Glossitis linear or patchy red lesions. Vitamin B1 deficiency (thiamin deficiency) can cause glossitis. Vitamin B2 deficiency (ariboflavinosis) can cause glossitis, along with angular cheilitis, cheilosis, peripheral neuropathy and other signs and symptoms. The glossitis in vitamin B2 deficiency is described as magenta. Vitamin B3 deficiency (pellagra) can cause glossitis. Vitamin B6 deficiency (pyridoxine deficiency) can cause glossitis, along with angular cheilitis, cheilosis, peripheral neuropathy and seborrheic dermatitis. Folate deficiency (vitamin B9 deficiency) can cause glossitis, along with macrocytic anemia, thrombocytopenia, leukopenia, diarrhea, fatigue and possibly neurological signs. Apart from pernicious anemia discussed above, any other cause of vitamin B12 deficiency
