ABSTRACT
Pellagra is caused by deficiency of niacin or its amino acid precursor
tryptophan. Clinical features are characterized by dermatitis,
diarrhea and dementia. Dermatitis is observed only in 33%
of patients. We report a 86-year-old female who presented
a disseminated, bilateral and symmetrical dermatosis predominantly
in sun-exposed areas, characterized by well-defined, hyperpigmented
plaques and distal desquamation with gloves-like
aspect. Pellagra was diagnosed and treatment with supplement
and oral niacin was started, with significant improvement.
