Abstract
A case of sialodochitis fibrinosa of the submandibular glands is reported. A 40-year-old woman consulted us with a complaint of recurrent swelling of bilateral submandibular glands for 5 years. Bilateral submandibular glands were diffusely swollen and elastic-firm. Orifices of ducts were also diffusely swollen. Salivary flow from bilateral submandibular glands was not decreased. Sialography revealed main duct dilation, and no sialolith was found. Salivary gland scintigraphy showed a slight decrease of submandibular gland function. After jelly-like material was excreted, the swelling of the submandibular glands disappeared. Hematological examination showed high levels of eosinophils and serum IgE. Allergy tests showed positive reaction for some antigens. Histologic examination of this material showed infiltration of eosinophils and remnants of epithelium. These findings are compatible with sialodochitis fibrinosa. For treatment, bromhexine chloride was administered, and the symptoms were remarkably relieved.
