Renal cell carcinoma in a horseshoe kidney treated with robot-assisted partial nephrectomy

Horseshoe kidney is one of the most common congenital renal fusion anomalies and the incidence of renal cell carcinoma in horseshoe kidney is predicted to be approximately 5.2/100000 individuals. Because horseshoe kidney merges malformations and vascular changes, open surgery is the standard for treatment. There are no reports of robot-assisted partial nephrectomy (RAPN) for renal cell carcinoma in horseshoe kidney. We describe for the first time the safety and the utility of RAPN in a horseshoe kidney with renal cell carcinoma. Keywords: Horseshoe kidney, Renal cell carcinoma, Robot, Partial nephrectom

Liposarcoma of the spermatic cord associated with scrotum lipoma: A case report and review of the literature

Liposarcoma of the spermatic cord is a rare disease and often mistakenly diagnosed as inguinal hernia, hydrocele, and lipoma. We report the case of a 58-year-old man who presented with persistent discomfort and swelling on the left inguinal region. He was diagnosed with left scrotum lipoma when he was 12 years old. He underwent high orchiectomy and wide resection of the inguinal tumor. Histopathological examination revealed a well-differentiated liposarcoma of the spermatic cord with negative resection margin and scrotum lipoma. To our knowledge, this is the first report of liposarcoma of the spermatic cord with scrotum lipoma in English literature

A Rare Case of Vascular Leiomyosarcoma Originating from a Branch Vessel of the External Iliac Vein

Leiomyosarcoma arising from the external iliac vein is uncommon. This is a report of a 51-year-old Japanese man with venous leiomyosarcoma originating from a branch vessel of the left external iliac vein. The tumor was found during a medical examination, and the patient had no symptoms. Computed tomography showed a 72 × 49 mm mass adjacent to the left external iliac vein. The tumor was resected en-block along with ligation of the external iliac vein due to strong adhesion with the tumor. Histological examination showed venous leiomyosarcoma, and its origin was thought to be a branch vessel of the left external iliac vein. The patient has remained free from recurrence at 30 months after surgery
