She was diagnosed with anemia based on a hemoglobin level of 10.8 g/dL (the cutoff value for a female is 11 g/dL). (A) Physical examination revealed complete tongue atrophy, with a glossy appearance. (B) Complete resolution after 1 month of supplement therapy. (C) The therapeutic effect was still evident during follow-up at 6 months. (Source: Chen GY, Tang ZQ, Bao ZX.
