    Nagi K. Saied, M.D. Diplomate, American Board of Dermatology

    “My budding interest in dermatology started as I would look at the 6000-year-old mummies at the Cairo museum in Cairo. I was impressed that cultures throughout antiquity valued the skin not only as a superfluous cover but as an organ of significant political, ethnic, and even spiritual significance. Cultural taboos and stigmas were ubiquitous in viewing skin blemishes even the everyday semantics was quick to bless or curse depending on the skin pigment. The medieval undertones of leprosy and any banal skin color changes were indistinguishable”
