It Takes a Village: A Comprehensive Approach to Myeloproliferative Neoplasms
Myeloproliferative neoplasms (MPNs) are a group of myeloid disorders that usually presents with elevated peripheral blood counts, hepatosplenomegaly and genetic alterations of tyrosine kinase genes. Due to a significant overlap in clinical, morphologic and laboratory findings, diagnostic workup of these patients is complicated and requires integration of numerous diagnostic modalities. Although certain genetic alterations are preferentially enriched in specific MPN types lacking the Philadelphia chromosome, none of them are disease defining; therefore, a thorough workup should always include a bone marrow biopsy for morphologic evaluation and diagnosis. This lecture will focus on specific bone marrow morphologic findings associated with MPNs, as well as on the importance of a comprehensive approach for accurate diagnosis and prognosis.
