About me

Dr. Alexander Witkowski is a medical dermatologist specializing in the early detection of skin cancers (particularly melanoma), eczema, seborrheic dermatitis and acne.

Dr. Witkowski completed his medical training and residency in Europe as well as his Ph.D. in Modena (Italy), focused on implementing virtual biopsies with reflectance confocal microscopy and its application to diagnosing melanoma subtypes at the patient bedside. 

He is an international instructor in this topic and successfully introduced this specialized medical technology in Poland. He now joins OHSU as the co-director of the Skin Cancer Imaging Center to help spread this technology for the benefit of Oregonians and beyond.

Your insurance company will also be able to inform you of any copayments, co–insurance, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with OHSU providers, your out of pocket liability may be higher.
