hordeolum
chalazion
cysts
milia

internal hordeolum
staph abscess of MG
WC, lid massage, surgery
exernal hordeolum
staph abscess of lash follicle/zeis
WC, epilation
chalazion
MG obstruction
WC, massage
cyst of moll
cyst of moll/sweat glands
translucent, bluish tinge
cyst of zeis
obstructed zeis gland ass w/ hair follicle
non-translucent
sebaceous cyst
blocked sebaceous glands, floppy tag
epidermal inclusion cyst
implantation of epidermis into dermis
round, firm, looks like skin
dermoid cyst
sequestered skin during embryogenic development
subcut or deeper at lateral brow
milia
occlusions of hair follicles/seb glands
are hordeolums infections or blockages?
infections
are chalazions infections or blockages?
blockages
xanthelasma
multiple yellow plaques
molluscum contagiosum
infection by pox virus - affects children
pale, waxy nodules bigger than milia
herpes zoster ophthalmicus
unilaterial along a nerve - caused by VZV
in elderly and immunocompromised
herpes simplex
prodromal lid tingling
vesicles, swelling
benign eyelid tumor examples
