Monolayer cultures of cells originating from ultrasonically guided fine needle aspiration biopsies

Explantation of small samples of tissue obtained by ultrasonically guided fine needle aspiration biopsy (0.6 mm outer diameter) from intraabdominal solid masses was performed in 25 patients. In 7 cases, the material was taken from nonmalignant tissue and in 18 from malignant lesions. Growth during 30 days or more obtained in 1 of the 7 nonmalignant cases and in 7 of the 18 malignant cases. The morphological appearance of three cultures in monolayer is demonstrated.
