Disseminated porokeratosis anyone?

I have chronic itching perhaps from multiple illnesses, but increased with covid vax. Recently diagnosed with diabetes. I have such dry skin there is a layer of dust everywhere. It even affects my cat. Went to a cream for itching and there was nothing said about that or dry skin. Did a punch biopsy of an eraser sized lesion on my knee and was diagnosed with disseminated porokeratosis, a precancerous type of annoyance. I have read that you can get hundreds of these and there is no cure. It mostly affects women over the age of 50. There’s a genetic component (although no one in my family had it) or often people who have immune issues (that’s me).

Ok. Anyone have any experience with disseminated porokeratosis? Most interested to hear from someone. Thanks.
