Ciliated muconodular papillary tumor of the lung: A report of five cases.

Ciliated muconodular papillary tumor (CMPT) of the lung is a newly defined and extremely rare tumor characterized by a papillary growth pattern, consisting of ciliated columnar cells, mucous cells, and basal cells with abundant mucin production. Tumor definitions and clinicopathological features continue to be debated. Herein, we report five surgical cases of CMPT to characterize its radiographic, gross, and microscopic features.

[A case of pancreatic mucinous carcinoma with special reference to diagnostic usefulness of contrast enhanced ultrasonography].

A 72-year-old man was admitted to our hospital for further investigation of pancreatic mass. Ultrasonography revealed hypoechoic mass with hyperechoic and aechoic area. Contrast enhanced ultrasonography (CE-US) revealed a vascular image in the lesion.

Prophylactic clip application does not decrease delayed bleeding after colonoscopic polypectomy.

Background: The most common major complication of colonoscopic polypectomy is postpolypectomy hemorrhage. Although several factors have been implicated in the occurrence of hemorrhage, accurate prediction of delayed bleeding remains difficult. This randomized controlled trial evaluated the efficacy of prophylactic clip application for prevention of delayed postpolypectomy bleeding.
