Value of ultrastructural studies in fine needle aspiration biopsy diagnosis.
We studied 156 fine needle aspiration biopsies of tumors from various locations with electron microscopy and, after processing, obtained evaluable material in 99 (63%) cases. Ultrastructural study elicited highly significant or essential findings in 39 patients (39% of the evaluable samples). In the cases requiring urgent treatment we were able to obtain an ultrastructural diagnosis in seven hours.
