Pathology in black and brown skin

I’m looking for a good textbook or other resource on how pathologies and clinical findings present in Black and brown skin.
I’m a massage therapist currently in nursing school, and I’ve seen little to no examples of melanated skin in my textbooks, lectures, or study materials. I’m specifically looking for resources that show how things like rashes, inflammation, cyanosis, erythema, bruising, pressure injuries, etc. can present differently on darker skin tones.
I’ve been searching everywhere and haven’t found a resource that quite fits what I’m looking for. I’d really appreciate any book, textbook, website, or other resource recommendations!
Also, is anyone here currently working on improving representation of darker skin tones in medical education? I’d love to learn more about what’s being done.
