Tumour immune microenvironment in primary and metastatic papillary renal cell carcinoma

Histopathology, 2020
Among renal cell carcinoma (RCC) the tumour immune microenvironment has been best characterised in clear cell RCC. In this study we investigated the expression of several immune markers, including PD‐L1, FoxP3 and CD8 in primary and metastatic papillary ...

Papillary Renal Cell Carcinoma

Acta Pathologica Japonica, 1992
Papillary renal cell carcinoma is an uncommon variant of renal cell carcinoma which has unique features including hypovascularity or avascularity, extensive stromal macrophage infiltration and better prognosis than that for nonpapillary renal cell carcinoma.

DNA hypermethylation in papillary renal cell carcinoma

BJU International, 2011
What’s known on the subject? and What does the study add? Epigenetic alterations play an essential role during carcinogenesis, and earlier studies suggested that global histone modification levels are predictive for patients’ outcome in various tumour entities (e.g. prostate, lung, breast and kidney cancer).

Defining clear cell papillary renal cell carcinoma in routine clinical practice

Histopathology, 2020
We recently encountered an 87-year-old male patient, who presented with recent onset of lumbar radiculopathy. Over seven years prior to the radiculopathy, he was found to have a 3.2 cm renal mass that was radiologically stable on initial active ...

Papillary renal cell carcinoma in allograft kidney

European Radiology, 2004
Papillary renal cell carcinoma is a subgroup of malignant renal epithelial neoplasms. Its occurrence in allograft transplanted kidney has not been debated in the literature. We report two pathologically proven cases and discuss the clinical hypothesis for such neoplasms and the aspect on MR images. The paramagnetic effect of the iron associated with an

Papillary Renal Cell Carcinoma With Cutaneous Metastases

The American Journal of the Medical Sciences, 2010
Cutaneous metastasis is a rare form of presentation of renal cell carcinoma (RCC). Case reports and case series of RCC with skin metastasis in the English literature from 1972 to 2008 were identified by searching the keywords "renal cell cancer," "papillary renal cell tumor," "skin metastasis," and "cutaneous metastasis" in the National Library of ...

A case of oncocytic papillary renal cell carcinoma

International Journal of Urology, 2009
AbstractPapillary renal cell carcinomas (RCC) are the second most frequently identified pathological subtypes of RCC. Occasionally, papillary RCC demonstrate pathological characteristics of renal oncocytomas (RO), benign renal tumors. We report the case of an 81‐year‐old woman with an oncocytic papillary RCC, which was difficult to differentiate from a

A Case of Ossifying Papillary Renal Cell Carcinoma

Urology, 2012
Osseous metaplasia can occur in renal cell carcinomas. We report a case of a 52-year-old lady who presented with hematuria. Ossification associated with a renal cell carcinoma was demonstrated on computed tomography urography and confirmed by histopathologic examination.

Is hypervascular papillary renal cell carcinoma present?

Abdominal Radiology, 2020
We aimed to investigate atypical papillary renal cell carcinoma (PRCC) presenting with early contrast enhancement and late washout and to investigate the correlation between the CT attenuation value of the corticomedullary phase (CMP) of contrast-enhanced CT in PRCCs and the endothelial cell counts of these tumors.Twenty-two patients with ...
