摘要

这个病例报告描述了一个41岁的男性，在肛周区域有一个逐渐增大的、疼痛的植物性病变，最终通过穿孔活检诊断为鳞状细胞癌（SCC）。利用99mtc -植酸盐通过术前淋巴显像进行前哨淋巴结（SLN）定位。值得注意的是，在髂前上棘（ASIS）下皮下组织的非典型位置发现了SLN，与肛周鳞状细胞癌的典型引流模式不同。手术切除sln未发现肿瘤累及的证据。本病例强调了非典型淋巴引流模式术前淋巴显像个性化评估的重要性，以有效分期和治疗恶性肿瘤，如肛周淋巴细胞癌。

Lymphoscintigraphy for Peri-Anal Squamous Cell Carcinoma: A Case Report of an Atypical Location for Sentinel Lymph Node.

This case report describes a 41-year-old man with a progressively enlarging, painful vegetative lesion in the perianal region, ultimately diagnosed as squamous cell carcinoma (SCC), through a punch biopsy. Sentinel lymph node (SLN) mapping was performed via preoperative lymphoscintigraphy utilizing 99m Tc-Phytate. Notably, an SLN was identified in an atypical location, below the anterior superior iliac spine (ASIS) in the subcutaneous tissue, diverging from typical drainage patterns associated with perianal SCC. Surgical excision of the SLNs revealed no evidence of tumoral involvement. This case underscores the importance of personalized assessment with preoperative lymphoscintigraphy in atypical lymphatic drainage patterns for effective staging and treatment of malignancies such as peri-anal SCC.
