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 ...

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,

Frequent GNAQ and GNA14 Mutations in Hepatic Small Vessel Neoplasm
American Journal of Surgical Pathology, 2018Hepatic small vessel neoplasm (HSVN) is a recently described infiltrative vascular neoplasm of the liver, composed of small vessels. Although the infiltrative nature can mimic angiosarcoma, HSVN are thought to be benign or low-grade neoplasms because ...

Sebaceous skin tumors are classified into sebaceous adenoma, sebaceoma, and sebaceous carcinoma. An additional group of cystic sebaceous tumors indicate the Muir-Torre syndrome (MTS). Cystic sebaceous tumors are considered as morphologic variants of the 3 main categories.

Vascular neoplasms in the broad sense represent a very common group of tumors or hamartomas that show great variability in gross appearance, microscopic appearance, and clinical course. Generally, neoplasms are composed of one cell type, but vascular neoplasms are collections of endothelial-lined tubes or tubules with connective tissue walls that may ...

Experience with 2 cases of neurally-derived perineal masses is described. A relevant review of the literature spanning 50 years revealed 36 cases of perineal neoplasm of diverse nature, disclosing that such lesions typically present as otherwise asymptomatic enlarging masses and may comprise a broad spectrum of neoplasia with diagnosis and prognosis ...

Current Opinion in Oncology, 1997
Thymomas are infrequent and relatively indolent mediastinal tumors. They are usually encapsulated and readily removed. Invasive tumors, even if completely resected, require additional therapy. Although efforts have been made to relate histopathologic characteristics to outcome, the most important prognostic factors are stage and ability to achieve ...

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.
