Gastric adenocarcinoma associated with granulomatous gastritis. Case report and review of the literature.
AIMS: We describe the fourth reported case of granulomatous gastritis associated with gastric adenocarcinoma, with a review of the literature and considerations about the prognostic implications of this association. RESULTS: A 48-year-old woman who had been suffering from gastritis for ten years was admitted to our institute for increasing left epigastric pain associated with vomiting. After an endoscopic biopsy had revealed an ulcerated signet ring cell carcinoma, the patient was submitted to subtotal gastrectomy with regional lymph node dissection. Pathological examination of the resected specimen revealed a superficial signet ring cell carcinoma (early cancer) associated with multiple granulomas. The granulomas, which were observed within the mucosa and the submucosa at the periphery of the carcinoma, were composed of CD68-positive, CD15-negative epithelioid and giant cells of the Langhans type, confirming their true histiocytic nature, and were also extensively found within the dissected lymph nodes. Since no ocular, skin, pulmonary or other gastrointestinal lesions were found and the granulomas were negative for acid-fast and fungal stain, a diagnosis of granulomatous gastritis was made. CONCLUSIONS: To the best of our knowledge this is the fourth example of gastric adenocarcinoma and granulomatous gastritis. These cases suggest an association between granulomatous gastritis and early gastric cancer.

Cavernous hemangioma of the gallbladder. Case report and review of the literature.
UNLABELLED: Hemangiomas are common benign tumors; they frequently occur in the liver but very rarely in the gallbladder, with only seven cases reported in the scientific literature to date. We here report an additional patient, a 49-year-old white woman presenting with an echogenic lesion of the gallbladder that was incidentally discovered. Cholecystectomy was performed after computed tomography had revealed a gallbladder neoplasm; pathological examination showed the mass to be a cavernous hemangioma. No postoperative complications occurred and the patient is alive and free of recurrence five years after the operation. We present a review of the literature on this topic with special emphasis on the diagnostic and therapeutic challenges these lesions may entail. Hemangiomas of the gallbladder may have extremely variable presentations (from non-specific abdominal pain to acute syndromes resembling cholangitis or choledocholithiasis) and can mimic different lesions (liver tumors, sarcoma). Only surgical exploration can provide a correct diagnosis. Excision is indicated as these lesions may grow to huge sizes, compress adjacent structures or bleed. CONCLUSIONS: Gallbladder hemangiomas are uncommon benign tumors. A preoperative diagnosis is difficult to make. Surgical excision is mandatory both in reaching a final diagnosis and in preventing bleeding or compression of vital structures.
