Introduction: Solid and cystic papillary epithelial neoplasm of pancreas is a rare neoplasm with low malignant potential which often occurs in young women. The tumor is usually large and encapsulated. Microscopic examination reveals small round cells with papillary-configuration in a delicate vascular stroma. Case Report: The cases presented in this report were 2 women at the age of 15 & 26...
Circulating tumor cells (CTC) are cells that have detached from primary tumors and circulate in the bloodstream where they are carried to other organs, leading to seeding of new tumors and metastases. CTC have been known to exist in the bloodstream for more than a century. With recent progress in the area of micro- and nanotechnology, it has been possible to adopt new approaches in CTC research...
Hepatocellular cancer is one of the most common and fatal cancer tumor worldwide. However, the obtained results are questionable in terms of medical treatment of hepatocellular cancer. The muscle, soft tissue and cutaneous metastases of hepatocellular cancer, for instance, are rare and may result from interventional procedures. Seeding of tumor along the biopsy needle upon percutaneous biopsy i...
Metastasis, the life threatening aspect of cancer, is a systemic disease process. Considerable progress has been made in recent years regarding how tumor cells circulating in the blood and lymphatic systems interact with and extravasate into secondary sites, and what determines whether these disseminated tumors cells survive, remain dormant or go on to form macrometastases. New insights into th...
Cheatgrass (Bromus tectorum L.) is the most widespread invasive weed in sagebrush ecosystems of North America. Restoration of perennial vegetation is difficult and land managers have often used introduced bunchgrasses to restore degraded sagebrush communities. Our objective was to evaluate the potential of ‘Vavilov’ Siberian wheatgrass (Agropyron fragile [Roth] P. Candargy) to establish on chea...
The cobblestone-area forming cell (CAFC) assay permits a direct measurement of the seeding of primitive and more mature murine hematopoietic stem cell subsets by comparing the number of CAFC in the original transplant with the number of CAFC retrieved from bone marrow (BM) and spleen after transplantation. We found no differences in seeding efficiency between the more mature and primitive CAFC ...
tissues. 0.7–0.9% of patients with a malignant tumour at any site can develop a cutaneous or subcutaneous metastasis after percutaneous procedures [2]. The duration between the onset of tumour seeding and the previous percutaneous needle biopsy has been shown to vary widely. Clinically, tumour deposits are observed as painful cutaneous or subcutaneous nodules, typically round or oval, with well...
Background and study aims Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esopha...
