Juvenile Xanthogranuloma Presenting as Bilateral Non-Infiltrative Extraconal Superior Orbital Tumour in a 27 Year Old Nigerian Woman: Features, Management and Outcome

Abstract

Introduction Orbital masses in adults are often caused by systemic diseases or are associated with systemic manifestations. Juvenile xanthogranuloma as a cause is rare and unreported in Africa. We present clinical features, management, and outcomes of bilateral orbital adult onset juvenile xanthogranuloma. Case Presentation A 27 year old Nigerian woman presented with bilateral upper-lid lumps having lasted 5 months. These increased in size for about 1 month and stopped. Lid swelling was preceded by itchy eyes, redness of conjunctiva, and occasional mild pain. There were no visual or systemic symptoms. The lumps were firm, slightly mobile, not tender, and not attached to skin but rather to deeper structures. There was restriction on up-gaze but no proptosis or diplopia. Hematological, biochemical, and X-ray investigations were normal. Prednisolone tablets 10 mg daily for two weeks were not useful. Tissue biopsy was invaluable in diagnosis of this rare condition and disclosed juvenile xanthogranuloma. Partial surgical excision was done under lidocaine infiltration. No recurrence has occurred in 40 months of follow-up. No systemic disease has manifested. Conclusion Juvenile xanthogranuloma can present as bilateral superior orbital tumor in adults; functional and cosmetic aims were achieved by sub-total excision.
