Conclusion
Our case emphasizes the importance of considering RS as a differential diagnosis in all patients with LE presenting EM-like lesions in the absence of triggering factors. Not being able to do so results in underdiagnosis and underestimation of the disease, which will result into irreversible complications. Certainly, clinicians need to be aware of the cutaneous signs associated with systemic diseases to facilitate early diagnosis and timely treatment before potentially life-threatening complications develop. Hence, thorough and comprehensive research needs to be undertaken to establish the existence of RS as a separate entity.
