    444 Words  | 2 Pages

    What is a Malignant Neoplasm? A malignant neoplasm is a tumor composed of poorly differentiated cells. "Neo" means new and "plasm" refers to cells. The word neoplasm refers to abnormal overgrowth of cells rather than healthy new cell growth. It is often used interchangeably with words such as tumor and cancer. It is a cancerous tumor that grows, proliferates, infiltrates and metastasizes to other parts of the body. It can spread to surrounding tissues, through lymph nodes or through the bloodstream

  • Solid Pseudopapillary Neoplasm

    352 Words  | 2 Pages

    pseudopapillary neoplasm (SPN) of the pancreas is a rare cystic tumor that is endocrine in origin, therefore, typically found in the head and/or body of the pancreas. SPN constitutes about 1% of all pancreatic neoplasms, but advancements in diagnostic imaging have led to an increase in findings. Patients with SPN are usually asymptomatic and those with symptoms report generalized abdominal discomfort. Lab values used to evaluate the pancreas are usually within normal limits. Because these neoplasms are typically

  • Myeloproliferative Neoplasms

    977 Words  | 4 Pages

    Myeloproliferative neoplasms (MPNs) are a clonal disease of myeloid stem cells that are characterized by myeloid cell proliferation, bone marrow (BM) fibrosis, and symptoms associated with the accompanying peripheral blood cell abnormalities. The World Health Organization (WHO) provides diagnostic criteria for the following MPN subtypes: chronic myelogenous leukemia; BCR-ABL1–positive; polycythemia vera (PV); essential thrombocythemia (ET); primary myelofibrosis (PMF); chronic neutrophilic leukemia;

    plastic/myeloproliferative neoplasms In the 2008 WHO Classification of myeloid neoplasms [1], the myelodysplastic/myeloproliferative neoplasm (MDS/MPN) category are principally characterized by features overlapping between Myelodysplastic Syndrome (MDS) and Myeloproliferative Neoplasms (MPN) [2]. This category includes the following disease entities: chronic myelomonocytic leukemia (CMML), atypical chronic myeloid leukemia, BCR-ABL1 negative (aCML), juvenile myelomonocytic leukemia (JMML), Myelodysplastic/myeloproliferative

  • Essay on Salivary Gland Tumors

    2555 Words  | 11 Pages

    INTRODUCTION: Salivary gland tumors are a morphologically diverse group of neoplasms, which may present considerable diagnostic and management challenges for the pathologist and surgeon. Salivary gland tumors are rare with an overall incidence in the western world of about 2.5 to 3.0 per 100,000 per year. About 80% of all lesions are benign; hence salivary malignancies are particularly rare, comprising less than 0.5% of all malignancies and about 5% of cancers in the head and neck. (1) Most

  • Paraganglioma Case Study

    664 Words  | 3 Pages

    Paraganglioma is a rare neoplasm of neuroendocrine origin which may develop at many different anatomical sites including head and neck, thorax, and abdomen. The occurrence of paraganglioma in lower spine is rare, but well established as one of the differential. The investigation of choice pre-operatively is magnetic resonance imaging4, which usually shows a very well circumscribed partially cystic mass which is iso- or hypointense to spinal cord on T1-weighted images, and hyperintense on T2-weighted

  • LAM Lung Disease

    similar traits, only it is much more concentrated. LAM plagues the lungs with benign tumors that eventually cause sclerosis of the tissues. This results in increased difficulty in aspiration as the lungs struggle to expand and contract. In time, these neoplasms result in cyst formation on the lungs along with muscle hardening. Eventually, lungs can succumb to pneumothorax, or collapsed lung. Pleural effusions may also develop as fluid gathers between damaged spaces within the lungs increasing difficulty

    an image; Just if there should arise an occurrence of therapeutic picture division the point is to: Study anatomical structure, build up an Area of Interest i.e. discovers neoplasm (tumor), injury and distinctive variations from the norm, live tissue volume to live development of neoplasm (likewise diminish in size of neoplasm with treatment) and encourage in treatment arranging before radiation therapy; in radiation dosage estimation. Programmed division of medicinal pictures is a hard assignment

  • Overexpression Case Study

    p16INK4a overexpression in pre-malignant lesions Several pieces of evidence suggested that the ability to bypass senescence is the main molecular mechanism involved in the progression of pre-malignant to malignant cells (Braig 2005; Collado 2007). This hypothesis is based on the concept of oncogene-induced senescence, which was established after demonstration of p53- and p16Ink4a - mediated senescent-like arrest in response to expression of oncogenic Ras in normal primary cells (Collado 2007).

  • Papillomatosis: Radial Scars

    564 Words  | 3 Pages

    Radial scars are benign pseudo infiltrative lesions of uncertain significance. They are characterized by a fibro elastotic core with entrapped ducts, surrounded by radiating ducts and lobules displaying variable epithelial hyperplasia, adenosis, duct ectasia, and papillomatosis. Some authors have suggested using the term "radial scar" for lesions measuring was reserved for lesions measuring 1 cm or larger. (Guray and Sahin,2006) Radial scars may serve for the development of atypical epithelial proliferations
