Metastasis to the gallbladder from other malignancies is extremely rare and is related with a very poor prognosis. Malignant melanoma has been reported to be the most common origin of gallbladder metastasis. Although only eight cases of gallbladder metastasis originating from gastric cancer have been documented in the literature based on small series, of these cases, only one case with signet ring cell carcinoma histology has been reported previously. We report the case of a 58-year-old male with early-stage signet ring cell carcinoma of the stomach who presented with acute cholecystitis previously treated with curative gastrectomy. After laparoscopic cholecystectomy, the diagnosis of gallbladder metastasis with signet ring cell histology secondary to gastric cancer was made. To our knowledge, this is only the second case of signet ring cell carcinoma of the stomach metastasized to the gallbladder as a first site of recurrence. We suggest that for patients with gastric cancer who complain of the findings of acute cholecystitis or cholecystolithiasis, gallbladder metastasis from gastric cancer should be considered in the differential diagnosis.
