What Is Sebaceous Hyperplasia?
Sebaceous gland hyperplasia is caused by the enlargement of normal sebaceous glands in the skin and belongs to benign lesions. Trauma and local chronic inflammatory stimuli may be related to skin lesion formation. Can be divided into premature sebaceous hyperplasia and senile sebaceous hyperplasia. Histopathology showed an increase in the number of mature sebaceous glandular lobes.

Causes of sebaceous hyperplasia
- The exact etiology and pathogenesis are unknown. The disease is caused by an increase in the normal sebaceous glands of the skin. Trauma and local chronic inflammatory stimuli may be related to skin lesion formation.
Clinical manifestations of hyperplasia of sebaceous glands
- Can be divided into premature sebaceous hyperplasia and senile sebaceous hyperplasia. Premature sebaceous hyperplasia usually develops during the developmental period or during the age of 20 to 30 years. Skin lesions are more common on the face, especially the lower jaw. It is a 1 to 2 mm yellow papule, which can be promoted into slices. There is an umbilical cavity in the center of individual skin lesions. Senile hyperplasia of sebaceous glands, which can be single or multiple, occur in the forehead and cheeks, usually scattered, hemispherical bulges, sometimes lobular, 2 to 3 mm in diameter, soft, pale yellow or yellow, central lesions A umbilical depression is common. Histopathology showed proliferative sebaceous glandular lobules, well differentiated.
Diagnosis of sebaceous hyperplasia
- Clinically there are typical skin lesions and histopathology. The number of lobes of sebaceous glands in a single group should be more than 15 to be diagnosed as the disease. The disease needs to be distinguished from sebaceous nevus, sebaceous adenoma, and nasal nodules.
Sebaceous Hyperplasia Treatment
- The disease generally does not require treatment. If the appearance is significantly affected, electrocautery, freezing, laser or surgical resection can be performed.
