Human epidermal receptor 2-amplified salivary duct
carcinoma: regression with dual human epidermal receptor 2 inhibition and anti-vascular endothelial growth factor combination treatment.
She was diagnosed, at another institution, with salivary duct
carcinoma with multifocal perineural and intraneural invasion and underwent partial parotidectomy.
Drug delivery through the salivary duct
offers many possibilities.
These included frictional keratosis (fig 1), hyperplastic candidosis, angular cheilitis (fig 2), Buccal mucosal pigmentation, petechial haemorhages (fig 3), mucosal ulcers (fig 4) and inflamed sublingual salivary duct
A ruptured salivary duct
that was feeding into the area was also present( Fig.
A blocked gland is more common around the teeth and can happen when small stones - made from calcium - build up in the salivary duct
. This may trigger a painful swelling of the affected gland at mealtimes when saliva is normally produced.
Oral mucosa and gingiva was normal and salivary duct
openings were patent with good oral hygiene.
Low-grade salivary duct
carcinoma (LGSDC), (20) also known as low-grade cribriform cystadenocarcinoma, displays intraductal proliferations of low-grade ductal cells forming filigreed and anastomosing micropapillae along with loose cribriform and occasional solid patterns analogous to atypical ductal hyperplasia and low-grade ductal carcinoma in situ of the breast (Figure 3).
Focal seromucinous acini of the salivary gland type were detected near the clefts, and no salivary duct
Painless swelling of neck and oral cavity is the most common clinical sign associated with salivary gland abnormalities in dogs or cats, resulting from abnormal saliva accumulation secondary to a blocked or lacerated salivary duct
They included pleomorphic adenoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, Warthin tumour, salivary duct
carcinoma, basal cell adenocarcinoma, myoepithelioma, adenocarcinoma NOS, Polymorphous low-grade adenocarcinoma and a case of undifferentiated carcinoma.
She recovered well, with no sialocele or salivary duct
obstruction or sialadenitis.
