概要

We report a case of a second free jejunal transfer to treat metastasis in the mesenteric lymph node of the first jejunal flap. A 73-year-old man underwent total pharyngolaryngectomy, bilateral neck dissection, and free jejunal transfer for recurrent hypopharyngeal cancer [left pyriform sinus, pT2N0, moderately differentiated squamous cell carcinoma (SCC)] after radiotherapy. Seven years post-surgery, he underwent transoral videolaryngoscopic surgery for oropharyngeal cancer (soft palate, pT1N0, well-differentiated SCC). Ten years after the first jejunal transfer, metastasis was found in the mesenteric lymph node surrounding the jejunal flap’s vascular pedicle. Under general anesthesia, resection of the first jejunum including the affected lymph node, and second jejunal transfer were performed. Lymph node pathological examination revealed poorly differentiated SCC, compatible with pharyngeal cancer metastasis. After neck dissection and jejunal flap transfer, lymphatic collateral pathways toward the flap’s mesenteric lymph node might form. Possibly, hypopharyngeal or oropharyngeal cancer metastasized via this pathway.

Figure 4. Pathological findings. (a) The specimen of hypopharyngeal cancer showed that dysmorphic cells with well-defined nucleoli were

proliferating without polarity, diagnosed as moderately differentiated SCC. (b) The specimen of oropharyngeal cancer was compatible with

well-differentiated SCC, which formed cancer pearls and papillary structures. (c) The mesenteric tumor of the first jejunum confirmed poorly

differentiated SCC, which consisted of dysplastic cells with rounded nuclei and distinct nucleoli.
