Diffuse neurofibroma of the pylorus: a cause of gastric outlet obstruction.

We describe a benign diffuse neurofibroma of the pylorus, unassociated with von Recklinghausen's neurofibromatosis, which was a cause of pyloric stenosis; epigastric discomfort, vomiting, and weight loss of 60 lb were the most prominent symptoms. Partial gastrectomy resulted in a cure. The literature on nerve-sheath tumors of the stomach is reviewed.

Lymphomatoid granulomatosis. Report of a patient with severe anemia and clubbing.

We report a 31-year-old man in whom initially localized lymphomatoid granulomatosis was diagnosed at left pneumonectomy. He had severe anemia which is rare and clubbing of the fingers and toes, a feature not previously described. Five months following surgery, disease spread to the right lung, and atypical lymphomatous transformation occurred in cervical and mediastinal lymph nodes, leading to a superior vena cava syndrome.
