RESUMO

BACKGROUND: The occurrence of sarcoid reactions has been recognized in various cancers. The common location for observing these granulomas is mainly the lymph nodes, but a rare occurrence in the spleen has been reported. Almost all splenic sarcoid reactions associated with gastric cancer have been resected synchronously and diagnosed accidentally, and a rare metachronous occurrence of a sarcoid reaction in the spleen after distal gastrectomy can mimic cancer metastasis. We describe a rare case of a splenic sarcoid reaction recognized in a patient with gastric cancer 6 months after distal gastrectomy. CASE PRESENTATION: An 82-year-old man underwent laparoscopic distal gastrectomy for gastric cancer (T3N0M0, stage IIA). Six months after gastrectomy, CT and 18F-fluorodeoxyglucose (FDG)-PET/CT showed the appearance of a splenic mass. We diagnosed solitary splenic metastasis from gastric cancer and performed laparoscopic-assisted splenectomy. His splenic tumor was diagnosed as a sarcoid reaction by histopathological examination. CONCLUSION: To our knowledge, this is the first report of a splenic sarcoid reaction recognized 6 months after distal gastrectomy for gastric cancer without any chemotherapy. The splenic sarcoid reaction and cancer metastasis to the spleen were undistinguishable from the CT and FDG-PET/CT findings. The present case and literature review showed that cases of splenic sarcoid reactions associated with gastric cancer can also be accompanied by the occurrence of these granulomas in lymph nodes. When the appearance of a solitary mass is observed in the spleen after resection of primary cancer, it is necessary to consider not only cancer metastasis but also sarcoid reactions. Retrospective histopathological confirmation of the existence of sarcoid reactions in lymph nodes from resected specimens might possibly avoid incorrect diagnosis and intervention.

RESUMO

BACKGROUND: Median arcuate ligament syndrome (MALS) is a rare clinical entity caused mainly by extrinsic compression of the celiac axis by the median arcuate ligament (MAL). Severe celiac artery stenosis can lead to the development of collateral circulation, aneurysms, and, rarely, superior mesenteric artery (SMA) dissection. The treatment of MALS involves the surgical release of the MAL. However, a standard procedure with the use of laparoscopy has not been established, and intraoperative complications can lead to severe vascular injury. CASE PRESENTATION: The patient was a 43-year-old man with MALS identified at the onset of SMA dissection. After treatment for the SMA dissection, he underwent laparoscopic MAL release. Using the technique of laparoscopic gastrectomy within the surgical field, we performed laparoscopic MAL release and ganglionectomy safely with a good view. Immediate symptomatic improvement was acquired, and no recurrence was observed at the 20-month follow-up. CONCLUSION: We reported a rare case of MALS and SMA dissection. A horizontal 3D laparoscopic approach of the celiac axis allows for safe, meticulous, and radical MAL release and ganglionectomy.
