摘要

我们报告一例54岁的患者被诊断为T1N0M0口腔鳞状细胞癌位于右侧上颌结节。治疗方案包括广泛的局部切除,部分上颌切除和前哨淋巴结活检。术前单光子发射计算机断层扫描/计算机断层扫描(SPECT/CT)显示淋巴引流至单个同侧咽后淋巴结(rouviires淋巴结/水平VIIa)。由于该淋巴结的手术可及性较差,我们决定不切除前哨淋巴结,继续进行肿瘤切除,重点评估肿瘤浸润深度,以评估转移风险。组织病理学分析证实边缘清晰,浸润深度为2mm。因此,病人被置于观察之下。本病例是首次报道的早期口腔鳞状细胞癌前哨淋巴结引流至rouvi淋巴结的病例,提出了独特的诊断和治疗挑战。

Early-stage oral cavity cancer (T1N0) with lymphatic drainage to the retropharyngeal lymph node: A therapeutic challenge
We report a case of a 54-year-old patient diagnosed with T1N0M0 oral squamous cell cancer located at the right maxillary tuberosity. The treatment plan included wide local excision with partial maxillectomy and sentinel lymph node biopsy. Preoperative single photon emission computed tomography/computed tomography (SPECT/CT) revealed lymphatic drainage to a single ipsilateral retropharyngeal lymph node (Rouvière's node/level VIIa). Due to the poor surgical accessibility of this lymph node, the decision was made to proceed with the tumor resection without sentinel lymph node excision, focusing instead on assessing the tumor's depth of infiltration to estimate the risk of metastasis. Histopathological analysis of the specimen confirmed clear margins with 2mm depth of infiltration. Consequently, the patient was placed under observation. This case represents the first reported instance of sentinel lymph node drainage to Rouvière's node in early oral squamous cell carcinoma, presenting a unique diagnostic and therapeutic challenge.
