Canaliculops or canaliculocele is a rare form of noninflammatory and noninfectious canalicular ectasia. To the best of the authors' knowledge, so far only 5 such cases have been described in the literature. Typical clinical and characteristic immunohistochemical features aid in the diagnosis. Although rare, it should be kept in the differential diagnosis of cystic lesions in the medial canthus area. The authors report the sixth such case, but the first case to show an association with punctal agenesis. Addition of more such cases to literature will help unravel the etiopathogenesis of this intriguing canalicular disorder.
