Renal cell carcinoma with metastases to the triquetrum: case report

Metastatic tumors of the hand are rare, with fewer than 200 cases reported in the literature. Renal cell carcinoma is among the most common tumors to metastasize, but we are not aware of reports of this tumor metastasizing to the carpal bones. We describe a case of renal cell carcinoma that metastasized to the triquetrum to draw attention to the potential for such lesions developing within the hand and wrist.     

Renal cell carcinoma with solitary metachronous metastasis to the urinary bladder

We report a case of renal cell carcinoma with solitary metachronous metastasis to the urinary bladder occurring 6 years after radical nephrectomy. The patient was treated with partial cystectomy and survived for 60 months. Other cases like this one were reviewed in published reports, and the 3-year survival rate for patients with this type of cancer with solitary metastasis to the urinary bladder was found to be 80%. The follow-up duration of our case was the longest in the published studies. We suggest that urinary bladder metastasis of renal cell carcinoma should be resected because no effective treatment for metastatic renal cell carcinoma is available. A good prognosis may be expected, especially in patients with solitary metastasis to the urinary bladder.     

Renal cell carcinoma with solitary synchronous pancreaticoduodenal and metachronous periprostatic metastases: Report of a case

Renal cell carcinoma metastases to gallbladder

A 74-year old man underwent a radical cholecystectomy for presumed gallbladder cancer. The histology of the resected specimen in fact revealed the lesion to be metastatic renal cell carcinoma from his resected right nephrectomy performed 14 years previously.     

Multiple metachronous brain metastases from primary ureteral carcinoma

Transitional cell carcinoma (TCC) of the ureter is an uncommon urologic malignancy, with approximately 150 cases diagnosed annually. Metastatic brain disease from ureteral TCC is exceedingly rare. To our knowledge, our case report represents only the second report of brain metastasis from ureteral TCC and the only reported patient to undergo resection of their TCC brain metastasis.     

Massive metachronous inguinal metastases of carcinoma of the anal margin. A clinical case report]

The authors report a case of epidermoid carcinoma of the anal margin with repeated metachronous metastases in the inguinal lymph nodes. The treatment of synchronous ad metachronous metastases is briefly discussed through a literature review.     

Renal cell carcinoma with solitary metastases to pericardium

Approximately 1 to 3 per cent of patients presenting with metastatic renal cell carcinoma will have a solitary metastatic lesion. An unusual case of solitary metastasis is described. Treatment consisted of nephrectomy and radiation therapy to the pericardium.     

Renal cell carcinoma metastases to the thyroid gland -- report of 3 cases and review of the literature

Clinically significant, solitary metastasis to the thyroid gland is a rare occurrence. The clear cell carcinoma of the kidney (RCC) is the most common primary tumor site. Late recurrence is a notable feature of renal carcinoma. Solitary metastases in the thyroid gland occur as late as 100-120 months from the date of nephrectomy. There is a clear survival benefit in selected cases if surgical approach to the thyroid metastases is chosen. In those patients who have undergone complete resection, 5-year-survival-rates of 50 % have been reported. We describe 3 cases of surgically treated thyroid metastases of RCC, and review the literature.     

Renal metastases from carcinoma of the lung

Five cases of clinically manifest solitary and bilateral renal lesions metastatic from the lung are presented. These cases are unusual in that renal metastases are usually silent lesions discovered at autopsy. Review of the autopsy data from this hospital identified renal metastases in 19% of patients who died from carcinoma of the lung. This incidence parallels that of other series. A solid renal lesion which is identified in a patient with a history of pulmonary carcinoma should raise the suspicion of renal metastases, especially if computed tomography of the mass demonstrates relative homogeneity and minimal enhancement. More frequent use of the abdominal CT scan in staging patients with lung cancer will render metastatic carcinoma from lung to kidney a more frequent ante mortem diagnosis.     

Simultaneous and metachronous pelvic bone metastases from renal cell carcinoma necessitating hemipelvectomy: report of two cases]

Two patients, one with and one without a history of nephrectomy for renal cell carcinoma, presented with lower abdominal pain. One of them, a 49-year-old man, had tumors in the right kidney and the right ischiadic bone. He underwent nephrectomy and pathologic findings showed renal cell carcinoma (tubular type, granular cell subtype, INF-gamma, G2). The other patient, a 33-year-old man with a previous history of left nephrectomy for renal cell carcinoma (tubular type, granular cell subtype, INF-alpha, G2), was found to have a large tumor in the pelvis, extending from the pubic and iliac bones to the hip joint. Both patients underwent embolization of the hypervascular mass using a vascular coil followed by hemipelvectomy under general anesthesia. The pathology reports confirmed bone metastases from renal cell carcinoma. Both patients survived surgery and their postoperative courses were uneventful without urinary or bowel incontinence. However, impaired potency was noted in the latter case. Immunotherapy with INF-alpha was resumed immediately after surgery.     

Renal cell carcinoma presenting as an ominous metachronous scalp metastasis

Renal cell carcinoma (RCC) accounts for 3% all of solid organ tumours and is slightly more common in men in the age range of 60 to 70 years. Skin metastases occur in 3% to 6% of RCCs. There are only approximately 30 cases of scalp metastases secondary to RCC in the literature. They usually occur late in metastatic disease and are a bad prognostic marker. A 67-year-old Caucasian male presented with a metastatic scalp lesion, 10 years post-radical treatment for RCC. His initial diagnosis was a T3bN0M0 RCC. He presented with a raised erythematous lesion on his parietal scalp, the histology of which demonstrated late metastatic recurrence. Shortly after this, he developed diffuse metastatic disease. Metastatic RCC can occur many years after initial diagnosis and present in many forms. Cutaneous metastatic lesions of RCC can mimic many other dermatologic conditions and carries an ominous prognosis. It is therefore important not only for the urologist, but also general practitioners and patients to be vigilant of any new skin lesion as a portent of impending metastatic disease.     

Renal cell carcinoma with bilateral adrenal and small intestinal metastases: a case report

A 69-year-old man who had a complaint of melena and hematemesis was referred to our hospital for further evaluation and treatment of renal masses, bilateral adrenal swelling and a tumor in the small intestine. The abdominal CT scan demonstrated two tumors sized 45 mm and 15 mm in diameter, located in the center and lower pole of the left kidney. Bilateral adrenal swelling and a small intestinal tumor with invagination were also observed. We diagnosed left renal cell carcinomas with bilateral adrenal metastases or hyperplasia, and a primary or metastatic small intestinal tumor. He received left radical nephrectomy, right adrenalectomy, and small intestinal resection. Pathological diagnosis was renal cell carcinoma, granular cell carcinoma, G2>G3>G1, INFalpha, v (+), pT1a, pM1, Stage IV. Bilateral adrenal swelling and small intestinal tumor were metastases from the renal cell carcinoma After operation, we administered interferon-alpha and steroid replacement. He died after 27-month follow-up period because of renal cell carcinoma. Renal cell carcinoma with simultaneous metastases to bilateral adrenal glands and the small intestine is extremely rare.     

Renal carcinoma metastatic to the peritoneum. Case report

OBJECTIVE: We describe the case of a young male presenting with non-specific abdominal symptoms on follow-up after radical nephrectomy for renal carcinoma leading to the finding of local recurrence and peritoneal metastases. A second exploratory laparotomy was carried out for tumor reduction, but it was followed by fast peritoneal recurrence. Despite the treatment with alpha interferon, three months later he developed multiple hepatic metastases. CONCLUSIONS: Peritoneal involvement by renal cell carcinoma is rare and implies a bad prognosis.
