A case of a solitary, unilateral, large metastatic renal tumor found 35 years after the detection of primary thyroid carcinoma is presented. Renal metastasis from thyroid carcinoma detected during life is extremely rare, and there may be a long latency period before the appearance of a secondary tumor. The possibility of a secondary tumor should always be considered in the differential diagnosis of renal neoplasms, even when the tumor is a large, unilateral, solitary renal mass.

A 16-year old female presented painful masses in the lumbar region 5 years after the initial diagnosis of a localized osteosarcoma of the tibia. Abdominal X-ray revealed calcified masses. A bone scan confirmed an increased uptake in the renal areas. An ultrasound-guided fine needle biopsy confirmed the diagnosis of metastases. The procedure was complicated by subcapsular hemorrhage and gross hematuria. Renal metastases from osteosarcoma are usually asymptomatic and invisible on abdominal X-rays. The diagnosis is generally established by radionuclide bone scan or abdominal CT-scan. Our observation suggests that histological documentation of these unusual clinical presentations should be carefully weighed against the risk of the procedure.

Renal metastases in the evolution of an esophagus epidermoid carcinoma are rare and are frequently bilateral or associated with many other metastases. The authors present an original article of a single metastasis. They discuss the importance of imagery and locoregional status in the management of patient.

Herein, a case of solitary, unilateral renal metastasis in a patient with curatively resected thoracic esophageal carcinoma, who achieved a pathological complete remission after neoadjuvant concurrent chemoradiotherapy, is reported. The kidney is the 4(th) or 5(th) most common visceral metastasis site of a primary esophageal carcinoma. More than 50% of renal metastases typically show bilateral involvement. Solitary, unilateral renal metastasis is extremely rare. Renal metastases from a primary esophageal carcinoma are usually latent and its diagnosis is very unusual in a live patient. The solitary renal metastasis in this case was not accompanied by metastases to other sites. The value of a nephrectomy in solitary renal metastasis of esophageal cancer is not known due to the rarity of such cases. A nephrectomy could be justified in limited situations, such as with uncertainty of histological diagnosis, severe life-threatening hematuria, which cannot be controlled by embolization, or solitary renal metastasis with a long disease-free interval.

Renal metastasis from primary colon cancer is very rare, comprising less than 3% of secondary renal neoplasms. There are just 11 cases reported in the medical literature of colonic adenocarcinoma metastatic to the kidney. Of these cases, none occurred via direct invasion. We report a unique case of a 51-year-old female with extraluminal colonic adenocarcinoma which directly invaded into the kidney. Additionally, we investigate the causal relationship between the site of invasion and a previous stab injury by reviewing the role of the peritoneum and Gerota's fascia in preventing the spread of metastatic cancer into the perirenal space. Due to the rarity of this event, we present this case including a review of the existing literature relative to the diagnosis and treatment.

Renal metastases from thyroid carcinoma are very rare, late recurrences of papillary thyroid carcinomas (PTC) are not reported in literature and there is no universal recommendation for optimum duration of follow-up of thyroid carcinoma. We present herein a case of late renal recurrence of follicular variant PTC (FV-PTC). This study is a case report of renal metastasis revealing a late recurrence of FV-PTC. An 81-year-old woman with previously treated FV-PTC 24 years ago by total thyroidectomy, lymph nodes dissection and radioiodine therapy presented with sudden gross-hematuria. Computerized tomography scan (CT-scan) revealed a 70-mm right renal mass and histological diagnosis after nephrectomy demonstrated recurrence of FV-PTC with a positive thyroglobulin immunostaining. Despite of (131)I-radioiodine therapy postoperatively, the serum thyroglobulin (Tg) increased and positron emission tomography combined to CT-scan showed 4 years later, an abdominal lymph node and distant metastases. Now the patient is alive but her general condition is too poor for systemic adjuvant therapy. This case illustrates the need of prolonged follow-up after surgery of high-risk FV-PTC.

Renal metastasis from prostatic origin is an uncommon event. Advanced prostate cancer locally invades the seminal vesicles, bladder and regional lymph nodes. Other metastatic sites are the lung, bone and other visceral organs. We present a 55-year old, Hausa man from Northern Nigeria who was managed as a case of infected renal cyst which later turned out to be a metastatic prostatic adenocarcinoma with a rare pattern of widespread bony metastases.Renal metastasis from prostate adenocarcinoma is a rare occurrence, however, high level of suspicion is needed in order to avoid potential diagnostic pitfall.

Renal metastasis of a submandibular gland adenoid cystic carcinoma is clinically rare when it presents with an atypical imaging appearance of singular renal metastases. Whole-body positron emission tomography (PET)/computed tomography (CT) can determine whether the singular renal mass is benign or malignant and identify metastases in other parts of the body, particularly in uncommon sites. In the present case, the patient developed a rare partial metastasis to the right kidney three years after undergoing a surgery for submandibular gland adenoid cystic carcinoma. Based on the present case, whole-body PET/CT examination could provide an important basis for making treatment plans for singular renal metastases.

The common sites of breast cancer metastases include bones, lung, brain, and liver. Renal metastasis from the breast is rare. We report a case of breast cancer metastatic to the kidney with extension into the renal vein. A 40-year-old woman had undergone left mastectomy for breast cancer at the age of 38. A gastric tumor, which was later proved to be metastasis from breast cancer, was detected by endoscopy. Computed tomography performed for further examination of the gastric tumor revealed a large left renal tumor with extension into the left renal vein. It mimicked a primary renal tumor. Percutaneous biopsy of the renal tumor confirmed metastasis from breast cancer. Surgical intervention of the stomach and the kidney was avoided, and she was treated with systemic chemotherapy. Breast cancer metastatic to the kidney may present a solitary renal mass with extension into the renal vein, which mimics a primary renal tumor.

Differentiated thyroid carcinoma (DTC) though usually behaves in an indolent manner, can have unusual metastatic presentation. Initial presentation of metastatic disease has been reported in 1-12% of DTC being less frequent in papillary (~2%) than in follicular (~10%) thyroid carcinoma. Renal metastasis from DTC is very rare. To our knowledge, only about 30 cases have been reported in the English literature to date. To make clinicians aware that management of such high-risk thyroid cancer frequently requires novel multimodality imaging and therapeutic techniques. A 72-year-old female is described who presented with abdominal pain and bilateral lower limbs swelling. Initial contrast enhanced computed tomography (CT) scan of abdomen showed a well-encapsulated mass in the upper pole of right kidney favoring a renal cell carcinoma. Postright sided radical nephrectomy, histopathology, and immunohistochemistry reports suggested metastatic deposits from thyroid malignancy. 18F-fluorodeoxyglucose (FDG) positron emission tomography-CT demonstrated hypermetabolic nodule in the left lobe of thyroid and a lytic lesion involving left acetabulum suggestive of skeletal metastasis. Subsequently, ultrasound-guided fine needle aspiration cytology of the thyroid nodules in bilateral lobes confirmed thyroid malignancy (Bethesda 6/6). Total thyroidectomy revealed papillary thyroid cancer (PTC) (follicular variant-PTC [FV-PTC]). After surgery, 131I-whole body scan showed iodine avid lytic lesion in the left acetabulum. The present case is a rare scenario of a renal metastasis as the presenting feature of an FV-PTC. Dual avidity in metastatic thyroid cancers (iodine and FDG) is rare and based on the degree of dedifferentiation of the DTC.
