The mRNA expression level of the gene delta-like (Dlk), coding for a signal transducer related to the Delta-Notch family, was measured using real-time PCR methodology in a large series of control biopsies (n = 61) and bone marrow trephines from patients with myelodysplastic syndrome (MDS) (n = 93) and related myeloid disorders (AML, n = 16 and chronic myeloproliferative disease (CMPD), n = 38). It turned out that dlk is strongly overexpressed in a subset of MDS (16%) cases, however with higher frequency in blast rich MDS cases. Therefore, the quantitative detection of dlk mRNA can support the morphological diagnosis of MDS in selected cases.

In the study of patients with Hodgkin's lymphoma (HL) the evaluation of bone marrow biopsy (BMB) can be difficult. In this review we analyze the main diagnostic features and the clinical risk factors of BM involvement. Although the role of BMB is criticized by some authors, its value is irreplaceable in the staging of HL and in the diagnosis of primary medullary HL. The Ann Arbor staging committee criteria should be revised and updated in the light of the current immunohistochemical studies that give a fundamental help in the diagnostic process. A single BMB should be adequate for diagnosis in most instances. In cases of suspicious involvement a controlateral BMB could be performed.
