MC Wong 王夢貞 and KK Jong 莊國坤

Abstract
This is a case report of a woman who presented with a yellowish scalp nodule. Skin biopsy revealed mixed skin adnexal tumour with components of trichoblastoma, syringocystadenoma papilliferum and sebaceous neoplasm that might arise from a naevus sebaceus. It is an uncommon finding to have different tumours arising from the same naevus sebaceus.
