Sorry Bev, I've just been SWAMPED!!! sick too....PERFUME ATTACKS!

Bev, your doctor is right, there are so very few reports done on the esophagus that it's hard to say that this would be considered anything more than eosinophilic eosophagitis. However, this is pretty often seen in masto patients, so he's right on the nose.
Now, what they need to do is run you through those endoscopes again and this time go back through with A GREAT DEAL MORE CARE taking more biopsies within that one section where you are showing this trouble. Then it must be all submitted for the APPROPRIATE TESTS!! There are specific markers for testing for the immunohistochemical testing and the best stains are giemsa, toludine blue and tryptase with tryptase being considered the best. If then there are any focal points of MC aggregates, this is what shows how the MC are whether they are clonal or normal. However, these tests should also be sumitted for genetic testing to see if there are any genetic defects upon those MCs. This would give a much clearer picture of your case then.
My son has eosinophilic enterocolitis, it's in his colon. He had very elevated levels of normally shaped loose MCs, however, they managed to find ONE FOCAL POINT OF AGGREGATED MCs!! It proved he has mastocytosis. However, he could not be diagnosed with mastocytic eosinophilic enterocolitis because there was only ONE focal point of aggregates and not 20! The 20 would then fulfill the diagnosis of mastocytosis - they have the official criteria and without fulfilling that specific criteria it throws his diagnosis over to MCAS. Understand?a
But what's the basis of your questions, really? Do you have the more dangerous form of SM? NO! TMEP is indeed a form of cutaneous mastocytosis, but does it mean it's systemic yet, not necessarily. Does it mean it's dangerous, definitely not! How do we know? Look at your CBCs and your tryptase levels.
If your CBCs are showing signs of alterations, this could be due to the masto and it needs checking. If your tryptase levels are elevated or increase, then this is what reflects the MC burden. If either of these are altered, then a BMB should be done in order to check if the masto has gone systemic.
However, do these tests influence your treatment? Depends. If your tryptase is not sky high and your CBCs are nice and pretty, then the answer is NO!! However, if there are alterations, then your doctors have to evaluate your case and see if there are needs for other changes requiring more intervention.
Yet, Bev, if you don't have doctors jumping all over you and doing flip flops and looking like this

, then CALM DOWN and BE AT PEACE!!! You're not in any real danger!! You will likely die from anything else but masto and only when you're a old lady!!

I hope this helps you!
Hugs
