They incarcerate or entomb minor mucoserous
glands and invade into the adjacent soft tissues.
The stroma is variable, ranging from dense and fibrous to loose and myxoid, but usually without minor mucoserous
Though mucociliary dysfunction leading to increased secretions may be associated with situs inversus, there were no signs and symptoms suggestive of increased mucoserous
secretions (history of repeated sinusitis, bronchiectasis) in our case.
The 2 challenged calves showed only mild clinical signs consisting of mucoserous
nasal discharge, hyperthermia, and moderate leukopenia.
14,15) ACC-HGT typically occurs in the sixth decade and most commonly involves the sinonasal mucoserous
glands, submandibular glands, and palate, with only one case in the parotid reported to date.
The tumor surrounds and entombs the associated minor mucoserous
salivary glands and invades the surrounding soft tissues, exhibiting a characteristic "targetoid appearance" around nerves (figure 1).
Classically, it involves the mucoserous
glands of the hard palate.
In general, excision of the lesion to include adjacent minor mucoserous
glands will reduce the chance of recurrence.
11] On the other hand, the identification of melanocytes in the submucosal compartment and mucoserous
glands of the larynx led to the assumption that primary malignant melanoma could arise in the larynx not only from melanocytes present in the surface epithelium, but also from those present in the submucosa.
Adenocarcinomas of the sinonasal tract can originate in the respiratory epithelium or the underlying mucoserous
MEC can also involve a variety of other sites that have minor mucoserous
Sinonasal tract adenomatous tumors have been presumed to arise from submucosal mucoserous
