- Abstract
<bold>Background: </bold>Clear cell carcinomas of the pancreas are rare and more likely represent metastatic renal cell carcinoma (RCC).<bold>Methods: </bold>Twenty-one cases of metastatic RCC to the pancreas were retrieved from the files of the Endocrine Registry of the Armed Forces Institute of Pathology. Histologic features were reviewed, special stains and immunohistochemical studies were performed, and patient follow-up data were obtained.<bold>Results: </bold>The patients included 9 women and 12 men ages 47-76 years (mean, 64.4 years). Patients experienced weight loss, abdominal pain, or a mass lesion. The tumors occurred anywhere within the pancreas. The mean size of the tumors was 4.0 cm. Histologically, the tumors were comprised of clear cells with a rich vascular network. The RCC was diagnosed before (n = 17 patients; ages up to 32.7 years) or after (n = 4 patients; ages up to 13.2 years) the pancreatic metastases were discovered. Surgery was used in all patients. Adjuvant chemotherapy was used in 4 patients. From the date of the diagnosis of pancreatic metastasis, 13 patients were dead with disseminated disease (DD) (mean, 4.5 years), and 8 patients were without disease (mean, 9.0 years). From the date of the diagnosis of primary RCC, 13 patients were DD (mean, 12.7 years), and 8 patients were without disease (mean, 24.7 years).<bold>Conclusions: </bold>Although histochemical and immunohistochemical studies may help in the distinction between patients with primary versus metastatic clear cell tumors of the pancreas, clinical confirmation should be obtained. Surgical resection of the pancreatic metastatic disease is suggested, because the patient may still have a prolonged survival.
