Metastasis of the gallbladder in clear cell renal carcinoma

Late Onset of Pancreatic Metastases from Renal Cell Carcinoma. A Case Report

Metastasis of renal cell carcinoma (RCC) to the pancreas is a rare entity accounting only 0.25-3% of all pancreatic tumors. We present a rare case of isolated three focal pancreatic metastases from RCC, occurring 15 years after the left nephrectomy. The majority of the pancreatic metastases are asymptomatic, as it was in case of our patient excluding the weight loss for the last three months. We demonstrate the importance of the medical history, radiological examinations, histological and immunohistochemical analysis in making a definitive diagnosis.

The Unusual Presentation of a Single Case of Synchronous Metastatic Clear Cell Renal Cell Carcinoma to the Gallbladder: A Case Report and Literature Review

Clear cell renal cell carcinoma, accounts for approximately 70% of all adult renal tumors. This disease is well known for its high metastatic potential, with estimates of 25-50% of patients reporting metastasis to distant structures. However, there have only been several reported cases in medical literature describing hematogenous spread to the gallbladder, with the majority occurring metachronously, in males, and with multiple metastases. This case report follows an extremely unique presentation in a 60-year-old female. Although the patient did not exhibit the usual signs and symptoms or meet the typical demographics seen with metastatic renal cell carcinoma, it should find a place on the differential diagnosis list when a gallbladder lesion is detected on imaging during the initial staging and/or restaging in patients with renal-cell carcinoma.

Uncommon site of metastasis from renal cell carcinoma: Case report

BACKGROUND

Renal cell carcinomas (CCR) account for 90% of renal tumors. Presence of latent distant metastasis is characteristic of RCC and may manifest more than a decade after nephrectomy. Gallbladder (GB) is a rare site of metastasis, with few reports in the literature. A case of metastasis from RCC to GB nine years after initial diagnosis is reported herein.

CASE REPORT

Male patient, 74 years, nine years post right radical nephrectomy for grade 2 clear-cell adenocarcinoma, T3BN0M0. During onset, Magnetic Resonance Imaging (MRI) evidenced T2-weighted hypointense and T1-weighted hyperintense lesion, with early and persistente contrast enhancement and exophytic bulging of the underlying outer vesicular margin. T1-weighted hypointense and T2-weighted slightly hyperintense nodular formation was also evidenced in the body portion of the pancreas, with 1.5 × 1.2 cm. The patient was subjected to videolaparoscopic cholecystectomy associated to endoscopic ultrasound (EUS) intraoperatively for investigation of the pancreatic nodule. The anatomopathological examination of the gallbladder was compatible with infiltrating metastasis from clear-cell carcinoma of primary renal site. A solid, hypoechoic, oval nodule with 14 mm was found at EUS, which cytology was suggestive of clear-cell Carcinoma. Because this is an indolent disease with oligometastasis, local ablative treatment with fractionated stereotactic radiation therapy with a dose of 40 Gy was selected. The patient is found with stable disease one year after radiation therapy.

CONCLUSION

Gallbladder is an unusual site of RCC metastasis. In patients with history of this disease, all vesicular lesions should be given attention, even where the primary tumor has been treated many years before.

Metastatic polyp of the gallbladder from renal cell carcinoma

Background

Gallbladder metastasis from renal cell carcinoma (RCC) is extremely rare. The purpose of this study is to clarify the characteristics of metastatic RCC to gallbladder.

Methods

The pooled data for analysis were collected from the case of metastatic RCC to gallbladder encountered by our institution along with sporadic cases reported in literature from 1991 to 2015.

Results

A total of 50 cases of metastatic RCC to gallbladder were recruited for study. Fifty-seven percentage of the primary RCC was from the right kidney and 43% from the left. The median interval between diagnoses of primary and metastatic RCC to gallbladder was 36 months, with the longest duration up to 324 months. Most (70%) were asymptomatic. The size of metastatic RCC to gallbladder ranged from 0.8 cm to 9 cm, with median of 2.6 cm. Majority (91%) of the metastatic RCCs presented as a polypoid mass with narrow stalk, and 82% were hypervascular lesion. The overall 1 year, 3 year and 5 year survival rate was 91.5%, 76.2% and 59.3% respectively, with a median of 26.5 months. Number of the metastatic site, timing of gallbladder metastasis, symptom, tumor size and operation type of cholecystectomy seemed to have no impact on survival.

Conclusions

Metastatic RCC to the gallbladder should be taken into account for a gallbladder polypoid mass with narrow hypervascular stalk during the diagnosis and/or follow-up of primary RCC. Gallbladder metastasis from RCC is not necessarily to be an advanced stage with poor outcome, and cholecystectomy is recommended whenever possible.

Metachronous gallbladder metastasis from renal cell carcinoma-a rare clinical manifestation

Renal cell carcinoma (RCC) represents a rare tumor entity accounting for approximately 3 % of all malignancies in the adult population. Approximately 30 % of all patients suffering from RCC develop metastases after nephrectomy and another 30 % of patients suffer from synchronous metastases at the date of diagnosis. Gallbladder metastases represent an extremely rare clinical condition and up to date there are only 35 published cases of gallbladder metastasis from RCC. Surgical resection should be the treatment of choice in any case based on the reported data in literature. In spite of the small series of cases, survival can be improved even in patients suffering from additional sites of metastases.

Contribute to the comprehension of rare mestatic disease in clear cell renal carcinoma.

•

Underline that non only primary tumors develop in the gallbladder.

•

Increasing suspect of metastatic disease in patients with renal cell carcinoma will improve medical care of this patients.

Introduction

Clear cell renal cell carcinoma (ccRCC) is well known for its propensity to metastasize to unusual sites, even after 10 years. Gallbladder metastases are extremely rare, being found in approximately 0.6% of cases, at autopsy.

Case presentation

A 51-year-old man with a history of right ccRCC underwent total nephrectomy with extended lymphadenectomy, in another Hospital. Three years later, he was hospitalized at our Hospital, with gallbladder metastasis detected during a follow-up CT scan. At clinical examination, the patient did not present any symptoms or signs of gallbladder disease. Several imaging tests were performed to better characterize the lesion. A successful cholecystectomy and hepatic resection of 4b segment were performed, obtaining a R0 resection. The clinical course was uneventful, without any complications. After a 7-month follow-up, the patient is free from disease.

Discussion

A typical metastases are those located in a site other than thoracic, skeletal, hepatic, adrenal or encephalic tissue. Cholecystectomy with R0 resection has demonstrated to be the only factor increasing survival, mainly in isolated cases of metastasis, providing an overall 35–60% survival rate at 5 years.

Conclusion

In the follow-up of patients with a positive history of renal cell carcinoma specially clear cell subtype, all new finding should be taken into account as possible metastases. We ought to consider US and CT-scan behavior of gallbladder metastatic disease in order to orientate our diagnosis. Surgery for metastatic gallbladder disease of renal origin seems to be a feasible therapy which is capable of increasing patients’ overall survival.

Gallbladder metastasis from renal cell carcinoma: a case report with review of the literature

We experienced a rare case of gallbladder metastasis from renal cell carcinoma (RCC). Ultrasound, computed tomographic, and magnetic resonance findings showed a hypervascular polypoid mass and correlated well with histopathologic findings. The mass showed high intensity on diffusion-weighted images, and the apparent diffusion coefficient was relatively low. These imaging findings are considered characteristic and may assist preoperative diagnosis in patients with history of RCC.

A gallbladder tumor revealing metastatic clear cell renal carcinoma: report of case and review of literature

Metastatic renal cell carcinoma in the gallbladder is extremely rare, with reported frequencies of less than 0.6% in large autopsy reviews. Only 40 cases were reported in the literature. We report a first case of gallbladder polypoid tumor revealing metastatic clear cell renal cell carcinoma, which demonstrates the importance of radiological tests, histology and immunohistochemistry when making a definitive diagnosis. These examinations also allow differentiating metastatic clear cell renal cell carcinoma from other polypoid lesions in the gallbladder with clear cell morphology. Cholecystectomy should be performed to obtain a definitive diagnosis and to improve survival in case of solitary metastatic renal cell carcinoma.
