Synchronous microcystic adnexal carcinoma and gastric cancer with review of the literature.
A microcystic adnexal carcinoma (MAC) on the left lateral chest was synchronously accompanied by both an adenocarcinoma and a granular cell tumor of the stomach in a 70-year-old Japanese male. The MAC lesion had first appeared approximately 20 years earlier and had slowly increased without symptoms. After a definitive diagnosis was made by an excisional biopsy, a second operation was performed with wider excision, followed by split thickness skin grafting. Meanwhile, a punch biopsy from an erosive lesion, which was performed three days before the second operation, demonstrated gastric cancer. Consequently, a gastrectomy was undertaken 20 days later. The patient had since been followed for 2 years and 3 months without any sign of recurrence nor metastasis. Subsequently, soft lymph nodes in two regions of the left axilla were noticed. Three lymph nodes were excised for diagnostic purposes and found to be reactive hyperplasia without metastasis of skin tumor cells. To our knowledge, in the literature, 11 patients have been reported with MAC associated with double or multiple cancers which developed syn- or meta-chronously; ours is the 12th patient.
