hi doctor, what a pleasure to finally read someone who talks about my illness. i discovered this disease on my left temporal artery in 2016 when i was dying from a concomitant problem with a kidney failure due to glomerulonephritis. It was terrible, having spent months in the hospital and then years with relapses and with a very young daughter with me. At first the temporal artery biopsy resulted in Kimura Syndrome but later confirmed it was Angiolinphoid Hyperplasia with eosinophilia. I took cortisone and immunosuppressants but nothing! I neither solved nor improved. I then continued my research with some trusted doctors, and I approached the use of natural anti-inflammatories that allowed me to continue a normal and healthy life, also reducing anxiety, which however remains partly due to the darkness around this disease, its course and its disorders. In Italy this disease is not talked about and nothing is understood. Happy to have at least found this video so clear (histologically). I would like to know if there are effective treatments? I notice a worsening during the menstrual cycle ... but no doctor listens to me in Italy. I would like to find people who suffer from it to confront us and doctors prepared like you . Also abroad. Thanks so much. I hope you can help me.

It must be something in your voice but my 1.5yr old is happy sitting on my lap and watching your videos with me!

[@JMGardnerMD]

I’m happy I can help! As a dad of 3 young daughters, I know how valuable it is to have the kids calm and quiet!

Dear Jerad thanks for sharing your experience in such a nice way and being such a great teacher. I find myself referring to your work when I get stuck.

[@guilldrmobritos3551]

Excelente video ricamente ilustrado y con una descripción histológica ejemplar. Es como estar leyendo un libro. Gracias

[@JMGardnerMD]

De nada, amigo! Y muchas gracias por las palabras amables!

[@guilldrmobritos3551]

@@JMGardnerMDDe nada, empecé a ver los vídeos y son adictivos. A veces el inglés es muy rápido y me pierdo algunas palabras por lo que tengo que rebobinar la presentación. Pero es un detalle menor en relación a todo lo valioso que aprendo. Soy un patólogo de 60 años y nunca es tarde para seguir aprendiendo. Mil gracias por tus esfuerzos

[@JMGardnerMD]

Lo siento. ¡Hablo muy rápido! claro! jejeje 😂 Algunos videos tienen subtítulos en inglés. Quiero crear más subtítulos en el futuro. ¿Son útiles los subtítulos?

[@hagarkhallaf991]

This is awesome Thanks a lot dr. Jerad

[@cmtati]

Another outstanding presentation

[@LOLsaudi]

Should be ordering c-myc to all post radiation vascular lesions :) thx for the great video Dr.Jared.

[@JMGardnerMD]

I don’t always order c-myc. Depends on the situation, how big the biopsy is, and what the clinical appearance is.

[@chiomaede9937]

Very good teaching right there, thanks

[@ahmedtouni9136]

Great as usual ,waiting for more and more

[@niallicious]

Thanks I learn so much from very video particularly with the range of cases you show. I would love to see an angiosarcoma/Kaposi's sarcoma video using slides or pathpresenter.

[@JMGardnerMD]

kaposi sarcoma video by me & @globaldermie: kzbin.info/www/bejne/bYSXdKKVqayJe6s

[@MaleeMish]

Fantastic video, thank you!

[@hagarnofal2037]

Thanks! a very nice & informative video :)

[@bushrasikandar9367]

Great video, but I guess there is some confusion between anastomising hemangioma vs retiform hemangioendothelioma. Plz share clues to differentiate them

[@JMGardnerMD]

Retiform is infiltrative. Anastomosing is well circumscribed. Here’s my video on anastomosing hemangioma. kzbin.info/www/bejne/qmXGmmN_Z56rnMk

[@azzaal-helo5300]

You R amazing ....

[@pavelboico9283]

After watching so many videos about benign lesions, may I ask this question? Do you think average Joe pathologists have a tendency to overestimate malignancy? For legal reasons, for example. Is this a thing in your field? Kind regards from international viewer.

[@phimedia3895]

Thank you sir🙌

[@panjitchieosilapatham4272]

Thank you so much

[@TheProjectHenryD]

Hi, I think I have one of these on my leg, should I be worried about it? Had it for a few years however it sometimes it can be gone for a few months, then it would come back ect

[@JMGardnerMD]

Please see a board certified dermatologist for an examination. They can take a look and decide if your skin lesion is something worrisome and if a biopsy is needed or not.

[@reoni6499]

Thank you for a great lecture! Can you use SMA to differentiate benign hemangioma from subtle angiosarcoma? Would SMA be negative in angiosarcoma? Thanks!

[@JMGardnerMD]

Great question! Theoretically yes. Many angiosarcomas lose their layer of pericytes. And most hemangiomas retain it. But I’ve seen exceptions both ways. Nothing is perfect unfortunately!

[@reoni6499]

Thank you so much! Really learning a lot on your channel! 👍👏
