Erythema Multiforme-Oral Variant: Case Report and Review of Literature

“…Most patients have chronic or recurrent oral lesions only, but one-third have oral and lip lesions and one quarter have oral, lip, and skin lesions. This variant is a reaction pattern similar to EMm and EMM [3].…”

“…In EMm, there is usually a mild extension of erythematous patches or superficial erosions of the oral mucosa and the lip. Target lesions may be seen on the lip but rarely on the intraoral mucosa [3].

“…Affected patients may have trismus, dysphonia, dysarthria, and/or dysphagia. The oral lesions of EMM usually heal without scarring, and in some instances there can be hyperkeratotic plaques mixed with erythematous areas [3]. Other mucosal surfaces including ocular, nasal, pharyngeal, laryngeal, lower respiratory, and anogenital may be involved.…”
