I had this problem the other day with no scrollbar showing up when the content of my App Part was larger than the iframe.
It turned out to be the /_layouts/15/1033/styles/themable/corev15.css that was the reason. This file is included on my App Part aspx page, in order to get the same style as the rest of the site.
The simple solution to the problem was just to add a style tag with overflow to the body tag on the App Part aspx page.
<body style="overflow:auto;">
Result:
If you wanner resize from your iframed page, its possible by use of the postMessage command.
Found on the forum posted by Yina Arenas
<script type="text/javascript">
window.onload = function () {
var target = parent.postMessage ? parent : (parent.document.postMessage ? parent.document : undefined);
var regex = new RegExp(/[Ss]ender[Ii]d=([\daAbBcCdDeEfF]+)/);
results = regex.exec(this.location.search);
if (null != results && null != results[1]) {
target.postMessage('<message senderId=' + results[1] + '>resize(500,200)</message>', '*');
}
}
</script>

Excellent piece of code but few things missing. Assign results as a var. Otherwise it will throw an error.
Thanks for this great article. Really well written. Thanks for sharing.
