Primary pancreatic lymphoma forming a giant mass in a short period: A case report.
A 69 year old man with chief complaints of vomiting and nausea was referred to our hospital. Ultrasonographic examination on 19 May 1998 showed a hypoechoic homogeneous mass 6 cm in diameter in the head of the pancreas. Degree of intravascular infiltration was angiographically mild despite its large size. Tumor-marker levels were normal. On 9 August 1998, however, ultrasonography showed the mass to have rapidly grown (10 cm in diameter) including a heterogeneous internal structure. The mass had a linear or branching signal pattern.
