Résumé
Two percent of all malignant pancreatic tumors are metastases from other primaries, with small cell lung cancer, colorectal cancer, breast cancer and hematological neoplasms being the commonest. Renal cell carcinoma (RCC) metastasizing to the pancreas is rare and occurs in 2.8% of patients with metastatic RCC. However, RCC is the most common primary leading to solitary pancreatic metastasis. Metastases often present many years after nephrectomy for primary RCC (median time of 8 years) and should therefore be looked for on surveillance or when patients present with upper abdominal symptoms. Complete surgical resection when possible offers the best chance for cure.

Oral lesions of tuberculosis though uncommon, are seen in both the primary and secondary stages of the disease. In secondary tuberculosis, the oral manifestations may be accompanied by lesions in the lungs, lymph nodes, or in any other part of the body and can be detected by a systemic examination. Primary oral tuberculosis may present as a diagnostic challenge for the clinician. Here we report two patients with primary tuberculosis in the oral cavity who presented to the dental department, were diagnosed and referred for medical management.

This is a case report of a 29 year old woman who presented with painless and progressive obstructive jaundice. Imaging investigations of the abdomen revealed a tumour of the common bile duct. She was treated by complete excision of the bile duct and hepaticojejunostomy. The histopathology report of the tumour read as benign schwannoma.

Retroperitoneal soft tissue sarcomas are difficult to treat because the retroperitoneal organs and great vessels are often involved by the time the patients come to a surgeon. We present the case of a 48 year old woman with a retroperitoneal leiomyosarcoma that had infiltrated the IVC and the renal veins.
