👉 A psammologist is a psychologist who specializes in studying and diagnosing psoriasis, also known as lichen planus. They use various diagnostic tools to identify symptoms of psoriasis, including skin conditions such as psoriasis vulgaris or dermatitis scoliosis, which can be caused by a genetic mutation that affects the body's immune system. Psammologists work closely with patients and healthcare providers to develop effective treatment plans for psoriasis management.
