Abstract:
Sialodochitis fibrinosa is a disease characterized by salivary duct obstruction. A 21-year-old male presented with a painful submandibular gland (SMG) swelling. Serum eosinophilia and Whartons’ duct dilatation with strong enhancement were observed on contrast CT. Core needle biopsy (CNB) for SMG parenchyma revealed lymphocytic infiltration between dilated intralobular ducts. In another case, a 39-year-old male complained of recurrent major salivary glands swelling for ten years with an itching sensation on the overlying skin of the salivary gland. Enhancement of both SMG parenchyma, dilatation of both Wharton’s ducts and elevated serum eosinophilia were observed on contrast CT study. CNB for SMG parenchyma revealed lymphocytic infiltration with many eosinophils around a markedly dilated interlobular duct. The recurrent SMG swelling in both cases were relieved by antihistamine medication, warranting suspicion that these cases might organ-specific eosinophilic disease. We dicuss these two cases with a literature review.
