A neoplasm (/ ˈ n iː oʊ p l æ z əm, ˈ n iː ə-/) [1] [2] is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia . The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger ...
236 Neoplasm of uncertain behavior of genitourinary organs; 237 Neoplasm of uncertain behavior of endocrine glands and nervous system. 237.0 Pituitary gland and craniopharyngeal duct. Pituitary adenoma; 237.7 Neurofibromatosis; 238 Neoplasm of uncertain behavior of other and unspecified sites and tissues 238.4 Polycythemia vera
A related category of melanocytic proliferation is superficial atypical melanocytic proliferations of uncertain significance (SAMPUS). This category, unlike MELTUMP, which implies as yet undetermined potential for metastases even after complete excision, signifies lesions without metastatic potential at time of excision but with potential to ...
A subcategory of D48.1, Neoplasm of uncertain behavior of connective and other soft tissue, has been created with more specific codes: [50] D48.11: Desmoid tumor D48.110: Desmoid tumor of head and neck; D48.111: Desmoid tumor of chest wall; D48.112: Desmoid tumor, intrathoracic; D48.113: Desmoid tumor of abdominal wall
For other types of cancer of unknown primary, a PET-CT offers uncertain benefit. [7] The pattern of spread may suggest the location of the primary site. For example, metastatic cancer found in the upper body is more likely to have an origin above the diaphragm, at sites such as the lung and breast. If the metastatic cancer appears first in the ...
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GISTs arise in the smooth muscle pacemaker interstitial cell of Cajal, or similar cells. [2] They are defined as tumors whose behavior is driven by mutations in the KIT gene (85%), [2] PDGFRA gene (10%), [2] or BRAF kinase (rare).
Detection of any deviation from what is known to be normal, such as can be described in terms of, for example, anatomy (the structure of the human body), physiology (how the body works), pathology (what can go wrong with the anatomy and physiology), psychology (thought and behavior) and human homeostasis (regarding mechanisms to keep body ...
Undifferentiated pleomorphic sarcoma (UPS), also termed pleomorphic myofibrosarcoma, [1] high-grade myofibroblastic sarcoma, and high-grade myofibrosarcoma, [2] is characterized by the World Health Organization (WHO) as a rare, poorly differentiated neoplasm (i.e., an abnormal growth of cells that have an unclear identity and/or cell of origin).
