Abstract: | We report a case of adenocarcinoma in an intrapancreatic accessory spleen (IPAS). A 78-year-old woman presented with abdominal
discomfort, and investigations revealed an elevated serum carbohydrate antigen 19-9 level, to 161.8 U/ml (normal, <37 U/ml).
Ultrasonography showed a heterogeneous echogenic tumor with a vascular hilum. Computed tomography showed a heterogeneously
enhanced tumor, 8 cm in diameter, adjacent to the pancreatic body, accompanying a feeding artery arising from the splenic
artery, and a drainage vein flowing into the splenic vein. We performed a distal pancreaticosplenectomy. The tumor was surrounded
by a fibrous capsule and was in contact with the pancreatic body. Histological examinations revealed invasive growth of adenocarcinoma
in a structure identical to the spleen. The results of both radiological and histological examinations suggested that the
tumor originated from an intrapancreatic accessory spleen. Extensive examinations revealed no other malignancy, based on which
we concluded that the adenocarcinoma was primary. Surgical intervention is strongly recommended when a malignancy in an IPAS
cannot be ruled out. |
