Endoscopic signs help characterize endoscopic lesions. The endoscopic appearance of esophageal ectopic sebaceous glands (ESGs/Fordyce lesions) has been described in several case reports [1, 2], but none have described its endoscopic appearance as potentially characteristic or mimicking a type of cutaneous sebaceous glands. This report describes that its endoscopic appearance and histopathology mimics that of cutaneous closed comedones (colloquially, whitehead pimples), explains the pathophysiology, and reports a novel potentially diagnostic endoscopic sign.

A 78-year-old-female presented with postprandial-abdominal-pain. Physical examination and routine laboratory tests were within-normal-limits. Esophagogastroduodenoscopy (EGD) revealed numerous, 3–4-mm-wide, discrete, pinkish, mucosal plaques with prominent, white, central punctae (Fig.  1a, b) in clusters in middle and distal esophagus with normal intervening mucosa (and unremarkable stomach and duodenum). Histopathologic analysis...
