Title: MALIGNANT EYELID TUMOURS


1
MALIGNANT EYELID TUMOURS
1. Basal cell carcinoma
2. Squamous cell carcinoma
3. Meibomian gland carcinoma
4. Melanoma
5. Kaposi sarcoma
6. Merkel cell carcinoma 7. Treatment
2
Basal Cell Carcinoma - Important Facts
1. Most common human malignancy
2. Usually affects the elderly
3. Slow-growing, locally invasive
4. Does not metastasize
5. 90 occur on head and neck
6. Of these 10 involve eyelids
7. Accounts for 90 of eyelid malignancies
3
Frequency of location of basal cell carcinoma
Lower lid - 70
Medial canthus - 15
Upper lid - 10
Lateral canthus - 5
4
Nodular basal cell carcinoma
Early
Advanced
  • Slow progression
  • Shiny, indurated nodule
  • May destroy large portion of eyelid
  • Surface vascularization

5
Ulcerative basal cell carcinoma (rodent ulcer)
Early
Advanced
Chronic ulceration
Raised rolled edges and bleeding
6
Sclerosing basal cell carcinoma
Advanced
Early
  • Spreads radially beneath normal
  • epidermis
  • Indurated plaque with loss of lashes
  • May mimic chronic blepharitis
  • Margins impossible to delineate

7
Histology of basal cell carcinoma
Cell nests in fibrous stroma
Downgrowth from epidermis of small, dark atypical
basal cells
Peripheral palisading
8
Squamous cell carcinoma
  • Less common but more aggressive than BCC
  • May arise de novo or from actinic keratosis
  • Predilection for lower lid

Ulcerative
Nodular
  • Hard, hyperkeratotic nodule
  • Red base
  • May develop crusting fissures
  • Borders sharply defined, indurated
  • and elevated
  • No surface vascularization

9
Histology of squamous cell carcinoma
Prominent nuclei and abundant acidophilic
cytoplasm
Variable sized groups of atypical epithelial
cells within dermis
Keratin pearl
10
Meibomian gland carcinoma
  • Very rare aggressive tumour with 10 mortality
  • Predilection for upper lid

Nodular
Hard nodule may mimic a chalazion
Very large tumour
Spreading
Diffuse thickening of lid margin and loss of
lashes
Conjunctival invasion may mimic chronic
conjunctivitis
11
Histology of meibomian gland carcinoma
Cells stain positive for fat
Cells contain foamy vacuolated cytoplasm and
large hyperchromatic nuclei
12
Melanoma
Nodular
Superficial spreading
From lentigo maligna (Hutchinson freckle)
  • Plaque with irregular
  • outline
  • Affects elderly
  • Blue-black nodule with
  • normal surrounding skin
  • Slowly expanding
  • pigmented macule
  • Variable pigmentation
  • May be non-pigmented

13
Kaposi sarcoma
  • Vascular tumour occurring in patients with AIDS
  • Usually associated with advanced disease
  • Very sensitive to radiotherapy

Advanced
Early
May ulcerate and bleed
Pink, red-violet lesion
14
Merkel cell carcinoma
  • Highly malignant with frequent metastases at
    presentation
  • Fast-growing, violaceous, well-demarcated nodule
  • Intact overlying skin
  • Predilection for upper eyelid

15
Treatment Options
1. Surgical excision
  • Method of choice

2. Radiotherapy
  • Small BCC not involving medial
  • canthus
  • Kaposi sarcoma

3. Cryotherapy
  • Small and superficial BCC
  • irrespective of location
  • Adjunct to surgery in selected cases

Mustarde cheek rotation flap for large defect
Tenzel flap for moderate defect
17
Eyelid-sharing procedure
Extensive sclerosing BCC
Total excision of lower lid
Tarsoconjunctival flap
Appearance after healing
Reconstruction of posterior lamella
Reconstruction of anterior lamella with
skin graft
