Well we never even got to the endoscopy. They diagnosed a mast cell tumor on her shoulder under a large scar. I noticed the lump several weeks ago, but assumed that it was scar tissue from a poorly sutured previous wound. Because GI bleeding can be associated with MCTs, we decided to go ahead and stage it by getting thoracic radiographs, an abdominal ultrasound, and liver and spleen aspirates. The thoracic rads were clear, the only abnormality they found on U/S is a splenic nodule which they think had the appearance of a benign nodular hyperplasia. So now I'm anxiously waiting on the liver and spleen cytology. There are three possible outcomes:
1. Come back normal: we'll have the surgical oncologist remove the mass with wide margins.
2. Come back inconclusive: still have it removed, continue to monitor with abdominal ultrasound, etc
3. Come back with disseminated mast cells: consult with oncology department for chemo
This is not the news I thought I would get today.
