Mark D. Ewalt, MD
Pathologist
My Role at MSKWe post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.
About Me
- Program Director, Molecular Genetic Pathology Fellowship
I am a pathologist who specializes in molecular genetic pathology and hematopathology. I also have an interest in developing new genetic tests for leukemia and lymphoma.

My molecular pathology work involves looking at mutations in samples from patients with cancer to diagnose, monitor, and help guide their therapies. This information also helps ensure each patient’s treatment plan is personalized to their unique cancer. As part of the Hematopathology Service, I integrate clinical and genetic information with microscopic and flow cytometry evaluation of patient tissues to diagnose blood cancers such as leukemia and lymphoma.
My research is focused on identifying the genetic changes that drive leukemia and lymphoma to uncover prognostic and therapeutic markers. This work dovetails with my clinical test development role in the Diagnostic Molecular Pathology Service.
A pathologist is a doctor who uses a microscope to make a diagnosis from cell and tissue samples. They analyze the samples to learn the cause and effects of a health condition.

Disclosures
Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.
MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.
