Occurrence of basal cell epithelioma and syringocystadenoma papilliferum on sebaceous nevi is well known. But many other adnexal tumors, such as pilar or sweat gland tumours may also be associated with this dysembryoplasia. Out of 99 cases of verruco-sebaceous nevi we find 12 associated basal cell epitheliomas, 7 syringocystadenomas papilliferum and 6 benign adnexal tumors. Our report is about these 7 cases. All of these tumors appeared in adult-hood and were clinically suggesting the diagnostic of basal cell epithelioma. But, after histopathological examination was performed, they revealed to be 2 nodular hidradenomas, 1 chondroid syringoma, 1 trichilemmoma, 1 apocrine cystadenoma, 1 follicular poroma. Similar data are given by Mehregan and Pinkus in 1965 and Wilson Jones and Heyl in 1970, respectively out of 150 and 140 cases of verruco-sebaceous nevi.
