Tubulocystic renal cell carcinoma: An entity related to papillary renal cell carcinoma?

Renal tubulocystic carcinoma is closely related to papillary renal cell carcinoma: implications for pathologic classification.

Tubulocystic carcinoma of the kidney (TC-RCC) is a rare renal tumor with unique gross and microscopic features unlike other types of renal cell carcinoma (RCC). Several recent studies recommend that it should be classified as a distinct RCC subtype. In this study, we provide pathologic and cytogenetic evidence supporting that TC-RCC is closely related to papillary RCC (PRCC). This study include...

Tubulocystic carcinoma of kidney associated with papillary renal cell carcinoma.

Tubulocystic renal cell carcinoma (TCRCC) is a rare variant of renal cell carcinoma, which has distinct histology but there is some controversy about its association with papillary renal cell carcinoma (PRCC) and cell of origin in literature. We report an 18-year-old girl with the rare TCRCC of kidney associated with PRCC with metastases to the para-aortic nodes. The patient presented with hema...

Type 2 and clear cell papillary renal cell carcinoma, and tubulocystic carcinoma: a unifying concept.

The clinical and pathological features of multiple different renal neoplasms arising in a setting of end-stage renal disease in a 72-year-old male are described. The kidney showed features of renal oncocytosis with multiple oncocytomas, hybrid tumours and chromophobe renal carcinoma. In addition, the kidney contained a type 2 papillary renal cell carcinoma, clear cell papillary and cystic renal...

An Unusual Case Report: Occurrence of Renal Cell Carcinoma, Basal Cell Carcinoma and Chronic Lymphocytic Leukemia in a Case of Papillary Thyroid Carcinoma Treated with Radioactive Iodine

The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinog...
