A histopathological survey of surgical materials from 143 patients with rectal carcinoma subjected to chemotherapy and low-dose radiotherapy with tegafur and bleomycin was carried out. The chemotherapy combined with radiotherapy brought about better results than chemotherapy alone. In 4 of the 58 patients treated with radiochemotherapy, no cancer cells could be found in surgical specimens. Exfo...
In Japan, lateral lymph node dissection (LLND) is generally performed for the treatment of T3-4 lower rectal carcinoma, and not for T1 lower rectal carcinoma, because of a low positive rate in patients with T1 lesion. We experienced a rare case of lateral pelvic lymph node recurrence after total mesorectal resection for T1 lower rectal carcinoma, successfully treated by LLND with en bloc resect...
Several factors determine overall outcome and possible local recurrence after curative surgery for rectal carcinoma. Surgical performance is usually believed to be the most pertinent factor, followed by adjuvant oncological treatment and tumor histopathology. However, chromosomal instability is common in colorectal cancer and tumor clones are assumed to differ in aggressiveness and potential of...
Verrucous carcinoma (VC) is a rare variant of well differentiated squamous cell carcinoma (SCC) which is usually found in oral cavity mucosa. Cutaneous verrucous carcinoma is a rare entity and in this paper we report a 43 years old man with VC superimposed on chronically inflamed skin of ileostomy site. Previously, he was operated to treat rectal adenocarcinoma and has had ileostomy for six mon...
Colorectal carcinoma is a common malignancy in India as well as in world. Inspite of its high metastasizing ability to various organs and lymph node, orbital metastasis is exceptional. Very few cases have been reported in the world literature. We report orbital metastasis in a case of moderately differentiated rectal adenocarcinoma in a 58-year male patient from India in 2015. We want to focus ...
Of 111 carcinomas developing in 73 patients with ulcerative colitis, 46 (41.5%) arose in the rectum where they are directly accessible to sigmoidoscopy. Fifty-eight per cent of single carcinomas developed in the rectum. The extent and frequency of rectal dysplasia was assessed by examining slides of rectal mucosa with an eyepiece micrometer. Slides from 46 patients with carcinoma and 22 patient...
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 ...
The rarity of rectal carcinoma in children has prompted us to report this patient who presented with bleeding per rectum and constipation. Histopathological examination of biopsy revealed the growth to be a colloid carcinoma of rectum and it was inoperable on exploratory laparotomy. There are three factors which contribute to an overall poor prognosis of rectal carcinoma in children viz. delay ...
