Fulltext PDFPleomorphic Adenoma (PA) can be defined as a benign mixed tumor composed of epithelial and myoepithelial cells arranged with wide cytomorphologic and architectural diversity and morphological patterns, demarcated from surrounding tissues by fibrous capsule. Parotid gland is most commonly affected. The tumor is surrounded by pseudo capsule which is often dehiscent and there are fingerlike projections known as pseudopodia into the surrounding parotid tissue. This is why simple enucleation of the tumor led to a higher rate of recurrence. Occurrence of pseudopodia; microscopic finger like formations of tumor tissue that extend beyond the main lump of the tumor is a significant risk factor for local recurrence. Pseudopodia extending to lumen of parotid duct have been found in this case, increasing the risk of recurrence in such cases. The rate of tumor recurrence after surgery for benign salivary gland pleomorphic adenoma varies considerably in different clinical settings and seems to depend to a great extent on the surgical technique used. The importance of tumor spillage for subsequent recurrence has recently been questioned.
