Resumen

Colloid carcinoma (CC) is a rare histological type of adenocarcinoma of the pancreatic duct and is characterized by the presence of large lakes of extracellular mucin containing neoplastic cells. Its 5 year prognosis is more favourable than that of ductal, tubular or not otherwise specified (NOS) adenocarcinomas. We present the case of a 74-year-old woman with a thin walled, multicystic lesion in the tail of the pancreas, radiologically suggestive of a serous cystadenoma as opposed to a mucinous neoplasm. Surgery revealed a 10 x 6 cm lesion invading the splenic hilum and transverse mesocolon. Two nodes on the wall of the gastric fundus were also removed. Histopathology showed the pancreatic tumour to be a colloid carcinoma with a synchronous gastrointestinal stromal tumour of the gastric fundus.
