Yep, a pathologist can prescribe just like any other doctor.
Not much patient contact with dermapath unless you are a dermatologist that is also derm path certified.
Surg path does not have much patient contact either.
Cytopath has lots of patient contact for fine needle aspirations. But, in a consultant role not as a primary care giver.
Apheresis which is part of clinical path has some long term patient contact and short term consultant contact.
Heme path has consultant contact for bone marrow aspirations, though most are done by heme onc docs. (Except at my program we do almost all of them in the hospital)
