OBJECTIVE
Canalicular adenoma (CA) is an uncommon but unique benign tumor of salivary gland origin. It is the third most common benign tumor of minor salivary glands, representing less than 1% of all salivary neoplasms. A systematic review is presented of reported cases of CA, to determine trends in presentation, diagnostic features, treatment, and patient outcome.
METHODS
Searches of specific databases, as reported, were carried out to identify papers reporting CA. The variables were patient symptoms, tumor location, histopathological findings, demographics, treatment, follow-up, and recurrence.
RESULTS
430 cases were identified; the most common location was in the upper lip (66.3%), followed by hard palate (14.5%). The most common clinical presentation was a nodule (46.5%), followed by asymptomatic (29.5%), and discomfort (28.7%). CA was most frequently seen in females (64%). The average age was 66.3 years. 97% of cases were treated surgically. The average follow-up was 136.3 months, and recurrence was reported in 3% of the cases.
CONCLUSION
CA shows a strong predilection for the upper lip. CAs are frequently asymptomatic, but the principal symptom was pressure.
目的
泪小管腺瘤（CA）是一种罕见但独特的唾液腺来源良性肿瘤。它是第三大常见的小唾液腺良性肿瘤，占所有唾液腺肿瘤的不到 1%。本文对已报道的 CA 病例进行了系统回顾，以确定其表现、诊断特征、治疗和患者预后的趋势。
方法
按照报道，对特定数据库进行了搜索，以确定报告 CA 的论文。研究的变量包括患者症状、肿瘤位置、组织病理学发现、人口统计学、治疗、随访和复发。
结果
共确定了 430 例病例；最常见的部位是上唇（66.3%），其次是硬腭（14.5%）。最常见的临床表现是结节（46.5%），其次是无症状（29.5%）和不适（28.7%）。CA 多见于女性（64%）。平均年龄为 66.3 岁。97%的病例接受了手术治疗。平均随访时间为 136.3 个月，3%的病例报告复发。
结论
CA 对上唇有强烈的偏好。CA 通常无症状，但主要症状是压迫感。
