Fuchs Syndrome with Isolated Oral Mucosa Lesions due to Severe Herpes Simplex Cheilitis in a Patient with Idiopathic Thrombocytopenic Purpura

Stevens-Johnson syndrome (SJS) is a severe dermatological disease classically characterized by erythematous target lesions and mucosal involvement. Fuchs syndrome is an incomplete presentation of SJS which has oral, conjunctival and genital manifestations but no skin lesions. To the best of our knowledge, our case of Fuchs syndrome in an 80-year-old man is the first such case related to herpes simplex virus (HSV)-1 infection to be described. Our patient quickly recovered following IVIG therapy, although specific treatment is still a topic of discussion. Research is required on this poorly understood dermatological disease to determine optimum therapy. LEARNING POINTS: We report a case of Fuchs syndrome in an elderly man after HSV-1 cheilitis. Therapy always includes discontinuation of the causative drug. Specific therapy for Stevens-Johnson syndrome and Fuchs syndrome is still a topic of discussion, although we noted marked improvement following the administration of IVIG therapy.
