[A Resected Case of Adenosquamous Carcinoma of Pancreas That Relapsed in Remnant Pancreas].

A 70's man underwent subtotal stomach preserving pancreatoduodenectomy(SSPPD)for pancreatic head cancer. The pathological diagnosis was adenosquamous carcinoma(ASC)of the pancreas. Two months after surgery, a recurrent tumor in the remnant pancreas was confirmed with a CT scan and suspected to be ASC by endoscopic ultrasound-guided fine needle aspiration(EUS-FNA). As the recurrent lesion was limited in the pancreas, total remnant pancreatectomy(TP)was performed 4 months after SSPPD. The final pathological diagnosis was ASC. Two months after TP, liver and para-aortic lymph node metastases were revealed. The patient has been alive for 14 months after SSPPD with chemotherapy. Because of its rarity, it is difficult to implement treatment plans for recurrent ASC in the remnant pancreas.
