Explanation: 

Detailed explanation-1: -Pellagra is a disease that occurs when a person does not get enough niacin (one of the B complex vitamins) or tryptophan (an amino acid).

Detailed explanation-2: -A severe niacin deficiency leads to pellagra, a condition that causes a dark, sometimes scaly rash to develop on skin areas exposed to sunlight; bright redness of the tongue; and constipation/diarrhea.

Detailed explanation-3: -One form of niacin deficiency results from a deficiency of niacin and tryptophan (an amino acid). This form causes a disorder called pellagra, which affects the skin, digestive tract, and brain. Pellagra develops only if the diet is deficient in niacin and tryptophan because the body can convert tryptophan to niacin.

Detailed explanation-4: -Vitamin B6 deficiency causes peripheral neuropathy and a pellagra-like syndrome, with seborrheic dermatitis, glossitis, and cheilosis, and, in adults, can cause confusion, electroencephalogram abnormalities, and seizures.
