Conversion of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma to Angioimmunoblastic T-cell Lymphoma: a Rare Case.

Background: Angioimmunoblastic T-cell lymphoma (AITL) is a distinct subtype of peripheral T-cell lymphoma (PTCL) and accounts for 2% of all non-Hodgkin lymphomas. Its typical characteristics include an aggressive course, progressive lymphadenopathy, hepatosplenomegaly, systemic symptoms, anemia, hypergammaglobulinemia, and generally poor prognosis.

Methods: We describe a rare case in which the left inguinal lymph node was completely excised and biopsied one year ago.

Clinical significance of detection of mononuclear phagocyte subsets in blood and bronchoalveolar lavage fluid (BALF) in pulmonary sarcoidosis.

This study aimed to investigate the clinical significance of the detection of mononuclear phagocytes subsets in pulmonary sarcoidosis blood and bronchoalveolar lavage fluid (BALF). For this purpose, a total of 52 patients with pulmonary sarcoidosis were selected as the study group, 52 healthy people served as the "NC Group a" (peripheral blood mononuclear cell control group), 47 patients with chronic cough and no pulmonary sarcoidosis who underwent bronchoscopy were used as "control group b" (alveolar lavage fluid macrophage control group). Fasting peripheral blood and BALF were collected, and flow cytometry was used to detect monocytes and macrophage subpopulations.
