Dermatopathology Laboratory

Laboratory Services

In 2011, OHSU Dermatology built a state-of-the-art histopathology laboratory, designed from the ground up specifically for dermatopathology services. Our laboratory enhances the expert diagnostic services that we have provided since 1979 by giving us the ability to produce a customized lab product specific to skin diagnoses. In addition, having an in-house laboratory has allowed us to decrease the time for results - now on average 18-24 hours for routine cases.
Dermatopathology Laboratory

Our laboratory technicians have worked with our dermatopathologists to utilize customized methods and procedures to meet the specific requirements requested by our board certified physicians so we can ensure the highest quality product is produced every time.

Whether you choose to read and diagnose your tissue samples, or have our dermatopathologists read and report their diagnosis, our slide preparation quality is a priority. In addition to Hemotoxylin and Eosin (H & E) staining, we also offer a broad range of special stains and immunohistochemistry. Click here to view our full dermatopathology testing menu.

We offer routine and stat pick-up service within the entire Portland Metro and selected surrounding areas and offer complimentary FedEx service for those outside of our courier area. We also provide all of the supplies you will need for sending samples. A completed requisition form is needed and includes the referring physician’s name, phone and fax number, the patient demographics and insurance information and the date and site of the biopsy, including clinical context.
