Pneumoparotid is defined as the presence of air within the parotid gland or duct. Pneumoparotid is an extremely rare cause of parotid gland swelling. Pneumoparotid can be induced by air insufflation from oral cavity into the intraparotid salivary ducts, in condition like nose blowing, blowing up balloons, during extubation after general anesthesia while receiving positive pressure, rapid decompression while scuba diving, chronic attempts to suppress cough, and glassblowers. It can also be self-induced, and the literature contains an increasing number of reports involving pediatric and adolescent patients who induce parotid insufflation to avoid school or gain attention. Here, we report a case of pneumoparotid caused by habitual cheek inflating and improved with conservative treatment.

The ultrastructure of submandibular gland was examined in the Korean spider shrew, Sorex caecutiens. The submandibular gland wat composed of acini and salivary ducts. A submadibular acinus was a mixed gland having serous demilune cells and mucous cells that were filled with well developed rER, mitochondria and large amount of dense secretory granules. Serous acinar granules were oval shape without distinct limiting membrane on the border and it had only coarse specks with various density. Mucous acinar granules were oval shape without distinct limiting membrane and had a variety pattern with several thin or transparent bands into the homogeneous dense matrix. Thus submandibular acinar granules of S. caecutiens belonging to subfamily Soricinae were distinct from the other mammalian species including Crocidurinae, because of the absence of limiting membrane of acinar granules and specific pattern of mucous acinar granules. Granular duct cells had large amount of small granular vesicles and several characteristic structures of granule which were revered with stratified limiting membranes and filled with coarse serous-like granule or homogeneous matrix.
