What is Sebaceous Hyperplasia?
Sebaceous hyperplasia is a skin condition in which a person develops small, yellowish growths, usually on the face. A variant of this condition, known as Fordyce's condition causes tiny yellow dots in groups and sometimes in sheets on the lips, inside the mouth, and sometimes on the genital skin. In both conditions, the small, yellow spots represent an overgrowth of sebaceous glands.
Neither sebaceous hyperplasia or Fordyce's condition is dangerous. Sebaceous hyperplasia can be difficult to clinically differentiate from basal cell carcinoma. Often multiple lesions which are similar are present. They do not tend to bleed as easily as do basal cell carcinomas.

Treatment for Sebaceous Hyperplasia
Sebaceous hyperplasia is harmless and does not require any treatment. However, individual lesions may be removed by light cautery, diathermy or laser vaporization.
When the lesions are severe, extensive or disfiguring, oral isotretinoin or, in females, antiandrogens, may help improve the appearance. Sebaceous gland hyperplasia can effectively be treated with a number of cosmetic procedures including minor surgery, liquid nitrogen freezing, and, most effectively, with laser therapy.
