RESUMO
A total of 799 cases of papillary bladder tumors were reviewed using both Franksson and Koss classifications. We report the results of a comparative analysis of the two classifications. No correlation between the histologic gradings in the two classifications emerges, especially regarding papilloma (Franksson, 39.3 per cent; Koss, 2.3 per cent). In both classifications recurrences are more frequent as the degree of malignancy increases, although recurrence cannot be excluded even in the lowest grades. As a result of our study, it appears that cellular anaplasia rather than invasion is a better criterion for reliable histoprognostic evaluation of papillary bladder tumors.

The Authors report two cases of hydatid cysts localized in the soft tissues of the thigh and in para-renal region respectively. In both cases the cystic nature of the lesion was revealed by echography while the common serologic and hematologic preoperative tests did not show pathologic values. The working diagnosis was traumatic or developmental lesion and the patients were undergone to fine needle aspiration (FNA) cytology which permitted to make the unexpected diagnosis of hydatid cysts. The enzyme linked immunosorbent assay for echinococcus, done at the time in monitoring the disease, was positive only in one case. Although the routine use of FNA cytology for the diagnosis of echinococcosis should be discouraged, this procedure may represent a real aid in the definitive diagnose of clinically unsuspected hydatid cysts.
