The salivary gland system consists of a network of major and minor secretory glands and ducts, that keep the oral cavity and upper aerodigestive tract moist and lubrificated; the oral salivary glands dissolve also water-soluble compounds and begin the digestion 1. They account for 6-8% of all tumours of the head and neck area, and the majority of them are benign and occur in the parotid gland. ...
Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...
The expression of sex hormone receptors in some tumors suggests a role for these receptors in tumor pathogenesis and therapy. Previous studies of the expression of estrogen and progesterone receptors in salivary gland tumors have reported conflicting results. We evaluated the immunohistochemical expression of androgen, estrogen, and progesterone receptors (AR, ER, and PR) in a series of 78 form...
Sialolithiasis is the most common disease of salivary glands. Commonly, sialoliths measure from 5 to 10 mm in size and stones over 10 mm can be reported as sialoliths of unusual size. Giant sialoliths measuring more than 35 mm are extremely rare, with only around 17 cases published in the literature. We report an asymptomatic case of a sialolith in the submandibular duct measuring 62 × 20 mm an...
BACKGROUND Salivary gland dysfunction with xerostomia is a major clinical problem without a causal therapy in most cases. The development of an animal model for scintigraphic assessment of salivary gland function has great clinical relevance for the investigation of promising new diagnostic and therapeutic strategies for chronic salivary gland diseases. This study reports the first experiences ...
Sjögren’s syndrome (SS) is an autoimmune disease in which exocrine glands including the salivary gland are targeted and destroyed by the immune system (Voulgarelis and Tzioufas, 2010). SS and the side-effects of γ-radiation therapies for head and neck cancers cause salivary gland dysfunction, in particular hyposalivation (Atkinson et al., 2005; Fox, 1998; O'Sullivan and Higginson, 2010). Among ...
Salivary gland tumors are uncommon within children and when they do arise, they mainly affect the major salivary glands. Minor salivary gland tumors are rare in children, which are responsible for less than 10% of all the cases. Pleomorphic adenoma is the most common tumor of the sa...
