Eosinophilic Sialodochitis Identified in Duct Remnant After Submandibular Gland Resection.

Abstract

Eosinophilic sialodochitis (ES) is an increasingly recognized cause of recurrent sialadenitis but likely remains underdiagnosed as it is commonly considered to be nonspecific chronic sialadenitis. ES is likely increasing in prevalence in association with the growing number of allergic diseases and should be considered in patients presenting with multiple episodes of salivary gland pain and swelling refractory to conventional treatment. We highlight this difficulty in diagnosis with a report of ES established following Wharton duct remnant swelling after submandibular gland (SMG) resection for stone removal with photographic, histopathologic, and radiographic analysis.
