Prostate Cystic Adenocarcinoma / 대한비뇨기과학회지

We report a case of cystic adenocarcinoma of the prostate in a 67-year-old man who showed severe obstructive voiding symptoms. In this case, the mechanism of the cyst formation from the prostate cancer is thought to be related to the secondary cystic formation, which was due to either the central necrosis of the cancer tissue or intracancerous tissue hemorrhage. Prostate cystic adenocarcinoma is a rare disease, and there are only a few cases reported in the literature. A cyst of the prostate may be either congenital or acquired. A congenital cyst arises from the mesonephric (Wolffian) or paramesonephric (Mullerian) duct system, while an acquired cyst is subdivided into the retention, malignant, and parasitic cyst. A huge prostatic cyst was found in a 67-year-old man. The lesion was presumed to be a prostate cystic adenocarcinoma.

Chronic Inferior Vena Caval Obstruction Associated with Gross Hematuria / 대한비뇨기과학회지

Thrombosis of the inferior vena cava (IVC) is a rare condition that can result from various underlying diseases including deep vein thrombosis, major trauma, hypercoagulability disorders, and an obstruction due to tumor involvement and idiopathic causes. Chronic obstruction of the IVC may not be recognized due to the lack of signs and symptoms. Here we report a case of a chronic post-thrombotic obstruction of the inferior vena cava, which was believed to be the cause of a painless gross hematuria.
