AbstractNail neoplasms include all tumors occurring in the nail or periungual apparatus tissue. While some nail tumors can be similar to tumors located on the skin, others are unique. Both benign and malignant lesions can affect the nail apparatus. In particular, early malignant tumors like melanoma and squamous cell carcinoma can present similarly to ...

CT has made possible the diagnosis of intracranial neoplasms with greater precision than other currently available neurodiagnostic studies. Because it is not always possible to determine the precise pathologic features of these neoplasms without angiography and surgical biopsy, over-reliance on CT should be avoided.

Anal cancers can be grouped into three major categories. First, anal margin lesions are usually well-differentiated, keratinized squamous cell carcinomas that are amenable to local treatment measures. Second, anal canal cancers distal to the dentate line are mostly epidermoid, nonkeratinizing, moderately differentiated tumors.

Medical Hypotheses, 1987
No satisfactory definition of a neoplasm exists. Current criteria are shown to be invalid for strictly definitional purposes. Difficulties relate in part to the difference between descriptions and explanations, and also to the status of definitional "truths".

Gastrointestinal Endoscopy Clinics of North America, 2005
Patients who present with signs and symptoms suggesting a pancreatic neoplasm typically undergo initial imaging with transabdominal ultrasound or CT. When a pancreatic mass or fullness is identified, it may represent an inflammatory mass, benign process, or malignancy. Endoscopic ultrasound (EUS) is performed commonly to further characterize the lesion,

SUMMARY In a retrospective study of neoplasms in Equidae presented to the Animal Disease Diagnostic Laboratory, Purdue University, from Jan 1, 1970, to Dec 31, 1974, data were compiled on numbers and anatomic sites of neoplasms as well as on age, sex, and breed of subjects from which the neoplasms were taken.

Nephroblastoma, or Wilms tumor, is a malignant embryonal neoplasm that is derived from nephrogenic blastemal cells, with variable recapitulation of renal embryogenesis. The pathogenesis of nephroblastoma is complex and has been linked to alterations of several genomic loci, including WT1, WT2, FWT1, and FWT2.

Burnet's concept of immunosurveillance 1 is one of the most important hypotheses of our era. He theorizes that the evolutionary purpose of cell-mediated immunity is to annihilate mutant neoplastic clones. Basic to Burnet's concept is the statistical frequency with which a neoplastic cell is produced by an error in nucleic acid replication.
