Among the latter, megakaryocyte-derived TGF-β1 might be the most important in the pathogenesis of the stromal reaction in PMF (46–48). Peripheral blood expansion of both CD34-positive myeloid progenitors and endothelial cells provide additional evidence for aberrant bone microenvironment in PMF (49, 50). 1 summarizes the current speculation regarding the mechanisms of stromal reaction in PMF (51, 52). 5 Clinical Features and Diagnosis Most, but not all, patients with PMF are symptomatic at diagnosis.

Del(20)(q11;q13), del(13)(q12;q22), trisomy 8, trisomy 9, del(12)(p11;p13), monosomy or long arm deletions involving chromosome 7, and partial trisomy 1q] (66). the presence of either del(13)(q12;q22) or der(6)t(1;6)(q21–23;p21–23) is strongly suggestive of PMF diagnosis (67). 7 Clinical Course and Prognosis Primary MF displays a progressive course in the majority of cases, and disease complications include cachexia, peripheral edema, severe fatigue, excessive night sweats, low-grade fever, symptomatic portal hypertension, variceal bleeding, ascites, debilitating diffuse and/or extremity bone pain, and “idiopathic” pulmonary hypertension (68).
