Abstract : A number of matching histological forms were seen in polymorphous low grade adenocarcinoma (PLGA) and adenoid cystic carcinoma (ACC) including three patterns which are solid , tubular and cribriform. The bisecting features of clinicopathology of PLGA and ACC may end in a challenging diagnostic. ACC has a briform adenocarcinoma of the tongue and signet ring adenocarcinoma of minor salivary gland. Known 7% of polymorphous low-grade adenocarcinomas and 12% of monomorphic aden-omas.16 In another study, CD43 expression or molecular genetic studies,31–33 a recent study using

Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast, lacrimal gland, lung, brain, bartholin gland, trachea, and the paranasal sinuses.. It is the third-most common malignant salivary gland tumor overall (after mucoepidermoid The microscopic patterns of adenocarcinoma varied from trabecular, tubular, solid, papillary or mucus-secreting varieties without epidermoid traits to glandular carcinomas with partial sebaceous gland differentiation. In the present study, the term polymorphous …

Several reports have suggested that c-kit is expressed in adenoid cystic carcinoma (ACC). It is reportedly absent in polymorphous low-grade adenocarcinoma (PLGA).1, 8, 9 On the basis of these findings, it has been suggested that c-kit expression may be a suitable immunohistochemical marker to aid in distinguishing between these 2 neoplasms. recent follow up the patient has no signs of residual disease. No adjuvant therapy was offered to our patient due to the low histological grade and clear resection margins; Vol. 61, No. 9, September 2011 946 Figure-1: Axial (A) and Coronal (B) CT scan with contrast showing a …

Polymorphous low-grade adenocarcinoma (PLGA) is a rare malignancy which could usually be seen in minor salivary glands. In this case diagnosis, management and treatment of PLGA of hard plate is presented with recent literature review. Introduction Polymorphous low grade adenocarcinoma (PLGA) is a malignant Detailed studies should be Polymorphous Adenocarcinoma (PAC) ABSTRACT: Polymorphous adenocarcinoma (PAC) is almost entirely related to minor salivary glands. It is mostly found in the palatal region but on rare it was also observed in other intraoral areas. In recent studies it is observe that there is a potential for histological transformation of the lesion from low to

phous low grade adenocarcinoma is almost exclusively a tumour of minor salivary glands, with over 60% arising in the palate. The remainder usually occur in the buccal mucosa or upper lip. Polymorphous low grade adenocarcinoma was first described in 1983, but prior to … Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast, lacrimal gland, lung, brain, bartholin gland, trachea, and the paranasal sinuses.. It is the third-most common malignant salivary gland tumor overall (after mucoepidermoid

carcinoma and polymorphous low-grade adenocarcinoma respectively. Adenosquamous cell carcinoma is a malignant tumour with the histological features of both adeno-carcinoma and squamous cell carcinoma, but it is not listed as a salivary gland entity in the recent classification.15 Therefore, except polymorphous low-grade adeno- Other studies have reported a relative frequency of acinic cell carcinoma from 0% to 19% of malignant salivary gland neoplasms.
