[Clinico-epidemiologic characteristics of superficial multiple basal cell carcinoma at the Dermatovenereology Clinic in Novi Sad 1986-1996].
BACKGROUND
Multiple superficial basal cell carcinomas of the skin (MSBCC) appear as a rare clinical form of basal cell carcinoma (BCC) on the trunk. The aim of this paper was to display the clinical characteristics and frequency of superficial basal cell carcinomas on the trunk.


METHODS
The examination was done on a 10-years material of the Department of Dermatological Oncology of the Dermatovenererology Clinic in Novi Sad (in the period 1986-1996). The examination included only MSBCC.


RESULTS
In the 10-year period the total number of nonmelanotic malignant epithelial tumors of the skin (NMETS) was 2218 with 22 of MSBCC with total incidence of 0.99%. The average annual number of NMETS was 221.8. The average annual number of MSBCC was 2.2. In regard to the incidence of BCC of the skin in the same period, the total number of BCC of the skin was 1220, with the incidence of MSBCC 1.80%. The total number of changes of the superficial types BCC in the examined group was 110, and the average number of changes 5. The localization of MSBCC in the examined group shows the greatest number of tumors on the skin of the back (42--38.18%), hence thorax (29--26.36%), abdomen (25--22.73%) and the least on the presternum (14--12.73%). The average period from discovery of MSBCC in the examined group until the moment of inspection was about 2.5 years. In one case nevocellular syndrome was established, MSBCC was established in 35 patients, while in 80 cases these were different types of BCC of the face, capillitium, neck, trunk and extremitites. In the examined group 22.73% patients with positive familial anamnesis in regard to malignancy. Most were pensioners (11 cases--50.00%) mainly living in towns, while agriculturers are on the second place (7 cases--31.82%) mostly living in the village. In regard to the age, it appears that increasing number of patients are in the seventh decade of life.


CONCLUSIONS
The recent literature data point to the genetic dispositions for MSBCC on the skin of the trunk, probably due to poorphotoexposition of the skin.


CONCLUSIONS
Authors principally point to the genetic pre-disposition as the main etiological factor for MSBCC of the skin of the trunk. Professional or accidental photoexposition to ultraviolet radiation, also have a secondary role. The disease mostly affects the elderly and mostly males.
