Figure shows a rash around a neck.
This rash is known as Casal’s necklace because it forms a ring around the neck; it is seen in advanced cases of niacin deficiency.
The early symptoms of pellagra include loss of appetite, generalized weakness and irritability, abdominal pain, and vomiting.
Bright red glossitis then ensues, followed by a characteristic skin rash that is pigmented and scaling, particularly in skin areas exposed to sunlight.
Vaginitis and esophagitis also may occur. Diarrhea (in part due to proctitis and in part due to malabsorption), depression, seizures, and dementia are also part of the pellagra syndrome—the four Ds:dermatitis, diarrhea, and dementia leading to death.
