What is a mucinous tumor?
Mucinous tumor is a cystic neoplasm filled with mucus material called mucin and lined with atypical epithelial cells. It can be benign mucinous cystadenoma or malignant mucinous cystadenocarcinoma. Benign mucinous tumors often have several cystic lobes lined with smooth epithelial lining. Malignant mucinous tumors often have solid areas and papals with cellular atypia and stratification, abnormality in tissue architecture and necrosis. The cells of mucinous tumors are similar to endocelling or intestinal cells. In mucin tumors with appendiceal and large intestines, benign mucinous cystadenoma has the same rough appearance as malignant mucinous cystadenocarcinoma and can only be differentiated through histopathological examination. About 15 to 25% of all ovarian neoplasms are ovarian mucinous tumors and approximately 6 to 10% ovarian mucinous tumor are malignant. Peace tumors in the pancreas are also quite common.
benign mucinous ovarian tumors commonly occurIn women aged, while in women between the age of 30 and 60, malignant mucinous ovarian tumors occur. Ovarian mucinous tumor is usually one -sided and bilateral involvement in a mucinous tumor requires further examination. About 5% of bilateral ovarian mucinous tumors are benign, while about 10 to 20% of two -sided ovarian tumors are malignant.
about two -thirds of the instances of mucinous tumor formation are in the tail or abdominal body. These are commonly seen in perimenopausal women. They are slowly growing tumors where affected individuals usually do not suffer from pain. Pancreatic mucinous cystadenoma represents 45% of pancreatic tumors and intradukal papillary mucinous adenoma is 32%. There are also borderline and malignant pancreatic mucinous tumors, but they are less common.
intraductal papillary mucinous neoplasms are intraducal neoplasms producing mucin that oftenThey include the head of the pancreas. Medical experts believe that they commonly occur in more men than in women, but recent studies point to the trend of the same division between gender. The affected individuals are usually aged 70 to 80 years and have abdominal pain or recurring pancreatitis. The lack of tissue invasion distinguishes benign intraducal papillary mucinous neoplasms from malignant intraducal papillary mucinous neoplasm. Compared to mucinous cystic neoplasms, they do not have intraductal papillary mucinous neoplasms of dense ovarian tree and also include pancreatic channel.
