Early response and outcomes of bone marrow to chemotherapy in T-Cell Acute Lymphoblastic Leukemia.

Objectives: To evaluate the outcomes (relapse and mortality rate) and response of the bone marrow in early stages after combination chemotherapy in patients with T-cell Acute Lymphoblastic Leukemia (T-ALL).

Methods: A descriptive cross-sectional study was conducted at King Fahad Medical City, from January 2021 to December 2022, to evaluate bone marrow findings at the time of diagnosis and post-chemotherapy in 26 patients diagnosed with T-ALL. The study included all patients diagnosed with T-ALL of any age group during the study period.

An unusual non-hematopoietic bone marrow finding.

We present an interesting case that showed a non-hematopoietic structure embedded in the bone marrow biopsy. Given the clinical and morphological difficulties, it was challenging to identify this artifact's nature. Publishing this case would familiarize pathologists with this artifact and save additional testing and delays in reporting.

Flow Cytometry Analysis Versus E-Cadherin Immunohistochemistry for the Diagnosis of Pure Erythroid Leukemia: A Case Report.

Pure erythroid leukemia (PEL) is a rare form of acute myeloid leukemia characterized by the neoplastic proliferation of erythroblasts. PEL is associated with inferior survival outcomes, particularly among patients harboring complex karyotype abnormalities. In this case, we present a 21-year-old Sudanese man who presented to our ER with a two-week history of fever, shortness of breath, fatigue, and exercise intolerance.
