A 91-year-old man presented with an asymptomatic swelling in the roof of his mouth. Clinically the lesion was nontender and appeared cystic. A CT scan showed a soft tissue swelling of his palate with no bony involvement. An orthopantogram and blood tests were noncontributory. A fine-needle aspiration biopsy was suggestive of a minor salivary gland neoplasm. An excision biopsy showed papillary cystadenoma of the minor salivary gland, with numbers of psammoma bodies. A stepwise approach is demonstrated in the diagnosis of this rare minor salivary gland neoplasm. To the authors' best knowledge, this is the 12th case of this tumor seen in the palate. Furthermore, no previous case has included a fine-needle aspiration biopsy in the work-up, the cytological features of which will be described.
一名91岁男性因口腔顶部无症状肿胀就诊。临床上，该病变无压痛，呈囊性。CT扫描显示腭部软组织肿胀，无骨质受累。曲面体层摄影和血液检查无异常发现。细针穿刺活检提示为小唾液腺肿瘤。切除活检显示为小唾液腺乳头状囊腺瘤，伴有砂粒体。本文展示了诊断这种罕见小唾液腺肿瘤的逐步方法。据作者所知，这是腭部所见的该肿瘤第12例。此外，既往病例中均未在检查过程中进行细针穿刺活检，本文将描述其细胞学特征。
