Pathology Service


Biopsy Service
Texas A&M University Baylor College of Dentistry

The Department of Pathology provides an oral histopathology service for clinicians. The biopsy service in its present form began in 1980 and currently approximately 8000 cases are processed annually. Most of these were from clinicians in North Texas but many came from other parts of the state or other states.

Most specimens are received by mail. For urgent specimens, we offer free overnight express service. The diagnoses are mailed within 24 hours of the specimen being received and, if urgent, the clinician is called or faxed with the diagnosis by the pathologist on duty.

The pathologists are:

  • Yi-Shing Lisa Cheng, DDS, MS, PhD
  • Harvey Kessler, DDS, MS
  • John M. Wright, DDS, MS
  • Aparna Naidu, DDS, MS


We can bill the clinician or the patient. In addition, services can be billed directly to medical or dental insurers, medicare or Medicaid.

The department supplies mailing containers which include a request form with specimen bottle and fixative. If you would like us to send you some containers (free of charge), please contact:
