Orbital dermoid cyst with sinus tract mimicking ectopic cilia

Area of Science:

• Ophthalmology
• Pediatric Surgery
• Dermatology

Background:

• Periorbital masses are common in pediatric patients.
• Dermoid cysts represent the most frequent type of these masses.
• Ectopic cilia are hairs growing abnormally from the eyelid margin.

Observation:

• An unusual case of a pediatric patient with a dermoid cyst on the upper eyelid was observed.
• The cyst presented with a sinus tract from which black hairs emerged.
• This clinical presentation mimicked the appearance of ectopic cilia.

Findings:

• The case highlights an atypical presentation of a dermoid cyst.
• The presence of hairs from a sinus tract is a rare finding.
• Radiologic examination proved valuable in diagnosing the condition.

Implications:

• This case underscores the importance of considering dermoid cysts in the differential diagnosis of periorbital masses with unusual features.
• It emphasizes the diagnostic utility of imaging modalities, such as MRI or CT scans, in characterizing orbital lesions.
• Accurate diagnosis is crucial for appropriate management and to prevent potential complications.
