    • Signs
    • Treatment
  • Chalazion (Meibomian cyst)
    • Chronic granulomatous inflammatory (small area of inflammation) lesion
    • Meibomian or Zeis glands
    • Lipid deposition or oil like substance
    • Surrounded by lipid-laden epithelioid cells, multinucleated giant cells and lymphocytes
    • Blepharitis usually involved
  • Malignant lesions
    • Quality of tissue looks irregular
    • Changes are not consistent or predictable
    • Neovascular patterns around and within
    • Bleeding and ulceration of lesion
    • Uncharacteristically large lumps or bumps
  • 15 20 % of periocular skin lesions are Benign lesions
  • Benign lesions

    • Slow growing
    • Less inflamed
    • Shallow (not deep and invasive)
    • Well circumscribed
    • Usually, multiple lesions
  • Chalazion
    • Blockage of meibomian glands (orifices) by sebaceous secretions
    • Caused by retention of normal secretions and granulomatous tissue formation
  • Peanut butter stye...
  • External hordeolum
    • Infection of eyelid glands of Zeiss or Moll
    • Caused by Staphylococcus aureus infection of sebaceous gland opening
  • Internal hordeolum
    • Acute infection of meibomian gland
    • Chalazion with secondary infection with S Aureus
    • More chronic
    • More swollen than stye as tarsal glands are larger
    • NB! Be cautious of preseptal cellulitis
  • Other cysts
    • Cyst of Zeiss
    • Cyst of Moll
    • Epidermal inclusion
    • Epidermoid
  • Cyst of Zeiss
    • Small, non-translucent, obstruction of sebaceous gland ass with eyelash follicle
    • Contains oily secretions
  • Cyst of Moll
    • Retention cyst of lid margin
    • Round, non-tender, translucent and fluid filled
  • Epidermal inclusion
    • Implantation of epidermis into dermis following surgery
    • Slow growing, round and firm
  • Epidermoid
    Developmental along embryonic lines of closure
  • Epidermal inclusion cyst

    • Slow growing
    • Round and firm lesion
    • Common cutaneous lesions, often referred to as epidermoid, epidermal, inclusion or keratin cysts
    • Contain keratinized squamous epithelium and lipids, which may be odorous if ruptured
    • Eyelid lesions are usually solitary, mobile and less than 1 cm
    • May be congenital or may arise from trauma
  • Xanthelasma
    • Common, bilateral
    • Affects middle-aged and elderly individuals
    • Hyperlipidaemia in 1/3 of cases
    • Intracellular fat
  • Pyogenic granuloma
    • Most common acquired vascular lesion to involve the eyelids
    • Fast growing vascularized proliferation of granulation tissue
    • Fast growing, fleshy, red to pink mass which readily bleeds with minor contact
    • Usually occurs after trauma or surgery or it can be idiopathic
    • Painful
    • Differential diagnosis includes Kaposi sarcoma
    • Treatment can include use of steroid to reduce the inflammation or surgical excision at the base of the lesion
  • Molluscum contagiosum
    • Common viral skin disease caused by a large (double stranded) DNA pox virus
    • Infection usually from direct contact in children and sexually transmitted in adults
    • Typical lesion appears as a raised, shiny, white to pink nodule with a central umbilication filled with cheesy material
    • Lesion is approximately 2mm to 3mm in diameter
    • May occur in clusters or groups, particularly in immunocompromised individuals
    • Eyelid lesions may produce a follicular conjunctival reaction
    • Usually spontaneously resolves 3 to 12 months but may be treated to prevent spread or if the lesion is close to the lid margin
    • Treatment: excision, cauterization, cryotherapy, laser
  • Verruca Vulgaris
    • Common cutaneous wart caused by the epidermal infection of the human papillomavirus
    • More common in children and young adults and may occur anywhere on the skin
    • Lesions appear elevated with an irregular, hyperkeratotic papillomatous surface
    • Lesions along lid margin may cause papillary conjunctivitis
    • Tend to be self limiting but if treatment required cryotherapy or surgical excision
  • Squamous cell papilloma
    • Fibrovascular tissue covered by hyperkeratotic squamous epithelium
    • Common benign with range of clinical appearance
    • Incidence increases with age
    • Some cases involve human papilloma virus
    • Treatment: excision or cryotherapy
  • Seborrheic keratosis / Basal cell papilloma
    • Slow growing lesion
    • 'stuck on' appearance
    • Numerous
    • Differential diagnosis: pigmented basal cell carcinoma, naevus, melanoma
    • Treatment: excision, laser ablation, cryotherapy
  • Actinic keratosis
    • Yellowish rough and crusty lesions that tend to bleed easily
    • Pre-malignant: may lead to squamous cell carcinoma
    • Cause: overexposure to the sun
    • Similar look to sebaceous keratosis but looks more greasier that actinic lesions
    • Treatment: Prompt excision = immediate referral
  • Benign pigmented lesions
    • Nevus (Freckle)
    • Congenital melanocytic nevus
    • Intradermal nevus
    • Junctional nevus

    • Strawberry nevus
    • Port-wine stain / Nevus Flammeus
    • Neurofibroma
  • Nevus (Freckle)

    • Small brown macule (1-5 mm)
    • Increased melanin in the epidermal basal layer
    • Sun-exposed skin
    • Can regress completely
  • Congenital melanocytic nevus
    • Small and uniform in colour
    • Kissing or split nevus – upper and lower lid
    • May contain numerous hairs
    • Large lesions have the potential for malignancy
  • Intradermal nevus
    • Most common
    • Older patients
    • Papillomatous lesion with little pigment
    • Confined to dermis with no malignant potential
