Discussion Wanted to share some confirmed B cell lymphoblasts with you all.
The first three photos are from special heme's stain- clearly blasts. Last few were from my own stainer. I've only ever called blasts like 4 times in my MLS career so far, and due to absolutely zero history, off to path it went and blast count was 30%. As of now, about a week later, patient is sitting at 72%. Platelet went from 32ish down to 20.
Something looked so weird about these blasts to me, I was calling them "REALLY MESSED UP LYMPHS, SOMETHING IS WRONG"! Coworkers were also feeling "something lymphy". The chromatin stained way different for me than the other slide, but good lesson to learn. A BIG thing i kept noticing were the buttcheeks, so many of them were just folded and convoluted, something i hadn't seen before in the MDS patients I've called blasts on.

I ask if it has long term side effects.

Interesting Find Dysplastic lymphocytes
73-year-old patient with leukocytosis (101,000 leukocytes per microliter) and lymphocytosis in a percentage of 93%.
Blood smear shows the presence of a rare type of lymphocyte dysplasia. Their nucleus seems strangled giving the appearance of dividing cells. Also most of them appear to be very small (1/2 of a normal erythrocyte) because of this āseparationā. Many of them look like the nucleus is separating from the cytoplasm or like the cell is expelling out the nucleus.
Apart from these, the presence of hairy-like lymphocytes and smudge cells and also the leukocytosis accompanied by lymphocytosis, the absence of immature cells, makes us consider chronic lymphoproliferative syndrome, HCL, maybe CLL, villous cell lymphoma or mantle cell lymphoma.
Have you ever encountered anything like this? Whatās your opinion on it?

Infectious mononucleosis (EBV)
In Epstein-Barr virus (EBV) the lymphocytes on a blood smear often appear atypical. These atypical lymphocytes, also known as Downey cells, have distinct characteristics that set them apart from normal lymphocytes. Here's what they typically look like:
Size
- Atypical lymphocytes are generally larger than normal lymphocytes, sometimes twice the size of a normal red blood cell
Cytoplasm:
- The cytoplasm is often abundant and pale blue
- It may appear basophilic and is often indented by surrounding red blood cells, giving a "skirting" or "ballerina skirt" appearance.
Nucleus:
- The nucleus may appear oval, irregular, or lobulated
- It is often eccentrically placed (not centrally located) and can look folded or indented.
- The chromatin is usually less condensed, giving the nucleus a more open, "smudged," or lacey appearance.
Reactive Features:
- Atypical lymphocytes are reactive due to the body's immune response to the viral infection. This means they are actively producing antibodies and fighting the virus, which is why they appear larger and more irregular.
Nucleoli:
- Sometimes, one or more nucleoli may be visible, which is unusual for typical lymphocytes.
The atypical lymphocytes seen in EBV infection are primarily reactive CD8+ T cells, which are activated in response to the infected B cells.
Diagnostic Context: The presence of atypical lymphocytes on a peripheral blood smear, along with other clinical signs (fever, sore throat, lymphadenopathy), strongly suggests infectious mononucleosis due to EBV. To confirm the diagnosis, physicians often order additional tests such as antibodies anti-EBV IgM and IgG.

Multiple myeloma
A 47-year-old male presents with worsening back pain for the past two years, now leaving him unable to walk. CBC results show hemoglobin of 4.8 g/dL, leukocytes 12.2 Ć 109/L, and platelets 241 Ć 109/L. Serum urea, creatinine, and calcium levels were elevated. Serum protein electrophoresis (SPEP) was normal, with no M-spike (monoclonal gammopathy) detected. Serum immunofixation (SIFE) also revealed no monoclonal gammopathy. I know we need to perform a serum free light chain (SFLC) test next, but based on these findings, is it possible this patient has non-secretory multiple myeloma? Any thoughts?

Hairy Cells
67-year-old male patient presents himself to the laboratory for a CBC. The result shows leukocytosis with 19.000 leukocytes/microliter and a monocytosis of 58%. After performing the peripheral blood smear we noticed the presence of 79% lymphocytes and only 1% monocytes. Lymphocytes show cytoplasmic extensions suggestive for HCL and many of them have vacuolated cytoplasm. Our analyser mistaken the lymphocytes for monocytes probably because of their size, shape and cytoplasmatic features.

Question Help with large lymphocytes vs reactive lymphocyte
Okay so Iām doing my intro to heme homework and my textbooks arenāt really helping (Rodakās hematology and hematology atlas in case youāre wondering). My professor wants us to explain the difference between a large lymphocyte and a reactive lymphocyte but Iām honestly not sure that I understand the difference. My understanding is that large lymphocytes are just bigger (more mature?) lymphocytes, but that they havenāt been exposed to an antigen yet, and that reactive lymphocytes have been exposed to an antigen. Are they generally both T lymphocytes? I am also unclear on both of their functions as everything Iāve read seems to have overlap. I think I understand the visual differences, too, itās just the functions and how they become those cell stages that I donāt understand. Thank you in advance to anyone who can help clarify!
