Intrahepatic cholangiocarcinoma: report of a surgically resected case.

We report a middle aged female with intrahepatic cholangiocarcinoma which was resected successfully. Because of an unusual histology, a microscopic diagnosis could not be established pre-operatively. The tumor recurred locally 21 months after surgery. The case is reported mainly for the diagnostic problems it created.

Solitary rectal ulcer syndrome and colitis cystica profunda--a clinico-pathological review.

Twenty cases of solitary rectal ulcer syndrome (SRUS) and three cases of colitis cystica profunda (CCP) diagnosed between 1985 to 1990 were studied retrospectively. Clinical features, sigmoidoscopic findings and histopathology of the above lesions were reviewed. Haematoxylin and Eosin, Masson's Trichome, and high iron diamine Alcian blue staining was done in all the cases. Histopathologic examination helps in diagnosing the benign condition of the rectum viz. SRUS and CCP which are considered malignant clinically. Since an overlap of histopathological features were seen in SRUS and CCP, both can be considered as one entity, which has been highlighted in our study. Fibromuscular obliteration of lamina propria is the hallmark of the lesion.

Adaptative changes in terminal ileum after total colectomy, mucosal proctectomy and straight ileo-anal anastomosis in chronic ulcerative colitis.

Total colectomy, mucosal proctectomy and straight ileo-anal anastomosis was performed in four adult patients with chronic ulcerative colitis (three males, one female; mean age 27.4 years). During a follow-up period of one to five years, all patients were continent, had spontaneous bowel evacuation (average 4-5 per day), and had normal bladder and sexual function. Sequential per rectal ileoscopies revealed loss of ileal folds and gradual transformation to a colonic type of mucosa. On barium studies, the anastomosed terminal ileum showed progressive ballooning and assumed a rectosigmoid appearance with complete disappearance of ileal characteristics. The histology showed a progressive transformation from ileal to colonic type of mucosa, with blunting and ultimate disappearance of villi, increasing goblet cell population, and increase in mononuclear cells in the lamina propria. Histochemical studies (high iron diamine and alcian blue stains) revealed a change from small intestinal to colonic mucin, progressing proximally from just above the anastomotic site. Two patients had a single recurrence with ileal histology resembling that of active ulcerative colitis; both responded to short term steroid therapy. The results of straight ileo-anal anastomosis compare well with Western reports of ileal reservoirs. Adaptative changes of 'colonisation' can be consistently demonstrated in the anastomosed ileum on follow-up; these start just above the anastomotic site and ascend proximally. The colonised ileum appears to be susceptible to the ulcerative disease.
