Carcinoma cuniculatum, a well-differentiated squamous cell carcinoma, is a rare neoplasm with a low risk of metastasis.
A 74-year-old female patient is presented with a carcinoma cuniculatum of the right maxilla, a very rare variant of squamous cell carcinoma that usually occurs in the skin of the lower extremities, in particular, in the skin of the plantar surface of foot. It is described by an invasive growth pattern, but metastases to regional lymph nodes are rare. In the oral cavity, only very few cases have been published.
The correct diagnosis of this entity with the knowledge that it is a variant of a low-grade carcinoma with low risk of metastasis is important, so that elective neck dissection must not be obligate.
腺样囊性癌是一种高分化鳞状细胞癌，是一种罕见的肿瘤，转移风险低。
本文报道一名74岁女性患者，患有右上颌腺样囊性癌，这是一种非常罕见的鳞状细胞癌变体，通常发生于下肢皮肤，尤其是足底皮肤。它以浸润性生长模式为特征，但区域淋巴结转移罕见。在口腔中，仅有极少数病例被报道。
正确诊断该实体，并了解其为低转移风险的低级别癌变体非常重要，这样选择性颈部清扫并非必须。
