 Hello everyone, welcome back to a new session on dentistry and more To this topic is pleomorphic adenoma From the name itself we'll get an idea about this tumor that is pleomorphic and adenoma adenoma We have seen adenoma toad or endogenic tumor something related to gland that is adenoma So what is pleo and what is morphic pleo is various Morphic is shapes. So it is a gland tumor which has various shapes elements and It is also known as mixed tumor because it consists of both epithelial and mesenchymal elements of Celebrity gland So let's get into the details of pleomorphic adenoma Pleomorphic adenoma is a salivary gland tumor and it is a most common tumor of salivary gland that It comprises of 60% of the total tumor. The second most one is What in steamer and it is often called as mixed tumor as it consists of As I mentioned in the title epithelial and mesenchymal elements So it is most commonly affects parotid gland that is 90 percentage and the remaining 10 percentage in various salivary glands Such as submantibular sublingual and other minor salivary glands So, you know what in steamer is exclusively parotid gland, but we cannot say pleomorphic it is exclusively parotid gland it is 90 percentage so remaining are Into the other salivary glands and it affects any age group, but most common in the 4th to the 6th decade that is 40 to 60 years of age group And it is the most common salivary neoplasm of children and also we can say that it is the most common salivary neoplasm of parotid gland So we'll move on to the clinical features It appears as Painless firm and mobile masses that rarely ulcerate the overlying skin or mucosa It is always painless and firm and these mobile masses rarely ulcerate and These slow-growing masses occur in the posterior inferior aspect of the superficial lobe In parotid gland it affects the posterior and inferior aspect of the superficial lobe So we know the lobes of various lobes of parotid gland. So it affects mostly the superficial lobe and Exactly the posterior and inferior aspect and if it is submantibular gland it is well defined and It's a palpable mass because submantibular gland or the location and the parotid gland location. We know it is on the Parotid gland is on the middle side of the ramus of mandible and submantibular gland It is at the lower part of the mandible So if it is in the submantibular gland that will be well-defined palpable mass And parotid gland it affects on the posterior inferior aspect of superficial lobe And this pleomorphic adenoma is very difficult to distinguish from malignant neoplasm and Inturated lymph nodes from the clinical appearance We need to go for other Investigation procedure to rule out the malignant neoplasm or an Inturated lymph nodes because it appears as a painless mass in that area So we always get confused from the clinical picture But further investigation will rule out the other possibilities. It also seen on pallet Upper lip and buckle mucosa so pallet upper lip buckle mucosa is the order of frequency and Size depends upon the gland it is affecting so size changes according to the gland where it is located So if it is in submantibular gland it takes up the shape of submantibular gland if it is parotid it takes up Parotid shape so similarly the size changes according to the gland where it is located and It will be of several centimeters in parotid gland and it will keep on increasing the size and it will become a huge mass If it is not treated In an untreated case it will be a huge mass So what is the pathology so pathology is like firm smooth mass within a pseudo capsule So there will be a pseudo capsule in this covering the mass The histological part is important. That is the epithelial cells Make up a trabecular pattern that is combined within a stroma. So these Cells can be Controid mixoid Osteoid or fibroid it can be anything so it can have various shapes So different elements May have various shapes. That is why it has got the pleomorphic or mixed tumor the name got from this That is it can have various shapes that the epithelial cells in the trabecular pattern Can have various shapes that is controid mixoid Osteoid or fibroid shape. Hence it got the pleomorphic or the mixed tumor And presence of microscopic projections of tumor can be seen outside of the capsule So treatment part it is most commonly the surgical removal with adequate margins and wide resections to To avoid the recurrence. So we keep always a wide resection and superficial Parotidctomy is sufficient if it is involving the parotid gland and If the tumor is in the tail, so we'll go for a wide margin resection of normal tissue Sparing the remainder of the superficial lobe So the tail part is if affected we can spare the Superficial lobe and go for a wide margin with a little normal tissue sparing And if it is affecting Antibular gland we should remove the entire gland It's not same as a parotid. Submantibular gland should be entirely removed So that is a treatment part commonly surgical excision will be done. So the name itself gives a clue about this Tumor that is pleomorphic adenoma. So Most of the tumor itself gives lot of clues from the title itself. So always Study the title how the title is came how the particular tumor got that name Then you can easily connect the other factors and write the detail description So that's all about pleomorphic adenoma. It is a most common tumor of Salary gland and most common salivary neoplasm of children and most commonly seen in parotid gland and How would the name got by the various elements that is controid, myxoid or astute or fibrode elements So I'll come up with a new Topic in the intestine or in oral pathology. Thank you
