The great mimicker – Case report of eosinophilic granuloma of proximal radius and review of literature

Eosinophilic granuloma is an uncommon bone tumour consisting of circumscribed lesions of the reticuloendothelial system usually confined to the bone. We present a case report of 28-year-old male who complaints of swelling over proximal end of radius associated with pain for a duration of 1 year. The patient was successfully treated with open biopsy followed curettage and intralesional methyl prednisolone injection using Boyd’s approach. Histopathology reported the lesion as eosinophilic granuloma. Patient was followed up in our outpatient department and found to be symptom free with evidence of resolution of tumour. This case study adds to the current understanding and treatment of eosinophilic granuloma. Eosinophilic granuloma is always a diagnostic challenge for the surgeon. Clinical findings and investigations are usually non-specific. Histopathology and immunohistochemistry still remains the mainstay in diagnosis of EG. Always suspect it, lest you will miss it.
