Abstract:
A 74-year-old man presented to our hospital with the swelling of penis in May 2016. Physical examination revealed a goose egg-sized lump at the tip of the penis under foreskin. After dorsal skin incision we confirmed the 7 cm tumor on the inner preputial skin and then resected the tumor with circumcision. Histopathological examination revealed sarcomatoid squamous cell carcinoma of the penis. Computed tomography (CT) revealed swelling of bilateral inguinal lymph nodes, and we performed partial penectomy with bilateral superficial inguinal lymph node dissection in July 2016. Because of the positive surgical margin 2 cm away from the tumor we performed a total penectomy 2 weeks after the previous operation. Histopathological examination revealed no residual tumor and negative inguinal lymph nodes. In about 3 months postoperatively, he presented with a complaint of dyspnea and a CT scan showed right, pleural effusion and multiple lung metastases. He died of cancer 4 months postoperatively.

Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...
