Renal Sinus

We report the case of a high-grade carcinoma involving the kidney in a young male with renal vein thrombosis and review the differential diagnosis and immunohistochemical workup. High-grade neoplasms involving the renal sinus include collecting duct carcinomas (CDCs), renal medullary carcinomas (RMCs), invasive high-grade urothelial carcinoma (UC) of the upper urinary tract, clear cell renal cell carcinoma, and type 2 papillary renal cell carcinoma. Distinguishing UC from CDC and RMC is problematic in small biopsy samples. The diagnosis of CDC (a rare, aggressive subtype of renal cell carcinoma) is challenging and requires the exclusion of UC. Renal medullary carcinoma is characterized by an appropriate clinical setting and consistent loss of nuclear expression of integrase interactor 1 (INI-1). A panel consisting of p63, paired box gene 8 (PAX8), and INI-1 is most optimal in distinguishing UC from CDC and RMC. A subset of urothelial carcinoma of upper urinary tract may be positive with PAX8.

Malignant Renal Tumor

Abstract Extra-adrenal myelolipomas are rare; approximately 36 cases have been reported to date. We document a case of myelolipoma presenting as a localized mass in the renal sinus of a 66-year-old man. The chief clinical and radiologic differential diagnostic considerations in this case included a malignant renal tumor arising in the hilum. The patient was being investigated for recurrent urinary tract infections and vague abdominal pains. Histologically, the lesion showed features characteristic of a myelolipoma. There was also marked chronic inflammation in and around the mass. The uneventful follow-up of 62 months is in keeping with the benign nature of this lesion. This report expands the possibilities of the differential diagnoses of renal hilar neoplasms, particularly in view of the increased use of imaging techniques that are bound to detect many incidental lesions in this region.
