Cyst Disorders - are they related?

Factual Questions
1

I was just looking up something about cysts (ugh, awful. Try to avoid that.) and it occurred to me that I personally suffer from several disorders related to cysts. Polycystic ovarian syndrome, pilonidal cyst (removed), cystic acne and hidradentis supperativa (cysts in unpleasant places).

I suspect the last two are related to hormones and sebum production. Not sure if the pilonidal cyst is related to hormones but is related to sebum. The PCOS is related to hormones but not sebum.

Are all of these ailments related to each other or is it just a coincidence that all my chronic issues have “cyst” in their description?

It’s my understanding some people are just cysty shudder
Having polycystic kidney disease, there’s a high chance I will have polycystic liver disease, a possibility of PCOS, and I’ve been told (upon removal of a few cysts on tendons in my wrist) that they will just show up anywhere they damn well want.
