Atypical presentation of a Langerhan’s cell histiocytosis of the forearm in a child.

Abstract

We report a case of a 2-year-old child presenting with right forearm pain. Based on imaging analysis, the initial diagnosis was osteomyelitis but the final diagnosis demonstrated by histology was Eosinophilic Granuloma (EG) of the forearm. We detail the rare radiological presentation of such a lesion, the various clinical presentations and the work-up advised in this context.
