What's the worst misdiagnosis you've seen happen?

I haven't seen any cases of misdiagnosis, that is, there was a classmate, she wasn't feeling well for a while, and then her period didn't come yet, she said she needed to go to the hospital to have a look at it, and she was supposed to go to a tertiary hospital, but the report could not be obtained until the next day. And she was in a hurry, so she went to a nearby private hospital, and as a result, the doctor said she was pregnant. It happened to be her mom who accompanied her there, and her mom slapped her directly when she heard the result.

Because she was only in high school, she then kept explaining, but her mom didn't believe her, and she went to ask the doctor if it was a misdiagnosis, and the doctor swore that the report was definitely not wrong, and that you were pregnant. When she got home, her mom scolded her again. She was furious and went to another hospital the next day for a checkup, and when she got the report, the doctor said there was no big problem, and that her aunt didn't come because of stress, and that there was no sign of pregnancy at all.

Seriously, she cried at that time, and when she went home and told her about it, her mom kept scolding that doctor for being clueless. This is a more serious misdiagnosis that I have personally seen, to be honest, when I heard about this matter, I think the doctor is too ridiculous, is not without learning medical skills directly on the job, this should be considered a relatively simple diagnosis, can be misdiagnosed, is really not to say.

It must be said that in reality there are still some other misdiagnosis of more serious things, some serious may lead to the death of the patient, so that this is really very terrible. So we go to the hospital to see a doctor, it is best to go to a professional reliable hospital, in this case the heart is solid, after all, the misdiagnosis of the situation is not particularly much.
