Abstract
We report a case of various kinds of apocrine tumors arising in nevus sebaceus. The patient was a 44-year-old man, who first had a nevus sebaceus on his left temporal region. A reddish tumor arose in it one year ago and gradually developed in size. The tumor measured 3×2×1.5cm. The tumor had some histopathological features ; those of syringocystadenoma papilliferum, tubular apocrine adenoma, apocrine hidrocystoma, and syringomatous tumor. Immunohistochemically, GCDFP-15 was positive in every portion of the tumor.
