ABSTRACT
Allergic contact stomatitis is a well-recognized entity, which may be easily overlooked by the clinician since its signs and symptoms are similar to various other oral lesions. Accurate diagnosis warrants adequate treatment that will help in providing prompt relief and will also prevent further recurrences. We present a case report of a 27-year-old South Indian male student, who presented with multiple erythematous erosions involving much of the nonkeratinized oral mucosa. History revealed that there was a previous episode of a similar lesion, associated with intake of food with flavoring agents. Based on the history and clinical features, we arrived at a diagnosis of allergic contact stomatitis and successfully treated the lesions with topical and systemic antihistamines.
