Lingual traumatic ulceration (Riga-Fede disease).

An 11-month-old male infant was referred to our clinic because of a painful ulcer of approximately 5 months' duration on the ventral surface of the tongue (Fig. 1). On physical examination, the lesion was circular (3 cm x 2 cm) with erythematous, raised, and indurated borders. No pathologic findings emerged from the laboratory data, neurologic examination, or clinical history. The family history was also negative for developmental disorders and congenital syndromes. No biopsy was performed in view of the age of the infant, the particular site of the lesion, and the clinical evidence of diagnosis. The treatment included odontologic cream (methylvinylether/maleic acid) as a protective shield, a collutorium (chlorhexidine 0.2%), and the use of a teething ring. Complete healing of the lesion (Fig. 2) occurred within 3 weeks.
