Chronic unilateral blepharoconjunctivitis caused by sebaceous carcinoma

Area of Science:

• Ophthalmology
• Oncology
• Pathology

Background:

• Chronic unilateral conjunctivitis can present diagnostic challenges.
• Sebaceous carcinoma of the eyelid is a rare malignancy.
• Delayed diagnosis is common in sebaceous carcinoma cases.

Observation:

• A six-year history of chronic unilateral conjunctivitis masked an underlying sebaceous carcinoma.
• The case highlights the potential for misdiagnosis, even by experienced ophthalmic pathologists.
• Specific clinical suspicion is crucial for identifying eyelid malignancies.

Findings:

• The patient's chronic conjunctivitis was ultimately diagnosed as sebaceous carcinoma.
• This case underscores the importance of considering malignancy in persistent ocular inflammation.
• Pathologists require specific alerts to identify subtle malignant changes in eyelid biopsies.

Implications:

• Clinicians must maintain a high index of suspicion for sebaceous carcinoma in chronic conjunctivitis.
• Adequate surgical biopsies are essential for accurate diagnosis.
• Enhanced communication between clinicians and pathologists is vital for timely diagnosis of rare eyelid cancers.
