Bilateral Corneal Panni Associated with Limbal Inclusion Cysts in the Left Eye in a Patient with Atopic Keratoconjunctivitis.

Purpose: To report a rare case of atopic keratoconjunctivitis (AKC) presenting with bilateral corneal panni associated with limbal inclusion cysts in the left eye.

Materials & Methods: Retrospective case report.

Results: A 19-year-old female with AKC presented with bilateral corneal panni and limbal inclusion cysts in the left eye. Anterior segment swept-source optical coherence tomography showed bilateral hyperreflective epicorneal membrane and a lobulated cystic lesion in the left eye. Ultrasound biomicroscopy demonstrated a dense membrane overriding the cornea in both eyes and hyporeflective spaces separated by medium reflective septa in the cyst. The patient underwent excision of the limbal inclusion cyst and pannus in the left eye. Histopathological examination revealed subepithelial cystic lesion surrounded by non-keratinizing epithelium; areas of acanthosis, hyperkeratosis, parakeratosis, and hyperplasia in the epithelium of the pannus; as well as inflammation, fibrosis, and increase in vascularization in the stroma.

Conclusion: To our knowledge, this is the first case of corneal pannus associated with limbal inclusion cysts in AKC. Surgical excision was done to establish the diagnosis as well as to improve vision in our case.
