The case of an infant with the clinical and haematological features of chronic myelomonocytic leukaemia is reported. The infant presented with a peripheral blood monocyte count of 12,000 cell/mm3 (12.0 X 10(9) cell/L) but no lymphadenopathy, hepatomegaly, nor splenomegaly. No treatment was given for 14 months during which time the monocytosis persisted. Myeloblasts then appeared abruptly in the peripheral blood reaching a peak of 1,500,000 cell/mm3 (1,500 X 10(9)/L). Cytotoxic chemotherapy was initially successful but the blast soon became resistant and the child died. Chronic myelomonocytic leukaemia is usually associated with the elderly and the significance of this case is discussed.

The clinical and hematologic characteristics of 38 children with subacute and chronic myelomonocytic leukemia (S & CMMOL) are described, and the prognostic significance of these characteristics as recorded at diagnosis is reported. The common and distinctive feature of these children was the excessive proliferation of cells of neutrophilic and monocytic series. The disease predominated in younger children, 95% were younger than 4 years, and boys were more affected than girls (22/16). The onset of the disease was heralded most often by acute or subacute symptoms. Splenomegaly was the most common physical finding at diagnosis. Leukocytosis was usually under 100 X 10(9)/l. Monocytosis and granulocytosis were often associated with normoblastosis, and, in some cases, with moderate blastosis (less than or equal to 30%). Severe anemia and marked thrombocytopenia were found in about one third of patients, increased fetal hemoglobin levels in 53%, and increased gamma-globulin levels in 50% of cases. The Philadelphia chromosome was absent in all blood and marrow cell karyotypes. Thirty-three of 38 patients were treated with moderate or intensive chemotherapy, and in all cases treatment never resulted in a complete remission. Terminal acute leukemia occurred in 11 cases. Of the 38 patients, 29 have died (median survival time, 16 months). Initial characteristics predicting a short survival (log-rank test) included: older age (greater than or equal to 2 years) (P less than 0.001), hepatomegaly (P less than 0.05), bleeding (P less than 0.001), thrombocytopenia (P less than 0.01), high counts of blasts and normoblasts in peripheral blood (P less than 0.01, P less than 0.01). Sex, infections, cutaneous manifestations, lymphadenopathy, degree of splenomegaly, hemoglobin levels, fetal hemoglobin, leukocyte counts, percent of blasts in bone marrow, and serum gamma-globulin levels were of no prognostic value. When survival was plotted on a semilogarithmic scale, a change in death rate was evident at the second year of survival suggesting that there may be two subgroups of patients with myelomonocytic picture, one with very rapid, and another with a slower rate of mortality. A stepwise discriminant-function analysis was performed in an attempt to distinguish between those children who lived less than or equal to 2 years and those who lived longer. A linear combination of variables which best discriminated between these two subgroups was found. Nearly all patients could be classified as a short-survivor or long-survivor on the basis of age and platelet, blast, and normoblast counts in peripheral blood.(ABSTRACT TRUNCATED AT 400 WORDS)

A 41-year-old patient with dermatitis herpetiformis (DH) developed steroid-resistant blebs as a sign of exacerbating DH. The skin symptoms were resolved after 2 weeks of oral administration of diaminodiphenyl sulphone (DDS). However, 3 weeks after the start of DDS, he suffered from edematous eruption on the cheeks and neck, enlargement of the pharynx, systemic lymphoadenopathy and hepatomegaly. In addition, his leukocyte count increased rapidly from 10.1 x 10(9)/l with 13% monocytes just before the start of DDS, to 24.6 x 10(9)/l with 28% monocytes. Bone marrow aspirate showed trilineage dysplasia and chronic myelomonocytic leukemia (CMML) was diagnosed. The patient died from septic shock during neutropenia following cytotoxic chemotherapy. In this case, CMML was complicated with DH and the administration of DDS accelerated the progression of CMML with the manifestations of DDS syndrome. Although DDS is a well-established drug for DH, DDS should be used with great caution when a hematological malignancy coexists.

Several authors have tried to solve the problems in the classification of CMML. A fully suitable classification does not exist. The goal of our study was to determine common and different signs of MD and MP type of CMML and to observe frequency of shifts from MD to MP-CMML. Sixty nine CMML patients were divided according to FAB proposal into two groups: 31 patients into the MD group (WBC < or = 13 x 10(9)/l) and 38 patients into the MP group (WBC < or = 13 x 10(9)/l). Presenting features and the course of the disease in both groups were evaluated. The median age of patients was not different in both groups (71.5 and 74 years, respectively), male/female ratio was 1.1 and 2.4, respectively. The median follow-up time was 15.5 months (1-58.8) in MP group and 24 months (2-118) in MD group. In MP group splenomegaly, hepatomegaly, lymphadenopathy, abnormal karyotype and skin involvement were found more often than in MD group. Median LDH value was higher in MP group. Probability of survival was higher in the MD group than in MP group (median 30 and 11 months, respectively). Leukaemia transformation frequency was similar in both groups. In 12 out of 24 (50%) MD group patients WBC increased during the course of the disease over 13 x 10(9)/l. Oscillation of WBC values below and over 13 x 10(9)/l was observed in three patients. During the follow-up time number of patients with splenomegaly and/or immature granulocytes in the PB increased. After inclusion of 12 patients who shifted from MD to MP group a new CMML group resulted characterised by longer median survival (17 months) due to a higher number of patients in an earlier stage of the disease. Failure of evolution of myeloproliferative signs and lower frequency of AL in the remaining group might be explained by an early stage of CMML, untimely deaths due to unrelated causes and/or by patients suffering of RA with monocytosis rather than of CMML. In summary, our data suggest, that evolution from MD-CMML to MP-CMML is a frequent event and that MD-CMML could be the early stage of CMML in most of cases. The WBC at diagnosis as the single criterion for subclassification of CMML does not seem to be fully justified. We propose that CMML should not be divided in MD and MP types and that monitoring of patients and search for other signs of myeloproliferation such as PB immature granulocytes, splenomegaly, lymphadenopathy, skin involvement, pleural or peritoneal effusions, spontaneous growth of CFU-GM in vitro should be taken in consideration for a better classification of CMML, which would have an impact on the therapeutic approach.

A 68-year-old man with chronic myelomonocytic leukemia (CMML) was initially treated with hydroxyurea with subsequent stable disease. In the time course, he developed bilateral pleuritis accompanied by leukocytosis and spiking fever. Cytologic analysis of the pleural effusion revealed abundant mature granulocytes and monocytes. He was treated with intravenous or oral etoposide with consequent resolution of the pleuritis, indicating the pleural involvement of CMML. Three months later, he developed hepatomegaly and became febrile. One month thereafter, the CMML transformed to acute myeloid leukemia, and the patient developed massive bloody stools associated with epigastric pain and leukocytosis. A gastrofiberscopic examination showed multiple bleeding gastric ulcers. The bleeding ulcers were treated with the clipping procedure; however, the bloody stools continued. Although intravenous etoposide was effective for the leukocytosis and hepatomegaly, the treatment did not improve the bloody stools. The patient finally died of panperitonitis. The autopsy showed multiple ulcers of the transverse colon, some of which were perforated. Microscopically, the ulcerated areas were densely infiltrated with leukemic cells predominantly consisting of immature monocytes and granulocytes. This patient may be the first reported case of CMML complicated by colonic perforation due to leukemic infiltration.
