Punctal keratinizing cyst is an extremely rare ectasia arising from the most proximal part of the vertical canaliculus just beneath the punctum. To the best of the authors' knowledge, so far only 1 such case has been described in the literature. Typical clinical features and a meticulous histopathological examination aid in the diagnosis. Although rare, it should be kept in the differential diagnosis of punctal and peripunctal lesions. The authors report the second case with a few clinical and pathologic differences. Addition of more such cases to literature will help unravel the etiopathogenesis of this intriguing punctal disorder.
泪点角化囊肿是一种极其罕见的扩张性病变，起源于泪点下方垂直泪小管的最近端。据作者所知，迄今为止文献中仅描述过1例此类病例。典型的临床特征和细致的组织病理学检查有助于诊断。尽管罕见，但在泪点及泪点周围病变的鉴别诊断中应考虑到它。作者报告了第2例病例，该病例在临床和病理方面存在一些差异。文献中增加更多此类病例将有助于阐明这种有趣的泪点疾病的病因。
