An esophagogastroduodenoscopy showed nodularity and linear ulcerations in the upper third of the esophagus 27-32 cm from the incisors (Figure 1).
Immunohistochemical stain showing (A) abundant dystrophic calcification within fibrinopurulent debris at the ulcer site (200x), (B) intact squamous mucosa with focal subepithelial calcification (200x), and (C) a detached fragment of squamous epithelium with intraepithelial calcification (400x).

However, small foci of subepithelial and intraepithelial calcification were identified, consistent with a diagnosis of esophageal mucosal calcinosis (Figure 2).
