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 ...
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 ...
Smooth muscle tumor of uncertain malignant potential, abbreviated STUMP, is an uncommon tumor of the uterine smooth muscle that may behave like a benign tumor or a cancerous tumor. This tumor should not be confused with the prostatic stromal tumor of uncertain malignant potential which may be abbreviated the same way ( STUMP ).
Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions (there are also surgical and radiation oncologists).
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
Benign neoplasms are typically, but not always, composed of cells which bear a strong resemblance to a normal cell type in their organ of origin. These tumors are named for the cell or tissue type from which they originate.
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 ...
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).
