Polymorphous Low-Grade Adenocarcinoma


This rare tumor occurs predominantly in an intraoral location, with the palate the most common site. It is a tumor that may mimic many benign and malignant salivary gland tumors and for many years, was probably misdiagnosed as tumors such as adenoid cystic carcinoma and mixed tumors.

rx Surgery often followed by radiation

Rare

distant metastases. It is the first case with multiple pleural, as well as pulmonary parenchymal, metastases and metastases in cervical and paraoesophageal lymph nodes. In most cases, PLGAs are salivary gland tumours with limited potential to metastasis and a good prognosis after local treatment. However, the recently reported cases reveal that the tumour can give rise to widely spread metastases.




so the answer is

A) This is a benign pleomorphic adenoma of parotid gland.

Correct Answer Answer

This is case of Adenoid cystic carcinoma of parotid gland.
Source: BRS Pathology, table 15-1.
Figure: http://en.wikipedia.org/wiki/File:Ad...termed_mag.jpg

Adenoid cystic carcinoma of parotid:
- Most characteristic appearance consists of cribriform pattern with masses of small, dark-staining cells around cystic spaces.
- This tumor tends to infiltrate perineural spaces and cause pain;
- Slow-growing malignancy with late metastasis
-
Primary treatment for this cancer, regardless of body site, is surgical removal with clean margins
