Advanced-stage high-grade B-cell #lymphoma (MYC-R with BCL2 and/or BCL6-R), single-centre series, n=124: 69 MYC/BCL2, 34 triple hit, 21 MYC/BCL6. Targeted NGS in 36.
CR 44%, 2-year OS 59.8%, CNS relapse 10.1%.
DA-R-EPOCH associated with better OS than R-CHOP-based therapy.
MYC/BCL6-R: more CNS relapse and rapid progression to death after relapse, with a different cell of origin from BCL2-R disease. Perhaps a place for novel agents - definitely looking for more cohorts treated with bispecific antibodies 1L in the coming years.

Just a bread and butter case: with better control of HIV disease it is easy to forget about Kaposi sarcoma - this example with hyaline globules. (erythrophagolysosomes).

This prostate tumor clearly read the literature: voluminous cytoplasm, pyknotic nuclei, and a histiocytoid appearance.
The adjacent benign glands show atrophic look with prominent basal cell hyperplasia.
What happened to this prostate?

Renal biopsy in a middle-aged woman with a known history of NSCLC. Clinical query: primary renal tumor vs. metastasis?
PAX8 shows weak nuclear expression 🧐
So, renal cell carcinoma or is there another diagnosis here? 🔬

Where does an expert look first on a slide?
The expert does not have better eyes, just a better sense of where to look first.
In a 2024 randomized study, 53 students learned histology from the same expert video.
Half also saw a live overlay of where the expert's eyes went.
That group recognized patterns better afterwards (d = 0.40).
When you teach at the microscope, say where you are looking, not only what you see.

Tiroiditis de Hashimoto, en The Lancet (2026). La causa más frecuente de hipotiroidismo. Puntos clave:
🔵 Anti-TPO positivo en 90%. Pero se miden una sola vez, no necesitas volver a hacerlo. Anti-Tg solo si anti-TPO es negativo.
🔵 Si es subclínico: tratar si TSH ≥10. Entre 4–10: individualizar (<65 años, síntomas claros, bocio o alto riesgo CV). COn TSH elevada + anticuerpos positivos progresan 5% por año a hipotiroidismo franco.
🔵 Dosis inicial de Levotiroxina: 1.4–1.8 µg/kg (menos en ancianos o cardiópatas), TSH a las 6–8 semanas; tras dos TSH normales separadas ≥3 meses, control anual. T4+T3 sin beneficio consistente.
🔵 Embarazo: eutiroidea anti-TPO+: sin tratamiento, solo vigilancia de TSH. Hipotiroidea conocida: meta de TSH de <2.5 antes de concebir y subir dosis 20–30% al confirmar embarazo.
🔵 Selenio baja anti-TPO a 6 meses, pero no mejora función, calidad de vida ni progresión, sin utilidad.
