Hand metastases occur infrequently, and metastatic tumors in the soft tissue of the hand caused by rectal cancer are extremely rare. We report a case here. The patient was a 76-year old man. He underwent Miles operation for rectal cancer located in the lower portion of the rectum. Histopathologically, the resected specimen showed well-differentiated adenocarcinoma. Six years postoperatively, a ...

BACKGROUND AND AIM Colon tumor carcinogenesis and rectal tumor carcinogenesis have each been associated with different genetic features, but data are still controversial and are insufficient to support their distinct molecular biology. Recently, genome-wide association studies (GWAS) have also found heterogeneity in colorectal cancer (CRC) risks based on population ethnicity and tumor features....

Heterotopic ossification in colorectal carcinoma is extremely rare. This report presents the case of a 57-year-old male who had undergone a low anterior resection following a diagnosis of rectal carcinoma. Histological examination showed heterotopic ossification in the tumor. The patient was referred to Ibaraki Medical Center, Tokyo Medical University, with a diagnosis of rectal carcinoma by a ...

A 71-year-old female presented to our hospital with recent increase in diarrhea and body weight loss. Radiologic and endoscopic examinations revealed rectal adenocarcinoma with synchronous multiple liver metastases accompanied by widespread intrabiliary tumor thrombi. After primary tumor resection, systemic treatment using 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX), 5-fluorouracil, le...

I n past years. the us" ,a1 surgical correction of rectal carci. noma was abdominal perineal resection with a permanent colostomy. This surgical procedure is very involved, requiring both abdominal and perineal wounds. The rectum is completely removed, leaving a large cavity to heal postoperatively, often with complications including slow healing and/or fistulization. Also, the patient must dea...

Controversy remains regarding whether preoperative chemoradiation protocol should be applied uniformly to all rectal cancer patients regardless of tumor height. This pooled analysis was designed to evaluate whether preoperative chemoradiation can be safely omitted in higher rectal cancer.An international consortium of 7 institutions was established. A review of the database that was collected f...

PURPOSE It is possible that implantation of viable malignant cells is one of the mechanisms of anastomotic recurrence in rectosigmoid cancer. The viability of shed intraluminal cells was previously established and malignant cells were retrieved on circular staplers in unwashed rectal stumps. The aim of this study is to evaluate the effectiveness of a defined and uniform washout protocol in erad...

A case of synchronous carcinoma of the accessory mammary gland and primary breast lymphoma with subsequent rectal carcinoma has not been reported previously. We present a very rare case of primary non-Hodgkin lymphoma of the left breast diagnosed simultaneously with invasive lobular carcinoma of the left axillary accessory mammary gland and rectal adenocarcinoma. An 82-year-old Japanese woman p...

BACKGROUND: Sphincter preservation, disease control, and long-term survival are the main goals in the treatment of rectal cancer. Although transanal local excision is attractive because it is a sphincter sparing procedure, some contradictory data exist in the literature about its ability to locally control disease and provide overall survival comparable with radical procedures, even for patient...

A 52-year-old man was referred to our institution with the presentation of rectal bleeding, and change in caliber of his stools. On rectal examination a solid mass was palpated in the prostate area. Transrectal needle biopsy and cytology showed a gastrointestinal stromal tumor. Subsequent rectal ultrasound demonstrated a hypoechogenic lesion that appeared to be growing out of the muscularis pro...
