Prominin-1 (CD133) is physiologically expressed at the apical membranes of secretory (serous and mucous) and duct cells of major salivary glands. We investigated its expression in various human salivary gland lesions using two distinct anti-prominin-1 monoclonal antibodies (80B258 and AC133) applied on paraffin-embedded sections and characterized its occurrence in saliva. The 80B258 epitope was...
This review summarizes the new findings on salivary gland pathology under the following categories: immunohistochemistry; molecular genetics; newly recognized tumour types; known tumour entities with new findings; and progression of salivary gland tumours. In the application of immunohistochemistry, CD117 can aid in highlighting the luminal cell component of various salivary gland tumours, wher...
PURPOSE Previous evaluation of HER2 overexpression in salivary gland cancers indicated an incidence varying between 7 and 56%, with no clear difference among three histologically different subtypes. As part of a Phase II trial of trastuzumab for treatment of incurable salivary gland cancer, we screened 137 tumors for HER2 expression. EXPERIMENTAL DESIGN Unstained sections of paraffin-embedded...
BACKGROUND The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. MATERIALS AND METHODS Fifty thre...
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...
Salivary duct carcinoma (SDC) is a rare and highly aggressive cancer with a worse prognosis that has been demonstrated to exhibit invasive growth with early regional and distant metastasis. Breast metastasis of salivary duct carcinoma rarely occurs. Here, we reported a case of submandibular gland SDC metastasis to breast in a 64-year-old female patient who underwent a complete removal of a righ...
