RESUMO
Bioptic evaluations of basaliomas require from pathologists to perform histogenetic classification, type ascertainment, TNM system classification, as well as detection of the presence or absence of tumor elements on the margins and base of excisions. The systems of histologic type classification of basaliomas utilized by pathologists are inconsistent with the terminology used by clinicians. The presented work is aimed at correlation of the current terminology of invasive basaliomas from the view of dermatologists and pathologists. The method of retrospective study was used, namely in a 100 cases of histologically verified basaliomas followed by comparisons with clinical diagnoses and catamnestic data. Average age in male patients was 66.4 year, and 67.6 year in female patients. 11 cases of histologically ascertained types of basaliomas included two cases of invasive biological characteristics detected at control examinations after 3 months, while the margins and base of the former excisions were without tumor elements. In none of the 9 cases of clinically judged invasive basaliomas the histologic picture yielded signs of tumor invasiveness. The results imply that the clinical diagnosis of a variant of basalioma may represent information of its presupposed characteristics. An important task of a pathologist is however to notify by means of accurate ascertainment of the histologic variant in cases of morpheaphorm and fibroepithelial basalioma the possible invasive character of the particular tumor.
