Efforts to investigate the progression of events that cause human cells to become neoplastic in response to ionizing radiation have been aided by the development of tissue culture systems of epithelial cells. In the present study, nontumorigenic human epidermal keratinocytes immortalized by adenovirus type 12 and simian virus 40 have been transformed by exposure to x-ray irradiation. Such trans...

The finding of large granular cells is relatively frequent when reviewing a blood smear for lymphocytosis (or any other reason). presence these opens the question as if they are part T-cell non-clonal reactive process or indicate clonal population (yet not necessarily neoplastic).

Fine needle aspiration (FNA) salivary shows good excellent sensitivity and specificity differentiating a neoplastic from non-neoplastic process diagnosing common tumors su...
