ⓘ Neoplasms ..


A neoplasm is a type of abnormal and excessive growth, called neoplasia, of tissue. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and it persists growing abnormally, even if the original trigger is removed. This abnormal growth usually forms a mass. When it forms a mass, it may be called a tumor. ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior. Malignant neoplasms are also simply known as cancers and are the focus of oncology. Prior to the abno ...

Circulating tumor DNA

Circulating tumor DNA is tumor-derived fragmented DNA in the bloodstream that is not associated with cells. ctDNA should not be confused with cell-free DNA, a broader term which describes DNA that is freely circulating in the bloodstream, but is not necessarily of tumor origin. Because ctDNA may reflect the entire tumor genome, it has gained traction for its potential clinical utility;" liquid biopsies” in the form of blood draws may be taken at various time points to monitor tumor progression throughout the treatment regimen. ctDNA originates directly from the tumor or from circulating tu ...

Congenital hemangioma

Congenital hemangiomas are of two main types Non-involuting congenital hemangioma and Rapidly involuting congenital hemangioma. They are often mistaken for an infantile hemangioma but are present at birth. They do not tend to grow after birth.

Extraskeletal myxoid chondrosarcoma

Extraskeletal myxoid chondrosarcoma is a rare low-grade malignant mesenchymal neoplasm of the soft tissues, that differs from other sarcomas by unique histology and characteristic chromosomal translocation. There is an uncertain differentiation and neuroendocrine differentiation is even possible.

Hepatoid tumor

Hepatoid tumor or hepatoid carcinoma are terms for a number of uncommon or rare neoplasms in humans, named for a visual resemblance of the cells under the microscope to those of hepatocellular carcinoma, the most common form of liver cancer. They can arise in several parts of the body, and thus form sub-types of diseases such as stomach cancer and pancreatic cancer. The WHO defines "Hepatoid carcinoma" as "An adenocarcinoma with morphologic characteristics similar to hepatocellular carcinoma, arising from an anatomic site other than the liver". In dogs it may refer to a Perianal gland tumo ...

Pancreatic neuroendocrine tumor

Pancreatic neuroendocrine tumors, often referred to as "islet cell tumors", or "pancreatic endocrine tumors" are neuroendocrine neoplasms that arise from cells of the endocrine and nervous system within the pancreas. PanNETs are a type of neuroendocrine tumor, representing about one third of gastroenteropancreatic neuroendocrine tumors GEP-NETs. Many PanNETs are benign, while some are malignant. Aggressive PanNET tumors have traditionally been termed "islet cell carcinoma". PanNETs are quite distinct from the usual form of pancreatic cancer, the majority of which are adenocarcinomas, which ...

Vulvar tumors

Vulvar tumors are those neoplasms of the vulva. Vulvar and vaginal neoplasms make up a small percentage of female genital cancers. They can be benign or malignant. Vulvar neoplasms are divided into cystic or solid lesions and other mixed types. Vulvar cancers are those malignant neoplasms that originate from vulvar epithelium, while vulvar sarcomas develop from non-epithelial cells such as bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Epithelial and mesenchymal tissue are the origin of vulvar tumors. Malignant vulvar neoplasms makes up 6% of all rep ...

Congenital hemangioma

A vascular tumor is a tumor of vascular origin; a soft tissue growth that can be either benign or malignant, formed from blood vessels or lymph vessels. Examples of vascular tumors include hemangiomas, lymphangiomas, hemangioendotheliomas, Kaposis sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular tumor. Some vascular tumors can be associated with serious blood-clotting disorders, making correct diagnosis critical. A vascular tumor may be described in terms of being highly vascularized, or poorly vascularized, referring to the degree of blood s ...
