Herpes Simplex Virus (HSV)-Induced Erythema Multiforme: A Rare Case Report.

A polymorphous recurrent eruption mostly composed of macules, bullae, papules, and target lesions, which are often distributed symmetrically and can spread to distant extremities, and oral mucosae are the features associated with erythema multiforme (EM). Herpes simplex virus (HSV) is a common condition that is associated with EM and manifests in late adulthood. It shows recurrence and is usually diagnosed clinically. Following is a case of HSV-associated EM. A 45-year-old patient visited the outpatient department with complaints of oral ulceration and associated pain and burning sensation. The patient also reported that similar ulcers were seen two months prior to her visit, which resolved on their own and the recurrence was seen two days prior to the visit. The recurrence occurred with more severity of pain and inflammation as compared to previous ulcers. The patient was kept on a combination therapy of antivirals, steroids, silymarin, and multivitamins for four visits with a tapering dose of steroids. Post-treatment, there was no recurrence till date and the patient is able to perform mastication as well as deglutition without any pain or burning sensation.
