Causes and Triggers
Understanding the causes and triggers of erythema multiforme (EM) and Stevens-Johnson syndrome (SJS) is crucial for identifying and managing these skin conditions. While both conditions may present similar symptoms, it is important to differentiate between them based on their underlying causes.
Erythema Multiforme (EM) Causes:
- EM is often triggered by infections, particularly herpes simplex virus (HSV) and mycoplasma pneumoniae.
- Other common causes include bacterial infections, medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and antibiotics, and certain malignancies.
- Additionally, exposure to certain allergens and radiation therapy can also result in EM.
SJS Causes:
- SJS, on the other hand, is primarily caused by an adverse drug reaction. Certain medications, such as antibiotics, anticonvulsants, and nonsteroidal anti-inflammatory drugs (NSAIDs), have been associated with SJS.
- Furthermore, infection with certain viruses, including human herpesvirus 6 and Epstein-Barr virus, has been linked to the development of SJS.
- Genetic factors may also play a role in increasing the susceptibility to SJS in some individuals.
Triggers:
Both EM and SJS can be triggered by various factors, including:
- Medications such as sulfonamides, allopurinol, and nevirapine.
- Viral infections such as herpes simplex virus or other respiratory infections.
- Bacterial infections like streptococcal infections.
- Immunizations like vaccines.
- Allergic reactions to certain foods, insect stings, or other allergens.
- Exposure to toxins or chemical substances.
Identifying these triggers is essential to prevent the recurrence of symptoms and manage the conditions effectively.
Diagnosis and Medical Interventions
In order to accurately diagnose erythema multiforme (EM) and Stevens-Johnson syndrome (SJS), dermatologists rely on a combination of clinical evaluation, patient history, and diagnostic tests. This comprehensive approach helps to differentiate between these two skin conditions.
Diagnosis of Erythema Multiforme (EM)
When assessing a patient suspected of having EM, dermatologists carefully examine the characteristic skin lesions. These erythematous target-like lesions, which often affect the extremities and mucous membranes, play a vital role in diagnosis. Additionally, healthcare providers consider the medical history and any known triggers, such as recent infections or medications.
To further confirm the diagnosis of EM, dermatologists may conduct skin biopsies or perform blood tests to rule out other possible causes. A biopsy can provide insights into the inflammatory response present in the lesions, while blood tests can help identify any underlying infections or autoimmune factors.
Diagnosis of Stevens-Johnson Syndrome (SJS)
The diagnosis of SJS involves a thorough examination of the characteristic skin and mucosal manifestations. Dermatologists observe widespread blistering and detachment of the skin, along with involvement of the mucous membranes, particularly the oral and ocular areas. This is essential for distinguishing SJS from other skin conditions.
In addition to the physical examination, medical professionals take into account the patient’s medical history, including any recent medication use or known triggers. This helps identify potential causes of the condition. To confirm the diagnosis, dermatologists may order skin biopsies, which can reveal the characteristic inflammatory pattern associated with SJS.
Medical Interventions and Treatment
Once a diagnosis of EM or SJS is established, prompt medical intervention is crucial. The treatment approach depends on the severity of the condition and may involve a multidisciplinary care team, including dermatologists, ophthalmologists, and specialists in supportive care.
The main goals of treatment for both EM and SJS are:
- Providing supportive care to manage symptoms and prevent complications
- Identifying and discontinuing any medications or triggers that may have caused or exacerbated the condition
- Preventing secondary infections
- Monitoring and managing potential systemic complications
Treatment options may include:
- Topical therapies to alleviate discomfort and promote healing
- Systemic medications, such as corticosteroids or immunosuppressants, to reduce inflammation
- Intravenous immunoglobulins to modulate the immune response
- Artificial tears and lubricating ointments for ocular involvement
- In severe cases, hospitalization in specialized burn units may be necessary
A multidisciplinary approach is essential in managing the potential complications associated with these conditions. Regular follow-up visits with healthcare providers are important for monitoring progress, adjusting treatment plans, and ensuring optimal patient care.

| Immune-mediated response | Immune-mediated response |
| Topical therapies, systemic medications, and supportive care | Topical therapies, systemic medications, and multidisciplinary care |
Treatment Approaches for EM and SJS
When it comes to managing erythema multiforme (EM) and Stevens-Johnson syndrome (SJS), dermatologists employ various treatment approaches based on the severity of the condition, the individual’s health status, and other factors.
Treatment for Erythema Multiforme (EM)
The treatment of erythema multiforme focuses on alleviating symptoms, promoting healing, and preventing recurrences. Mild cases of EM may only require symptomatic relief, such as topical corticosteroids or antihistamines to reduce itching and inflammation. In more severe cases, systemic corticosteroids or immunosuppressive medications may be prescribed to suppress the immune response and reduce the severity of the rash.
Patients with recurrent EM episodes may benefit from long-term therapy with antiviral medications, particularly if the condition is triggered by viral infections. Dermatologists may also recommend prophylactic therapy to prevent future flare-ups.
Treatment for Stevens-Johnson Syndrome (SJS)
Stevens-Johnson syndrome requires immediate medical attention as it is a life-threatening condition. Patients with SJS are typically hospitalized, and treatment is focused on supportive care, preventing complications, and minimizing the risk of infection.
Medical professionals may discontinue potential causative medications and initiate systemic corticosteroids and intravenous immunoglobulins. These treatments aim to suppress the immune system, reduce inflammation, and prevent further damage to the skin and mucous membranes. In severe cases, patients may be transferred to burn units or intensive care facilities for specialized care.
Other Considerations
In both EM and SJS, supportive measures are crucial in the management of these conditions. This includes the administration of pain medications, maintaining fluid and electrolyte balance, and providing appropriate wound care. Patients may also require nutritional support to aid in healing and recovery.
Additionally, ongoing monitoring and follow-up care are essential to assess the progression of the rash and overall health of the individual. Dermatologists work closely with other healthcare professionals, such as ophthalmologists, to address potential ocular complications associated with these conditions.
