neoplasia

 [ne″o-pla´zhah]
the formation of a neoplasm.
cervical intraepithelial neoplasia (CIN) dysplasia of the cervical epithelium, often premalignant, characterized by various degrees of hyperplasia, abnormal keratinization, and the presence of condylomata.
multiple endocrine neoplasia (MEN) a group of rare hereditary disorders of autonomous hyperfunction of more than one endocrine gland. In Type I (MEN I), called also Wermer's syndrome, there are tumors of the pituitary, parathyroid gland, and pancreatic islet cells in association with a high incidence of peptic ulcer. Type II (MEN II), called also Sipple's syndrome, is characterized by medullary carcinoma of the thyroid, pheochromocytoma, often bilateral and multiple, and parathyroid hyperplasia. Type III (MEN III), called also mucosal neuroma syndrome, resembles Type II except that parathyroid hyperplasia is rare, the mean survival time is shorter, and there may be neuromas and neurofibromas. All forms are transmitted as autosomal dominant traits.

gestational trophoblastic neoplasia  (GTN) a group of neoplastic disorders that originate in the placenta, including hydatidiform mole, chorioadenoma destruens, and choriocarcinoma.
multiple endocrine neoplasia  (MEN) a group of rare diseases caused by genetic defects that lead to hyperplasia and hyperfunction of two or more components of the endocrine system; type I is characterized by tumors of the pituitary, parathyroid glands, and pancreatic islet cells, with peptic ulcers and sometimes Zollinger-Ellison syndrome; type II is characterized by thyroid medullary carcinoma, pheochromocytoma, and parathyroid hyperplasia; type III is similar to type II but includes neuromas of the oral region, neurofibromas, ganglioneuromas of the gastrointestinal tract, and café-au-lait spots.

Patient discussion about neoplasia

Q. What is a brain tumor?

A. A brain tumour is any intracranial tumor normally either in the brain itself in the cranial nerves, in the brain envelopes, skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors). It is created by abnormal and uncontrolled cell division. Primary (true) brain tumors (which start in the brain) are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain.

Q. Is this a tumor? I felt a lump in my breast a few days ago in the shower. Is this a Tumor? Help! I'm scared.

A. If you felt a lump in your breast then you should go see your Doctor to check whether or not it is something that could be dangerous.

Q. what is carcinoid tumors? I had my appendix removed and the doctor came in the room very shocked and said it was full of carcinoid tumors. Im scared to get them somewhere else.

A. ya I have pain all the time but the doctors wont give me anything cuz im so young they don't want me hooked on anything. thank you sooo much for being so kind.

Furthermore, the neoplastic cells failed to react with histochemical stain, although the colloidal substances appeared pale.
Cases of disseminated neoplasia in bivalve mollusc species are characterized by the presence of large (2-4 times the diameter of normal hemocytes), neoplastic circulating cells that have a hyperchromatic and often pleomorphic nucleus containing 1 or more prominent nucleoli (Barber 2004), and a high nuclear-tocytoplasmic volume ratio in neoplastic cells (Mix 1975).
All positive neoplastic cells exhibited firmly fibrillary diffuse cytoplasmic staining using both TU-20 and TuJ-1 (Fig.
In conclusion, hypothyroidism, regardless of the functional state of the gonads, resulted in a delayed growth of the ascitic form of Ehrlich tumor as it reduced the liquid volume and did not reduce the number, viability, or diameter of neoplastic cells.
On histopathologic examination, the mass was composed of a proliferation of neoplastic cells organized in dense sheets in a variably dense fibrous stroma.
19,20) Therefore, the diagnosis of H/DS is based largely upon the immunophenotypic profile of neoplastic cells, per the 2008 World Health Organization classification.
The release of these molecules is also accountable for most of the symptoms observed in patients with HL, in addition to the ability of the neoplastic cells to escape from growth controls and immunosurveillance.
Mild and diffuse AMACR positivity is seen in nearly all neoplastic cells (immunoperoxidase, x200).
In the peripheral blood, the polylobated appearance of neoplastic cells has led to the term "flower cells," which are considered characteristic of ATLL (13).
In granulocytic tumors, the neoplastic cells had granular cytoplasm, and the granules had either neutrophilic or eosinophilic features.
Neoplastic cells showed enlarged and prominent nuclei.
Neoplastic lesions appear significantly darker than normal tissue; this loss of fluorescence is believed, in part, to result from interactions between the neoplastic cells and the underlying matrix, which results in loss of collagen and elastin fluorescence.
