Agnogenic myeloid metaplasia is a hematologic disorder accompanied by extramedullary hematopoiesis (EMH) affecting various organs. Lung involvement however is rare. We present the case of a 76-year-old woman with myelo®brosis, recurrent pleural effusions, pulmonary hypertension, and serious right cardiac failure. An open lung biopsy con®rmed pulmonary EMH. She underwent low-dose (200 cGy) whole-lung radiotherapy in 4 fractions of 50 cGy each. Her clinical and hemodynamic parameters improved. We conclude that low-dose whole-lung radiation may be ef®cacious for the palliative treatment of pulmonary EMH. Am.

We conclude that the finding of epithelial cells in BM of BC patients correlates with several known prognostic factors and has adverse impact in the DFS and OS of these patients that seems, however, to decrease with time.

Thalidomide and its analogs have been extensively studied in patients with multiple myeloma. We present the case of a 58-year-old female patient with immunoglobulin GA-kappa multiple myeloma who was receiving thalidomide after failing an autologous transplant. She presented with profound asthenia and several space-occupying hepatic lesions, one of which was shown by a CT-guided percutaneous biopsy to be plasmacytoma. The patient then received bortezomib and had a transient response. Because thalidomide may also increase the expression of cytoadhesion molecules in myeloma cells and in the bone marrow microenvironment, it is possible that some patients with multiple myeloma who relapse on thalidomide may present with extramedullary plasmacytomas, as seen in this case. Therefore, whenever symptoms arise in patients with multiple myeloma who are receiving thalidomide, extramedullary plasmacytomas should be considered.
