Glomus tumor can rarely arise in the central nervous system as a sella turcica mass. In this article, we report a case of sellar glomus tumor in a female patient who presented at the age of 8 years...

Purpose: Gain-of-function mutations of enhancer of Zeste homolog 2 ( EZH2 ) occur frequently in diffuse large B-cell lymphomas and in follicular lymphomas. However, the frequency of EZH2 mutation in Chinese follicular lymphomas and the potential targets affected by this mutation are unknown. Experimental Design: We determined EZH2 codon 641 mutations in Chinese follicular lymphomas ( n = 124) and compared them with Western follicular lymphomas ( n = 70) using a sensitive pyrosequencing assay. Ge...

With advances in immunohistochemical technology and growing knowledge of the molecular genetics of tumors, immunohistochemistry is playing an increasingly important role in providing genetic information for tumors. Specific chromosomal translocations can be demonstrated through detection of the protein product of one of the genes involved in gene fusion (such as BCL2, cyclin D, and ALK). Some mutations can be detected by (1) aberrant localization of the protein product (such as β-catenin and nuc...

Lymphadenopathy is a common occurrence in IgG4-related disease; it can appear before, concurrent with, or after the diagnosis of this disease, which is characterized by tumefactive sclerosing inflammatory lesions predominantly affecting extranodal sites, such as the pancreas, salivary gland, and lacrimal gland. Although multiple lymph node groups are commonly involved, constitutional symptoms are absent. The lymph nodes can show a broad morphologic spectrum, including multicentric Castleman dise...

IgG4-related disease is a newly recognized fibro-inflammatory condition characterized by several features: a tendency to form tumefactive lesions in multiple sites; a characteristic histopathological appearance; and—often but not always—elevated serum IgG4 concentrations. An international symposium on IgG4-related disease was held in Boston, MA, on 4–7 October 2011. The organizing committee comprising 35 IgG4-related disease experts from Japan, Korea, Hong Kong, the United Kingdom, Germany, Ital...

Solid pseudopapillary neoplasm, an uncommon, intriguing, low-grade malignant tumor of the pancreas, can exceptionally occur in extrapancreatic sites. We report 1 such case occurring as an ovarian primary in a 25-year-old woman, who presented with abdominal fullness. She remained well 12 years after resection of the 1.7-kg right ovarian tumor. Histologically, the tumor showed a solid, dehiscent, and pseudopapillary growth, traversed by fibrous septa and arborizing blood vessels. The polygonal tum...

Enteropathy-associated T-cell lymphoma (EATL), an uncommon lymphoma of intestinal intraepithelial T lymphocytes, occurs with a higher frequency in northern Europe due to association with celiac disease. Data on the occurrence of EATL in the Asian population, among whom celiac disease is very rare, a
