RESUMEN
INTRODUCTION: Rosai-Dorfman disease (RDD) is a sinus histiocytosis with massive lymphadenopathy. This rare condition is a benign disease of unknown etiology. Bilateral orbital localization of RDD is rare. OBSERVATION: The authors report the case of a 6-year-old child who presented with bilateral orbital-palpebral masses associated with chronic cervical lymphadenopathy. There were no laboratory signs of inflammation. Serological and tuberculosis screening tests were negative. Histopathological examination of a lymph node biopsy established a diagnosis of Rosai-Dorfman disease. The patient underwent surgical excision of the orbital lesions followed by long-term corticosteroid therapy. A favorable course was observed, with no sign of recurrence after one year of follow-up. CONCLUSION: Rosai-Dorfman disease is very rare in its bilateral orbital presentation. Histopathological diagnosis remains challenging. In Africa, the presence of chronic oculo-palpebral tumor associated with or without cervical lymphadenopathy must raise the suspicion of Rosai-Dorfman disease after ruling out tuberculosis and lymphoma.

INTRODUCTION: Kikuchi-Fujimoto disease, or histiocytic necrotizing lymphadenitis, is a benign disease most commonly affecting adult females. It generally presents in the form of febrile cervical lymphadenopathy. This diagnosis must be considered in the setting of tropical medicine, dominated by a high prevalence of tuberculous lymphadenitis and haematological malignancies. CASE REPORT: The authors report the case of a 33-year-old Senegalese woman who presented with subacute cervical lymphadenopathy associated with fever and laboratory signs of inflammation. Serological and tuberculosis screening tests were negative. Histopathological examination of a lymph node biopsy, following failure of nonspecific antibiotic therapy, concluded on a diagnosis of Kikuchi-Fujimoto disease. A favourable course was observed in response to corticosteroid therapy. CONCLUSION: In Sub-Saharan Africa, the association of polyadenitis and febrile syndrome, after excluding tuberculosis and lymphomas, must raise the suspicion of rare diseases such as Kikuchi-Fujimoto disease.
