Primary Renal Squamous Cell Carcinoma Incidentaly Discovred in a Non-Functioning Lithiasis Kidney: A Case Report

Introduction: Primary squamous cell carcinoma of the kidney is a rare tumor with a poor prognosis. It often occurs on a lithiasis kidney. Observation: We report a case of a 62-year-old patient admitted for left back pain associated with lower urinary tract symptomes with fever. Clinical examination revealed tenderness of the left lumbar fossa. Radiological examinations showed left ureterohydronephrosis, with the presence of a left kidney stone. A left radical nephrectomy was performed showing the presence of a neoplasm measuring 7cm with on histological examination a moderately differentiated and infiltrating squamous cell carcinoma. Conclusion: The diagnosis of squamous cell carcinoma of the kidney must be evoked in the first place in front of any renal mass with notion of kidney stones.

Primary Renal Squamous Cell Carcinoma

Primary renal squamous cell carcinoma (SCC) is a rare neoplasm. It is commonly associated with long standing stone disease. The diagnosis is usually unexpected and commonly diagnosed late. The tumor is aggressive and has poor prognosis. We report a case of primary renal SCC in a 50 year old man.

Primary renal squamous cell carcinoma – A rare entity

Squamous cell carcinoma of kidney is the extremely rare entity of upper urinary tract neoplasm. The most common type of kidney cancer is clear cell renal cell carcinoma followed by papillary and chromophobe renal cell carcinoma. We report a case of renal cell carcinoma who presented with complaints of pain abdomen and hematuria. Radiologic investigation showed a renal mass and calculi in the left kidney. The patient subsequently underwent left radical nephrectomy. Pathological diagnosis of SCC of idney was made.We report a rare case of primary renal squamous cell carcinoma involving whole of the kidney. With the best of our knowledge, only few cases of primary renal squamous cell carcinoma are reported. Keywords: Squamous, Nephrolithiasis, Hydronephrosis, Pelvicalyceal System, Chromophobe.

Primary renal squamous cell carcinoma: A case report and literature review

Squamous cell carcinoma is an aggressive but rarely diagnosed cancer of the kidney. Most cases occur in association with renal calculi and thus require a high index of suspicion for their diagnosis. Though aggressive, it usually presents at a late stage and has an average 5-year survival rate of less than 10%. This is a case report of a 61-year-old male who presented with right flank pain and swelling of 4 years duration and fever and weight loss for 4 months. There was no hematuria and urinalysis and serum chemistry were within normal limits. A tumor in the right kidney was identified clinically and by computerized urography (CTU). At nephrectomy, multiple stones, hydronephrosis and pyonephrosis were found in addition to the tumor in the right kidney. Histological examination revealed squamous cell carcinoma of the kidney.

Primary renal pelvis and ureter squamous cell carcinoma (SCC): a rare case report and review of literature.

Primary renal squamous cell carcinoma (SCC) is a very rare upper urinary tract neoplasm. Renal SCC has a poor prognosis because it usually presents in advanced stages. We report a 64-year-old woman with a right paravertebral mass; after right radical nephroureterectomy and salpingo-oophorectomy, pathologic examination revealed primary SCC.

Rare Co-existence of Squamous Cell Carcinoma with Infiltration of Renal Vein and Xanthogranulomatous Pyelonephritis

Primary renal squamous cell carcinoma is a very rare malignancy of the upper urinary tract. Most patients have history of chronic urolithiasis, analgesics abuse, radiotherapy or infection. Co-existence of SCC with xanthogranulomatous pyelonephritis is exceedingly rare with only few reports in the literature. We report a case of a 60-year-old male presented with right flank pain and mild tenderness of abdomen. Computed tomography of the abdomen revealed gross hydronephrosis with parenchymal thinning and irregular thick enhancing wall of pelvicalyceal system with multiple calculi in right kidney. Right renal vein appeared distended, filled with hypo dense material. Right nephrectomy was performed and sent for pathological examination. Histological evaluation revealed keratinizing squamous cell carcinoma with infiltration of renal vein and xanthogranulomatous pyelonephritis.

Primary renal squamous cell carcinoma is a very rare clinical entity. Very few of such cases have been reported in world literature. Diverse etiological factors, non-specific clinical presentation and radiological findings of this tumor lead to difficulty in diagnosis. The diagnosis is established only after the histological examination of the resected specimen. This case which has been reported here was a case of primary renal squamous cell carcinoma in right kidney with perinephric abscess.

Primary squamous cell carcinoma of kidney - a case report of unusual local recurrence with literature review

Primary squamous cell carcinoma of the kidney is a rare clinical entity. Primary squamous cell carcinoma is more frequently reported in urinary bladder and male urethra than in kidney. Primary renal squamous cell carcinoma (RSCC) accounts for less than 5% of urothelial tumours in urinary system. Very few cases of primary squamous cell carcinoma of kidney have been reported in the world literature. Only forty-six cases over forty four years had been reported from Mayo Clinic. These neoplasms are highly aggressive and locally advanced or metastatic at the time of presentation. Here we report such a case of primary squamous cell carcinoma of kidney in a 50-year-old lady at a locally recurrent stage with fistulous tract formation. Palliative radiotherapy came out to be a good clinical modality even in locally recurrent stage in this patient.

Primary Renal Squamous Cell Carcinoma

Primary renal squamous cell carcinoma is a very rare tumour. Only a few cases have been reported in world literature. Here we report a case with renal squamous cell carcinoma. The patient presented with flank pain, fever and vomiting. In ultrasonography, renal mass was detected and after nephrectomy followed by histopathological examination, it was diagnosed as squamous cell carcinoma. There was no evidence of renal calculi or other predisposing factors. This report highlights the rarity of the tumour. DOI: http://dx.doi.org/10.3329/akmmcj.v3i2.11692 AKMMC J 2012: 3(2): 34-36

Incidentally Detected Squamous Cell Carcinoma of Renal Pelvis in Patients with Staghorn Calculi: Case Series with Review of the Literature

Squamous cell carcinoma of the renal pelvis is a rare neoplasm, often unsuspected clinically due to its rarity and ambiguous clinical and radiological features, and hence patients present at advanced stages resulting in poor prognosis. We report here four cases of incidentally diagnosed primary renal squamous cell carcinoma, treated at our hospital over a short span of one year, and review the relevant literature. Mean age of the patients (3 males, 1 female) was 60 years. All suffered from staghorn stones. Interestingly, renal carcinoma was unsuspected clinically in all patients. In one case, a computerised tomography scan showed a suspicious nodule. All underwent nephrectomy for nonfunctioning kidney. In just two cases, tumor was identified on gross examination, while the other two only showed thickened pelvis. Our series emphasises the need for pelvicalyceal biopsy during treatment for long-standing nephrolithiasis, and thorough sampling of the renal pelvis in nephrectomy specimen of such patients.
