42-year-old woman with steroid-induced Cushing’s syndrome and type 2 diabetes mellitus with peripheral neuropathy was referred with a presumptive diagnosis of emphysema while on chronic prednisone therapy for 4 years, inhalable steroids, and supplemental oxygen. Her neuropathy was treated with gabapentin. She complained of worsening cough, wheezing, and some retrosternal discomfort in a recumbent position. She was diagnosed with possible reflux disease on the basis of esophagogastroduodenoscopy 5 years earlier but was not treated for it. Her pulmonary function tests including methacholine challenge were negative. High-resolution computed tomography scan of the chest showed scattered areas of ground glass opacity through the lungs but no signs of emphysema. Alpha1-antitrypsin level was normal.

Chronic esophageal reflux disease was suspected, and during repeat esophagogastroduodenoscopy, mild pill esophagitis was noted, with lettering seen on the esophageal mucosa (Figures A, B). The imprint was then removed easily with saline washing. The culprit was identified as a gabapentin pill by the analysis of the letters from the esophageal wall because, literally, the writing was on the wall (Figure C). The patient improved with conservative therapy.
