Pleomorphic adenoma has been reported in the eyebrow, upper eyelid, lateral and medial lower eyelid, lacrimal sac, and even intraocularly (Obi 2013). Recurrent benign pleomorphic adenoma can be multifocal and multinodular and can present multiple times after incomplete primary resection before developing malignant transformation (McNab 2011) Epidemiology. Pleomorphic adenomas account for 70-80% of benign salivary gland tumors and are especially common in the parotid gland (see below) 1,6.. Patients are typically middle-aged and the incidence is slightly higher in females than males (2:1) 1,13.. The oncogenic simian virus (SV40) may play a role in onset or progression and prior head and neck irradiation is a risk factor for the. Pleomorphic adenoma is the most common type of salivary gland tumour. Pleomorphic adenomas can arise in a variety of body sites including the skin and lungs although the vast majority arise in a type of salivary gland called the parotid gland. Pleomorphic adenomas are slow-growing tumours although they can reach a large size without treatment Pleomorphic adenoma is a benign tumor in the salivary gland. It is a firm and painless mass. Around 70-80 percent of pleomorphic adenoma occur in the superficial lobe of the parotid gland, although the lesion may occur in any area of the parotid gland. The primary cause of pleomorphic adenoma is a blockage in the salivary duct, which inhibits. In about half of cases, the size of the residual benign element is less than 1 cm. 99 Often, residual pleomorphic adenoma is extensively hyalinized, so a hyalinized nodule warrants further evaluation for carcinoma. 23,99 Infiltrative growth facilitates the distinction between benign and malignant elements
Pleomorphic adenoma is, by far, the most common benign salivary gland tumor Accounting for as many as 80% of all such tumors. Although pleomorphic adenomas most commonly occur in the parotid gland, it may also be encountered in the submandibular, lingual, and minor salivary glands . 2018 Sep;84:106-107. doi: 10.1016/j.oraloncology.2018.07.003 Pleomorphic adenomas are usually well-demarcated round tumors, most of which are encapsulated. These masses rarely exceed 6 centimeters (just under 2.5 inches) in diameter. Sometimes the capsule of the adenoma is not completely formed and this allows protrusions from the mass to extend into the surrounding parotid tissue
Pleomorphic adenoma is a painless swelling which gradually increases in size if left untreated. It has a female predilection and occ excision bears a risk of injury to the facial nerve as it enters the substance of the parotid gland and divides into its Key adenoma constitutes up to two third pleomorphic adenoma is the most commo Most SGTs are Pleomorphic Adenomas Benign parotid tumors are found in 65-75% of patients 53-77% of all parotid tumors are Pleomorphic Adenomas (PAs)6 7-14% are Warthin's <10% Oncocytoma, cystadenoma, & other Treatment for Pleomorphic Adenoma. How pleomorphic adenomas are treated depends on the size, where it is located, and at which stage the tumor is. Another big consideration is if the benign tumor has become malignant. Some choose to leave them untreated but if not treated some of the pleomorphic adenoma can experience malignant changes because. Background. Parapharyngeal space is one of potential facial planes for neoplasms and infections and represents less than 1% of all head and neck tumours. Occurrence of the pleomorphic adenoma in the parapharyngeal space is a rarity. Case Presentation. Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported Malignant changes in pleomorphic adenoma have been associated with a long duration, tumor recurrence, radiation therapy, an advanced age, and tumor size. Because the incidence of malignancy is correlated with the duration of pleomorphic adenoma, the risk of developing malignancy is only about 1.5% for a duration of <5 years but increases to 9.5.
This case report describes a 55 year-old gentleman who had been living with an extremely large (1.2 kg) pleomorphic adenoma for 24 years—despite its significant size, weight and appearance.

We present a case of a 62-year-old male patient with pleomorphic adenoma and painless solid mass in his right eye. Computerized tomography demonstrated a mass with a diameter of 2.5 cm located in the right lacrimal gland. The mass was removed completely by combined orbitofrontal craniotomy through a transcranial approach Pleomorphic Adenoma (RPA) treated with surgery alone or surgery plus adjuvant RT at the McGill University Healthcare center (MUHC) between 2000 et 2010. Introduction Pleomorphic adenoma is the most frequent benign salivary gland tumor of the parotid gland. Although the recurrence rate after parotidectomy is low, significa Pleomorphic adenomas vary in size usually being 2-6 cm in diameter in the major salivary glands, whilst they are much smaller in the minor salivary glands. There are also some huge ones on record and referred to as giant pleomorphic adenoma
Pleomorphic adenoma of minor salivary gland is most common in palate (10%), followed by lip (4%).Approximately 34.7-67.1% of salivary gland tumors arising from an intraoral site are benign. The smaller the salivary gland that is affected, the more likely i Carcinoma ex pleomorphic adenoma (CXPA) is an uncommon malignant tumor with highly aggressive biological behavior. Our goal was to investigate the prognosis of CXPA in the major salivary glands and factors influencing it. We retrospectively reviewed 51 patients diagnosed with CXPA of the major salivary glands between 1999 and 2006, comprising 36 males and 15 females, aged from 23 to 86 years The patient received chemo-radiation but tumor increased in size, and then tumor was found to be a benign pleomorphic adenoma. Possibly, myoepithelial or epithelial atypia with keratin debris in pleomorphic adenoma (Fig 4 ) led to cytological diagnosis of carcinoma Pleomorphic adenoma of the breast. A 'pleomorphic' adenoma is a very rare sub-type of breast adenoma, which is a proliferative neoplasm in some combination of glandular, fibrous, and fat tissues.These generally benign tumors are usually asymptomatic and unless they have grown into a palpable lump, they would generally only be detected through imaging studies done for some other reason The primary tumor size ranged from 1.2 to 11.6 cm (median 3.5 cm). Tumor size was unknown for 3 patients. All cases by definition contained pleomorphic tumor cells with more than 6-fold variation in nuclear size in more than 50% of the tumor cells evaluated . Multinucleated tumor giant cells were present in all cases

It was the size of a golf ball on my shoulder and was high grade Pleomorphic Adenoma. a benign tumor of the salivary gland containing varying proportions of epithelial and mesenchymal elements. Also called mixed salivary gland tumor. CT scans and magnetic resonance imaging are utilized to determine the size of the mass and its location. A biopsy is done to confirm whether the tumor is benign or malignant The operation is supposed to be simple 2-3hours operation depending on the location of the tumour. In my case the procedure was a little tedious and took 6hrs 15mins. Post the operation the superficial part of the parotid gland was removed as seen in the figure above. As a result of the operation there is a little bit of bleeding in the parotid. All eight pleomorphic adenomas had distinct mar-gins and ranged in diameter from 0.5 to 3 cm (mean, 1.3 6 0.46 cm short axis 3 2 6 0.72 cm long axis). For seven of the eight pleomorphic adenomas, the degree of lesion enhancement increased with time, becoming more uniform and homogeneous, with progression from the tumor margins (Fig 2)

Major salivary gland cancer (SGC) and salivary gland pleomorphic adenoma (SGPA) together constitute almost three quarters of all salivary gland tumors, and have a yearly incidence of respectively 0.7 and 4.9/100,000 person‐years in the Netherlands (European Standardized Rate). 1, 2 Benign salivary gland tumors occur 6-7 times more frequently than malignant tumors and the. FNA of pleomorphic adenoma is fairly accurate if you have a small tumor and enough material to look at under microscope. Even though the diagnosis of pleomorphic adenoma is benign but there is a small (5-10%) chance that it might be associated with carcinoma/malignant cancer or it might transform into one. Also it may recur
Pleomorphic adenomas account for the majority of parotid masses, typically arising in the tail of the gland and enlarging slowly over time. The vast majority are 2 to 6 cm in size when resected. We report resection of the largest benign mixed tumor recorded in the modern English language literature The average size of Warthin's tumor at diagnosis is about 2.5 centimeter. The great majority of these tumors are located in the lower pole of the parotid gland. In about 12% of cases, there is bilateral tumor development, which is commonly synchronous. They may occur simultaneously with pleomorphic adenomas, various types of carcinoma and. Basal cell adenoma is a rare benign epithelial tumor of the salivary gland, accounting for 1-2% of all salivary gland epithelial tumors .More than 80% of basal cell adenomas arise in the major salivary glands, mostly the parotid gland .Clinically, they usually present as a painless palpable mass, indistinguishable from other salivary gland tumors, including pleomorphic adenoma, the most.
