A 68-year-old man presents with a slowly growing lump on the lower lid margin that bleeds when he rubs it and never quite heals. It has been there for a year, gradually enlarging. He worked outdoors for decades. Vision is 6/9 and the eye itself is comfortable.
Examination Findings
A 7 mm pearly, waxy nodule on the right lower lid margin with surface telangiectasia and a small central ulceration; lashes are distorted around it. The lesion involves the lid margin. No palpable lymph nodes. Ocular examination otherwise normal. The medial canthus is not involved.
Investigations
Incisional or excisional biopsy with histopathology confirms the diagnosis and subtype. Lid margin involvement is mapped carefully for surgical planning. Photography documents the lesion.
Questions to Think About
- Which clinical features mark this as malignant rather than a benign lid lump?
- Why does lid-margin involvement change the surgery?
- Which location would be most worrying?
Diagnosis
Basal cell carcinoma of the right lower eyelid margin.
Reasoning
Reasoning: A pearly nodule with telangiectasia, central ulceration and lash distortion in a sun-exposed older adult is basal cell carcinoma until proven otherwise — the pearly rolled edge and the non-healing ulcer are the classic warnings, and benign lumps (chalazia, papillomas) do not ulcerate and bleed like this. Lid-margin involvement matters because the tumour must be removed with clear margins while reconstructing a functioning lid — form and function together. Diagnosis: basal cell carcinoma of the right lower lid margin. Management: typical management includes complete excision with histologically confirmed clear margins (margin-controlled techniques such as Mohs or slow-Mohs surgery where available), followed by lid reconstruction by an oculoplastic surgeon. The medial canthus — not involved here — is the danger zone, because tumours there can invade the lacrimal system and orbit silently. He is counselled on sun protection and skin surveillance, since one BCC predicts others.
Differential Diagnosis
- Chalazion — ruled out: no ulceration, no telangiectasia, no lash distortion; chalazia point inward and resolve.
- Squamous cell carcinoma — considered: biopsy distinguishes; SCC is less common on the lid and more aggressive.
- Sebaceous carcinoma — considered in older adults: can mimic BCC; histopathology decides.
Management
Typical management includes excision with margin control and histopathological confirmation, oculoplastic reconstruction of the lid margin, and dermatology/skin surveillance follow-up. Medial canthal lesions need wider assessment for deep invasion. The patient is advised on sun protection and to report any new non-healing lid lesion promptly.
Key Learning Points
- BCC: pearly nodule + telangiectasia + non-healing ulcer in a sun-exposed older adult.
- Lid-margin tumours need margin-controlled excision plus reconstruction — function matters as much as clearance.
- The medial canthus is the high-risk site for silent deep spread.
- One BCC means lifelong skin surveillance.
Red Flags
- A non-healing ulcerated lid nodule — biopsy; do not watch.
- Medial canthal location — risk of deep lacrimal and orbital invasion.
- Loss of lashes (madarosis) around a lid lesion — malignancy until proven otherwise.
