Spinal Seeding of Cerebellar Pilocytic Astrocytoma and Spontaneous Regression of Tumor: a Case Report
Cerebellar pilocytic Astrocytoma is a benign tumor, acounts for 80% of all cerebellar Astrocytoma, and has a relatively good prognosis. This tumor usually presents with Ataxia and in the case of hydrocephaly with raised intracranial pressure signs such as headeach, and vomiting. Treatment of this tumor is complete resection and if hydrocephally is present V.P. shunt should be inserted. In the c...
متن کاملTumor Self-Seeding by Circulating Cancer Cells
Cancer cells that leave the primary tumor can seed metastases in distant organs, and it is thought that this is a unidirectional process. Here we show that circulating tumor cells (CTCs) can also colonize their tumors of origin, in a process that we call "tumor self-seeding." Self-seeding of breast cancer, colon cancer, and melanoma tumors in mice is preferentially mediated by aggressive CTCs, ...
متن کاملTumor Self-Seeding: Bidirectional Flow of Tumor Cells
Circulating tumor cells are responsible for seeding metastatic growth at distant sites. Kim et al. (2009) now discover that circulating tumor cells can reinfiltrate tumors at their primary organs and promote tumor progression.
متن کاملPleural effusion from pleuroperitoneal communication
A 52yearold woman with endstage renal disease for chronic glomerulonephritis was started on inpatient peritoneal dialysis (PD). We increased infusion volume of PD exchange every 2 days without observing any symptoms, including respiratory symptoms. After changing infusion volume on the 5th day, the patient complained of dyspnea and continuous cough. Decreased breath sounds were noted in the rig...
متن کاملRisk of tumor cell seeding through biopsy and aspiration cytology
Cancer cells, besides reproducing uncontrollably, lose cohesiveness and orderliness of normal tissue, invade and get detached from the primary tumor to travel and set up colonies elsewhere. Dislodging neoplastically altered cells from a tumor during biopsy or surgical intervention or during simple procedure like needle aspiration is a possibility because they lack cohesiveness, and they attain ...
