LC can be defined as myeloid sarcoma or granulocytic sarcoma, in which the infiltrate is characterized by neoplastic granulocytic precursors; otherwise, when the infiltrate is composed of neoplastic monocytic precursors (monoblasts and promonocytes), LC can be labeled monoblastic sarcoma (1).
It was shown that cFXIII-A is present from a very early stage of monocyte differentiation (monoblasts in the bone marrow) [27,28] to the macrophages of connective tissue and serous cavities [29].
