Concurrent presentation of nodal myeloid sarcoma and bone marrow chronic lymphocytic leukemia/small lymphocytic lymphoma: a unique association.

Myeloid sarcoma (MS), previously known as granulocytic sarcoma, is a rare, localized, tumor mass composed of myeloid precursor cells, with or without maturation, and occurring at an anatomical site other than the bone marrow (BM). Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), in contrast, is a B-cell hematological malignancy. We describe the first reported case of concurrent presentation of nodal MS and of BM CLL/SLL in the same patient.

Synchronous BALT Lymphoma and Squamous Cell Carcinoma of the Lung: Coincidence or Linkage?
