Résumé
Afatinib is an oral tyrosine kinase inhibitor (TKI) that inhibit Endothelial Growth Factor Receptor (EGFR), Human Epidermal Growth Factor Receptor 2 (HER2), and HER4. The common side effects of EGFR TKI are rash, acne, diarrhea, stomatitis, pruritus, nausea, and loss of appetite. Drug induced pneumonitis is the less common adverse effects of EGFR TKI. Afatinib, 2nd generation EGFR TKI is anticipated to overcome drug resistance from 1st generation EGFR TKI according to preclinical study, and several studies are being conducted to compare clinical efficacy between 1st and 2nd EGFR TKI. Several cases of rug induced acute fatal pneumonitis were reported after use of erlotinib or gefitinib. However, a case of acute fatal pneumonitis associated with afatinib was note reported except drug induced pneumonitis in other clinical study. Here, we present a cases of acute severe pneumonitis related with afatinib in metastatic lung adenocarcinoma with literature review.

Plummer-Vinson syndrome is characterized by dysphagia, iron deficiency anemia, and upper esophageal web. The associated symptoms can be resolved by administering iron supplements as well as by endoscopic intervention. Relapse in patients with Plummer-Vinson syndrome is very rare. We describe a case of a 42-year-old woman with Plummer-Vinson syndrome whose symptoms were successfully treated with endoscopic dilatation and iron supplementation at first admission; however, 1 year later, she revisited our hospital because of dysphagia. On second admission, investigations revealed esophageal web relapse in Plummer-Vinson syndrome. She was again successfully treated with endoscopic dilatation and iron supplementation. After first admission, her anemia was not normalized due to poor compliance and loss of follow-up. We experienced a case of esophageal web relapse due to uncorrected iron deficiency anemia in a patient with Plummer-Vinson syndrome. This experience indicates that continuous iron supplementation and long-term follow-up is important in patients with Plummer-Vinson syndrome.
