The aim of the study was to determine the distribution of histologically diagnosed nonodontogenic cysts (nOCs) over a 40-year period in a Brazilian population. Biopsy records from patients with nOC from the files of the Oral Pathology Service during the period of 1970-2009 were evaluated. Among 10,311 oral biopsies, 58 met the criteria of nOCs. The most frequent nOCs were nasopalatine duct cysts (32.8%), followed by epidermoid cysts (20.7%) and oral lymphoepithelial cysts (17.2%). Nasopalatine duct cysts showed predominance among females (68.4%). Epidermoid cysts were most commonly found in the floor of the mouth (36.4%), tongue (27.3%), and buccal mucosa (27.3%). Oral lymphoepithelial cysts exhibited female prevalence (80.0%) and were commonly located in the tongue (44.4%). The frequency of nOCs found in the population studied here is slightly different from those reported in other case series. Nasopalatine duct cysts, epidermoid cysts, and oral lymphoepithelial cysts were the most common nOCs found, accounting for 70.7% of all nOCs.
本研究旨在确定巴西人群中组织学诊断的非牙源性囊肿（nOC）在 40 年期间的分布。评估了 1970 年至 2009 年期间口腔病理学服务档案中 nOC 患者的活检记录。在 10311 例口腔活检中，有 58 例符合 nOC 的标准。最常见的 nOC 是鼻腭管囊肿（32.8%），其次是表皮样囊肿（20.7%）和口腔淋巴上皮囊肿（17.2%）。鼻腭管囊肿在女性中占优势（68.4%）。表皮样囊肿最常见于口底（36.4%）、舌（27.3%）和颊粘膜（27.3%）。口腔淋巴上皮囊肿表现出女性优势（80.0%），常见于舌（44.4%）。本研究人群中发现的 nOC 频率与其他病例系列报道的略有不同。鼻腭管囊肿、表皮样囊肿和口腔淋巴上皮囊肿是最常见的 nOC，占所有 nOC 的 70.7%。
