We report a case of primary lymphoma of the breast complicated by heart failure and alcoholic-decompensated hepatic cirrhosis. The patient was a woman in her 60s who noticed a right breast tumor growing 3 months previously. The size of the tumor was approximately 5 cm, and the tumor had infiltrated the skin. There was no metastasis to the axillary lymph node or other organs by CT. We performed right breast mastectomy. Pathology indicated diffuse large B cell lymphoma(DLBCL). We considered chemotherapy, but her general condition was not good because of hepatic cirrhosis, so we administered palliative care. Although chemotherapy is the first choice of treatment for DLBCL, it is necessary to individually consider each patient's circumstances.
