In 31 patients with chronic myeloid leukemia, the initial bone marrow biopsy constantly showed considerable cell richness. The maturation of the granulocytes was harmonious in 52% of cases, with a predominance of myelocytes in 32% of cases, and groups of myeloblasts in 13% of cases. Eosinophilia was frequent and fairly intense. Fairly numerous loaded cells and Charcot-Leyden crystals were signs of granulocyte failure in the bone marrow. The erythroblasts were reduced, the megakaryocytes increased. Myelofibrosis was present in 45% of cases. This gave a very characteristic histological appearance. It was not possible to draw up correlations between the type of granulocyte maturation and/or the presence of myelofibrosis and, on the other hand, the clinical course of the disease, but the small number of case studied both in our series and in the literature do not permit one to carry out a proper statistical study.

A new technique which detects the presence of DNA polymerase and primer-template DNA by measuring the incorporation of 3H-thymidine-5-triphosphate (3H-TTP) showed cytoplasmic labelling of eosinophilic granulocytes and eosinophilic myelocytes in normals, in acute leukaemia, in chronic myeloid leukaemia and in patients with eosinophilia of unknown origin.

A 47-year-old white male developed massive hepatosplenomegaly, a pleural effusion, leucocytosis, and a left parasternal mass following a relatively symptom-free persistent hypereosinophilia for about 5 years. Bone marrow aspiration and biopsy and peripheral blood differential showed eosinophilia and a shift to the left with immature cells. A high serum B12 vitamin level and low LAP activity were found. Biopsy of the soft tissue mass revealed a granulocytic sarcoma (chloroma) with a hyperdiploid karyotype (49,XY, + 10, + 15, + 19,3q-), whereas the bone marrow cells had a normal male karyotype. The patient responded temporarily to chemotherapy but eventually developed CNS leukemia and went on to terminate in a frank blastic phase. This case illustrates hypereosinophilia and a myeloproliferative syndrome characterized by a somewhat indolent chronic course evolving into "eosinophilic leukemia" and granulocytic sarcoma, CNS involvement by leukemic cells and, finally, blastic transformation. It is possible that this case represents a variant of Ph1-negative CML to which the term "chronic eosinophilic leukemia" could be justifiably applied.

Epidural myeloblastoma, which compressed the spinal cord, was the first evidence for chronic granulocytic leukemia, eosinophilic type, Ph chromosome negative. This manifestation was preceded by 3 years follow-up of a patient with persistent eosinophilia of 60% mature eosinophils. The only clues for the diagnosis of leukemia were splenomegaly and high serum vitamin B12, most of which was bound to transcobalamin I. The latter finding presents a useful diagnostic criterium in myeloproliferative disorders.

We report a patient with Ph+ chronic myelogenous leukemia (CML) whose recurrent blast crises were associated with marrow eosinophilia and inv(16). After intensive chemotherapy, for each blast crisis, the patient reentered chronic phase with disappearance of both the inv(16) and the eosinophilia.

Lymph nodes from 21 cases of generalized mastocytosis were studied histologically to confirm or exclude mast cell infiltration, and to investigate their micro-architecture. Mast cell infiltrates were detected in 17 (80%) of the lymph nodes and were found mainly in the medullary cords and sinuses. Diffuse infiltration was seen in 14 cases and focal infiltration in three cases. The following pathological findings were frequently observed: germinal centre hyperplasia (n = 14), which is probably a nonspecific finding; and hyperplasia of small blood vessels, which sometimes resembled high endothelial venules (14), eosinophilia (8), plasmacytosis (7) and collagen fibrosis (6), all of which may well be related to the effects of mediators released by mast cells. Infiltrates of acute or chronic myeloid leukaemia were seen in six lymph nodes. Division of the cases into two prognostically different groups, i.e. systemic mastocytosis, in which the skin lesions of urticaria pigmentosa are present and the prognosis is favourable, and malignant mastocytosis, in which there is no cutaneous involvement and the prognosis is poor, revealed that all six lymph nodes exhibiting leukaemic infiltrates came from the malignant mastocytosis group; eosinophilia, plasmacytosis and fibrosis were seen significantly more often in malignant than in systemic mastocytosis, but blood vessel hyperplasia and germinal centre hyperplasia were encountered with the same high frequency in both groups; and mast cell atypia tended to be more pronounced in malignant mastocytosis; this diagnosis could therefore easily be missed without naphthol AS-D chloroacetate esterase staining.(ABSTRACT TRUNCATED AT 250 WORDS)

Myelodysplastic syndrome (refractory anemia with excess of blasts; RAEB) with marked basophilia and eosinophilia is described. An 82-year-old male was admitted to our hospital because of severe normocytic normochromic anemia (Hb 5.6 g/dl). The white cell count was 9,200/microliters with marked basophilia (34.5%) and eosinophilia (19.5%). The bone marrow aspiration also revealed both basophilia and eosinophilia, with blast contents of 9%. Diagnosis of RAEB was established. Although the treatment with red cell transfusion and ubenimex (Bastatin) was started, anemia was not improved. A karyotype of the bone marrow cells from this patient showed 47, XY, +8, i (17q), which has been observed as additional chromosomal abnormalities in blastic crisis of chronic myelogenous leukemia. The diagnosis of CML was not compatible with this case, because Ph1 chromosome and bcr gene rearrangement were negative. It is concluded that eosinophilia and basophilia might be derived from clonal abnormalities associated with MDS.

We report a case of chronic myeloid leukemia (CML) in myelomonocytic transformation associated with bone marrow (BM) eosinophilia. At diagnosis, all BM cells showed a Ph chromosome. At the time of blastic phase, more than 50% of Ph+ cells had a pericentric inversion of chromosome 16, inv(16)(p13q22). This case confirms that blastic transformation of CML can involve any committed progenitor, and myelomonocytic leukemia with BM eosinophilia is specifically associated with rearrangement of chromosome 16 at band p13 and q22.

Two cases are described with the rare combination of inv(16)(p13q22), strongly associated with acute myelomonocytic leukemia with eosinophilia, M4Eo, and the Philadelphia translocation, t(9;22)(q34;q11), hallmark of chronic myeloid leukemia (CML) and rarely found, (less than 1%), in acute nonlymphocytic leukemia. The patients were: case 1, a 9-year-old girl presenting with a white blood cell count (WBC) 42 x 10(9)/L with 32% blasts and bone marrow with blasts and eosinophil precursors consistent with M4Eo, and case 2, a 25-year-old man with WBC 34.7 x 10(9)/L with 13% blasts and bone marrow with features of M4Eo and basophilia. Both patients achieved remission but died following bone marrow transplantation in first remission (case 1) or in relapse (case 2). Cytogenetic findings were: case 1, at diagnosis, 46,XX,inv(16)(p13q22)(21)/46,XX,t(9;22) (q34;q11),inv(16)(8)/46,XX(10), and case 2, at diagnosis, 46,XY,t(9;22) (q34;q11),inv(16)(p13q22) (16) and in remission, 46,XY,t(9;22)(q34;q11) (1)/46,XY (24). Investigation of the breakpoint on 22 in case 1 with Southern blotting and the polymerase chain reaction demonstrated the presence of a p190 mRNA and a breakpoint typical of acute leukemia. Thus a diagnosis of M4Eo was supported by clinical and cytogenetic sequelae in each case; the Ph in case 1 was apparently secondary to inv(16), in case 2 the Ph probably preceded inv(16) in the etiology of the leukemia.

33 cases of chronic granulocytic leukemia (CGL) were reassessed to determine if, by strict morphologic criteria. Philadelphia chromosome (Ph1)-negative CGL exists as a diagnostic entity and if Ph1-positive CGL could be distinguished from Ph1-negative CGL. Cases were reassessed using published criteria and, of 11 Ph1-negative cases, only 4 could be reclassified as myelodysplastic syndromes or undifferentiated chronic myeloproliferative disorder. Of the morphologic parameters evaluated, peripheral blood basophilia and bicytopenia proved to be good discriminators between Ph1-positive and Ph1-negative cases. As a group, Ph1-negative cases were more heterogeneous and tended to have lower hemoglobin, WBC, platelet count and absolute eosinophilia. Chromosomal abnormalities other than Ph1 were seen only in the Ph1-positive cases. Based on these findings, we conclude that Ph1-negative CGL constitutes a heterogeneous group, a subgroup of which is morphologically identical with the Ph1-positive CGL. The parameters that best discriminate between Ph1-positive and Ph1-negative cases are peripheral blood absolute basophilia and bicytopenia.
