the concomitance of lymphoma and breast carcinoma in the bone

The occurrence of both lymphoproliferative disorder and breast cancer is a rare event. While the condition of coexistence of lymphoma and breast carcinoma has been described in the lymph nodes [1] and in the spleen [2], no reports have been published concerning the same association in the bone. When there is a clinical suspicion that there may be a concurrence of diseases, radiological exams are carried out but the diagnosis requires histological confirmation with either biopsy or aspiration [3].
