Abstract
Several solid lesions can be found within the pancreas mainly arising from the exocrine and endocrine pancreatic tissue. Among all pancreatic malignancies, the most common subtype is pancreatic ductal adenocarcinoma (PDAC), to a point that pancreatic cancer and PDAC are used interchangeably. But, in addition to PDAC, and to the other most common and well-known solid lesions, either related to benign conditions, such as pancreatitis, or not so benign, such as pancreatic neuroendocrine neoplasms (pNENs), there are solid pancreatic lesions considered rare due to their low incidence. These lesions may originate from a cell line with a differentiation other than exocrine/endocrine, such as from the nerve sheath as for pancreatic schwannoma or from mesenchymal cells as for solitary fibrous tumour. These rare solid pancreatic lesions may show a behaviour that ranges in a benign to highly aggressive malignant spectrum. This review includes cases of an intrapancreatic accessory spleen, pancreatic tuberculosis, solid serous cystadenoma, solid pseudopapillary tumour, pancreatic schwannoma, purely intraductal neuroendocrine tumour, pancreatic fibrous solitary tumour, acinar cell carcinoma, undifferentiated carcinoma with osteoclastic-like giant cells, adenosquamous carcinoma, colloid carcinoma of the pancreas, primary leiomyosarcoma of the pancreas, primary and secondary pancreatic lymphoma and metastases within the pancreas. Therefore, it is important to determine the correct diagnosis to ensure optimal patient management. Because of their rarity, their existence is less well known and, when depicted, in most cases incidentally, the correct diagnosis remains challenging. However, there are some typical imaging features present on cross-sectional imaging modalities that, taken into account with the clinical and biological context, contribute substantially to achieve the correct diagnosis.

Utility of CT to Differentiate Pancreatic Parenchymal Metastasis from Pancreatic Ductal Adenocarcinoma. Cancers (Basel) 2021; 13:cancers13133103. [PMID: 34206263 PMCID: PMC8268077 DOI: 10.3390/cancers13133103] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 05/29/2021] [Accepted: 06/18/2021] [Indexed: 02/06/2023] Open
Abstract
Simple Summary The purpose of this retrospective study was to report the computed tomography (CT) features of pancreatic parenchymal metastasis (PPM) and identify CT features that may help discriminate between PPM and PDAC. At multivariable analysis, well-defined margins (OR, 6.64; 95% CI: 1.47–29.93; p = 0.014), maximal enhancement during arterial phase (OR, 6.15; 95% CI: 1.13–33.51; p = 0.036), no vessel involvement (OR, 7.19; 95% CI: 1.51–34.14) and no Wirsung duct dilatation (OR, 10.63; 95% CI: 2.27–49.91) were independently associated with PPM. A nomogram based on CT features identified at multivariable analysis yielded an AUC of 0.92 (95% CI: 0.85–0.98) for the diagnosis of PPM vs. PDAC. Abstract Purpose: To report the computed tomography (CT) features of pancreatic parenchymal metastasis (PPM) and identify CT features that may help discriminate between PPM and pancreatic ductal adenocarcinoma (PDAC). Materials and methods: Thirty-four patients (24 men, 12 women; mean age, 63.3 ± 10.2 [SD] years) with CT and histopathologically proven PPM were analyzed by two independent readers and compared to 34 patients with PDAC. Diagnosis performances of each variable for the diagnosis of PPM against PDAC were calculated. Univariable and multivariable analyses were performed. A nomogram was developed to diagnose PPM against PDAC. Results: PPM mostly presented as single (34/34; 100%), enhancing (34/34; 100%), solid (27/34; 79%) pancreatic lesion without visible associated lymph nodes (24/34; 71%) and no Wirsung duct enlargement (29/34; 85%). At multivariable analysis, well-defined margins (OR, 6.64; 95% CI: 1.47–29.93; p = 0.014), maximal enhancement during arterial phase (OR, 6.15; 95% CI: 1.13–33.51; p = 0.036), no vessel involvement (OR, 7.19; 95% CI: 1.512–34.14) and no Wirsung duct dilatation (OR, 10.63; 95% CI: 2.27–49.91) were independently associated with PPM. The nomogram yielded an AUC of 0.92 (95% CI: 0.85–0.98) for the diagnosis of PPM vs. PDAC. Conclusion: CT findings may help discriminate between PPM and PDAC.

Abstract
Background Metastatic renal cell cancer is a heterogeneous disease due to its diverse morphological features, the prognostic categories based on clinical criteria. Sometimes indolent course without any significant symptoms can be differentiated before the introduction of novel targeted agents. This observation led to interest in a strategy of deferring systemic therapy in the era of effective systemic therapies. Case presentation We report of a 78-year-old Moroccan man with pancreatic metastasis from renal cell carcinoma which occurred 14 years from right nephrectomy. Indolent disease based on body computed tomography imaging with 4 years follow-up was recognized. Active surveillance with deferred antiangiogenic multikinase inhibitor at disease progression was proposed. Nowadays, the patient is under oncological follow-up, he is in a good state of health, and he is disease-free for 48 months from the diagnosis of the tumor and for 20 months from the start of the treatment with Sunitinib Conclusions Active surveillance before target therapy may be a suitable approach to ensure long progression-free survival with minimal side-effects and better quality of life in asymptomatic, low-volume, metastatic disease. Further prospective studies with biomarker validation are required to define the patients most likely to benefit from this approach.

Abstract
BACKGROUND Pancreatic masses may seldom represent a metastasis or secondary involvement by lymphoproliferative disorders. Recognition of this uncommon occurrence may help render an accurate diagnosis and avoid diagnostic pitfalls during endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). In this study, we review our experience in diagnosing secondary tumors involving the pancreas. MATERIALS AND METHODS The electronic database of cytopathology archives was searched for cases of secondary tumors involving the pancreas at our institution and a total of 31 cases were identified. The corresponding clinical presentations, imaging study findings, cytological diagnoses, the results of ancillary studies, and surgical follow-up, if available, were reviewed. RESULTS Nineteen of the patients were male and 12 female, with a mean age of 66 years. Twenty-three patients (74%) had a prior history of malignancy, with the latency ranging from 6 months to 19 years. The secondary tumors involving the pancreas included metastatic carcinoma (24 cases), metastatic sarcoma (3 cases), diffuse large B-cell lymphoma (2 cases), and plasma cell neoplasm (2 cases). The most common metastatic tumors were renal cell carcinoma (8 cases) and lung carcinoma (7 cases). Correct diagnoses were rendered in 29 cases (94%). The remaining two cases were misclassified as primary pancreatic carcinoma. In both cases, the patients had no known history of malignancy, and no ancillary studies were performed. CONCLUSIONS Secondary tumors involving the pancreas can be accurately diagnosed by EUS-FNA. Recognizing uncommon cytomorphologic features, knowing prior history of malignancy, and performing ancillary studies are the keys to improve diagnostic performance and avoid diagnostic pitfalls.

Abstract
Currently, ultrasound (US), computed tomography (CT) and Magnetic Resonance imaging (MRI) represent the mainstay in the evaluation of pancreatic solid and cystic tumors affecting pancreas in 80-85% and 10-15% of the cases respectively. Integration of US, CT or MR imaging is essential for an accurate assessment of pancreatic parenchyma, ducts and adjacent soft tissues in order to detect and to stage the tumor, to differentiate solid from cystic lesions and to establish an appropriate treatment. The purpose of this review is to provide an overview of pancreatic tumors and the role of imaging in their diagnosis and management. In order to a prompt and accurate diagnosis and appropriate management of pancreatic lesions, it is crucial for radiologists to know the key findings of the most frequent tumors of the pancreas and the current role of imaging modalities. A multimodality approach is often helpful. If multidetector-row CT (MDCT) is the preferred initial imaging modality in patients with clinical suspicion for pancreatic cancer, multiparametric MRI provides essential information for the detection and characterization of a wide variety of pancreatic lesions and can be used as a problem-solving tool at diagnosis and during follow-up.

Abstract
Background Metastases from breast cancer cause the frequent involvement of lung, bone, liver, and brain, while the occurrence of metastases to the gastrointestinal tract is rare, and more frequently discovered after a primary diagnosis of breast cancer. Solitary pancreatic metastases from breast cancer, without widespread disease, are actually unusual, and only 19 cases have been previously described; truly exceptional is a solitary pancreatic metastasis becoming evident together with the primary breast cancer. Case presentation A 68-year-old woman reported general fatigue, lethargy, and jaundice. Abdominal ultrasound (US) and magnetic resonance imaging (MRI) showed an ampulloma of Vater’s papilla; moreover, a neoplastic nodule in the left breast was diagnosed. She underwent surgery for both breast cancer and ampulloma of Vater’s papilla. Pathological examination of pancreatic specimen, however, did not confirm primary carcinoma of the duodenal papilla, but showed a metastatic involvement of pancreas from lobular breast cancer. Immunohistochemistry has been essential to confirm the origin of the malignancy: hormone receptors and mammaglobin were expressed in both the primary breast tumor and the pancreatic metastasis. Conclusions This is one of the few reported cases in literature of an isolated and synchronous pancreatic metastasis from breast cancer, where the definitive diagnosis was obtained only after surgery. We discuss the controversies in this diagnosis and the choice of correct treatment. The surgical resection of solitary metastases can be performed in the absence of disseminated disease.

Abstract
Metastatic lesions of the pancreas are uncommon, accounting for approximately 2% of pancreatic malignancies. Many tumours involve the pancreas secondarily and may manifest with different clinical and imaging characteristics. Although many patients have widespread disease, isolated metastases can be found. Surgical management is associated with improved survival in these cases. The experience of the pancreatic surgery unit and imaging department of our hospital in many patients presenting with pancreatic metastases is presented, and a review of the recent literature is undertaken. Main Messages • The early recognition of secondary pancreatic tumours on US, CT and MRI is extremely important. • Pancreatic metastases may mimic primary pancreatic adenocarcinoma or induce acute pancreatitis. • Most pancreatic metastases are discovered on a CT examination performed for follow-up.

Abstract
OBJECTIVE The objective of this study was to assess the ability to detect pancreatic metastasis of lung cancer and to clarify the degree of fluorodeoxyglucose (FDG) accumulation and computed tomography (CT) characteristics of pancreatic metastasis from lung cancer. METHODS A total of 573 patients (415 men and 158 women) with lung cancer were retrospectively evaluated. All patients underwent FDG-positron emission tomography (PET)/CT with contrast-enhanced CT for first=stage (313 patients; initial study group) or follow-up study (260 patients; follow-up study group). A lesion was regarded as positive for metastasis on the basis of visual judgment of the degree of increased metabolism by two experienced and independent interpreters, supported by semiquantitative evaluation on the basis of calculation of the maximum standardized uptake value (SUV(max)). RESULTS Abnormal accumulations in the pancreas were detected in 5 of 313 patients (1.60%) in the initial study group, and 6 of 260 patients (2.31%) in the follow-up study group. Seven of these patients had adenocarcinoma, three had small cell carcinoma, and the rest had large cell endocrine carcinoma. Tumor sizes (longitudinal diameter), measured by CT, of these 11 patients ranged from 6 mm to 52 mm (mean +/- SD 8.3 mm +/- 11.9 mm), and SUV(max) for 1 h ranged from 3.37 to 11.1 (mean +/- SD 6.12 +/- 2.43). Three of these pancreatic lesions were difficult to determine by routine transaxial images, and detection was obvious only by thin-slice images or multiplanar reconstruction images. Contrast-enhanced CT showed gradual fill-in from the peripheral portion to the center. In addition, 10 of 11 cases did not show main pancreatic duct dilatation even if the tumor size was large. CONCLUSIONS Metastases to the pancreas in lung cancer patients are not so rare and radiologists first have an important role to detect the pancreatic mass and then suggest to metastasis as the likely diagnosis. For this purpose, FDG-PET/CT has an advantage in depicting unsuspected pancreatic metastasis from lung cancer, particularly that which is not detected by CT alone.

Abstract
BACKGROUND Unlike primary pancreatic carcinoma, metastases to the pancreas are rare, and their resection may be performed as palliative treatment. The aim of this study was to review our experience with the operative management of pancreatic metastases. MATERIALS AND METHODS Between January 1994 and December 2004 13 patients (nine women and four men; median age: 59 years; range: 36-79 years) were admitted to our institution with metastatic lesion to the pancreas. The clinical features of the treatment and results were examined. RESULTS Primary tumors were renal cell carcinoma (n=5), lobular carcinoma of the breast (n=3), endometrioid carcinoma of the ovary (n=1), colonic adenocarcinoma (n=1), jejunal leiomyosarcoma (n=1), melanoma (n=1), and non-small-cell lung cancer (n=1). The median interval between primary tumor and pancreatic metastases was 36 months (range: 5-192 months). Six patients (46%) were asymptomatic, while the other seven patients presented with jaundice, pain, and duodenal obstruction. Two patients with extrapancreatic disease underwent palliative surgery, and the remaining 11 patients underwent operative procedures that included seven pancreaticoduodenectomy and four distal pancreatectomies with splenectomy. Postoperative mortality was nil, and the morbidity rate was 30%. The two patients who underwent palliative surgery died after 7 and 9 months, respectively. The median survival of the resected patients was 26 months (range: 13-95 months). Five patients died of disease, eight are alive at the time of this report. CONCLUSION A trend towards improved survival, even if not statistically significant, was observed in the renal carcinoma patients reported here. Surgical resection can be performed safely in selected patients with isolated metastases to the pancreas, achieving long-term survival as well as good palliation.

Abstract
OBJECTIVES A clinicopathologic presentation of 2 unusual cases of metastatic mesenchymal neoplasms in the pancreas. METHODS The first case concerns a 26-year-old man with a history of intracranial mesenchymal chondrosarcoma (since the age of 17), 2 left lung operations, and 3 right thigh operations. Distal pancreatectomy and splenectomy was performed because of suspicious mass in the pancreas. The second case concerns a 66-year-old woman with a history of uterus leiomyosarcoma (10 years ago) with left axillary and right femoral metastases. She underwent distal pancreatectomy and splenectomy because of suspicious mass measuring 4 x 4 cm, in the pancreatic body. RESULTS In the first case, the pathological examination revealed a tumor measuring 3.8 x 3.5 cm and histologically compatible with mesenchymal chondrosarcoma, developing in a vessel lumen and invading into the pancreatic parenchyma. In the second case, the pathological examination showed metastatic leiomyosarcoma of high-grade malignancy. The incidence of metastatic pancreatic tumors has been reported to be only 1.6% to 3%. Most of these tumors were of epithelial origin, and the most common sites of the primary lesions were the lung, kidney, and gastrointestinal tract. CONCLUSIONS The cases of metastatic uterus leiomyosarcoma and the metastatic intracranial chondrosarcoma are, to our knowledge, the first to be described.

Abstract
Pancreatic or gastric metastases from other primary malignancies are rare, especially from leiomyosarcoma. We report a case of leiomyosarcoma in the left lower leg with metastases to the pancreas and stomach. A 61-year-old man had liver cirrhosis caused by hepatitis C virus infection and was followed up by his primary physician. Two years before presentation at our hospital, he had undergone surgical resection of leiomyosarcoma in the left lower leg and systemic chemotherapy for multiple metastatic tumors in the lung. On admission, endoscopic examination and computed tomography were performed for a routine checkup to exclude esophageal varices and liver tumor. Although the patient had no specific symptoms, multiple gastric and pancreatic metastases were identified by endoscopy and computed tomography, respectively. In general, metastases to the pancreas and stomach are rare. We discuss the clinical and diagnostic findings of pancreatic and gastric metastases by reviewing previously reported cases.

Abstract
BACKGROUND The aim of the study is to analyze pancreatic metastases and their clinical, radiological, therapeutic and prognostic features. METHODS Three cases of pancreatic metastases observed and a world literature review of 333 cases were recorded. RESULTS Pancreatic metastases are due more frequently to renal cell carcinoma; they are usually metachronous and characterized by a long period of time between the resection of the primary tumor and their detection. The differential diagnosis with other pancreatic masses is difficult, but an accurate anamnesis, some peculiar findings of imaging techniques and percutaneous fine needle aspiration could allow preoperative diagnosis. Pancreatic resections are the treatment of choice allowing the better palliation and improving survival. 150/234 pancreatic metastases underwent pancreatic resections (resectability index = 64.1%); 88/132 patients are alive with a mean follow-up of 27.1 months; of the 44 dead patients the mean survival time was 21.3 months. Among pancreatic metastases the primary tumor with better prognosis is renal cell carcinoma. CONCLUSION Pancreatic metastases are rare; their preoperative diagnosis is difficult but useful and possible. Surgical resection is suggested because the patient still may have a prolonged survival.

Abstract
BACKGROUND AND OBJECTIVES The incidence of metastases to the pancreas is very low. The benefit of resection of pancreatic metastasis is poorly defined. In this review we evaluated the outcome of patients undergoing pancreatic resection for metastatic tumors to the pancreas. METHODS Eight patients underwent pancreatic resection for metastatic tumor from December 1980 to June 2001. The primary cancer was colon carcinoma (n = 4), renal cell cancer (n = 2), duodenal leiomyosarcoma (n = 1), and malignant fibrous histiocytoma (n = 1). The median interval between primary treatment and detection of pancreatic metastases was 36 months. In two cases pancreatic metastases were synchronous with the primary tumor. RESULTS Four patients underwent pancreatoduodenectomy, two distal pancreatectomy, one total pancreatectomy, and one median pancreatectomy. Associated resection of extrapancreatic lesions was performed in four patients, including two left hepatectomy and two left colectomy. There was no postoperative mortality, but two patients had a pancreatic and a biliary fistula, respectively. Survival averaged 23 months (range 14-42 months): four patients died for metastatic disease from 14 to 42 months after operation, while four patients are alive and well 14 to 31 months after surgery. CONCLUSIONS Pancreatic resection for metastatic disease to the pancreas should be considered even in selected patients with limited extrapancreatic disease. Long-term survival or good palliation may be achieved.

Abstract
To investigate the clinicopathological features of patients with secondary tumors of the pancreas, we reviewed autopsy records and pathological features of 103 cases with pancreatic secondary tumors from 690 cases of malignant tumors (excluding cases of primary pancreatic cancer) over a 10-year period. There were 67 men and 36 women in the study, ranging in age from 2 to 94 years (mean: 61 years). The incidence of pancreatic secondary tumors was 15% in the autopsy cases of malignant tumors, and the majority of the secondary tumors were carcinomas. The stomach was the most common primary tumor site (20%), followed by the lung (18%) and extrahepatic bile duct (13%). Because the total number of each primary carcinoma differed, we paid specific attention to the incidence of pancreatic metastasis in each primary carcinoma. We found that carcinoma of the papilla of Vater showed the highest rate of incidence (75%) of pancreatic metastasis in each type of primary carcinoma. Approximately half of the metastatic lesions were solitary, but the metastatic lesions in the pancreas could not be identified macroscopically in 34 cases (33%). Histologically, the most common carcinoma was adenocarcinoma, followed by large cell carcinoma, small cell carcinoma and neuroendocrine carcinoma. The most common non-epithelial tumor was leukemia, followed by malignant lymphoma. Undifferentiated carcinoma and neuroendocrine carcinoma were often found in cases of extrahepatic bile duct or urinary bladder carcinoma with pancreatic metastasis. As for the microscopic infiltration patterns of tumor cells, 73% of cases showed an interlobular and intralobular infiltration. Fat necrosis was most frequently seen as an associated pathological finding (19%). Our study indicates that secondary tumors of the pancreas can be found in approximately one out of six to seven autopsy cases of malignant tumors, and in Japan, the most common of these is adenocarcinoma of the stomach.

Abstract
BACKGROUND Clear cell carcinomas of the pancreas are rare and more likely represent metastatic renal cell carcinoma (RCC). METHODS 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. RESULTS 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). CONCLUSIONS 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.

Abstract
OBJECTIVE To review the clinical features, computed tomographic (CT) appearance, and treatment outcomes in a case series of patients with renal cell carcinoma (RCC) metastatic to the pancreas. PATIENTS AND METHODS We retrospectively reviewed the records of 23 patients (15 men and 8 women) with RCC metastatic to the pancreas, detected by CT examination between 1986 and 1996. All patients had undergone a previous nephrectomy for RCC. RESULTS Isolated mild elevation in liver function test results (in 5 patients) or in serum amylase level (in 8 patients) was observed. New-onset diabetes was detected in 3 patients. The CT characteristics of the pancreatic metastases generally resembled those of primary RCC with well-defined margins and greater enhancement than normal pancreas with a central area of low attenuation. The mean interval between resection of the primary RCC and detection of the pancreatic metastases was 116 months (range, 1-295 months). In 18 patients (78%), the pancreatic metastases were diagnosed more than 5 years after nephrectomy. The pancreas was the initial metastatic site in 12 patients (52%). Survival was shortened with higher tumor grade (mean survival time of 41 months and 10 months in patients with grade 2 and 3, respectively). Surgical resection was carried out in 11 patients (7 distal and 3 total pancreatectomies and 1 distal pancreatectomy followed 4 years later by total pancreatectomy), with 8 patients alive at a mean follow-up of 4 years, 6 of whom remained free of recurrence. Overall, 12 patients (52%) were alive at a mean of 42 months after diagnosis of metastatic disease. CONCLUSIONS The appearance of metastatic RCC lesions in the pancreas closely resembles the appearance of primary RCC on CT images. Pancreatic metastases from RCC are frequently detected many years after nephrectomy. Patient survival correlates with tumor grade. Histologic analysis of pancreatic masses in patients with a history of resected primary RCC is important since the prognosis for RCC metastatic to the pancreas is much better than that for primary pancreatic adenocarcinoma.

Abstract
In nearly 25% of patients with primary renal-cell carcinoma, metastasis is not uncommon and usually does not give rise to difficulties in diagnosis. However, its presentation as a mass in the head of the pancreas following an elapse of several years after the initial diagnosis of renal carcinoma is not only uncommon but may be confused clinicoradiologically with a primary pancreatic adenocarcinoma. The case presented here illustrates such an example with an emphasis on the usefulness of fine-needle aspiration cytology (FNAC) in the diagnosis.

Abstract
The pancreas is a rare site of metastasis from renal cell carcinoma (RCC). We present herein the case of a 47-year-old male in whom a solitary pancreatic metastasis was treated by a pylorus-preserving pancreatoduodenectomy (PpPD), 3 years after a radical nephrectomy for a RCC. The few reported cases of surgically treated pancreatic metastases from RCC are reviewed following the presentation of this case.

Abstract
To verify the influence of obstructive jaundice on pancreatic growth, the anteroposterior width of the pancreas was measured by computed tomography in 30 cholangiocarcinoma patients excluded patients with distal bile duct tumor (jaundice group) and 74 control subjects. Follow-up examinations were performed on 12 patients with and without internal biliary drainage to elucidate the temporal relationship between pancreatic enlargement and the diversion of the obstructed biliary stream. Histologic analysis on autopsy samples from 13 control and 10 jaundice cases also was performed. Mean pancreatic head and body widths in the jaundice group were 2.93 +/- 0.3 cm and 2.01 +/- 0.3 cm, respectively. These values were significantly greater than those of the controls (2.13 +/- 0.3 cm and 1.49 +/- 0.3 cm, P < 0.01). The glandular widths returned to their normal sizes following internal biliary drainage. No changes were seen in patients who underwent external drainage alone. Histologic examination revealed that enlargement of the acinar cells or of the islet of Langerhans was often seen in the jaundiced patients. Therefore obstructive jaundice is thought to cause pancreatic growth through a trophic effect by interrupting biliary circulation.

Abstract
There is relatively little information concerning the use of fine-needle aspiration biopsy (FNAB) to diagnose a mass in the pancreas that is secondary to metastatic tumor. This study reviews the incidence and types of neoplasms which metastasize to the pancreas and assesses the contribution FNAB can make in their diagnosis. Of 117 radiologically guided FNABs of the pancreas, 11% (n = 13) showed metastatic malignancy. Nine patients had a previous history of malignancy while four patients presented with a pancreatic mass and were subsequently found to have wide-spread malignant disease. The majority of metastatic lesions were epithelial (77%, n = 10). Patient outcomes were generally poor (mean survival 2.8 mo). Metastases to the pancreas occur from a variety of primary sites and should be considered in patients with a pancreatic mass and a history of prior malignancy. FNAB is useful in diagnosing these metastases and this is clinically important because of their poor prognosis.
