Blisters in the pharynx and esophagus are well-documented, particularly in dystrophic EB (DEB). However, there have been few reports of mucocutaneous squamous cell carcinoma (SCC) in the head and neck region, for which surgery is usually avoided. This report presents the first case of free jejunal flap reconstruction after total pharyngolaryngoesophagectomy for hypopharyngeal cancer in a 57-year-old patient with DEB. The patient with a known diagnosis of DEB had a history of SCC of the left hand and esophageal dilatation for esophageal stricture. PET-CT imaging during examination of systemic metastases associated with the left-hand SCC revealed abnormal accumulation in the hypopharynx, which was confirmed as SCC by biopsy. Total pharyngolaryngoesophagectomy was performed, followed by reconstruction of the defect using a free jejunal flap. A segment of the jejunum, approximately 15 cm in length, was transplanted with multiple vascular pedicles. The patient made an uneventful recovery postoperatively and was able to continue oral intake 15 months later with no complications and no recurrence of SCC in the head and neck region. While cutaneous SCC is common in DEB, extracutaneous SCC is relatively rare. In most previous cases, non-surgical approaches with radiotherapy and chemotherapy were chosen due to skin fragility and multimorbidity. In the present case, vascular fragility and mucosal damage of the intestinal tract were not observed, and routine vascular and enteric anastomoses could be performed, with an uneventful postoperative course.

The procedure was successful, and no signs of lymphatic impairment were observed during the two-year follow-up period. We believe that this novel approach might be helpful in cases of large and profound defects that involve the deep lymphatic system.

Notably, anomalies in communicating branches were observed in 39 cadavers (83.0%): 14 with bilateral anomalies, 14 with anomalies on the left side, and 11 on the right side. These communicating branches formed connections between the roots and other segments, including trunks, cords, and terminal nerves, and involved the median, musculocutaneous, and ulnar nerves.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The frequency and diversity of brachial plexus variations, particularly in communicating branches, are significant in cadavers. It is imperative that these variations are carefully considered during the diagnostic process, treatment planning, and prior to procedures such as supraclavicular brachial plexus blocks and nerve transfers, to mitigate the risk of iatrogenic complications.</p>\u0000 </section>\u0000 </div>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/micr.31182","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141155428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
