Insights
Congenital divided nevi are rare eyelid lesions. Surgical excision is effective for these benign melanocytic growths, preventing potential vision issues like amblyopia.
Area of Science:
- Ophthalmology
- Dermatology
- Pathology
Background:
- Congenital divided nevi are rare melanocytic lesions affecting the eyelids.
- Fewer than 30 cases have been documented in medical literature.
- This report details two new cases and reviews existing literature.
Observation:
- A 6-year-old boy presented with a nasally located, growing congenital divided nevus on the left upper and lower eyelids.
- A 41-year-old male had a laterally located congenital divided nevus on the left eyelid, present since birth and gradually increasing.
- Both patients had unremarkable ophthalmological examinations apart from the nevus.
Findings:
- Histopathological examination confirmed both lesions as melanocytic compound nevi.
- The 6-year-old's nevus was completely excised; the 41-year-old's nevus underwent subtotal excision with debulking and eyelid reconstruction.
- No malignant changes were observed in either case.
Implications:
- Congenital divided nevi can be disfiguring and may cause deprivation amblyopia in children if large.
- Surgical options include complete or subtotal excision with debulking.
- Early diagnosis and management are crucial to prevent visual impairment.
Background:
Congenital divided nevi of the eyelids are a rare melanocytic lesion. Only 30 patients are reported in literature. We report on a 6-year-old boy and a 41-year-old male with this lesion and give a short overview of the literature.
Case Reports:
Patient 1: A 6-year-old boy presented with a pigmented divided nevus of the left eye involving the upper and lower lid naselly. The lesion had increased in size in the last one year. Otherwise the results of ophthalmological examination were unremarkable. The divided nevus was completely excised. Histopathological studies revealed a melanocytic compound nevus. Patient 2: A 41-year old male presented in our department with a divided pigmented nevus on his left eye involving the upper and lower lid laterally. The lesion had gradually increased since birth. Otherwise the results of ophthalmological examination were unremarkable. A subtotoal excision and debulking procedure was performed. The defect in the lower eyelid was covered using a transposition flap from the upper eyelid. Histopathological examination revealed a melanocytic compound nevus.
Conclusion:
Divided nevi of the eyelids may be disfiguring and include the possibility of deprivation amblyopia when reaching a certain size in childhood. Malignant changes of this lesion were not observed so far. Total excision or subtotal excision and a debulking procedure may be helpful.
