Bumps and Cysts Flashcards
Hordeolum is a bacterial infection by what bacteria
Staph Aureus of the epiderm of the sebaceous glands of the eyelid.
External hordeolum is an infection of
vs internal
The Gland of Zeiss and moll is external
Internal is infection of the meibomian gland.
What is in the hordeolum abscess
PMN leukocytes (neutrophils) and necrotic tissue –> pus
Signs of sebaceous gland carcinoma
Recurrent, lid thickening, madarosis
Pyogenic Granuloma
Overgrowth on the conj side. Investigate lesion, evert lids- look for inflammatory mass on conj side.
Treatment for hordeolum
Hot, moist compress
Lid scrubs with mild soaps, massage
Topical antibiotics (Erythromycin, neopolydex, bacitracin)
Oral antibiotics (doxy 100mg BID or Augmentin 500mg BID- amoxicillin + clavulonic acid)
Polysporin components
Bacitracin (gram pos) and polymyxin (gram neg)
What can cause preseptal cellulitis
Sinuses, hordeola, dacryo-adenitis/cystitis.
Post trauma or insect bite.
Most common inflammatory lesion of the eyelid
Chalazion
Anterior and interior chalazion
Anterior- Zeis gland
Interior- Meibomian glands
Chalazia Pathology
Lipid Products escape gland and invade surrounding tissue –> Granulomatous inflammatory response. Increased number of macrophages, epithelioid cells, and multinucleated giant cells.
3 immune cells involved in chalazion granuloma
Macrophages, epithelia cells, and multinucleate giant cells
Chalazion histology
Shows lipogranuloma- empty space with surrounding epithelioid and foamy multinucleated cells.
Nuceli have foamy cytoplasm with ingested lipid material.
Study showed that __% of chalazia resolved with hot compresses or compresses w topical antibiotics.
20%
Those that failed had been present longer than 2 months.
Treatment options for chalazion
Warm compress
Steroid injection
Excision/I&C
