    This study details a rare case of acquired canalicular cystocele, a tear duct cyst, caused by blockages in the inferior canaliculus. Histopathology showed a dilated tubule with specific epithelial lining and inflammatory cell infiltration.

    Area of Science:

    • Ophthalmology
    • Pathology

    Background:

    • Acquired canalicular cystocele is a rare condition affecting the tear drainage system.
    • Obstructions in the inferior canaliculus can lead to cyst formation.

    Observation:

    • A patient presented with symptoms related to an acquired canalicular cystocele.
    • The condition involved obstructions at both proximal and distal ends of the inferior canaliculus.

    Findings:

    • Histopathologic examination revealed a significantly dilated tubule (19 mm x 7 mm).
    • The tubule was lined with nonkeratinizing squamous epithelium.
    • The cyst wall was fibrotic and thickened, infiltrated by epithelioid, lymphoid, and plasma cells.
    • No mucous-secreting goblet cells were identified.

    Implications:

    • Understanding the histopathologic features is crucial for diagnosing and managing this rare condition.
    • The findings contribute to the literature on tear duct cyst pathologies.
    • Further research may explore the etiology and treatment strategies for acquired canalicular cystocele.
