Sorry if my pictures gross you out, but I wanted to share this amazing case with you. This man has a disease called Pellagra. Pellagra is caused by a deficiency in Vitamin B3 (Niacin). Patients with pellagra usually have a diet that is rich in unprocessed corn. It can also occur in alcoholics due to malnutrition. The treatment is very simple, you just have to give the patients a vitamin. Ofcourse we ran out of oral Vitamin B Complex today in the hospital so my patient has not been recieving his mediations.

If Pellagra is left untreated it will result in progressive dementia and ultimately death. Pellagra is a very preventable and treatable disease.


  1. I am stunned at how meds run out so quickly and randomly so you don't even know what's out.

    You really are a great teacher. It's interesting to read what you write and teach us back in the States, but you have always been a great teacher. Those interns and students down there are lucky to have Dr. Mack!

  2. Dear Doctor,

    I am Dr. Sudha Shivaraj, a pathologist writing to you from India. I have written a book on General Pathology named 'Essentials of General Pathology' which has been approved by Wiley Blackwell and will be published in May 2013.

    I came across your image of pellagra in google images. I request you to kindly grant me permission to use the clinical photograph of Pellagra in my book. The image will be attributed as per your instructions.

    Thank You,
    Warm Regards
