Tubulocystic Carcinoma of the Kidney

The median patient age was 60 years, median of tumor thickness 2.3 mm and median of Clark’s level of penetration 3. Positive lymph nodes were shown in 48% of cases. All markers were expressed at higher values in melanoma cells than in surrounding tissue. MMP2 was more prominent in the zone with strong lymphocyte infiltration (P=0.018) and deeper layers of tumor penetration. MMP2 exhibited stron...

Tubulocystic carcinoma of the kidney.

Tubulocystic carcinoma (TCC) of the kidney is a unique, rare, and recently recognized neoplasm. Although originally considered a low-grade collecting duct carcinoma, TCC is now considered to be a distinct entity. TCC should be considered in the differential diagnosis of cystic renal neoplasms. We report a case of TCC arising in the left kidney.

Rethinking about tubulocystic carcinoma of the kidney after taking into account the existence of tubulocystic chromophobe renal carcinoma.

Chromophobe renal cell carcinoma (ChRCC) is a variant of RCC with certain histological, immunohistological and cytogenetic characteristics. It is believed to arise from the intercalated cells of distal tubules and has a more favourable prognosis than other more common subtypes, clear cell and papillary RCC. Microscopically, neoplastic cells of ChRCC are typically arranged in solid sheets, trabe...

Tubulocystic Carcinoma of the Kidney, a Rare Distinct Entity

Tubulocystic Renal Cell Carcinoma: A Rare Renal Tumor

Tubulocystic renal cell carcinoma of the kidney is a rare entity with less than one hundred cases reported so far. It was previously considered to have some similarities to various other renal cancers although this tumor has distinct macroscopic, microscopic and immuno-histochemical features. It is now a well-established entity in renal neoplastic pathology and has been recognized as a distinct...
