If you needed an image for what angioinvasive and angiodestructive lesions look like in an NK/T cell lymphoma, here it is. Lethal midline granuloma is also fun to say.

Low-grade follicular lymphoma invovling the bone marrow, with a diffsue and homogeneous CD5 expression by stain (below) and flow cytometry analysis, with diffuse BCL2 (below), BCL6 and CD10 expression and BCL2 rearrangement by FISH. Another reminder to do a full low-grade

Interrupting your #ASCO25 feed with 3 👌🏼 #hemepath cases from last week’s sign-out 🔬 🧵 1. R/R AML with unusual morphology, small primitive blasts, stromal fibrosis and marked proliferation of micromegakaryocytes (blue arrow head)

BMB 80 yo female with fever and weight loss. 5.4K lymphocytosis. BM flow shows kappa restricted B cells negative for CD5/10/23, positive for CD200 consistent with MZL. Now look at the bx 🙈 2nd pic is the green arrow HPF, 3rd pic is the orange arrow HPF. Diagnosis?See comments

📌 CD30-Positive Tumors: What Pathologists Should Know 🔬 CD30 is a transmembrane protein of the TNF receptor superfamily, physiologically expressed in activated B and T cells. In neoplastic contexts, CD30 expression is significant in several lymphoid malignancies, with

New academic year & I’d love for every PGY1 #pathology resident to recognize acute monocytic leukemia 🔬 🌟 sky :common in monocytic AML (⬆️ cell turnover) if U’re like me, old-fashioned &still into #FAB: this is M5b (with maturing monocytes) #hemepath

FIVE Fascinating Facts About Auer Rods Auer rods are more than just pink needles in blasts. A thread…🧵

Hot news - Epcor + R2 superior to R2 in RR follicular lymphoma. Overall response and PFS (HR 0.21). Hoping for a quick license and NICE approval. #lymsm

Seems wrong to have personally diagnosed 6 new Hodgkin in under 5 days…the math is not right. Most were nodular sclerosis. One lovely lymphocyte-rich #hemepath:

Throwback to an early 90s hit...I like big cells and I cannot lie. I'm hooked and I can't stop starin'. Oh, baby, I wanna get with ya. And take your picture... Guess what the big cells are in this marrow? Substantial clue in followup post. #hemepath
