with the skin condition.
Diagnostic Tests for Acute Pityriasis Lichenoides:
Diagnosing acute pityriasis lichenoides typically involves a combination of clinical evaluation and tests. Common diagnostic approaches include:
- Physical Examination: A dermatologist will visually inspect the skin lesions and inquire about your medical history and symptoms.
- Skin Biopsy: A small sample of skin may be taken for examination under a microscope to confirm the diagnosis.
- Blood Tests: Blood tests may be conducted to rule out other potential causes and to assess for any underlying medical conditions.
- Patch Testing: In cases where allergic reactions are suspected, patch testing may be performed to identify specific triggers.
- Skin Scraping: Scraping the skin surface to check for fungal or bacterial infections.
- Cultures: In cases where infection is suspected, cultures of skin samples may be performed.
- Imaging: In rare cases with severe symptoms, imaging studies such as X-rays or CT scans may be used to assess internal involvement.
- Differential Diagnosis: The doctor may rule out other skin conditions that resemble acute pityriasis lichenoides, such as psoriasis, eczema, or fungal infections.
- Skin Allergy Testing: If allergies are suspected as a trigger, allergy testing may be considered.
- Immunological Tests: Blood tests assessing immune system function may be conducted.
- PCR Testing: Polymerase chain reaction (PCR) testing may be used to identify viral or bacterial DNA in skin samples.
- Skin Culture: Culturing the skin lesions to check for the presence of infectious agents.
- Skin Swab: Swabbing the skin to collect samples for laboratory analysis.
- Skin Histopathology: Examination of skin tissue under a microscope to assess the extent of inflammation and other characteristics.
