Response: Cylindromas are benign tumors histologically similar to sweat glands. Multiple scalp cylindromas may coalesce to cover the entire scalp, resulting in the so-called โturban tumor.โ Multiple scalp cylindromas are often associated with Brooke-Spiegler syndrome. There is a rare association between cylindromas and basal cell adenoma as well as adenocarcinoma of the parotid gland. This is the first case to demonstrate the CT appearance of both the scalp and parotid gland findings in this uncommon syndrome.
