[Adenomyoma in association with early gastric carcinoma].

Described is a gastric adenomyoma associated with superficial gastric adenocarcinoma that was found in a 72-year-old male. This uncommon benign gastric lesion is believed to be developmental in origin and sometimes categorized as belonging to a subgroup of a heterotopic pancreas. Besides its rarity, an adenomyoma is also known to be a possible cause of a gastric malignancy. Although the focus of the carcinoma in our case was located in the center of the adenomyoma, this finding cannot support the etiology of a gastric carcinoma originating in an adenomyoma. However, the present case appears to imply some relationship between an adenomyoma and a gastric carcinoma.
