A glomus tumor (also known as a "solitary glomus tumor" [ 1]) is a rare neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot. [ 2]: 670 They account for less than 2% of all soft tissue tumors. [ 3] The majority of glomus tumors are benign, but they can also show malignant features. [ 4]
In general, tumor size (diameter) is described as small (less than 1.5 cm), medium (1.5 to 2.5 cm), large (2.5 to 4.0 cm) and giant (more than 4.0 cm). (Note: 1 inch = 2.54 cm) Radiologists reporting on MRI scans use the Koos Grading Scale which relates tumor size to its proximity to the brainstem and nearby cranial nerves.
A lipoma is a benign tumor made of fat tissue. [ 1] They are generally soft to the touch, movable, and painless. [ 1] They usually occur just under the skin, but occasionally may be deeper. [ 1] Most are less than 5 cm (2.0 in) in size. [ 2] Common locations include upper back, shoulders, and abdomen. [ 4]
Non-small cell lung cancer (NSCLC) is the most common form of lung cancer, accounting for 80-85% of all cases. It develops when abnormal lung cells grow uncontrollably, forming a tumor. There are ...
The prognosis of phyllodes tumor is good with an overall 87% 10-year survival rate. [5] After wide-margin surgical excision, 98.7% of benign phyllodes tumors and 80% of borderline were cured. [25] In rare cases where the tumor has metastasized, the prognosis is poor. [5] This most commonly occurs in cases of malignant grade phyllodes tumor. [5]
Resection of the tumor with a 1-cm margin is sufficient and more radical resections add morbidity without benefit. [25] The clinical issues of exact surgical indications for tumor size are controversial. The decision of appropriate laparoscopic surgery is affected by tumor size, location, and growth pattern. [27]
Gestational choriocarcinoma is a form of gestational trophoblastic neoplasia, which is a type of gestational trophoblastic disease (GTD), that can occur during pregnancy. It is a rare disease where the trophoblast, a layer of cells surrounding the blastocyst, undergoes abnormal developments, leading to trophoblastic tumors.
Ultrasonography of liver tumors involves two stages: detection and characterization. [1] Tumor detection is based on the performance of the method and should include morphometric information (three axes dimensions, volume) and topographic information (number, location specifying liver segment and lobe/lobes). The specification of these data is ...
