Intravenous leiomyoblastoma.

A unique case of leiomyoblastoma involving the veins and venules of the skin and subcutaneous space is reported. There was no evidence of recurrence or metastasis 1 1/2 years after excision.

Barrett's metaplasia and dysplasia in postmyotomy achalasia patients.

Three patients who were 8 to 30 years status postmyotomy for achalasia were shown to develop Barrett's columnar metaplasia of the esophagus. In one instance, the patient had multiple areas of severe dysplasia to carcinoma in situ. There have been only a few reports in the world literature of Barrett's metaplasia occurring in postmyotomy achalasia patients. Our experience would indicate it may be a more common complication than previously appreciated. Also, a possible causal relationship between surgical intervention, Barrett's epithelium, and adenocarcinoma in achalasia is suggested.

Primary tracheal neurilemoma: report of a case with ultrastructural examination.

A case of tracheal neurilemoma that was removed by segmental tracheal resection was studied. Only seven other cases of benign neurogenic tracheal tumor (three neurofibromas and four neurilemomas) were found in the literature. Failure to consider this rare tracheal tumor as a cause of respiratory distress has frequently resulted in delay of its recognition.

Benign mixed tumor of the trachea.

A case of mixed tumor, salivary gland type, removed by segmental resection of the trachea is reported. Only thirteen acceptable and five probable tracheal mixed tumors have been found in the world literature. The behavior of this variety of tumor in the trachea appears to be similar to its counterpart in other sites and distinctly different from the more frequently encountered epithelial tumors: squamous cell carcinoma and adenoid cystic carcinoma.

Symptoms, gastritis, and Helicobacter pylori in patients referred for endoscopy.

Acute Helicobacter pylori infection is associated with dyspeptic symptoms but chronic infection has not clearly been shown to cause symptoms. To define further the role of H. pylori infection and gastritis in dyspepsia, we interviewed all patients about to undergo upper endoscopy, recorded the primary indication for endoscopy, noted the endoscopic findings, and obtained antral biopsies. Among non-ulcer patients there was a strong correlation of acute gastritis with H. pylori. Gastritis and H. pylori increased with age, and non-steroidal anti-inflammatory drug use correlated with normal histology. Neither H. pylori concentration nor gastritis grade correlated with gender, use of alcohol and tobacco, indication for endoscopy, or symptoms (epigastric pain, nausea, vomiting, bloating, belching, heartburn, halitosis, and flatulence).
