ABSTRACT
Herein, we aimed to examine the diagnostic yield and utility of boring biopsy for subepithelial lesions (SEL) of the stomach and esophagus. A total of 52 patients with SELs of the stomach or esophagus underwent boring biopsy. The diagnostic yield of boring biopsy for gastric and esophageal SELs was 50% (21/42) and 80% (8/10), and for SELs with a diameter of less than 10mm, the diagnostic yield was 67% (6/9) and 83% (5/6), respectively. Forty-three percent (9/21) of the gastric SELs were diagnosed with gastrointestinal stromal tumor (GIST), while all esophageal SELs (8/8) were leiomyomas. Ten percent (4/42) of boring biopsies for the stomach were accompanied by complications:two cases of perforation and two of bleeding.

An 81-year-old woman with rectal mucinous carcinoma underwent a laparoscopic low anterior resection in February 2019, followed by chemotherapy using XELOX plus Bev. The adjuvant chemotherapy was discontinued due to interstitial pneumonia. During a follow-up consultation 2 years later, chest computed tomography(CT)imaging revealed a nodule in her right lung(S9). Based on a radiological diagnosis of metastasis and considering her history of rectal cancer, a partial resection of the right lung was executed. One year after the pulmonary resection, a growing nodule in her right lateral chest wall was detected. A metastatic chest wall tumor was suspected, and a right chest wall tumor resection at the 5th and 6th ribs was performed. A rectal mucinous carcinoma metastasis was diagnosed using histopathological examination. The postoperative course was good, and she was discharged from hospital on the 10th day. To conclude, there are few reported cases of rectal cancer chest wall metastasis, and a further accumulation of similar cases is necessary for the development of treatment options.
