Benign gastric lymphomatosis (gastric pseudolymphoma).

The present paper reports on two cases of gastric lymphomatosis whose diagnosis could only be established by histologic examination of the operative specimen. Benign gastric lymphomatosis (BGL) is characterized by lymphoid infiltration of the gastric wall, predominant in the mucosa and sometimes in the submucosa, running a slow benign course. It must be differentiated from malignant gastric lymphomas and from inflammatory lymphoid reactions surrounding ulcers. BGL have not been treated medically to date. One of the patients initially underwent an eight months treatment with prednisone, then with prednisone and cytostatics, which resulted in clinical improvement but did not modify the pathohistologic picture. As BGL represents a precancerous state and cannot be controlled at present by any medical treatment, the surgical intervention is considered opportune.

Fatal intestinal hemorrhage complicating ileal lymphoma after cyclosporine for unresponsive celiac disease.

BACKGROUND/AIMS: Unresponsive celiac disease may benefit from immunosuppressive therapy. Malignant small intestinal lymphoma is the most serious complication of celiac disease, also being noted as a complication of immunosuppressive therapy. The diagnosis of small intestinal lymphoma complicating celiac disease is notoriously difficult. Perforation is the most common complication of small intestinal lymphoma, frank hemorrhage being unusual. We report a case of massive, fatal hemorrhage from small intestinal lymphoma complicating unresponsive celiac disease treated with cyclosporine. The patient was presented with severe diarrhea and nutritional deterioration. Unresponsive celiac disease was diagnosed on the basis of clinical and histologic criteria with no response while on a gluten-free diet, corticotherapy and octreotide acetate injections. Cyclosporine therapy was advised. The patient had a remarkable clinical response. After 3 months from the start of the cyclosporine therapy, the patient returned with massive intestinal bleeding. The patient underwent emergency surgery diagnosing an enteropathy-associated lymphoma. We conclude that cyclosporine therapy for unresponsive celiac disease should be considered in select, severely ill patients only after a full-thickness biopsy of the small intestinal wall to disclose a latent super-imposed lymphoma, which course may be accelerated by immunosuppressive therapy.

Esophageal tumor with an unusual histological appearance: a case report.

An unusual esophageal tumor in a 58-year-old man complaining of dysphagia and weight loss is herein described. Esophageal radioscopy and endoscopy visualized a huge polypoid tumor which was occluding the esophagus. After esophageal resection, the histological examination revealed miscellaneous benign cells (squamous, columnar fat cells, cartilaginous cells, and glandular structures) and two different malignant areas (spindler sarcomatous cells and squamous cells). There was no malignant invasion in the stalk, in the adjacent esophageal wall, or in the periesophageal tissue, and there were no malignant adenopathies. The postoperative course was favorable for one year, until the patient developed pain in the right superior back. A sarcomatous relapse was diagnosed by fine-needle biopsy under CT guidance, and the patient subsequently received radiation therapy.

Long esophageal stricture in Crohn's disease: a case report.

Crohn's disease of the esophagus is rare, and it is very unusual for it to be located only in the esophagus. We report a case of Crohn's disease confined to the esophagus in a 26-year-old female. The patient was admitted because of progressive dysphagia, odynophagia and weight loss. A barium-swallow examination showed an irregular narrowing of the esophagus below the level of the aortic arch which was 15 cm long, with marginal ulcers and a pseudopolypoid appearance of the mucosa; a computed tomographic scan of the thorax revealed a thickened esophageal wall. Esophagoscopy revealed an esophageal stricture 25 cm distal to the incisor teeth, 2 mm in diameter, with "punched out" ulcers and pseudopolypoid mucosa. Endobiopsy specimens showed chronic lymphocytic infiltration into the corion in the absence of neutrophils, basal-cell hyperplasia and elongation of the stromal papillae. The patient underwent an esophagectomy through a combined cervico-abdominal approach followed by a cervical esogastrostomy. The specimen was 18 cm long, the thickness of the wall was 1.7 cm with fibrosis involving all layers of the esophageal wall and a cobblestone appearance of the mucosa. A heavy lymphoplasmocytic infiltrate extended from the mucosa deep into the muscularis, fibrosis and granulomas were found transmurally. Crohn's disease of the esophagus is a rare and specific entity which can present in various ways; strictures resembling those from reflux esophagitis or a tumor are common. Diagnosis may be suggested by the presence of a chronic lymphocytic infiltrate with or without non-caseating granulomas, and no histologic evidence of chronic reflux esophagitis.
