Sebaceous hyperplasia is a common and benign disorder of the sebaceous gland. It commonly develops in middle aged to older persons, and usually presents as yellowish, scattered, umbilicated papules on the forehead, nose, and cheeks. However, several unusual variants of sebaceous hyperplasia have been reported, including a premature form, familial form, sebaceous hyperplasia et plaque, and a linear form. Here, we report an unusual case of sebaceous hyperplasia in a 37-year old woman, presenting as linear arranged, yellowish papules on the right post-auricular area. We also reviewed the literature concerning linear sebaceous hyperplasia, and found that almost all cases show the common features of younger age at onset and linear pattern arranged along Blaschko`s lines.
