Abstract

Background/Aim: Squamous cell carcinoma (SCC) is the most frequent carcinoma when dealing with malignant tumors of the oral cavity. SCC of the head and neck show cervical lymphatic metastasis, which is the most important prognostic factor for the long-term outcome of these patients. Hematogenous spread of this entity is rare, especially distant osseous metastasis. Therefore, the therapy for SCC typically consists of surgical tumor resection, neck dissection and plastic reconstruction. Most recurrences occur within the first two years postoperatively. This results in the need for close tumor follow-up.

Case report

The present case report describes a 79-year-old female suffering from a recurrent SCC of the oral cavity 19 years postoperatively firstly noticed through symptomatic osseous metastasis of the right femur. Trial excision of the right femur revealed the finding of a metastatic squamous cell carcinoma. The patient received palliative radiation therapy.

Conclusion

Osseous metastasis of SCC to the femur is rare. What is remarkable about this case report is the time span of 19 years between primary curative treatment, unremarkable follow up and the presence of metastatic late recurrence. Therefore long-term close follow-up in the treatment of oral cavity SCC in an interdisciplinary context is crucial.

晚期复发性口腔鳞状细胞癌罕见的股部转移

背景/目的：鳞状细胞癌（SCC）是口腔恶性肿瘤中最常见的恶性肿瘤。头颈部SCC显示颈淋巴结转移，这是影响这些患者长期预后的最重要的预后因素。这种实体的血行扩散是罕见的，尤其是远处的骨转移。因此，SCC的治疗通常包括手术切除肿瘤、颈清扫和整形重建。大多数复发发生在术后的头两年内。这导致需要对肿瘤进行密切随访。病例报告本病例报告描述了一名79岁的女性，术后19年复发性口腔鳞状细胞癌，首次通过右股骨的症状性骨转移引起。右股骨切除试验显示发现一个转移性鳞状细胞癌。病人接受了姑息性放射治疗。结论骨鳞状细胞癌骨转移到股骨是罕见的。该病例报告值得注意的是，从最初的治疗、不明显的随访到晚期转移复发之间的时间跨度为19年。因此，在跨学科背景下对口腔SCC的治疗进行长期密切随访是至关重要的。

期刊介绍： Oral and Maxillofacial Surgery Cases is a surgical journal dedicated to publishing case reports and case series only which must be original, educational, rare conditions or findings, or clinically interesting to an international audience of surgeons and clinicians. Case series can be prospective or retrospective and examine the outcomes of management or mechanisms in more than one patient. Case reports may include new or modified methodology and treatment, uncommon findings, and mechanisms. All case reports and case series will be peer reviewed for acceptance for publication in the Journal.
