Original Diagnosis


Full processing of skin tissue is
available on site.

Our dermatopathologists render a definitive diagnosis for cases ranging from typical to complex. We offer full processing of tissue within Johns Hopkins through the Department of Pathology.

Trained staff receive 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 dermatopathologists.

A dermatopathologist will read and interpret the slides, and a report is generated electronically. Once the dermatopathologist has finalized the diagnosis report, an automatic fax of the report is sent to the referring physician's fax with results.
