Signet-ring cell variant is a rare type of adenocarcinoma that has been reported in the paranasal sinuses and in other areas, most commonly the gastrointestinal tract. We describe a patient with signet-ring cell adenocarcinoma of the maxillary sinus who had dental and facial pain. Further evaluation revealed that the lesion was metastatic from an esophageal primary lesion. The unusual nature of this cell type and the importance of careful evaluation to exclude the possibility of these lesions representing metastatic lesions is discussed.
印戒细胞变异型是一种罕见的腺癌类型，已在鼻窦及其他部位有报道，最常见于胃肠道。我们描述了一名患有上颌窦印戒细胞腺癌且伴有牙齿和面部疼痛的患者。进一步评估发现该病变是由食管原发性病变转移而来。本文讨论了这种细胞类型的特殊性以及仔细评估以排除这些病变为转移性病变可能性的重要性。
