Abstract Background: Among early colorectal cancers, pedunculated polyps have a higher complete resection rate than non-pedunculated cases and rarely require additional surgery. However, this time, we experienced a case of pedunculated colorectal cancer, which was histologically poorly differentiated adenocarcinoma. Lymphatic invasion was also found, so additional intestinal resection was performed and nodal metastasis was found.Case presentation: A 43-year-old woman underwent colonoscopy because of positive fecal occult blood. A 20 mm-sized pedunculated polyp was found in the descending colon, and endoscopic resection was performed. Histopathological examination revealed non-solid poorly differentiated adenocarcinoma, invading to the submucosa (3,500 μm from the muscularis mucosae) with lymphatic invasion. In spite of its early stage cancer, the risk of nodal metastasis was considered to be high, and bowel resection was additionally performed. Although there was no residual cancer in the site after endoscopic resection, a metastasis was found in one regional lymph node. The patient is undergoing postoperative adjuvant chemotherapy. There was no evidence of recurrence after three months after the additional surgery. Conclusions:　 For pedunculated polyps, additional bowel resection was performed for patients with multiple risk factors for nodal metastasis such as poorly differentiated adenocarcinoma and positive lymphatic invasion. Then, we experienced a case of nodal metastasis, so we report it with a review of the literature.

Abstract Background Pedunculated polyps are more likely to be amenable to complete resection than non-pedunculated early colorectal cancers and rarely require additional surgery. We encountered a patient with a pedunculated early colorectal cancer that consisted of poorly differentiated adenocarcinoma with lymphatic invasion. We performed an additional bowel resection and found nodal metastasis. Case presentation A 43-year-old woman underwent colonoscopy after a positive fecal occult blood test. The colonoscopist found a 20-mm pedunculated polyp in the descending colon and performed endoscopic resection. Histopathologic examination revealed non-solid type poorly differentiated adenocarcinoma. The lesion invaded the submucosa (3500 μm from the muscularis mucosa) and demonstrated lymphatic invasion. In spite of the early stage of this cancer, the patient was considered at high risk for nodal metastasis. She was referred to our institution, where she underwent bowel resection. Although there was no residual cancer after her endoscopic resection, a metastatic lesion was found in one regional lymph node. The patient is undergoing postoperative adjuvant chemotherapy, and there has been no evidence of recurrence 3 months after the second surgery. Conclusions Additional bowel resection is indicated for patients with pedunculated polyps and multiple risk factors for nodal metastasis, such as poorly differentiated adenocarcinoma and lymphatic invasion. We encountered just such a patient who did have a nodal metastasis; herein, we report her case history with a review of the literature.

Metastatic tumours of the hand are uncommon. The majority of these tumours affect the phalanges and the primary tumours are usually bronchogenic in origin, with breast and kidney tumours next in frequency. Metastatic gastrointestinal to the hand is rare and usually from the colon. We report a case of poorly differentiated adenocarcinoma of the stomach antrum presenting with a metastatic lesion to the right 4th metacarpal bone. A review of the literature is included.
