Sebaceous Hyperplasia

Sebaceous Hyperplasia

Christine J. Ko, MD

H&E shows low-magnification view of sebaceous hyperplasia. There are normal-appearing lobules of sebocytes surrounding invaginations of epidermis that resemble the infundibulum of hair follicles image.

High-magnification view of the edge of a lobule of sebocytes shows that central sebocytes image with round to scalloped nuclei and bubbly cytoplasm are rimmed by a compressed layer of small, basaloid cells image.

  • Commonly on face

  • Rarely on the trunk or other sites


  • Yellow to flesh-colored to slightly pink papule

  • Often there is central dell
