We report female monozygous twins who developed acute lymphoblastic leukemia at the age of 5 1/2 years. The diagnosis in the first twin was made after pallor, lethargy, and petechiae developed. The diagnosis in the second twin was made two days later when a whole blood count was taken. The lymphoblasts of both patients showed with the exception of the PAS-reaction identical morphological, cytochemical, and immunological results. The PAS-reaction was positive in 55% of the lymphoblasts in one twin, negativ in the lymphoblasts of the other twin. Both patients are in continuous complete remission 14 months after diagnosis. The risk of leukemia is high in the other monozygous twin when one of the twins has already developed leukemia. In the literature it is estimated to be 1 : 5. The diagnosis after the second year of life is rarely made at the same time. There is only one previous report of this occuring in a case of acute myeloblastic leukemia in 4 1/2 year old monozygous twins.

Fifty children with oral manifestations of acute leukemia, ranging in age from 1 to 14 years, have been studied with reference to age, sex, location and clinical presentation of the oral lesions. Seventy six percent of the patients had the disease during the first decade of their life, 22% as acute myelocytic leukemia and 54% as acute lymphocytic leukemia. In the current study, acute leukemia exhibited a high predilection for males (70%) and mucosal pallor was the most common presenting oral symptoms (39.6%). Erythema, ulceration and swelling of the lip, tongue, palate and gingiva were also frequent symptoms. Extra oral involvement occurred in 60% of the cases as facial pallor and 11% as lymph node enlargement.

Forty-three adult cases of acute leukaemia (AL) seen at the University of Benin Teaching Hospital, Benin City, Nigeria in the 13-year period 1975-1987 have been analysed with respect to the presenting features, management and outcome. The percentage incidence of AML and ALL were 51.2 and 23.3 respectively. There is a preponderance of male patient (male:female ratio was 2.1:1, 2.3:1, 1.3:1, and 3:1 respectively for AML, ALL, BC and ALSCL). Most cases of AL occurred in the 21-30-year age bracket. Pallor (77.3%) is the commonest presenting feature in AML whereas night sweats and lymphadenopathy occurred in most cases of ALL (80%). The main causes of death are haemorrhage and infection. Treatment is generally inadequate and so the results of treatment are poor.

Nineteen cases of canine acute leukemia were diagnosed during a 4-year period. Two main categories were identified on the basis of cytologic, hematologic, and clinical features: acute lymphoid leukemia and acute myelogenous leukemia. Clinical features included history of weight loss, anorexia, shifting limb lameness, and incoordination. Physical findings were characterized by hepatomegaly, splenomegaly, mild generalized lymphadenopathy, and pallor. Ocular lesions were found in 29% of dogs with acute myelogenous leukemia. Hematologic abnormalities included anemia, thrombocytopenia, pancytopenia, leukemia, and leukoerythroblastic reactions. Results of therapy were discouraging.

A case representing previously misdiagnosed acute myeloblastic leukemia associated with an absence of classical intraoral manifestations is presented. Platelet count was less than 15,000, and hematocrit was 20.3, yet clinical signs were limited to malaise and extreme gingival and mucosal pallor. The typical initial signs of gingival enlargement or hemorrhage never appeared, probably due to excellent plaque control by this patient. Mucosal color changes dictated the need for laboratory studies leading to a rapid and relatively early diagnosis.

Between 1976 and 1979 a myeloproliferative disease associated with cells monosomic for chromosome number 7 in the bone marrow was seen in six boys aged 5 1/2 months to 8 years (median 10 months). Presenting features included hepatosplenomegaly (5/6), respiratory infections (4/6), pallor (2/6) and skin infections (1/6). Haematological features included a leucoerythroblastic anaemia with leucocytosis and thrombocytopenia, and a hyperplastic marrow with a slight excess of blasts. Fetal haemoglobin was normal in four patients and mildly raised in the other two. Neutrophil function tests showed defective chemotaxis with reduced killing, despite a normal NBT test. Cytogenetic analysis of the marrow showed a preponderance of cells with monosomy 7; the blood lymphocytes were cytogenetically normal. In three patients the disease progressed to acute myeloid leukaemia (AML) after 3 weeks to 23 months; the only patient who remitted did so in response to 6-mercaptopurine and prednisolone, but relapsed 16 months later. A fourth child developed massive splenomegaly which initially responded to 6-mercaptopurine and prednisolone, but progressed to myelofibrosis 11 months later. A fifth child died from anaemia and respiratory infection without progression to leukaemia and the sixth patient has not yet developed leukaemia. Monosomy 7 is the diagnostic criterion of one of the more common myeloproliferative states in childhood and carries a high risk of progression to AML. The acute phase is usually resistant to chemotherapy, but even in responsive cases treatment does not result in elimination of the abnormal clone. Allogeneic bone marrow transplantation should be considered in cases with a suitable donor.

CGL is a highly specific disease that is defined by strict hematologic parameters that include a pathognomonic differential leukocyte count. Usually CGL is accompanied by the presence, in bone marrow cells, of the Ph chromosome, the first chromosomal anomaly to be regularly associated with a human neoplastic disease. CGL is predominantly a disease of the productive middle years of life, which maximizes its adverse impact on family life and family economics. The disease is of worldwide distribution and there is a slight male preponderance. The disease is characterized by an initial chronic phase when it behaves as a differentiated neoplasm and responds very well to simple, nonintensive therapy. After a variable interval, CGL undergoes metamorphosis to a refractory phase that responds poorly or sometimes not at all to therapy, even when this is intensive. At the stage of metamorphosis a great variety of clinical and hematologic pictures occur, and CGL may mimic a myeloproliferative disease, a myelodysplasia, a subacute leukemia, AML, or ALL. The old concept of an abrupt, explosive transition from the chronic phase to a so-called blastic crisis is incorrect: this rarely occurs and in most patients who are carefully followed, CGL is observed to undergo two or more stepwise evolutions, eg, from chronic phase to an accelerated myeloproliferative phase to a phase that resembles AML. Many patients with CGL conform to an established pattern of clinical features. There is a history of insidious symptoms of anemia and of splenomegaly. The physical signs are those of pallor and marked splenomegaly, while the hematologic findings are of moderate anemia, moderate thrombocytosis, and a marked granulocytic leukocytosis with a specific differential count. The radiologic findings are typically normal. Diagnostic difficulty seldom arises with this classic presentation. The patient who is detected at an early stage of CGL may lack the history, physical signs, and fully developed hematologic picture of CGL. Before the availability of cytogenetic studies, the diagnosis could only be established with confidence by observing the patient until the typical features of the disease emerged. Also considered are the less frequent but important atypical presentations of CGL. The symptoms and complaints, findings on examination, complications and hematologic findings may depart from the typical case in a bewildering variety of ways, so that the diagnosis may be difficult, indeed, CGL is generally not the initial diagnosis that is made. When the patient with CGL has received treatment, it is usual for he or she to become asymptomatic, with no abnormal physical signs.(ABSTRACT TRUNCATED AT 400 WORDS)

The French-American and British (FAB) classification of 62 consecutive cases of acute myeloid leukemia was undertaken. AML-M2 was the commonest FAB type (32.26%), followed by M1 and M4 (22.58% each), M5 (8.6%) and M6 and M7 (1.61% each), respectively. One of the patients was diagnosed as AML-MO (not a FAB type). The mean age of M1, M2, M3 and M5 cases was between 25 and 29 years, whereas in M4 patients it was 45.6 years. AML-M2, M4 and M5 were commoner in males, M1 in females and M3 equal in both sexes. Feeling of weakness, easy fatiguability and pallor were invariably present in all FAB types. All the patients of M1 and M5, 85% of M2, 64% of M4 and 50% of M3 presented with fever. Bleeding manifestations were most frequent in M3 cases followed by M5, M1, M4 and M2, respectively. Hepatomegaly and splenomegaly were relatively less prominent features in M3 as compared to other FAB types. Amongst the haematological parameters, anaemia was more severe in M1, leucocytosis in M2 and thrombocytopenia in M3 cases as compared to other FAB types.

In 31 patients of myelodysplastic syndrome, RAEB-t was the commonest subtype (29%), and RARS, the lease common (6.4%); 19.4% were characterised as the unclassifiable (UC) group. Pallor was the dominant sign (90.3%). Low haemoglobin in RA & RARS (p<0.05), thrombocytopenia in RAEB-t (p<0.01) and high leuco/monocyte counts in CMML (p<0.001) were observed. Neutropenia occurred most frequently in RAEB & RAEB-t and circulating blasts in all cases of RAEB-t and CMML. Bicytopenia was the commonest finding (58.1%) and pancytopenia the least (16.1%). 84% of marrows were hypercellular and trilineage dysplasia was seen in 68% of patients. Megaloblastoid dyserythropoiesis was the predominant feature in all cases, dysgranulopoiesis in all cases of RAEB, RAEB-t and CMML, and micromegokaryocytes in all cases of RARS, RAEB & CMML were seen. RAEB-t and RAEB (33.3% each) were the predominant groups which progressed to leukemia, FAB AML-M2, being the commonest type (60%).

There were eleven cases of pure red cell aplasia diagnosed over a period of 2 years (January 2000-December 2001). All the patients had anemia with pallor and weakness being the presenting complaints. Hematological profile depicted normocytic normochromic anemia, reticulocytopenia and marked paucity of erythroid precursors on bone marrow aspiration and biopsy studies. In the present study, one case was of congenital pure red cell aplasia, in one other case of pyrexia of unknown origin, no definitive diagnosis could be made. Other associated diseases seen with pure red cell aplasia were thymoma, septicemia, protein energy malnutrition, non-Hodgkin's lymphoma, juvenile rheumatoid arthritis, acute myeloid leukemia, tuberculosis and hepatitis C. The association of pure red cell aplasia with haematologic malignancies is rare. There are very few case reports on pure red cell aplasia with hepatitis C.
