Diffuse large B-cell lymphoma in a patient with chronic myelogenous leukemia on accelerated phase with bilateral pleural effusion: a case report
Chronic Myelogenous Leukemia (CML) is a myeloproliferative disorder of pluripotent stem cells. The pathogenesis of CML is known to be related to mutations in the form of Philadelphia chromosomes. The incidence of CML constitutes 20% of all cases of leukemia in adults. The current gold standard for CML therapy is using tyrosine kinase inhibitors (TKI), Imatinib. Non-Hodgkin Lymphoma (NHL) is a malignancy that develops from lymph nodes. In NHL the formation of malignant cells is in the form of lymphocytes that are at one of the differentiation levels of either T lymphocytes or B lymphocytes. Diffuse large B cell lymphoma is the most common NHL, representing about 40% of all lymphoma cases. NHL management is targeted chemotherapy using rituximab combined with cyclophosphamide, doxorubicine, vincristine and prednisone. A Thirty-four year-old female patient has been reported with the main complaint of fatigue and pale weakness accompanied by an enlarged abdomen. Complaints are also accompanied by a lump in the right neck, fever, productive cough and shortness of breath. The patient has been known to suffer from CML with BCR-ABL (+) since five years ago and received Imatinib therapy, but then the patient stopped treatment himself. On physical examination found anemic, multiple enlargement of the neck lymph nodes, wet crackles soft and loud in the basal of both lungs and splenomegaly. On investigations found severe anemia, thrombocytopenia and blast 13%, increased d-dimer, bronchopneumonia-compliant infiltrate and bilateral pleural effusion on chest x-ray, results of exudate pleural fluid analysis with the cytology of a malignant smear metastasis of lymphoma to the pleura, histopathology of the neck lymph nodes with chest x-ray, analysis of exudate pleural fluid with the cytology of a malignant smear metastasis of lymphoma into the pleura, histopathology of the neck lymph nodes with the results of diffuse large B-Cell lymphoma, as well as enlargement of paraaortic lymph nodes, hepatosplenomegaly and chronic pancreatitis on abdominal ultrasound. Patients was given antibiotics, transfusion of packed red cells and platelets, pleural tap and chemotherapy. The patient was planned to undergo chemotherapy for 6 cycles of 21 days, and a CD20 examination was performed. The incidence of NHL in patients with good CML in imatinib therapy is not yet certain whether there is a direct relationship
Essential Thrombocythemia in Young Women
Background: Essential thrombocythemia (ET) is a rare disease in which there is an increase in the platelet count of more than 450,000/mm3. An increase in the number of platelets occurs due to increased proliferation of megakaryocyte series. Although there is an increase in the number of platelets in ET, it has impaired function. ET clinical manifestations in 50% of cases are asymptomatic, but in symptomatic cases can be vascular occlusive events or microvascular thrombosis.
Case presentation: A 22-year-old woman with complaints of rash on the hands and feet. Physical examination found an enlarged spleen in Schuffner 1 and ecchymosis on the arms and legs, a platelet count of 811,000/mm3. The peripheral blood smear shows large platelets, the bone marrow picture shows megakaryocytes, which are very easy to find, the size varies with sufficient platelet emission, the JAK2 gene mutation examination shows mutation detection, while the BCR-ABL gene mutation results do not detect gene fusion. Treatment is given cytoreductive therapy in the form of hydroxyurea, while acetylsalicylic acid is not given because there are contraindications for administration.
Conclusion: Essential thrombocythemia is a neoplastic proliferative disease that occurs in the megakaryocyte series. The diagnosis of ET mostly found mutations in the JAK2 gene. ET management according to risk classification, where acetylsalicylic acid can be given very low and low risk, while intermediate and high risk can be given cytoreductive therapy
Atypical Chronic Myeloid Leukemia in Pregnancy
Background: Atypical chronic myeloid leukemia was first depicted as a subtype of myeloid neoplasm that closely resembles chronic myeloid leukemia but does not have the pathognomonic Philadelphia chromosome. Chronic myeloid leukemia can also be found in pregnant and fertile women, which means pregnancy can happen at the time of diagnosis or during the treatment of this disease.
Case presentation: A 32-year-old woman came to the hemato-oncology polyclinic at M. Djamil General Hospital Padang with the main complaint of weakness and fatigue. The patient was pregnant with a gestational age of 23-24 weeks. On physical examination, the conjunctiva was anemic, and the spleen was palpable S4 (18 cm). On routine blood laboratory examination, the results of anemia, leukocytosis, and on the peripheral blood picture, severe normochromic normocytic anemia was found with pathological cells of 3% myelocytes and 1% metamyelocytes. Conclusion bone marrow puncture (BMP) results follow the description of chronic myeloid leukemia in the chronic phase.
Conclusion: During pregnancy, chronic myeloid leukemia has a better prognosis compared to acute leukemia. However, atypical chronic myeloid leukemia still has the potential of leukostasis, causing uteroplacental deficiency and eventually leading to fetal growth restriction, premature birth, and an increase in perinatal mortality
