Abstract

Metastases in the oral and maxillofacial region, particularly in soft tissues, are exceedingly rare. Such metastases can present as swelling in older individuals, especially in the tongue and gingiva. Furthermore, colorectal metastases at this site are commonly found in the mandible and gingiva and usually share the same morphology as the primary tumor. Herein, we report the case of a 61-year-old woman with a metastatic nodule in the tongue covered by normal mucosa. The clinical, histopathological, and immunohistochemical findings were essential for the final diagnosis of colorectal metastasis, consistent with adenocarcinoma with mucinous differentiation and intestinal phenotype. Metastases of colorectal adenocarcinoma to the tongue are rare but should be included in the differential diagnosis of nodular lesions at this site. The diagnosis can therefore be made based on meticulous clinical and histopathological examination complemented by immunohistochemistry.

黏液性结直肠腺癌的舌头转移：罕见病例报告

口腔和颌面部的转移，尤其是软组织的转移，极为罕见。这种转移在老年人中可能表现为肿胀，尤其是在舌头和牙龈。此外，该部位的结直肠癌转移瘤常见于下颌骨和牙龈，通常与原发肿瘤形态相同。在此，我们报告了一例 61 岁女性的病例，她的舌头上有一个被正常粘膜覆盖的转移性结节。临床、组织病理学和免疫组化检查结果对最终诊断结直肠转移瘤至关重要，诊断结果与具有粘液分化和肠表型的腺癌一致。结直肠腺癌转移到舌头的情况很少见，但应将其纳入该部位结节性病变的鉴别诊断中。因此，可以根据细致的临床和组织病理学检查并辅以免疫组化来做出诊断。

期刊介绍： Head & Neck Pathology presents scholarly papers, reviews and symposia that cover the spectrum of human surgical pathology within the anatomic zones of the oral cavity, sinonasal tract, larynx, hypopharynx, salivary gland, ear and temporal bone, and neck. The journal publishes rapid developments in new diagnostic criteria, intraoperative consultation, immunohistochemical studies, molecular techniques, genetic analyses, diagnostic aids, experimental pathology, cytology, radiographic imaging, and application of uniform terminology to allow practitioners to continue to maintain and expand their knowledge in the subspecialty of head and neck pathology. Coverage of practical application to daily clinical practice is supported with proceedings and symposia from international societies and academies devoted to this field. Single-blind peer review The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
