Check out the peculiar vacuolated cell change in this banal fundic gland polyp. This change, possibly related to proton pump inhibitors, sometimes results in concern for in situ signet ring cell carcinoma, which appears different (the high magnification image).

Langerhans cell histiocytosis (LCH) can present as colorectal polyps in adults and is generally indolent - analogous to to eosinophilic granuloma. Pediatric gastrointestinal LCH, in contrast, is often devastating. pubmed.ncbi.nlm.nih.gov/3889…

I’d like to start this day with something positive. But Russia just hit a school in Kyiv. The kids were in the shelter.

"Los Rojos invaden Polonia" "Rusos cruzan la frontera para proteger a las minorías" 87 años de diferencia, mismas excusas
Putin: "Rusia sabe que los derechos de los hablantes de lengua rusa son violados en los países bálticos" Mismo discurso que en Ucrania, mismo discurso que en Georgia, y quien sabe si mismo discurso que en Torrevieja dentro de unos años

Russia has struck central Dnipro in broad daylight. ❗️A large business center is on fire, cars have been shattered, and people are reportedly trapped inside. There are casualties. This is happening in the middle of the day, while people are simply at work. ‼️Russia continues its attacks on Ukraine 24/7. It targets offices, shopping malls, markets, and educational facilities daily. It must be held accountable for these attacks.

A Russian strike against the building of the National Academy of Sciences of Ukraine. A rescue operation is underway: crews are putting out the fire and searching for people who may have been trapped inside. All services are deployed. Today in Kyiv, a pharmaceutical company and gas stations were also attacked; in Dnipro, a business center; and in other cities and regions, civilian facilities, businesses, and communications infrastructure were targeted as well. Sadly, people have been killed… My condolences to their families and loved ones. Russia will definitely face a response to this. And every one of Ukraine’s partners must see from this terror, from these strikes, that supporting Ukraine means truly supporting people’s lives – supporting the principle that terror must never be normalized, anywhere. Russia must be held accountable for all of this and face real consequences. I thank everyone who helps Ukraine!

russia is systematically destroying European science and cultural heritage sites. They literally just hit this 19th century historic building in central Kyiv. It’s the headquarters of Ukraine’s National Academy of Sciences. Deplorable.

A striking case of histoplasmosis. It really is nasty about mimicking Crohn's disease.

Russia intentionally bombs libraries, they destroyed 9 million books in Kharkiv recently. Burning books has nothing to do with ‘territory’. Nazis did exactly the same thing for the same reason. To erase history.

russian drone operator deliberately aims a civilian in Kherson. I just have no words for this…
Today, many were shocked by yet another video of the drone “safari” Russians are carrying out against civilians in Kherson. A Russian drone deliberately hunted down a man selling vegetables and detonated right next to him. The Russians even admitted to the crime, showing zero regret and openly boasting about tormenting people. The man was wounded in the blast. Every single day, ordinary people in Kherson face these Russian "safaris." The world must see this. It must see every piece of evidence that Russia has gone mad and that its soldiers take pleasure in killing and abusing civilians. Without pressure on Russia, the dismantling of its capacity for aggression, and real security guarantees, it is simply impossible to imagine the world being able to coexist with this evil. We must remain resolute in defending life. We must act and support life in ways that force Russia to seriously think about peace rather than expanding the range of its drones. This is not just about Ukraine. Russia’s campaign against human life must be stopped here in Ukraine before it spreads further. Finland and Kazakhstan, the Baltic states and Poland, the countries of the South Caucasus, Romania, and Moldova—all should work together to ensure real security guarantees and bring Russia’s war to an end. Peace is needed, which requires cooperation among everyone in the world who truly values peace. Thank you to everyone standing with Ukraine!

Overnight, Russia carried out one of its largest ballistic missile attacks on Kyiv. The enemy launched more than 40 missiles of various types – most of them against the capital – and 120 attack drones. As of now, one person has been reported killed in Kyiv and the region, and 16 others have been injured. My condolences to all their families and loved ones. Everyone affected is receiving the necessary medical care. Emergency response efforts are continuing at three locations, with nearly 600 first responders involved. The relevant services are also working in the Odesa region. In total, over the course of this week, Russia has used around 1,450 attack drones, more than 1,640 guided aerial bombs, and 99 missiles of various types against Ukraine. People were injured in the Odesa region and Zaporizhzhia, and there was damage in the Sumy and Chernihiv regions. This week, the Vinnytsia, Dnipro, Donetsk, Zhytomyr, Kirovohrad, Mykolaiv, Poltava, Kharkiv, Kherson, and Cherkasy regions also came under Russian attack. Protection against ballistic missiles is our constant and top priority right now. Interceptors are needed every day, and I am grateful to everyone who takes our agreements seriously and ensures the delivery of anti-ballistic capabilities. Right now, these packages are literally saving lives during every massive Russian attack. It is also essential that pressure on Russia continue alongside our work on anti-ballistic capabilities. Delays in adopting new decisions give Moscow the opportunity to plan not only new attacks against our people, but also ways to circumvent new sanctions. Thank you to everyone who is helping.

To all those politicians who claim that military aid for Ukraine should not be given, so that put this war to its end: just come to Ukraine (e.g. to Kyiv, Odesa, Kharkiv, Zaporizhzhia) and witness russian atrocities with your own eyes. Then you’ll probably understand something.

If russia stops attacks and withdraw troops, the war will end. If Ukraine stops defending itself - Ukrainians would be slaughtered. It is simple: if one wants aggression to stop, one should confront the aggressor, not blame or sacrifice the victim. #stoprussia #russianwarcrimes

Some terrifying photographs coming out of Kyiv tonight. The barrage by Russia was over 30 missiles strong.
