Definition / general
- Very common
- 90% of eyelid malignancies
- Probably secondary to sunlight
- Rarely invades orbit or nose
- Arises from cutaneous surface of eyelid (usually lower lid and medial canthus), only rarely from conjunctiva
- Frozen section review of margins is helpful in reducing recurrence
- Excision is important to preserve vision, since tumors may prevent proper eyelid closure and cause corneal exposure and ulceration
Case reports
- 34 year old woman with meningeal carcinomatosis due to basal cell carcinoma (Hum Pathol 1985;16:530)
Gross description
- Ulcerated, pigmented, superficial or sclerosing
Microscopic (histologic) description
- Subtypes:
- Nodular and nodular-ulcerative (anastomosing nests and cords of proliferative epidermal basal cells with minimal cytoplasm, dark nuclei and nuclear palisading at periphery)
- Cystic (central necrosis with cystic spaces)
- Multicentric
- Morphea (infiltrates into dermis as branching cords of cells within a dense stroma; margins are difficult to assess clinically)
