Castleman's Disease (Giant Lymph Node Hyperplasia): Report of 2 cases and review of the literature

Two cases of Castleman's disease (Giant lymph node hyperplasia) are reported. The first case was a multicentric cervical giant lymph node hyperplasia. Excisional biopsy confirmed the diagnosis of Castleman's disease of the plasma-cell type. Despite repeated dissection of the cervical lymph nodes, complete removal of the lymph nodes was impossible, and the type was changed into mixed type, and regrowth of the tumor was noted. Prednisolone was of no benefit. The patient is now living with cervical masses in situ without general symptoms, 4 years after the initial diagnopsis. The second case was a solitary retroperitoneal giant lymph node hyperplasia, incidentally found. Complete excision was performed and biopsy confirmed the diagnosis of Castleman's disease of hyaline-vascular type. No recurrence was found at 2 years after the excision.

Four Primary Cancers in Abdominal Cavity

According to the development of new diagnostic tools and methods, the chance of finding multiple primary cancer has increased. However, there has never been reported in the world four primary cancers in the abdominal cavity. We report a 58 years old female who had stomach cancer, gallbladder cancer, cholangiocarcinoma, and rectal cancer in the abdominal cavity simultaneously, and was done hepato-pancreato-duodenectomy and low anterior resection was performed.
