05 malignant eyelid tumours

  1. 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. 2. Basal Cell Carcinoma - Important Facts 1. Most common human malignancy 2. Usually affects the elderly 3. Slow-growing, locally invasive 5. 90% occur on head and neck 6. Of these 10% involve eyelids 7. Accounts for 90% of eyelid malignancies 4. Does not metastasize
  3. 3. Frequency of location of basal cell carcinoma Lower lid - 70% Medial canthus - 15% Upper lid - 10% Lateral canthus - 5%
  4. 4. Nodular basal cell carcinoma Early <ul><li>Shiny, indurated nodule </li></ul><ul><li>Surface vascularization </li></ul><ul><li>Slow progression </li></ul>Advanced <ul><li>May destroy large portion of eyelid </li></ul>
  5. 5. Ulcerative basal cell carcinoma (rodent ulcer) Early Chronic ulceration Advanced Raised rolled edges and bleeding
  6. 6. Sclerosing basal cell carcinoma <ul><li>Indurated plaque with loss of lashes </li></ul>Advanced <ul><li>Spreads radially beneath normal </li></ul><ul><li>epidermis </li></ul>Early <ul><li>May mimic chronic blepharitis </li></ul><ul><li>Margins impossible to delineate </li></ul>
  7. 7. Histology of basal cell carcinoma Downgrowth from epidermis of small, dark atypical basal cells Peripheral palisading Cell nests in fibrous stroma
  8. 8. Squamous cell carcinoma <ul><li>Predilection for lower lid </li></ul><ul><li>Hard, hyperkeratotic nodule </li></ul><ul><li>Less common but more aggressive than BCC </li></ul><ul><li>May develop crusting fissures </li></ul><ul><li>May arise de novo or from actinic keratosis </li></ul>Ulcerative <ul><li>No surface vascularization </li></ul><ul><li>Red base </li></ul><ul><li>Borders sharply defined, indurated </li></ul><ul><li>and elevated </li></ul>Nodular
  9. 9. Prominent nuclei and abundant acidophilic cytoplasm Variable sized groups of atypical epithelial cells within dermis Histology of squamous cell carcinoma Keratin ‘pearl’
  10. 10. Meibomian gland carcinoma Spreading Nodular <ul><li>Very rare aggressive tumour with 10% mortality </li></ul><ul><li>Predilection for upper lid </li></ul>Hard nodule; may mimic a chalazion Very large tumour Diffuse thickening of lid margin and loss of lashes Conjunctival invasion; may mimic chronic conjunctivitis
  11. 11. Histology of meibomian gland carcinoma Cells stain positive for fat Cells contain foamy vacuolated cytoplasm and large hyperchromatic nuclei
  12. 12. Melanoma From lentigo maligna ( Hutchinson freckle) Nodular <ul><li>Blue-black nodule with </li></ul><ul><li>normal surrounding skin </li></ul><ul><li>Plaque with irregular </li></ul><ul><li>outline </li></ul><ul><li>Variable pigmentation </li></ul><ul><li>Affects elderly </li></ul><ul><li>Slowly expanding </li></ul><ul><li>pigmented macule </li></ul><ul><li>May be non-pigmented </li></ul>Superficial spreading
  13. 13. Kaposi sarcoma Advanced Early Pink, red-violet lesion <ul><li>Vascular tumour occurring in patients with AIDS </li></ul><ul><li>Usually associated with advanced disease </li></ul><ul><li>Very sensitive to radiotherapy </li></ul>May ulcerate and bleed
  14. 14. Merkel cell carcinoma <ul><li>Highly malignant with frequent metastases at presentation </li></ul><ul><li>Fast-growing, violaceous, well-demarcated nodule </li></ul><ul><li>Intact overlying skin </li></ul><ul><li>Predilection for upper eyelid </li></ul>
  15. 15. Treatment Options 3. Cryotherapy 2. Radiotherapy <ul><li>Small BCC not involving medial </li></ul><ul><li>canthus </li></ul>1. Surgical excision <ul><li>Method of choice </li></ul><ul><li>Small and superficial BCC </li></ul><ul><li>irrespective of location </li></ul><ul><li>Adjunct to surgery in selected cases </li></ul><ul><li>Kaposi sarcoma </li></ul>
  16. 16. Lower eyelid reconstruction following tumour excision Mustarde cheek rotation flap for large defect Tenzel flap for moderate defect Direct closure of small defect a b a b b
  17. 17. Eyelid-sharing procedure Reconstruction of posterior lamella Extensive sclerosing BCC Total excision of lower lid Tarsoconjunctival flap Reconstruction of anterior lamella with skin graft Appearance after healing
