Fine needle aspiration biopsy cytology of chondrosarcoma.

Fine needle aspirates of ten chondrosarcomas were evaluated, and the cytologic features of this tumor were described. Some malignant cells in the smears of chondrosarcoma resembled cells of an epithelial origin and could be misinterpreted as carcinoma cells. The morphologic features described for chondrosarcoma should be helpful in avoiding such a diagnostic error.

Pilomatrixoma: a pitfall in the aspiration cytology of skin tumors.

The aspirates from six tumors of pilomatrixoma were cytologically misinterpreted. The fine needle aspiration findings of these six tumors are described. The common cytologic features of pilomatrixoma are clusters of tightly arranged cells and numerous single naked nuclei. The nuclei of cells in clusters as well as the naked nuclei are vesicular, with evenly distributed chromatin and distinct nucleoli. In addition, "ghost" cells and multinucleated giant cells present in some smears can support the cytologic diagnosis of pilomatrixoma.

Anaesthesia for orthotopic allogenic liver transplantation in pigs.

Anaesthesia with a mixture of halothane, nitrous oxide and oxygen was used for allogenic liver transplantation in 24 pigs. All animals had haemodynamic disturbances due to the technique of the operation: metabolic acidosis, disturbances of bioelectric activity of the heart and electrolyte level changes. The methods of management of these disturbances are discussed. Favourable results were obtained when transfusing heparinized stored blood in place of initially used ACD blood which increased the intensity of metabolic acidosis. Details of the technique and method of anaesthesia and monitoring of animals during operation are discussed.
