Pellagra‐like erythema on sun‐exposed skin of patients with anorexia nervosa

The anterior neck was suggestive of Casal’s necklace, characteristic of this disease, and azathioprine was the cause of pellagra, taking into account that it was the only medication known to interfere in the niacin pathway.
Pellagra: a still existing disease
TLDR
Pellagra is no longer the medico-social problem it was in the past but in countries with a low nutritional level it continues to a considerable degree in endemic form and in areas of the so-called 'civilized world' where nutritional problems do not really exist, occasional cases are found.

TLDR
The conversion from Az to a less myelosuppressive drug, such as FK506, should be considered in renal transplant recipients with severe myelOSuppression caused by long‐term Az treatment, as well as in patients with severe megaloblastic anemia with pancytopenia.
Pellagra, azathioprine and inflammatory bowel disease
TLDR
