4. Lymphoid follicular proctitis

Author

Fléjou, J. F., Potet, F., Bogomoletz, W. V., Rigaud, C., Fenzy, A., LE Quintrec, Y., Goldfain, D., and Brousse, N.

Abstract

A heterogeneous group is formed by patients presenting with clinical features suggestive of inflammatory bowel disease limited to the rectum and whose rectal biopsies show lymphoid follicular hyperplasia of the mucosa. All these cases are traditionally considered as one variant of chronic ulcerative colitis, so-called ulcerative proctitis. Twenty such cases were critically assessed on clinical, endoscopic, and histologic grounds, as well as on response to treatment and follow-up data. While 11 patients showed clinicopathologic features consistent with typical chronic ulcerative colitis, the other nine patients appeared to form a different group, for which the term “lymphoid follicular proctitis” seemed justified. Lymphoid follicular proctitis was, overall, characterized by rectal bleeding, a congested and granular mucosa without ulceration, abnormal and coalescing hyperplastic lymphoid follicle s without acute inflammation, and failure to respond to local steroid therapy. The nature of lymphoid follicular proctitis is uncertain at present but seems unrelated to chronic ulcerative colitis.

5. Fundic argyrophil carcinoid tumor in a patient with sporadic-type Zollinger-Ellison syndrome.

Abstract

In the Zollinger-Ellison syndrome, fundic argyrophil carcinoid tumors occur almost exclusively in the small subgroup of patients who also have multiple endocrine neoplasia type 1. In these patients, tumor development seems related to the same genetic alterations as those observed in other endocrine tumors related to multiple endocrine neoplasia type 1. We report here the second detailed case of a patient with sporadic Zollinger-Ellison syndrome who developed an argyrophil carcinoid tumor in nonatrophic fundic mucosa, suggesting that chronic hypergastrinemia may lead to fundic carcinoid development in nongenetically predisposed patients.

6. Regression of inflammatory pseudotumor of the liver under conservative therapy.

Abstract

Inflammatory pseudotumors (IPT) of the liver are rare benign tumors of unknown origin. Most previously reported cases were initially misdiagnosed and treated surgically; thus, their course under medical treatment remains unclear. We report an additional case of hepatic IPT with a favorable outcome under medical treatment without surgical resection. New imaging and pathologic features of this disease are presented that may facilitate preoperative recognition and appropriate treatment.
