Cysts of the incisive papilla are uncommon variants of the nasopalatine duct cysts. They may be symptomatic or asymptomatic and usually are not seen radiographically. This case report presents a flat, darkly pigmented asymptomatic lesion which required differentiation from a possible malignant melanoma. Due to its location in the anterior palate, this lesion is of interest and clinical significance to the periodontist.
切牙乳头囊肿是鼻腭管囊肿的罕见变异型。它们可能有症状或无症状，通常在影像学上不可见。本病例报告展示了一个扁平、色素沉着较深的无症状病变，需要与可能的恶性黑色素瘤相鉴别。由于其位于腭前部，该病变对牙周病医生具有研究价值和临床意义。
