| Abstract: | A case of sebaceous epithelioma on the scalp of a 50 year old female was reported. Using an electron microscope, cells from the tumor were classified into 5 stages according to their development. Furtheremore, our investigation indicate that lipid synthesis was activated in sebaceous epithelioma cells rather than in normal sebaceous cells, and can apparently be distinguished from lipid-droplet formation by degradation. These sebaceous epithelioma cells also possessed the ability to secrete which suggests that these tumor cells originated from germinative cells of the sebaceous gland rather than epidermal basal cells. |
