Spontaneous Remission of Minimal Change Disease in a Colon Cancer Patient: A Case Report.

ABSTRACT

Introduction: Minimal change disease (MCD) is most often primary but may occur secondary to other systemic diseases such as malignancy. In secondary MCD, spontaneous remission of nephrotic syndrome after the treatment of related diseases without steroid therapy is rare. Case Presentation A 78-year-old man visited the outpatient clinic with foamy urine and generalized edema that had persisted for 2 months. The patient had nephrotic syndrome. Before a kidney biopsy, he underwent several tests to determine the secondary cause of the nephrotic syndrome. The serum CEA was slightly elevated, and colon cancer was detected in the sigmoid colon. MCD was diagnosed from a kidney biopsy. He immediately underwent surgery for colon cancer. Complete remission of the MCD was achieved within 2 weeks after surgery. Conclusion: Here, we report a rare case of a patient with secondary MCD who successfully achieved spontaneous remission after colon cancer surgery.
