Additional Symptoms
Skin lesions can form anywhere, but they're usually present on the lower legs, feet, arms, hands, face or neck. Pellagra was once known as Casal's necklace or collar due to lesions around the neck.1Piqué-Duran, E, et al. ‘Pellagra: a Clinical, Histopathological, and Epidemiological Study of 7 Cases.’ Actas Dermo-Sifiliograficas, U.S. National Library of Medicine, 2012, www.ncbi.nlm.nih.gov/pubmed/21737056
Pressure points are also prone to developing lesions, and a pellagrous glove forms when lesions spread over the hands and fingers. Other symptoms include redness, inflammation and cracking in the corners of the mouth and eyelids.
