Chronic Lymphocytic Leukemia: A Diagnostic Case Study

Wed, 22 Apr 2026 09:00:01 +0300

The patient was admitted for further examination and diagnosis.

He considers himself ill for about a month, when he began to experience fatigue, tiredness, and severe sweating, but continued to work and did not seek medical attention. He began to be examined in early April 2026, with leukocytosis up to 500x10*9/L in the complete blood count, lymphocytosis of 98%, total spleen area of 98 sq cm on abdominal ultrasound, abdominal lymphadenopathy up to 3 cm, and enlargement of submandibular, cervical, supraclavicular, axillary, iliac, and inguinal lymph nodes up to 2-3 cm.

Acute Myeloblastic Leukemia Without Maturation (FAB M1)

Tue, 21 Apr 2026 18:00:00 +0300

A patient with suspected acute leukemia. A complete blood count was performed, and the diagnosis was confirmed.

Marked leukocytosis was noted, with more than 90 percent of cells being myeloblasts. The picture corresponds to acute myeloblastic leukemia without maturation, variant 1 according to the French-American-British classification.

Blasts in Peripheral Blood Smear with Pancytopenia

Blasts🔬

A patient was admitted to the emergency department. Complete blood count results: HGB -55; PLT- 41; WBC- 2.1. When counting the differential white blood cell count, 19% blasts were found!

Acute Lymphoblastic Leukemia: Cytochemistry and Blast Morphology

Fri, 10 Apr 2026 10:00:01 +0300

TRILINEAGE cytopenia in a 75-year-old patient. Bone marrow aspirate shows total blast infiltration. The cytoplasm is basophilic with vacuolization. Myeloperoxidase reaction in blasts is negative. PAS reaction is positive in granular form. The morphocytochemical characteristics correspond to lymphoid lineage – a picture of acute lymphoblastic leukemia.

A child was admitted to the emergency department of a hospital. A 14-year-old girl. Leukocytes - 172. Platelets - 84. Hemoglobin - 111. Blasts - 95%. The child was transferred to the oncohematology department of another institution.

Acute Myeloid Leukemia: Blasts and Auer Rods in Blood

⚠ 97% blasts and Auer rods

Female, 75 years old.

🔬 Complete Blood Count:

Leukocytes — 181.76 ×10⁹/L
Erythrocytes — 2.84 ×10¹²/L

Myeloperoxidase Staining in Myelomonocytic Leukemia

Thu, 15 Feb 2024 13:00:00 +0300

🔬❗Staining of bone marrow aspirate — with benzidine manufactured in 1974. We decided to check if it would still work… And imagine, it works!

The diagnosis for a 35-year-old man is acute myelomonocytic leukemia (verified by flow cytometry - MPO+).

Acute Monocytic Leukemia M5b: Cell Morphology and Immunophenotyping

Mon, 21 Aug 2023 18:45:00 +0300

A case of diagnosing 500,000 leukocytosis!

After processing a blood sample from an outpatient clinic (male, 71 years old) and obtaining this result, doubts arose about its reliability: Leuk. 503×10⁹/L (the analyzer’s cell distribution across all possible channels only added to the uncertainty), Hgb 85 g/L, Platelets 196×10⁹/L. We repeated the analysis, while a smear was prepared and the patient’s history was reviewed. The result was repeated, and in June 2022, the patient was diagnosed with Diffuse Large B-cell Lymphoma of the soft tissues of the back. He underwent chemotherapy. At present (end of July 2023), we have no clinical data.
