We report a case of a 48‐year‐old Malay female who presented with multiple tumors arising
from a large nevus sebaceus on her right parieto‐temporal scalp. Histologically, the tumors
corresponded to a sebaceoma with carcinomatous change, a poroma and a trichoblastoma.
Immunohistochemical staining of the sebaceous tumor with p53 showed strong within the
areas of carcinomatous change, while there was negative to weak staining within the
sebaceoma‐like areas. A discussion on the potential secondary neoplasms from a nevus …
We report a case of a 48‐year‐old Malay female who presented with multiple tumors arising from a large nevus sebaceus on her right parieto‐temporal scalp. Histologically, the tumors corresponded to a sebaceoma with carcinomatous change, a poroma and a trichoblastoma. Immunohistochemical staining of the sebaceous tumor with p53 showed strong within the areas of carcinomatous change, while there was negative to weak staining within the sebaceoma‐like areas. A discussion on the potential secondary neoplasms from a nevus sebaceus ensues, with a review of this literature on multiple tumors from a nevus sebaceus.
