Study Notes

Benign Lesions

Milia: Small, raised, round, pearly white/yellowish cystic lesions.
Keratin and protein deposits form milia beneath the skin's epidermis.
Larger than acne lesions.
Acne: Pores of the epidermis are clogged (not milia).
Associations:
- Infants: often congenital and resolve quickly.
- Adults: Trauma (e.g., laser surgery, cuts), medications (steroids, oily creams), or skin conditions can trigger milia.
- Associated with systemic diseases (e.g., lupus, fragile skin disease).
Sun factor: Prolonged sun exposure is a possible triggering factor.
Treatment: Children often do not need treatment; adults may require incision with a sharp needle to remove the lesion or expression and antibiotic ointment; cryotherapy is also a less common option..
Prevention: Avoid factors like creamy cosmetics and excessive sun exposure.

Sebaceous Cysts

Sebaceous cysts: Also known as "oily" cysts.
Cause: Clogged sebaceous glands (or glands of Zeis) in the hair follicle.
Superficial cyst = clogged sebaceous glands/Zeis.
Deep cyst = Epidermal inclusion cyst.
Distinguishing characteristic: Yellow lipid color.
Treatment: Superficial cysts can be treated by cleaning the area with alcohol, incising the cyst surface with a needle, expressing the contents with Q-tips, and then applying antibiotic ointment.
Deep cysts require excision by a specialist.
