Certain dermal appendage tumors have a striking histologic and clinical homology with some tumors arising from the salivary duct system. The dermal eccrine cylindroma is an exemplar. Arising from the eccrine ducts, this neoplasm is only occasionally found outside the head and neck, has a recurrence rate of over 40%, and in its malignant form is a high-grade carcinoma. Its counterpart in salivary glands the dermal analogue tumor, manifests a histologic similarity, if not identity, also has a relatively high recurrence rate, and can also undergo malignant change.

Adenocarcinomas of salivary glands are encountered less frequently than adenoid cystic or mucoepidermoid carcinomas. They fall into two well-defined clinicopathologic groups: 1) those arising from intercalated ducts and 2) those from the excretory and interlobular ducts. The former, designated terminal duct adenocarcinomas, are low-grade malignancies found preponderantly in the oral cavity, especially the palate. The latter, designated salivary duct carcinomas, are high-grade neoplasms and arise almost exclusively in major salivary glands, especially the parotid gland.

SummaryTaastrup virus (TV) is a novel virus belonging to Mononegavirales and with filovirus-like morphology. In adult Psammotettix alienus infected with TV, the highest concentration of virus particles was found in salivary glands, consisting of a principal gland (type I-VI-cells) and an accessory gland. Examination of thin sections revealed enveloped particles, about 1300 nm long and 62 nm in diameter, located singly or in paracrystalline arrays in canaliculi of type III- and IV-cells. In gland cells with TV particles in canaliculi, granular masses up to 15 micrometer in diameter are present in the cytoplasm. These masses are believed to be viroplasms, the sites for viral replication. TV particles were observed at the connection between a canaliculus and the salivary duct system.

Direct Damage

AbstractBackground:Sialendoscopy can be followed by swelling and infection of the salivary gland. A possible pathomechanism is damage of the deeper salivary duct system by intraductal pressure generated by the irrigation fluid.Method:After measuring the physiological intraductal pressures which arise during sialendoscopy, these pressures were simulated in freshly excised salivary glands and the tissue was analysed histologically.Results:Normal intraductal filling pressure during sialendoscopy is 100–250 daPa, and pressure peaks can be up to 2000 daPa during flushing. A filling pressure of more than 400 daPa results in dilatation of the salivary ducts and acinar area. No direct damage to any duct structures could be observed histologically.Conclusion:Irrigation fluid should be administered intermittently rather than continuously during sialendoscopy. The intraductal filling pressure should not exceed 400 daPa to minimise the trauma to the salivary duct system and reduce the risk of developing oedema and inflammation.

Carcinoma Of The Larynx

Salivary duct carcinomas are primarily high-grade, aggressive malignancies that affect men in the fifth and sixth decades of life. These tumors are usually found in the major salivary glands; rarely do they originate in the minor salivary glands. The distinctive feature of these neoplasms is their remarkable histologic resemblance to infiltrating ductal carcinomas of the mammary gland; both types of tumor feature epithelial and myoepithelial cells arrayed in solid, papillary, and cribriform patterns. To the best of our knowledge, only one case of a primary salivary duct carcinoma of the larynx has been previously reported. In this article, we describe a new case, and we review the literature on salivary duct carcinomas.

There is currently no consensus on the etiopathogenetic nature of endometriosis. The causes of aggressive, progressive, infiltrative growth of endometrioid tissue also remain unclear. An important problem remains the high recurrence rate of endometriosis, despite the availability of modern drug and surgical methods of treatment. The study of the central signaling pathways and the search for new key molecules is of paramount importance for a better understanding of the pathogenesis of the disease, and is also an important step in the development of new strategies for the diagnosis, prevention and treatment of endometriosis.
