Osseous Hodgkin′s lymphoma with sternal involvement at presentation: Diagnostic challenges

Hodgkin′s lymphoma with sternal involvement at presentation is quite unusual. Owing to its rarity, it often poses vexing diagnostic challenges. We herein bring into focus a case of advanced stage Hodgkin′s lymphoma, presenting with a sternal mass, initially misdiagnosed and treated as Langerhans cell histiocytosis. On subsequent follow-up, the patient developed recurrence and repeat biopsy and imaging suggested Hodgkin′s lymphoma. The case report highlights the importance of clinical suspicion of unusual presentation of lymphohematopoietic tumors of the bone.
