Synchronous Renal Cell Carcinoma and Gastrointestinal Malignancies

Abstract EN

While renal cell carcinoma is the most commonly diagnosed neoplasm of the kidney, its simultaneous diagnosis with a gastrointestinal malignancy is a rare, but well reported phenomenon.

This discussion focuses on three independent cases in which each patient was diagnosed with renal cell carcinoma and a unique synchronous gastrointestinal malignancy.

Case 1 explores the diagnosis and surgical intervention of a 66-year-old male patient synchronously diagnosed with clear cell renal cell carcinoma and a carcinoid tumor of the small bowel.

Case 2 describes the diagnosis and surgical intervention of a 61-year-old male found to have clear cell renal cell carcinoma and a mucinous appendiceal neoplasm.

Lastly, Case 3 focuses on the interventions and management of a 36-year-old female diagnosed with synchronous clear cell renal carcinoma and hereditary nonpolyposis colorectal cancer.

This case series examines each distinct patient’s presentation, discusses the diagnosis, and compares and contrasts the findings while discussing the literature on this topic.
