Abstract:
A low-grade tubular-mucinous renal neoplasm (LGTMRN) is a recently established renal tumor, which was thought to be of collecting duct origin. A 43-year-old man presented with acute abdominal pain and underwent abdominopelvic computed tomography (CT). The CT scan showed a 5cm sized low contrast attenuated homogeneous renal mass in the mid portion of the left kidney. A left radical nephrectomy was performed and the cut-section revealed a well-demarcated, homogeneous and dark-yellowish mass confined to the renal parenchyme, and a focal hemorrhage was also seen. A histological examination showed predominant tubular growth, with focal intraluminal and stromal mucin depositions and aggregates of foamy histiocytes. No infiltrative growth and significant nuclear atypia were found. These findings were compatible with a low-grade tubular-mucinous renal neoplasm.
