INTRODUCTION: Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas. PRESENTATION OF CASE: A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma...

BACKGROUND: In veterinary medicine, contrast-enhanced ultrasonography allowed the accurate quantification of liver, splenic and kidney vascularization in healthy dogs and the differentiation between malignant and benign hepatic, renal, and splenic nodules in dogs and cats based on perfusion patterns. The utility of contrast-enhanced ultrasonography in other applications is still under study. The aim of this study was to develop diagnostic criteria by contrast-enhanced ultrasonography in 8 client-owned adult dogs affected by urinary bladder transitional cell carcinoma with definitive diagnosis made by cytopathologic evaluation after suction biopsy...

Renal diseases are driven by alterations in the entity of proteins within the kidney, at the level of single cells, nephron subunits (such as glomerulus and tubule), tissues and body fluids. Histologically, kidney diseases are extremely heterogeneous. Mass-spectrometry based proteomics provides a unique opportunity to interrogate heterogeneity and dynamics of various proteome layers within the kidney to better understand physiology and pathophysiology, and to translate signaling networks into therapies. Yet, the success of this endeavor will largely depend on improving proteomic data acquisition methods toward increased reproducibility...

Synchronous primary cancers involving the pancreas and kidney are extremely rare and poorly documented. We report the first case of this association treated with chemotherapy and tyrosine kinase inhibitor. A 70-year-old woman presented with a 2-month history of epigastric pain with weight loss of 12 kg. Two weeks previously, she had presented with jaundice and pelvic pain. A computed tomography (CT) scan of the body revealed the presence of an irregular mass in the body of the pancreas, encasing the celiac trunk, with dilatation of the biliary tract...

Renal cell carcinoma (RCC) is a common malignancy with high metastatic potential, primarily due to its extensive vascularity. Common sites of metastasis include lungs, bone, lymph nodes, liver, and brain. However, rare cases of metastasis to other sites including inguinal lymph nodes, peritoneum/mesentery, and orbit have been published in the literature. Herein, a unique case involving metastasis of RCC to the uvula is presented. The patient is a 55-year-old White female with a past medical history of stage 3 (T3aN0M0) RCC s/p nephrectomy 3 years prior to presentation...

We report a rare case of squamous cell carcinoma (SCC) of the nasal cavity arising in a patient with granulomatosis with polyangiitis (GPA). The patient was a 35-year-old man who had been diagnosed 15 years earlier with GPA and treated medically for sinonasal, pulmonary, and renal involvement. He presented to us with left-sided orbital and cheek pain and nasal obstruction. Endoscopy detected a friable, exophytic mass that involved the left lateral nasal wall and septum. Biopsy analysis identified the mass as an SCC...

Body mass index(BMI)>35-40kg/m2 is often a contraindication, while Roux-en-Y gastric bypass(RYGB) is performed to enable kidney transplantation. This single-center retrospective study evaluated pre- and post-transplant outcomes of 31 morbidly obese end-stage-renal-disease patients having RYGB before kidney transplantation between July,2009-June,2014. Fourteen RYGB patients were subsequently transplanted. Nineteen recipients not having GB with a BMI>36kg/m2 at transplantation were used as historical controls...

The incidence of small renal masses ≤4 cm is increasing due to the widespread use of cross-sectional imaging. The majority of these represent indolent forms, but the risk for developing metastases is reported in up to 6% of patients. Particularly in old and comorbid patients surgery might be harmful overtreatment. Thus, there is an increasing demand to establish oncologically safe active surveillance protocols. Radiographic or biopsy-based biological markers to appropriately designate candidates for active surveillance are currently the focus of research...

A 66-years-old woman was referred to our hospital with the chief complaint of a huge exposed left breast mass, associated massive exudates, bleedingand foul-smelling discharge. Invasive ductal carcinoma was diagnosed by core needle biopsy. The computed tomography showed left axillary lymph node metastases and no distant metastasis. Her performance status(PS) was Grade 3. She had serious comorbidities such as non-alcoholic steatohepatitis and liver cirrhosis, renal dysfunction. DMpC therapy and Mohs paste therapy were started since her overall status was improved...

Recent advances in high-throughput sequencing for clinical genetic testing have revealed novel disease-causing genes, such as Crumbs homolog 2 (CRB2) for early-onset steroid-resistant nephrotic syndrome (SRNS). We report the long-term clinicopathologic observation of a Japanese female patient with SRNS caused by a newly identified compound heterozygous mutation of CRB2 (p.Arg628Cys and p.Gly839Trp located in the 10th and 11th epidermal growth factor-like domains, respectively). She was initially examined during a mass urinary mass screening for 3...

Amyloidosis is a disorder characterized by the deposition of abnormal protein fibrils in tissues. Leukocyte cell-derived chemotaxin 2-associated amyloidosis is a recently recognized entity and is characterized by a distinctive clinicopathologic type of amyloid deposition manifested in adults by varying degrees of impaired kidney function and proteinuria. There are only a limited number of cases reported in the literature. We present a 64-year-old Hispanic female with a history of hypertension who was referred for chronic kidney disease management...

Metastases to the pancreas account for less than 5 percent of all malignancies affecting the pancreas. The most common secondary malignancy of the pancreas is renal cell carcinoma. We report a patient presented with abdominal pain and weight loss. Computed tomography (CT) imaging showed pancreatic head mass. Biopsy from the mass showed prostate metastasis after 13 years from radical prostatectomy and Leuprolide therapy. This case demonstrates a rare location for prostate metastasis which was the pancreas. To our knowledge there are only six cases reported in literature...

Renal mass biopsy is still controversial due to imperfect accuracy(1). Raman spectroscopy (RS) demonstrated promise as an in vivo real-time, non-destructive diagnostic tool in many malignancies. Short wave infra-red (SWIR) RS has the potential to improve on previous RS systems for renal mass diagnosis. The aim of this study is to evaluate a SWIR RS system in differentiating normal and malignant renal samples Measurements were acquired using a benchtop RS system with excitation wavelength at 1064 nm and an InGaAs array detector...

Renal cell cancer is nowadays predominantly diagnosed in early stages due to the widespread use of sectional imaging for unrelated symptoms. Small renal masses (<4 cm) feature a largely indolent biology with a very low risk for metastasis or even a benign biology in up to 30% of the cases. Consequently, there is a need for less invasive therapeutic alternatives to nephron-sparing surgery. Meanwhile, there is a broad portfolio of local ablation techniques to treat small renal tumors. These include the extensively studied radiofrequency ablation and cryoablation techniques as well as newer modalities like microwave ablation and irreversible electroporation as more experimental techniques...
