Philadelphia chromosome detection in chronic myeloid leukemia: Utility of phytohemagglutinin-stimulated peripheral blood culture
No full textBackground: The conventional cytogenetic approach to demonstrate Philadelphia (Ph) chromosome at times does not yield enough number of metaphases or are of suboptimal quality. Further, the rapid molecular tests have completely pushed this simple technique into disrepute. Aims: This study aimed to evaluate usefulness of phytohemagglutinin (PHA)-stimulated peripheral blood culture for detection of Ph chromosome in chronic myeloid leukemia (CML) patients. Materials and Methods: Fifty-six patients, including 11 newly diagnosed cases of CML and 45 patients of CML on imatinib therapy showing the presence of Ph chromosome in unstimulated samples, were included in the study. Cytogenetic analysis was done on unstimulated samples, i.e. bone marrow aspirate, 24- and 48-h peripheral blood culture, and compared with PHA-stimulated 72-h peripheral blood culture. Results: The preparations from PHA-stimulated peripheral blood culture samples in all 56 patients yielded high number of good-quality metaphases. All the 11 (100%) newly diagnosed patients and 39/45 (87%) of the patients on imatinib therapy showed the presence of Ph chromosome in PHA-stimulated samples. Addition of PHA-stimulated 72-h peripheral blood culture preparation can be of use for increasing the diagnostic yield in cases of CML with suboptimal results on conventional cytogenetics from bone marrow aspirate sample
A young leukemic patient with unusual catastrophic intestinal complication
No full textA 14-year-old child with acute lymphoblastic leukemia who had completed induction chemotherapy presented with fever and diffuse musculoskeletal pains which was thought to be a constellation of myositis, arthralgias and arthritis. Investigations revealed initially showed normal peripheral blood counts but had pancytopenia and pre-terminally blasts were seen in the peripheral blood smear. He had bone marrow necrosis. Disseminated intravascular coagulation was suspected with a positive fungal serology. At autopsy, he had evidence of disease relapsed in lymph nodes, liver, spleen, testes and kidneys. There was extensive pseudomembranous colitis and appendicitis with changes of toxic megacolon

Chronic lymphocytic leukemia developing in a case of chronic myelogenous leukemia - accelerated phase: A rare case with review of the literature
No full textChronic myelogenous leukemia (CML) and chronic lymphocytic leukemia (CLL) are two different and common hematological neoplasms. Their coexistence is rare, especially CLL developing in a patient of CML. Till date, only a few cases are reported and all had chronic myeloid leukemia - chronic phase earlier. We report the first case of CLL developing in a patient initially diagnosed in an accelerated phase of chronic myeloid leukemia. The clonality of both CML and CLL was proven by cytogenetic, molecular and flow cytometric studies
