  Abstract 

Development of clinically apparent bone marrow involvement is a rare occurrence in metastatic breast cancer. We are reporting a case of 60-year-old female patient with breast carcinoma and simultaneous total bone marrow replacement by the carcinoma cells, mimicking an acute leukemia at presentation, which has not been reported in the literature.

  Introduction Top


Symptomatic involvement of bone marrow is an extremely rare occurrence in metastatic breast cancer as compared to micrometastasis in bone marrow. [1] Bone marrow carcinomatosis is clinically suspected in patients with advanced stage disease and unexplained cytopenias. [2] Presence of total marrow replacement by carcinoma cells in the initial presentation itself is an extremely rare event which is not yet described. We are presenting this case because of this rarity.


  Case report Top


A 60-year-old female patient presented with a lump in the breast of 6 months duration. Local examination revealed left-sided breast lump measuring 4 cm × 2.5 cm in the upper and lower inner quadrant of the breast with no nipple, skin or chest involvement. Multiple left axillary lymphnodes were also present with the largest lymphnode measuring 2 cm × 2 cm. Right breast and axilla were normal. Routine laboratory investigations revealed hemoglobin - 5.8 g%, TC - 6900/mm 3 , platelet count - 60,000/mm 3 . Peripheral smear examination revealed a leukoerythroblastic blood picture. Bone marrow aspiration revealed total replacement of the bone marrow by atypical cells with scanty basophilic cytoplasm and round to oval nucleus with an immature chromatin [Figure 1]a and b. Atypical cells were myeloperoxidase negative by cytochemistry. Bone marrow biopsy also confirmed the total replacement of the marrow by the same atypical cells [Figure 1]c. Immunohistochemistry was done on bone marrow biopsy. Tumor cells were positive for pancytokeratin, cytokeratin 7, negative for E-cadherin and positive for estrogen receptor [Figure 1]d-f. Trucut biopsy done from the breast lump also showed the same tumor cells arranged singly and in Indian file pattern [Figure 1]g. Thus, diagnosis of invasive lobular carcinoma of the breast with extensive bone marrow infiltration was given.

  Discussion Top


There is a paucity of published data on the incidence of clinically apparent bone marrow carcinomatosis in breast cancer. One of the largest case series studying bone marrow involvement in breast cancer revealed only 0.17% of patients with this condition. [1] In routine clinical practice, presence of leukoerythroblastic blood picture is regarded as a sign of bone marrow involvement after ruling out hematologic causes like hemolysis, myelodysplastic syndrome or a myeloproliferative neoplasm. [3],[4] Studies have shown a close association between bone metastasis and bone marrow involvement. Bone marrow may be the initial site of metastatic disease in bones, and osseous metastasis would result by invasion from marrow. [5] Although bone metastasis can occur in metastatic disease, most of them will be presenting as osteolytic metastasis in bone rather than as diffuse bone marrow infiltration. There are case reports of synchronous occurrence of carcinoma of the breast and acute myeloid leukemia. [6] Breast cancer can also present synchronously with malignant lymphomas. [7],[8] Clustering of blasts is described in acute myeloid leukemia which can also present in breast as granulocytic sarcomas. [9],[10]


  Conclusion Top


Immunohistochemistry is absolutely indicated to distinguish metastasis from breast cancer and a hematologic malignancy in such difficult scenarios. Our search of literature did not reveal any reported case of metastatic breast cancer with total marrow replacement by the tumor cells in its very initial presentation, thus simulating an acute leukemia, which prompted us to report this interesting case.
