Gastric pseudolymphoma. A challenging clinical problem.
Gastric pseudolymphoma is a benign inflammatory condition that is usually associated with chronic gastric ulcer and often mimics gastric carcinoma or malignant lymphoma. Our experience with 12 histologically documented gastric pseudolymphomas at the Medical College of Virginia is presented with an emphasis on the approach to both diagnosis and surgical management. Preoperative diagnoses in this series ranged from benign gastric ulcer to gastric cancer. Treatment was by gastric resection in all cases and it included, as a minimum, antrectomy and excision of the lesion with an adequate gross margin. Of 11 cases with adequate follow-up, there are eight asymptomatic patients without recurrence and one patient who died of other causes without recurrence 5 years after gastrectomy. One patient developed recurrent pseudolymphoma in the proximal gastric remnant 39 months after a distal subtotal gastrectomy for pseudolymphoma. Another patient subsequently developed Hodgkin's disease of the gastric remnant, with regional lymph node and liver involvement, and died 35 months after the earlier subtotal gastrectomy for pseudolymphoma. Our clinical experience with this confusing and uncommon entity is compared with that previously reported in the medical literature.
