Canalicular cystocele.
We report a rare case of acquired canalicular cystocele in a patient with obstructions at both the proximal and distal ends of the inferior canaliculus. Histopathologic examination revealed a dilated tubule lined with nonkeratinizing squamous epithelium that measured 19 mm long and 7 mm wide. No mucous secreting goblet cells were observed in any sections. The fibrotic, thickened wall was infiltrated with epithelioid, lymphoid, and occasional plasma cells.
