Erythema multiforme presenting as chronic oral ulceration due to unrecognised herpes simplex virus infection.

摘要

A 54-year-old white woman was referred with a 3-month history of persistent, painful mouth ulcers occurring on the lip and tongue (Fig. 1), rendering talking and eating painful. There had been no improvement with topical steroid preparations, and the only treatment that cleared the ulcers was a 5-day course of oral prednisolone 30 mg/day. However, repeated courses were required as the ulcers recurred within a few days of each course.
