Oral Pathology

We are glad to accept tissue specimens for Oral Pathology to render an original diagnosis.  Second opinion or confirming consultations are also available through our Oral Pathology service if glass slides are sent instead. 

Original Diagnosis

We offer full processing of tissue within Johns Hopkins through the Department of Pathology. 

Trained staff receive oral tissue samples in formalin bottles and immediately accession the sample and paperwork into an electronic system. Next the tissue is placed into cassettes and processed. A paraffin block is made by embedding the tissue in paraffin and then the block is cut and placed onto slides. A staining agent fixes the tissue to the slides which are then slipcovered and read by our Oral Pathologists.

Once a diagnosis is rendered based on the slides made from tissue submitted, a report is generated electronically. An automatic fax of the report is sent to the referring physician's fax with results once a final sign-off is given by the attending pathologist.

To receive requisitions and mailing supplies to submit specimens, please call 410-955-3484. We are glad to mail these supplies to referring physicians' offices and to coordinate mailing services.  You may also conveniently download requisitions for original diagnosis from our website. We ask that you complete the requisition in its entirity to enhance patient safety and speed processing.

Second Opinion or Confirming Consultations

After glass slides are received and immediately accessioned through the Department of Pathology's consultation office, along with all supporting documentation, our dermatopathologists review the slides and may either render a definitive diagnosis or recommend further immunohistochemical or molecular studies for the case to confirm the diagnosis.   

Once a diagnosis is rendered based on the slides submitted, a report is generated electronically. Once the dermatopathologist has finalized the report, an automatic fax of the report is sent to the fax number listed in the Pathology Consultation Form with results. 

Slides will be returned to their original source within 60 business days.  If slides are needed before that time, a request may be faxed to the Pathology Office at 410-614-7712.
