BACKGROUND: Rosai-Dorfman disease (RDD) is a benign lymphoproliferatif disorder characterized by cervical lymphadenopathies with a consistent risk of airways' compression and esthetical prejudice. Extra nodal localizations are also described. AIM: To report two pediatric cases of RDD. CASES: the first case concerned a patient with a prolonged nodal involvement of RDD. Remission seems to be natural although it coincided with a sulfaméthoxazole- triméthoprime therapy. The second case illustrated an extranodal form of RDD localized in soft tissue and paranasal sinus with extension to nasal cavity which were corticodependant. CONCLUSION: RDD is usually a benign disorder. Particular localizations, lack of effective therapy and the high risk of recurrence are important issues in this rare affection.
