OBJECTIVE To scrutinize all colonic biopsies and document the prevalence and pattern of various colonic diseases amongst the patients presenting at a tertiary care hospital of Western Saudi Arabia. METHODS We examined the record of all colonic biopsies, processed at Histopathology Department of King Abdul Aziz University Hospital; Jeddah from January 2002 to July 2007. RESULTS The colonic b...

A 59-year-old female with dysphagia presented to our clinic. In childhood, she underwent colonic interposition due to anastomotic stricture after a previous proximal gastrectomy for gastric ulcer perforation. Imaging studies revealed a space-occupying lesion obstructing the distal interposed colon. At surgery, completion gastrectomy with segmental colectomy was carried out, and Roux-en-Y coloen...

We report a case of synchronous primary colonic adenocarcinoma and malignant mesothelioma. A 61-year-old male presented with a six-month history of fatigue and weight loss. An abdominal computed tomography (CT) scan showed a 5.8 cm partially obstructing mass in the cecum with ascites and peritoneal thickening. A biopsy of the large mass showed an adenocarcinoma. Because the patient was clinical...

A 68-year-old previously healthy man presented with increasing right hip pain of 6 months duration. On examination he was found to have a hard mass in the right hip arising from the pelvic bone. Imaging studies were in keeping with a sarcoma arising from the right iliac bone. However, biopsy of this bony lesion confirmed this to be a metastatic adenocarcinoma rather than a primary bone malignan...

Colonic adenocarcinoma revealed by metastatic anorectal fistula is rare, with few cases in the literature. Such lesions can be taken for the more common manifestation of a benign perianal abscess or fistula. Once diagnosed, the management of such conditions remains controversial. We herein report two cases with perianal fistula that were subsequently found to have developed perianal adenocarcin...

Peutz-Jeghers syndrome (PJS) is an hereditary syndrome characterized by gastrointestinal polyposis and mucocutaneous pigmentation. PJS patients are at increased risk of developing various cancers, especially of the gastrointestinal and gynaecological tracts. Colonic adenocarcinoma is one of the more common tumours that occur in PJS. We report a young lady presenting with a large ovarian tumour,...

Metastasis to the primary thyroid carcinoma is extremely rare. We report here a case of colonic adenocarcinoma metastasis to medullary thyroid carcinoma in a 53-yr old man with a history of colon cancer. He showed a nodular lesion, suggesting malignancy in the thyroid gland, in a follow-up examination after colon cancer surgery. Fine needle aspiration biopsy (FNAB) of the thyroid gland showed t...

Colon interposition is an established technique for esophageal reconstruction. We describe the case of primary adenocarcinoma arising in a colonic interposition graft that was performed after total esophagectomy for recurrence adenocarcinoma derived from the Barrett esophagus.
