Maxillary Sinus Mass as First Presentation of Silent Metastatic Renal Cell Carcinoma.

Renal cell carcinoma accounts for more than 3% of all malignant diseases. Metastatic disease to the head and neck ranges from 15% to 30%. The 5-year survival rate after nephrectomy is 60% to 75%, but with multiorgan metastases the 5-year survival rate is significantly lower, 0% to 7%. The authors present the case of a patient with a progressive, painless right facial swelling over the maxillary area of 3-month's duration associated with a considerable decrease of right visual acuity. Cranial computed tomography scan and magnetic resonance imaging showed a maxillary sinus mass extending to the orbital cavity and 2 choroidal and retinal thickenings. The mass biopsy was performed by Caldwell-Luc procedure and pathology report suggested metastatic renal cell carcinoma. Following histological findings, a total body computed tomography scan showed a heterogeneous mass at the middle-lower portion of the right kidney measuring approximately 8 × 12 × 4 cm with associated ipsilateral renal vein thrombosis. The patient was referred to the Oncology Department for further treatment. Unfortunately, 3 months after the mass biopsy, the patient died due to complications of multiorgan failure. Although metastases of renal cell carcinoma to the head and neck are very rare, it should be first suspected when investigating a metastatic tumor in this region.

Metastatic Renal Cell Carcinoma of the Head and Neck: A Case Series.

Background: Renal cell carcinoma (RCC) accounts for over 80% of malignant tumors arising from the kidney. However, metastatic RCC to the head and neck is a relatively rare entity. Case Presentation: We describe three patients with metastatic RCC to the head and neck with the involvement of the parapharyngeal space, the level V region of the neck, and the maxillary sinus. Conclusion: Metastatic RCC in the head and neck is uncommon; however, it must be taken into consideration given a patient with a history of RCC. Multiple pathways allow for the spread of RCC to the head and neck region. Treatment options include mastectomy or local radiation and systemic chemotherapy.

Case report. Metastatic renal cell carcinoma to the left maxillary sinus.

Metastatic tumors in the paranasal sinuses are very rare. The origin of metastatic tumors in the paranasal sinuses is often renal cancer. Renal cell carcinomas are known for their tendency for early metastasis, and symptoms due to the metastatic lesion may be the only initial manifestation. In this paper, we deal with the case of a 35-year-old male patient who presented with a mass in the left maxillary region. The presence of a primary renal cell carcinoma was recognized only after surgical removal of the metastatic tumor. The presentation, diagnosis and treatment of this tumor are discussed with a review of the literature.

Metastatic involvement of the maxillary antrum from an uncommon source.

UNLABELLED: Metastatic involvement of the jawbones is uncommon, particularly in the maxilla. Case reports of such metastases from renal cell primaries are few, making a consensus on treatment difficult to establish. We present a case of metastatic involvement of the maxilla two years following a nephrectomy for renal cell carcinoma. The case exemplifies the broad range of symptoms attributable to metastases in the maxilla and the management dilemmas. CLINICAL RELEVANCE: The case highlights the role of practitioners in primary dental care in identifying the potential for such pathology based on clinical and radiographic features.

A case of invasive meningioma involving the maxillary sinus.

Meningiomas account for nearly 15% of primary brain tumors, but extracranial meningiomas are very rare. We presented a case of invasive maxillary sinus meningioma. A 50-year-old man presented with facial tenderness and severe pain in the left cheek. He had a prior surgery for a meningioma in the left frontal lobe eight months before. Physical examination and computed tomography showed a mass in the left maxillary sinus. Histopathological result of the biopsy obtained via the Caldwell-Luc approach was invasive meningioma. The mass was removed with the sinus mucosa. The histology of the resected specimen was compatible with invasive angioblastic meningioma. Postoperative radiotherapy was administered because of residual intracranial tumor. No recurrence was detected over an 11-month follow-up period.

[Bilateral maxillary sinus metastasis of renal cell carcinoma: a case report].

A 58-year-old man presented with lasting nasal obstruction. He had undergone right nephrectomy for renal cell carcinoma 11 years ago and right lobectomy for pulmonary metastasis 10 years ago. Paranasal sinus CT scans showed a soft tissue mass in the bilateral maxillary sinus. Abdominal CT showed left renal mass. Each mass was enhanced on the contrast-enhanced viewing. The paranasal mass biopsy was performed and resulted in profuse bleeding. Pathological examination was a metastasic renal cell carcinoma. After embolization of feeding artery, debulking surgery was performed. Postoperatively he was given radiotherapy and interferon therapy.

[Metastasis in maxilar sinus as only manifestation of disseminate renal adenocarcinoma]. / Metástasis en seno maxilar como única manifestación de adenocarcinoma renal diseminado.

Paranasal sinuses and nose metastasis are very uncommon. About 50 have been reported. Renal cell carcinoma is the primary neoplasm which most frequently metastasizes in the nasosinusal region, followed by breast and lug. Symptoms are unspecific, but the epistaxis constitutes the most common sign due to the significant vascularizations of the tumor. Prognosis is poor. The survival rate fluctuates between 15-30% at 5 years. Surgery is the elective treatment.

Renal cell carcinoma metastases to the maxillary sinus.

Metastasis of renal cell carcinoma (RCC) to the head and neck region is rare. We report the case of a 65-year-old man with history of RCC, presented 7 years after nephrectomy, adrenalectomy and lung metastasectomy for his primary tumour, with symptoms of nasal obstruction, postnasal drip, productive cough and pressure sensation in the left maxillary sinus. CT revealed a unilateral, irregular opacification in the left maxillary sinus with bony erosion of the infraorbital canal wall. A yellow cystic lesion was completely removed from the maxillary sinus during functional endoscopic sinus surgery and histopathological analysis confirmed the diagnosis of a metastatic RCC. Patient continued to be managed with his pre-existing treatment for advanced RCC.

Infratemporal fossa and maxillary sinus metastases from colorectal cancer: a case report.

Head and neck metastases from colorectal carcinoma are very rare. We report on a 47-year-old woman who had a vegetating tumor located at the distal sigmoid colon with initial liver metastases. She underwent palliative transverse colostomy to prevent intestinal obstruction. She was then treated with 5-fluorouracil, leucovorin and CPT-11. At the third cycle she presented with toothache and numbness of her upper lip. Computed tomography (CT) of the head and neck showed a gross mass involving the sphenoid sinus, left maxillary sinus, left pterygopalatine plate, pterygopalatine and infratemporal fossa. Histology of the mass revealed metastatic adenocarcinoma which was similar with the primary sigmoid carcinoma. The patient underwent radiotherapy and died 2 months later. Although cranial fossa metastases from colorectal cancer are very rare, the physicians should be aware of this type of metastatic pattern in patients who suffer of toothache, painful mastication or numbness of the lips, especially if decay has not been determined.

Metastases to nasal cavity and paranasal sinuses.

The sinonasal cavities are rare locations for metastases. Metastases to these locations are usually solitary and produce similar symptoms to those of a primary sinonasal tumor. Nasal obstruction and epistaxis are the most frequent symptoms. The maxillary sinus is most frequently involved. The most common primary tumor sites to spread to this region originate in the kidney, breast, thyroid, and prostate, although any malignancy could potentially lead to a metastasis to the paranasal sinuses. The patient's prognosis is usually poor because of the fact that the sinonasal metastasis is usually associated with widespread disseminated disease. In the majority of patients, palliative therapy is the only possible treatment option. Nevertheless, whenever possible, surgical excision either alone or combined with radiotherapy may be useful for palliation of symptoms and, rarely, to achieve prolonged survival. This review considers the most interesting cases reported in the literature that presents metastases to the sinonasal cavities. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1847-1854, 2016.

Adenoid cystic carcinoma of maxillary sinus with metastatic hepatocellular carcinoma. Case report.

A case of collision tumor in the left maxillary sinus composed of adenoid cystic carcinoma (ACC) and metastatic hepatocellular carcinoma (HCC) is reported. Radiographic examination revealed masses in the liver and bilateral lung metastases. Histologically, proliferation of tumor cells with resemblance to HCC was observed, in addition to the ACC. For this reason, differential diagnosis between a second primary tumor and metastasis was made. The metastatic lesion immunohistochemically showed positivity for hepatocyte antigen (OCH1E5) and protein induced by vitamin K absence or antagonist II (PIVKA-II), sustaining the HCC diagnosis. Primary ACC and metastatic HCC in the maxillary sinus are rare, and this may therefore be the first case of maxillary sinus tumor with both these elements.

Metastatic tumours in upper maxillary bone of esophageal adenocarcinoma. A case report.

Metastases in the oral cavity are rare lesions which represent approximately 1% of all malignant neoplasms in the oral cavity. Oral metastases are located in the mandible 80-90% on average, the maxilla location being rarer. Metastases in mouth soft tissue are also rare, and within these it is on the gums where they more frequently occur. Primary tumours which metastasize to mouth are most commonly: lung, breast and kidney. Oral cavity metastases appear as a result of distant disease spreading and show wrong prognosis, with short survival. Here we present a clinical case of a patient diagnosed with esophagus adenocarcinoma which presented metastasis in upper-left maxillary bone.

Unusual metastases of lung cancer: bulbus oculi and maxillary sinus.

Lung adenocarcinoma often makes metastasis to the brain, liver, kidneys, bone, bone marrow and adrenal glands. It can also make metastasis to other parts of the body rarely for example eye, nose, parotid gland and paranasal sinus. We did not encounter with combined ocular bulbus and the maxillary sinus metastases of lung cancer in the accessible literature. In this case report, a patient who was combined ocular bulbus and the maxillary sinus metastases of lung adenocarcinoma will be discussed.

Ureteral stump metastases from renal adenocarcinoma.

The thirty-second documented case of ureteral stump metastasis from renal adenocarcinoma is presented. It demonstrates well the variable and often unusual presentation of renal adenocarcinoma and the utility of our current diagnostic instrumentation (here ureteroscopy and skinny needle biopsy) in documenting metastatic disease. Also, and in contrast to prior reports, it documents lengthy survival and a lack of extensive metastases in this high risk group of patients. The literature is reviewed and the presentation, metastatic pathways, and management of ureteral stump metastases from renal adenocarcinoma are briefly discussed.

Carcinoma of the prostate metastatic to the maxillary antrum.

Metastatic carcinoma of the maxillary antrum is an extreme rarity. Until 1980, less than 100 cases with distant primaries metastatic to the entire sinonasal tract had been reported. In a review of these cases, we found no mention of primary prostate cancer metastatic to the antrum. The purpose of this paper is to document the first case of this entity.

Retinoblastoma metastatic to the contralateral orbit.

In a 9-month-old girl a subperiosteal metastasis of the maxillary bone developed in the contralateral orbit about one year after enucleation of a poorly differentiated retinoblastoma.
