Introduction:
Primary small cell carcinoma (SCC) after renal transplantation is very rare. Here, we reported 1 case of primary SCC after renal transplantation and analyzed its clinical and pathological characteristics.
Case Presentation:
A 55-year-old female underwent renal transplantation in our hospital 2 years ago and had been using tacrolimus for immunosuppressive therapy. Because of abdominal distention, the patient was admitted to our hospital. Computed tomography (CT) showed a malignant tumor of left kidney. Patient underwent surgical treatment and radical nephrectomy and lymph node dissection were selected. Postoperative pathological diagnosis was primary renal parenchyma and ureteral SCC. The patient has been treated with combination chemotherapy of lowpol (100 mg per day) and etoposide (10 mg per day). His vital signs are stable now, and he is receiving further treatment in our hospital.
Conclusion:
Because of immunosuppressive drugs use, the incidence of malignancies has increased significantly after renal transplantation. This case highlights the difficulty of diagnosis of primary SCC and the necessity of checking for neuroendocrine tumor after organ transplantation.
