Glomus tumor with mucinous change
نویسندگان
چکیده
Glomus tumors are relatively uncommon neoplasms arising from modified smooth muscle cells that are normally found in specialized arteriovenous shunts in acral sites, especially the fingertips. This distribution reflects their function because the arteriovenous anastomoses of these areas, also known as the SucquetHoyer canals, are involved in temperature regulation. Sucquet-Hoyer canals are lined by endothelial cells, have several layers of glomus cells in their walls, and connect an afferent arteriole to an efferent venule.

Ovarian cancer is the most lethal gynecologic malignancy. The surface epithelial tumor is the most common type of ovarian cancer. Among these, the mucinous tumors account for 10-15% of ovarian tumors. Mucinous ovarian tumors are among the most difficult ovarian neoplasms for surgical pathologists to interpret. Mucinous tumors sometimes coexist with other surface epithelial tumors. Therefore, ma...
متن کاملUnusual gastric tumors and tumor-like lesions: Radiological with pathological correlation and literature review
Although gastric tumors have overlapping radiologic appearances, some unusual tumors may present specific imaging features. Using multidetector computed tomography (MDCT), with water as a negative oral contrast agent and intravenous contrast medium, can provide critical information for the diagnosis of gastric diseases. In addition, MDCT can evaluate the involvement of the gastric wall and extr...

Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma). In patients with mucinous adenocarcino...
متن کاملGlomus Tumors: Symptom Variations and Magnetic Resonance Imaging for Diagnosis
BACKGROUND The typical clinical symptoms of glomus tumors are pain, tenderness, and sensitivity to temperature change, and the presence of these clinical findings is helpful in diagnosis. However, the tumors often pose diagnostic difficulty because of variations in presentation and the nonspecific symptoms of glomus tumors. To the best of our knowledge, few studies have reported on the usefulne...
