“…3 The fi rst case of heterotopic gastric mucosa in the gallbladder was described in 1934 by Egyedi. 4 In Japan, 25 cases have so far been reported, including that in the present patients since the fi rst case reported by Tomita in 1977, [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] while 51 cases of heterotopic gastric mucosa in the gallbladder had been reported in other countries up to 2007. 1,3,[21][22][23][24][25][26][27][28][29] In the 72 detailed case reports (including our own), the sex distribution is roughly equal (40 males, 32 females).…”

“…Intraoperative frozen examinations therefore seem to be indispensable to rule out the presence of gallbladder carcinoma. However, this examination was performed in only 8 cases, including those in this report, 7,9,13,17,19,21 and a correct diagnosis was made only in 2 cases, including our Case 2. 7 However, care must be taken as we did in our Case 1.…”

“…Seventeen cases presented with an echogenic polypoid lesion in the gallbladder as in our two cases, 1,6,9,10,15,[17][18][19][20]24,26,28 whereas a low echogenic polypoid lesion was diagnosed in three cases. 3,11,13 In addition, one case presented with a thickwalled gallbladder.…”

This report presents two cases of heterotopic gastric mucosa in the gallbladder. In case 1, the patient was a 43-year-old man who presented with diarrhea and fever. Abdominal ultrasonography showed a sessile polypoid lesion in the body of the gallbladder that grew over 2 months. Gallbladder carcinoma was suspected and a cholecystectomy was performed. Examination of an intraoperative frozen specimen of the elevated lesion in the body of the gallbladder suggested a gallbladder carcinoma invading the subserosal layer. A bile duct resection and regional lymph node dissection were performed. However, the postoperative permanent sections revealed heterotopic gastric mucosa in the gallbladder. Case 2 was an 80-year-old man. Screening abdominal ultrasonography revealed a sessile polypoid lesion in the gallbladder. This lesion was correctly diagnosed as heterotopic gastric mucosa in the gallbladder by the intraoperative frozen examination. The pertinent literature on this topic is reviewed.

“…In Japan, 18 cases of heterotopic gastric mucosa, including that in the present patient, have been reported to the present, [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] since the first case reported by Tomita et al 7 in 1977, while according to a review of the literature by Leymann et al, 25 29 cases of heterotopic gastric mucosa in the gallbladder had been reported in other countries up to 1996. The clinicopathologic features of the Japanese patients are summarized in Table 2.…”

We report on a case of heterotopic gastric mucosa in the body of the gallbladder. A 39-year-old man, who was asymptomatic, visited our hospital because of a polypoid lesion in the gallbladder, discovered during a routine health screening. Ultrasonography (US) revealed a broad-based polypoid lesion 1.7 cm in diameter in the body of the gallbladder, which was free of gallstones. The gallbladder mass was faintly enhanced by helical computed tomography. Laparoscopic cholecystectomy was performed because of the possibility of malignancy. The specimen revealed a 1.7 x 1.3 cm polypoid lesion with deep delle in the body, with no gallstones in the gallbladder. Intraoperative frozen examination yielded a diagnosis of hyperplastic polyp of the gallbladder. Histologically, the polypoid lesion consisted of gastric fundic glands located in the whole wall of the gallbladder. The surrounding mucosa consisted of almost normal epithelium without any metaplastic changes. Postoperative technetium 99m-pertechnetate scintigraphy demonstrated no evidence of gastric heterotopia elsewhere in the body. We also review 18 other reports of heterotopic gastric mucosa in the gallbladder in the Japanese medical literature.
