Histopathologic variants of basal cell carcinoma correlation with sex, age and localization.

During the 6-year period (January 1, 1993 to December 31, 1998) in the Laboratory for Dermatopathology of Department of Dermatovenereology in Clinical Hospital Split, 1616 basal cell carcinomas (BCC) of a total of 323 investigated specimens were diagnosed. The incident rate varies from 92 to 114 BCC per 100,000 inhabitants in the Split region. The sex ratio in material is 1.2:1 in favor of males. The frequence of BCC increases with the advanced age in both sexes with the peak in the age group from 70 to 79 years. The most frequent location in both sexes is the nose followed by cheeks and trunk. Statistic analysis showed a significantly higher occurrence of BCC in temporal region in the males and perioral region in the females; respectively. The solid variant is the most frequent followed by superficial multicentric and solid-adenoid. Pure variants are found in 83.1% specimens, and mixed variants in 16.9%. Solid and adenoid variants are the most frequent on the nose and cheeks. According to statistics cystic variant is significantly higher on the forehead, and morpheic variant on the nose. Superficial multicentric variant is statistically more frequent on the trunk than on other locations. All specimens were reexamined and histopathologic variants were obtained. Over 2000 data are comprised which is a sufficient examination sample. In programs such as SPSS, and Graph master ver 1.12, Win95, MO'97 (Word, Excel, Access) on Pentium II 200 MHz, floppy, 64 MB RAM, HDD 2.1 GB, CD x24, HP LJet 6L, a comprehensive analysis has been performed.
